When the opening / closing means 2 is closed as shown in FIG. 1, the speed reducing means 4 fitted between the elastic member 31 and the inner side surfaces of the opening / closing means 2, that is, the ball 44 is moved by the elastic restoring force of the spring 43 so that the ball fixing plate. It comes into contact with the curved surface of the hole 62 of 60. Although a part of the ball 44 is exposed through the hole 62, it is in a state of being separated from the deep groove portion 71 formed on the side surface 21 of the opening / closing means 2 by a predetermined distance.

である。If the contact portion 75 comes closer to the ball 44 while the opening / closing means 2 continues to rotate, the ball 44 moves away from the fixing plate 60 as shown in FIG. You will be able to make the maximum close contact. In other words, the maximally compressed spring 4
The repulsive force of 3 acts on the ball 44, and the ball 44 applies the maximum contact force to the contact portion 75.
As a result, the opening speed of the opening / closing means 2 is reduced while giving resistance to the rotation of the opening / closing means 2.
