ヨツクアブソーバ。[Claims for Utility Model Registration] (1) A piston slidably provided in the cylinder defines the inside of the cylinder into an upper piston chamber and a lower piston chamber, and The piston upper chamber and the piston lower chamber are connected to each other, and a rotary shaft inserted into the piston rod is rotated by an actuator, and the rotation of the rotary shaft causes a shutter body provided at one end of the rotary shaft to disconnect the communication passage. In the damping force adjustable shock absorber that adjusts the damping force by changing the area, one of a pattern and a brush constituting a damping force adjustment switch that stops the actuator at a predetermined position is placed on the rotating shaft, and the other is placed on the rotating shaft. A damping force adjustable shock absorber, characterized in that the damping force adjustable shock absorber is provided on a fixed member, and the pattern and the brush are brought into contact with each other from the radial direction of the rotating shaft. (2) The switch is connected to a current-carrying body that rotates in accordance with the rotation of the rotating shaft, and when the current-carrying body is at a predetermined stop position, the switch de-energizes the actuator. , by switching a changeover switch, the actuator is energized, and when the energizing body rotates to a predetermined position, the energization of the actuator is cut off, and a counter electromotive force is applied to the actuator to stop the actuator. The damping force adjustable shock absorber according to claim 1, characterized in that the damping force adjustable shock absorber is included in an actuator control circuit for controlling the damping force.
