Here, the operation of the embodiment of the present invention will be described.
In the embodiment of the present invention, since the ball plunger 50 presses the movable member 30 against the sliding contact surface 42c by biasing the ball 52 with the spring 53, the force of the spring 53 biasing the ball 52 causes the movable member 30 to move. The operating load can be determined. Therefore, even if the force of the spring 53 is increased, the ball 52 rotates with respect to the movable member 30. Therefore, compared with the case where the surface pressure of the leaf spring is increased (compared to the conventional case), the operation load of the movable member 30 is increased. Can be suppressed. Therefore, even if the spring 53 force is increased to such an extent that play of the movable member 30 and generation of abnormal noise can be suppressed when the sliding amount of the movable member 30 with respect to the fixed member 20 is increased, the surface pressure of the leaf spring is increased. Compared with the case of (in comparison with the prior art), an increase in the operation load of the movable member 30 can be suppressed (the slide operation of the movable member 30 can be performed smoothly).

  Further, since the position of the ball plunger 50 can be adjusted in the direction of approaching / separating from the sliding contact surface 42c with respect to the member provided with the ball plunger 50, the ball plunger 50 is provided with the ball plunger 50. By adjusting the position with respect to the member, it is possible to absorb dimensional errors and the like of the rail portion 32 of the movable member 30, the sliding member 40, and the ball plunger 50. Therefore, the operation load of the movable member 30 can be easily set to a desired load as compared with the conventional case. Moreover, the operation load of the movable member 30 can be adjusted for each product.
