Befestigung eines Hauptzylinders eines Fahrzeugs

摘要

An attachment structure for a vehicle master cylinder (14) suppresses displacement of a pedal (1) towards the rear of the vehicle to make it possible to maintain large legroom in front of the driver's seat. A clutch pedal (1) is fitted to a dashboard (3) via a pedal bracket (5). The master cylinder (14) is attached to the side surface sections (9) of the pedal bracket by a fastening member (55) at a flange section (53) so as to be capable of swinging around a fixed axis extending in the widthwise direction of the vehicle. The master cylinder (14) and the clutch pedal (1) are mechanically connected through a push rod (23). If an external force greater than a specified value is input, the master cylinder (14) swings around a fixed axis extending in the widthwise direction of the vehicle body. The push rod (23) also swings with its pivot shaft (43) as a fulcrum, accompanying swinging of the master cylinder (14). Displacement of the master cylinder (14) and the push rod (23) towards the rear of the vehicle is controlled by the swinging itself.
