[0002]

2. Description of the Related Art Hinges for doors that open and close an opening of a main body include a hinge that is simple enough to pivot the door and a hinge with a spring that pivots the door and urges the door in the closing direction. For example, a hinge with a spring is used as a hinge of a door of a coin locker in order to urge the unlocked door in the closing direction. Therefore, there is no problem that the door of the coin locker projects in the open state to obstruct a pedestrian, and there is no problem that the door flaps and swings due to the wind or the like.

[0003] When assembling the main body, the fixing work of the hinge and the attaching work of the door complicate the assembling work and cause inefficiency. Therefore, the door after the assembling work of the main body is completed. There is a pin type hinge that can be retrofitted easily. FIG. 6 is a front view showing an example of a pin-type hinge A which can be retrofitted. A bracket 1 formed by bending a metal plate is provided with an upright wall 3 which is bent from both upper and lower ends of a substrate 2. Then, a shaft insertion hole 4 penetrating through one side (the left side in FIG. 6) of the upright wall 3 is provided.

The support shaft 5 inserted into the shaft insertion hole 4 has a length at both ends protruding from the upper and lower standing walls 3, and a flange 6 is provided on the upper side of the support shaft 5. A spring 7 is inserted between the lower standing wall 3 and the lower standing wall 3. In order to retrofit the door D with the pin type hinge A which can be retrofitted as described above to the main body C, the pin type hinge A is attached to the upper part of the door D shown by a chain line in FIG. A pin-shaped lower support shaft (not shown) provided at the lower end of the door D is provided at the lower end edge of the opening of the main body C by being immersed in the shaft insertion hole 4 of the upper standing wall 3 against the spring 7. Insert into the hole.
