ようになつている。 The coiled spring 3 consists of a coiled portion 3a and two linear portions 3b, 3c, and the twisting of the coiled portion 3a, that is, the respective linear portions 3b, 3.
A biasing force can be exerted by changing the angle formed with c.

今度は付勢力は徐々に減少する。 For example, when the lid 2 is gradually opened from the fully closed state, the coiled spring 3 is inserted into the locking hole 1d.
Rotate around one end of the side. The pivot axis of the other end of the coiled spring 3 (the end on the locking hole 2a side) is aligned between a point on the central axis of the pin and one end of the coiled spring 3 (the end on the locking hole 1 side).
The coiled spring 3 gradually moves toward each linear portion 3 until it is on a straight line with the pivot axis of the
The opening degrees of b and 3c are reduced to increase their biasing force. On the other hand, as the lid 2 is further opened,
This time, the urging force will gradually decrease.

となつているという問題点がある。 However, in the conventional automobile ashtray with a spring-biased opening/closing lid device shown in FIG. must be set. Therefore, when an attempt is made to close the lid 2, when the opening angle of the lid 2 becomes smaller than β, the lid 2 is automatically closed by the biasing force of the coiled spring 3. During this closing movement, the rotation of the lid 2 is accelerated by the size of the opening angle β, and the lid 2 collides with the locking surface portion 1b on the upper surface of the ashtray body 1 with force, producing a loud impact sound. There is a problem in that the noise is unpleasant to the occupants of automobiles.

持力を確保し難いという問題点もある。 Furthermore, setting the two concave curved portions 9 and 10 formed on one leaf spring 6 to equalize the force for holding the lid 2 in the fully closed and fully open states is as follows:
This is extremely difficult because the spring constants of the leaf springs differ at the positions of the concave curved portions 9 and 10, which have different leg lengths, and it is difficult to secure an appropriate holding force when the lid 2 is fully closed or fully opened. There is also a problem.
