Claims (1)

[Claims for Utility Model Registration] (1) A shock absorber body, a damping force adjustment member that adjusts the opening degree of the damping force generation mechanism of the shock absorber body, and a damping force adjustment member that is connected to the damping force adjustment member to perform the adjustment operation. a drive device having a drive source and an encoder plate that controls the operation and stop of the drive source by controlling the stop position by conducting and discontinuing the operation and stopping of the drive source with a power supply circuit described later; A first switch for selection is connected to a power source, and includes a power supply circuit that selectively supplies driving power to a drive device in order to control the opening position to the selected opening position, and the drive device has a damping force adjusting member for adjusting the damping force adjustment member. A damping force adjustment device for a shock absorber, characterized in that a second switch element that operates in conjunction with the first switch forming a braking circuit for the drive source is connected via the encoder plate when the operation is completed. . (2) The shock absorber damping force adjusting device according to claim 1, wherein a display circuit indicating the selected adjustment position is connected to the power supply circuit. (3) The shock according to claim 1 or 2, wherein the encoder plate is formed to constitute a circuit for controlling the damping force adjusting member to a selected position and a braking circuit for the drive source. Absorber damping force adjustment device. (4) The encoder plate is made of an annular conductive disk, and has a concave portion on the outer periphery in which the circuit that controls the selected position is non-conductive when selecting the damping force, and a concave portion on the inner periphery in which the circuit that controls the selected position is non-conductive. A damping force adjusting device for a shock absorber according to claim 1 or 2, which has a convex portion through which a braking circuit for braking a drive source is electrically conductive. (5) The encoder plate selects one brush on the outer circumference of two concentric circumferences connecting a plurality of brushes in contact with the encoder plate, and the encoder plate and the brushes are non-conductive. A utility model registration claim having one notch such that when the one brush is selected on the inner circumference, only the inner brush corresponding to the one brush is electrically connected to the encoder plate. A damping force adjustment device for a shock absorber according to the first item.
