Clip

1. A clip to be inserted into, and fixed to, a rectangular hole formed in an attached member, the clip comprising:

a base body portion that engages the rectangular hole on one side of the attached member;

a stem portion that extends from the base body portion to be insertable into the rectangular hole; and

a pair of engaging legs that extend from an end portion of the stem portion toward the base body portion in an anchor leg-like manner,

wherein engaging portions are disposed in ends of the engaging legs, respectively, to engage with the rectangular hole on an other side of the attached member,

wherein widths of the engaging legs are formed to be gradually enlarged from the end portion of the stem portion toward the base body portion,

wherein each of the engaging legs comprises:

a straight portion that extends at a substantially constant width from the base portions of said each of the engaging legs toward end portions of said each of the engaging legs; and

a widened portion, having a different thickness from, and attached to, said straight portion, and

wherein said widened portion extends from at least one side of the straight portion of said each of the engaging legs to be gradually enlarged toward the end portions of said each of the engaging legs, and

wherein outer side faces of the widened portion are formed to bend toward the stem portion rather than outer side faces of the straight portion.

2. The clip according to claim 1 , wherein widths of end portions of the engaging legs are 1.2 times wider than widths of base portions of the engaging legs.

3. The clip according to claim 1 , wherein at least one side of the end portions of the engaging legs is in a substantially identical position in a width direction as a base portion of the stem portion.

4. The clip according to claim 1 , wherein the engaging legs are formed to extend at a constant width in a predetermined length range from each of the base portions of the engaging legs, and to be gradually enlarged as advancing from middle portions of the engaging leg toward the end portions of the engaging legs.

5. The clip according to claim 1 , further comprising a rib disposed on the base body portion perpendicular to the stem portion, in a location which the stem portion extends from the base body, opposite to said side of the straight portion.

6. The clip according to claim 5 , wherein width-direction end portions of the widened portion of the engaging legs butt against one side of an inner periphery of the rectangular hole, and the rib butts against an other side portion in an opposite side of the inner periphery of the rectangular hole.

7. The clip according to claim 1 , wherein each of said engaging portions comprises:

a thin piece which elastically engages with an inner periphery of the rectangular hole; and

an engaging step which engages with a rear-face peripheral edge of the rectangular hole.

8. The clip according to claim 1 , wherein a thickness of the widened portion is thinner than a thickness of the straight portion.

9. The clip according to claim 1 , wherein the widened portion has a triangular shape which starts from a middle of the straight portion and extends in a lateral direction.

10. A clip, comprising:

a base body portion;

a stem portion that extends from the base body portion to a direction substantially perpendicular to the base body portion, the stem portion including a stem end portion; and

a pair of engaging legs, each of the engaging legs comprising:

a base portion that is continuous to the stem portion;

an end portion that extends from the base portion toward the base body portion, the end portion being wider than the base portion;

a straight portion that extends at a substantially constant width from the base portion to the end portion; and

a widened portion, having a different thickness from, and attached to, said straight portion,

wherein said widened portion extends from at least one side of the straight portion to be gradually enlarged as advancing from the base portion to the end portion, and

wherein outer side faces of the widened portion are formed to bend toward the stem portion rather than outer side faces of the straight portion.

11. The clip according to claim 10 , wherein each engaging leg is formed to be gradually enlarged as advancing from the base portion to the end portion of the engaging leg.

12. The clip according to claim 11 , wherein a width of the end portion of each engaging portion is 1.2 times wider than a width of the base portion.

13. The clip according to claim 11 , wherein the engaging legs are formed to extend at a constant width in a predetermined length range from the base portions of the engaging legs, and to be gradually enlarged as advancing from a middle portion of the engaging leg toward the end portions of the engaging leg, respectively.

14. The clip according to claim 10 , wherein a thickness of the widened portion is thinner than a thickness of the straight portion.

15. The clip according to claim 10 , further comprising a rib that is formed on the base body portion perpendicular to the stem portion in a location which the stem portion extends from the base body, opposite to said side of the straight portion.

16. The clip according to claim 15 , wherein the base body portion engages with a rectangular hole formed in an attached member on one side of the attached member,

wherein engaging portions are disposed in ends of the engaging legs to engage with the rectangular hole on an other side of the attached member,

wherein width-direction end portions of the widened portion of the engaging legs butt against one side of an inner periphery of the rectangular hole, and the rib butts against an other side portion in an opposite side of the inner periphery of the rectangular hole.

17. The clip according to claim 10 , wherein the widened portion has a triangular shape which starts from a middle of the straight portion and extends in one lateral direction.
