6. The damper of claim 5 , wherein
the leg includes a first region obliquely disposed on the valve body and a second region obliquely disposed from an end portion of the first region, and
the second region overlaps the first region in the first direction.
7. The damper of claim 4 , wherein the leg is arc-shaped.
8. The damper of claim 4 , wherein the leg is tapered-shaped and has a cross section having a ring shape.
9. The damper of claim 4 , wherein, based on the one surface of the valve body, a length of the leg in the first direction is greater than a length of the second protruding portion in the first direction.
10. A damper for a glove box, comprising:
a cylinder including a cylinder body that defines a space therein, a partition that divides the space into a first space and a second space, and a first protruding portion protruding from the partition so that a hole formed in the partition is extended;
a piston disposed in the first space and configured to be movable in a first direction;
a valve disposed in the second space; and
an elastic support unit disposed in the second space to elastically support the valve,
wherein the elastic support unit is in contact with and pressed by the partition due to movement of the piston,
wherein the valve includes a valve body having a plate shape and a second protruding portion protruding from the valve body so that an end portion of the first protruding portion is disposed in the second protruding portion, and
wherein the elastic support unit comprises a coil spring having one side in contact with the valve body and another side in contact with the partition.
11. The damper of claim 10 , wherein the partition includes:
a first plate portion;
a second plate portion disposed apart from the first plate portion in the first direction; and
a connection part connecting the first plate portion to the second plate portion,
wherein the hole is disposed in the second plate portion, and
the one side of the spring is in contact with the second plate portion.
12. The damper of claim 2 , wherein
an orifice is disposed between an outer surface of the first protruding portion and an inner surface of the second protruding portion, and
a size of the orifice changes according to movement of the second protruding portion.
13. The damper of claim 12 , wherein the outer surface of the first protruding portion is an inclined surface having a predetermined inclination.
14. The damper of claim 2 , wherein
the valve includes a protrusion protruding from an outer surface of the valve body,
the cylinder body includes a first guide hole and a second guide hole having different sizes in the first direction. and
the protrusion is disposed in one of the first guide hole and the second guide hole.
15. The damper of claim 14 , wherein
a size of the second guide hole in the first direction is greater than a size of the first guide hole in the first direction, and
a separation distance from the partition to the first guide hole is equal to a separation distance from the partition to the second guide hole.
16. The damper of claim 15 , wherein
the cylinder body includes a third guide hole,
a size of the third guide hole in the first direction is greater than the size of the second guide hole in the first direction, and
a separation distance from the partition to the third guide hole is equal to the separation distance from the partition to the second guide hole.
17. The damper of claim 1 , wherein a cross-sectional area of the cylinder decreases from one end toward the other end of the cylinder.
18. A glove box comprising:
a glove box body in which form a storage space is formed and a cover; and
the damper for a glove box of claim 1 ,
wherein the glove box body is rotatably disposed in a dashboard of a vehicle, and
the damper for a glove box adjusts a movement speed of the glove box body.
19. A damper for a glove box, comprising:
a cylinder including a cylinder body that defines a space therein, a partition that divides the space into a first space and a second space, a first protruding portion protruding from the partition so that a hole formed in the partition is extended, and a plurality of guide holes disposed in the cylinder body to expose the second space;
