Pedalvorrichtung mit Reibungsdämpfer, für Fahrzeug

摘要

A friction damper includes: a hollow cylindrical member (22) with a bottom (25); a movable member (23) disposed in said hollow cylindrical member in such a manner as to be movable in an axial direction of said hollow cylindrical member but immovable about an axis of said hollow cylindrical member; a coil spring (27) disposed between said movable member and the bottom of said hollow cylindrical member, one end (24) of said coil spring abutting against the bottom of said hollow cylindrical member and another end (26) thereof abutting against said movable member; a rotating member (28) disposed in said hollow cylindrical member in such a manner as to oppose said movable member and to be relatively rotatable about the axis of said hollow cylindrical member; and a frictionally-resisting-force generating mechanism (29) for generating a frictionally resisting force to the relative rotation of said rotating member with respect to said hollow cylindrical member, and for causing said movable member to move away from said rotating member in the axial direction against the resiliency of said coil spring and to approach the bottom of said hollow cylindrical member so as to increase the spring force of said coil spring, thereby increasing the frictionally resisting force.
