Abstract
Provided is a damper capable of damping a moving member which reciprocates along an axis, using a damping force having a hysteresis property. A damper includes a cylindrical housing into which a push rod is to be inserted in the direction of an axis thereof, and a damping mechanism placed in the housing and capable of damping the push rod by a damping force having a hysteresis property, wherein the damper is to be attached using a master cylinder mount space of a clutch pedal unit. In the damping mechanism of the damper, engagement between a helical cam groove formed in an inner wall of the housing and a guide protrusion formed on an outer circumference of a rotatable friction disk causes reciprocating linear motion of the push rod to be converted into rotating motion of the rotatable friction disk, and other friction disks, placed on both sides of the rotatable friction disk are pressed against respective sliding surfaces, of the rotating friction disk by an elastic force of a coil spring depending on an amount of displacement of the push rod.
