Electric junction box

1. An electric junction box comprising:

a box main body;

a tubular guide portion projecting from the box main body and guiding a plurality of electric wires to an outside of the box main body, said tubular guide portion having an expanded portion gradually expanded toward an outside of the guide portion as the guide portion is extended from the box main body to a tip portion away from the box main body; and

an adhesive tape as a fixing member continuously wound from the guide portion to the electric wires while the electric wires are passed through an inside of the guide portion,

wherein the guide portion is provided with a plurality of ribs formed away from the tip portion along a direction in which the electric wires are passed, projecting outward from the guide portion and the adhesive tape being wound directly, in spirals, over the plurality of ribs, and wherein the rib is provided on a whole circumference of wound portions.

2. The electric junction box as claimed in claim 1 ,

wherein the guide portion includes: a gutter-shaped portion extended from an edge of a bottom side of the main body portion; and a bottom wall portion extended from an edge of a lower cover which is overlapped with the edge of the bottom side of the main body portion, and

wherein when the lower cover is attached to the main body portion, edges of the gutter-shaped portion and the bottom wall portion in a circumferential direction are overlapped with each other to compose the rectangular-tubular-shaped guide portion.

3. The electric junction box as claimed in claim 2 ,

wherein the gutter-shaped portion includes: a plate-shaped ceiling wall portion; and a pair of plate-shaped side wall portions extended from both edges of the ceiling wall portion in a circumferential direction, and arranged with a gap to each other.

4. The electric junction box as claimed in claim 3 ,

wherein the ceiling wall portion includes: a base portion continued to the main body portion; and a first wound portion continued to the main body portion away from the box main body, and

wherein the first wound portion is inclined in a direction separating from the lower cover and approaching the upper cover as the first wound portion extends from a base end of the first wound portion near the box main body to a tip portion of the first wound portion away from the box main body.

5. The electric junction box as claimed in claim 4 ,

wherein the pair of side wall portions respectively includes: a pair of second base portions continued to the base portion; and a pair of second wound portions continued to both the base portion and the second base portions and the first wound portion, and

wherein respective edges of the second wound portions away from the ceiling wall portion are inclined in a direction approaching the ceiling wall portion as the edges of the second wound portions extend from base ends of the second wound portions near the box main body to the tip portion.

6. The electric junction box as claimed in claim 5 ,

wherein one of the second wound portions is provided with the expanded portion gradually expanded toward an outside of the guide portion as the second wound portion is extended from the base end of the second wound portion to the tip portion, and

wherein an outside size in a width direction of the guide portion perpendicular to a longitudinal direction of the guide portion at the tip portion is larger than a size between the second wound portions at the base end of the second wound portion.

7. The electric junction box as claimed in claim 6 , wherein the expanded portion is formed on wound portions, and a size in a width direction of the guide portion at the tip portion is larger than that at the base ends of the second wound portions.

8. The electric junction box as claimed in claim 1 , wherein the expanded portion is formed on wound portions, and a size in a width direction of the guide portion at the tip portion is larger than that at the base ends of the wound portions.

9. The electric junction box as claimed in claim 2 ,

wherein the bottom wall portion includes: a flexible portion continued to the lower cover; and a third wound portion continued to the flexible portion,

wherein a thickness of the flexible portion is elastically deformable both inward and outward of the guide portion,

wherein when the flexible portion is not deformed, an inner radius of the guide portion is formed to fit in a minimum case of a radius of the electric wires, and

wherein when the flexible portion is deformed outward of the guide portion, and the third wound portion is pushed in a direction increasing the radius of the guide portion by the electric wires.
