Title:
DAMPER AND OPERATING UNIT
Document Type and Number:
WIPO Patent Application WO/2019/039377
Kind Code:
A1
Abstract:
Provided is a damper capable of braking a moving member which reciprocates along an axis, using a braking force having a hysteresis characteristic. A damper (100) includes a cylindrical housing (2) into which a push rod (8) is inserted in the direction of an axis (O) thereof, and a braking mechanism which is accommodated in the housing (2) and which brakes the push rod (8) using a braking force having a hysteresis characteristic, wherein the damper is attached using a master cylinder attachment space of a clutch pedal unit. In the braking mechanism of the damper (100), engagement between a helical cam groove formed in an inner wall of the housing (2) and a guide protrusion (63) formed on an outer circumference (62) of a rotating friction disk (6) causes reciprocating linear motion of the push rod (8) to be converted into rotating motion of the rotating friction disk (6), and other friction disks (5), (7) disposed on either side of the rotating friction disk (6) are pressed against sliding surfaces (60), (61) of the rotating friction disk (6) by an elastic force of a coil spring (4) corresponding to an amount of displacement of the push rod (8).
