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.

さくなるように設定されている。 This coiled spring 3 makes the angle formed by each linear portion 3b, 3c greater than the angle in the natural state (no load state) so that it can always exert a biasing force from the fully closed state to the fully open state of the lid 2. It is set to always decrease by an appropriate amount.

b,3cの開度を小さくされてその付勢力を増大
させる。一方、さらに、蓋2を開放していくと、
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.

方向に回転駆動するようになつている。 In other words, when the other end of the coiled spring 3 is located on the straight line formed by the point on the central axis of the pin 4 and one end of the coiled spring 3 (neutral state), the opening degree of the lid 2 is increased. If is small, the coiled spring 3 will close to the lid 2.
Rotate the lid in the fully closed direction, and conversely close the lid 2 from the neutral state.
When the degree of opening is large, the coiled spring 3 rotates the lid 2 in the fully open direction.

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.

問題点となつている。 On the other hand, in the conventional automobile ashtray with a spring-biased opening/closing lid device shown in FIG.
Since the two concave curved portions 9 and 10 are required, the biasing surface portion 6c requires a certain length or more, making the leaf spring 6 large, which poses a problem in terms of space utilization.

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.
