ACCELERATOR PEDAL MECHANISM FOR VEHICLE

摘要

A pedal rod (12) connected to an accelerator pedal (10) has one end which is a free end. A friction generating device (20) is disposed at the free end of the pedal rod (12). The friction generating device (20) has a cylindrical housing (26) as a fixed friction member, a movable friction member (28) disposed movably in the interior of the housing (26) and kept in contact with the housing, and a friction member return spring (30) for urging the movable friction member (28) in a predetermined direction. When the accelerator pedal (10) is depressed, the free end of the pedal rod (12) pushes both movable friction member (28) and friction member return spring (30), so that there occur friction between the movable friction member (28) and the housing (fixed friction member) and friction induced by the friction member return spring (30). Upon release of the accelerator pedal (10), the movable friction member (28) is returned to its original position by the friction member return spring (30).
