ABSTRACT:
A shock absorber comprising a device for detecting the position and velocity of a moving object; a movement mechanism including a movable part, means for detecting the contact between the movable part and the object, and means for detecting the displacement value of the movable part; and a device for controlling the movement mechanism. With information from the position and velocity detecting device, the control device controls the movement mechanism so that the movable part may move on the course of the object and in the same direction as the moving direction thereof at a velocity corresponding to the velocity of the object. Subsequently, with an information from the contact detecting means, it reduces the velocity of the movable part on the basis of a predetermined deceleration pattern when the object has come into contact with the movable part. Further, with an information from the displacement value detecting means, it executes a positioning control so as to stop the movable part at a predetermined position when the displacement value of the movable part has reached a predetermined value.
