The distance between the temporary fixing portion 62 and the pin 64 is slightly longer than the distance between the winding portion 76 of the spring 70 and the second locking leg 74. Engagement is made such that the bending angle is elastically expanded slightly. This engagement force is applied to the second locking leg 74 in the counterclockwise direction in FIGS. 1 and 3 based on the elastic force of the winding portion 76 when the knob 40 is attached to the front plate 10 and is restored. The second locking leg 74 is set so as to be disengaged from the temporary fixing portion 62 by the force.

This embodiment is constructed as described above.
Therefore, as shown in FIGS. 1 to 3, with the winding portion 76 of the spring 70 fitted in the pin 64 of the knob 40, the spring 7
The second locking leg 74 of 0 is elastically slightly widened, and is engaged with the temporary fixing portion 62. This causes the spring 70
Is prevented from rotating around the pin 64, and the first locking leg 72 in the free state is kept in a position to be engaged with the spring retaining portion 26 of the front plate 10. Therefore, it is not necessary to support the spring 70 by hand in order to keep the first locking leg 72 in the posture of engaging the spring hooking portion 26 when the knob 40 is assembled to the front plate 10.

Further, since a frictional force is generated between the second locking leg 74 and the temporary fixing portion 62 based on the elastic restoring force of the second locking leg 74, the winding portion 76 of the spring 70 is moved from the pin 64 to the winding portion 76. It is prevented from pulling out.

Then, as shown in FIG. 4, the hook portion 52 of the knob 40 is inserted into the openings 24 and 34 of the front plate 10 and the box body 12, and each support piece 46 of the knob 40 is inserted.
Each support shaft 48 is fitted into the shaft support hole 22 of the front plate 10 while elastically deforming. At that time, as shown by a chain double-dashed line in FIGS.
The first engaging leg 72 is engaged with the spring retaining portion 26 of the front plate 10 while being inserted between the spring retaining portion 26 and the spring retaining portion 26.

Further, the first locking leg 72 is provided on the front plate 1.
0 is pressed in the counterclockwise direction in FIG. 1 by the base portion of the spring retaining portion 26, and the winding portion 76 is twisted and the first extending portion 7 is rotated.
Since the angle between the first extension portion 73 and the second extension portion 73 is widened, the second extension portion 73 is moved to the second extension portion 73 by the elastic force of the winding portion 76.
It is rotated counterclockwise, and the second locking leg 74 is disengaged from the temporary fixing portion 62 and engaged with the spring hooking portion 54, as shown by the chain double-dashed line in both figures.

Thus, in this embodiment,
The knob 40 can be easily and quickly attached to the storage box 14 without touching the spring 70 with a fingertip.

After the knob 40 is attached, as shown by the two-dot chain line in FIG. 4, the protrusion 28 prevents the first locking leg 72 from moving in the right direction in the figure, and is shown in FIG. The winding portion 76 of the spring 70 is prevented from coming off the pin 64.

Although the storage box is used as the opening / closing body in the above embodiment, the present invention is not limited to this, and may be a lid for the storage box. In addition, it goes without saying that the present invention can be implemented in a mode in which various modifications are made based on the knowledge of those skilled in the art.

[0029]

As described above, according to the present invention, when the knob is attached to the opening / closing body, the second locking leg of the spring is temporarily fixed to the temporary fixing portion of the knob, so that the spring is pinned. The first locking leg of the spring is kept in a position where it can be engaged with the spring retaining portion of the opening / closing body, and the elastic force that acts on the winding portion of the spring when the knob is attached to the opening / closing body. As a result, the second locking leg disengages from the temporary fixing portion and engages with the spring retaining portion of the knob. Therefore, it is possible to eliminate the need to support the spring with fingertips when attaching the knob, and to improve the attaching work.
