Claims

[Scope of utility model registration request]

In a clutch that uses a release lever connected to the clutch pedal to perform a tensile release operation to move the release bearing away from the flywheel, a load-transmitting lever with an inner fulcrum connected to a retainer connected to the release bearing is provided, and this lever A substantially annular adjuster star ring for adjusting facing wear allowance connected to the outer periphery side fulcrum of the clutch cover is screwed onto the inner surface of the clutch cover, and an intermediate fulcrum that fits into the groove of the pressure plate is formed at the middle part of the lever. A notch is formed in the middle part of the clutch in the circumferential direction at the radially outer peripheral end of the lever, and bearing portions extending outward in the clutch's radial direction are formed on both sides of the notch in the clutch's circumferential direction. A shaft extending in the circumferential direction of the clutch is rotatably supported between the parts, a ratchet wheel is fixed to the part where the shaft passes through the notch, and a worm wheel is attached to one of the ends of the shaft outside the bearing part. A rack is formed on the end face of the adjuster star ring facing the pressure plate to which the worm wheel is fixed, and a reversal prevention mechanism for preventing the shaft from reversing is provided at the other end outside the bearing portion of the shaft. A substantially plate-shaped elastic member made of spring steel is provided between the intermediate fulcrum of the lever and the inner fulcrum, the inner end of which is fixed, and the outer end of which is engaged with the ratchet external teeth of the ratchet wheel. , the lever is pressed against the end surface of the elastic member on the side opposite to the pressure plate between the intermediate fulcrum and the inner fulcrum, and the adjuster ring is rotated in the direction approaching the pressure plate by the ratchet wheel and the worm wheel. A substantially plate-shaped pressing member is provided that presses the elastic member so as to move, and the tension stroke of the retainer in an initial state before the clutch disk is worn out is determined between the inner circumferential end of the pressing member and the elastic member. A self-adjuster for a pull-type clutch, characterized in that a pressing member is fixed to the lever with an absorbable play angle and in the initial state, the outer peripheral end is in pressure contact with the elastic member.
