PURPOSE:To uniformly lubricate the space between the bearing hole of a clevis bush fixed to a clutch pedal and a coupling pin inserted through the bearing hole throughout the periphery and to obtain the most excellent lubricating action in accordance with the relative turning angle of them. CONSTITUTION:A bearing hole 26 of a clevis bush 24 is formed into a regular polygon circumscribed to a coupling pin 22, and gaps between the bearing hole 26 and the coupling pin 22 formed in apex parts are used as oil basin and a number (n) of apexes of this regular polygon is set to a minimum natural number which satisfies the formula n>=360/A based on A where A is the angle of shake of a clutch pedal 12. |
