Claims

[Scope of utility model registration request]

A lever plate is fixed to the inner periphery of the diaphragm spring, and the inner race of the release bearing has a cylindrical extension extending axially to the radially inward side of the lever plate, and between the cylindrical extension and the lever plate. In a pull type clutch cover assembly, a wedge collar is disposed at the cylindrical extension, and the clutch is disconnected by moving the release bearing along the axial direction to a side opposite to the diaphragm spring side. a cylindrical annular portion that slidably fits on the outer periphery of the annular portion, a number of tongue portions protruding in the axial direction from an edge of the annular portion opposite to the clutch closing direction; a plurality of protrusions projecting outward in the radial direction from the edge of the direction; each of the tongues includes a bent portion whose inner circumferential surface becomes convex as it faces inward in the radial direction; an inner circumferential surface of the portion forms a fitting portion that fits into the cylindrical extension portion so as not to be movable in the axial direction;
The outer circumferential surface of the bent portion forms an engaging portion that engages with the lever plate in the axial direction and in the clutch release direction, and the cylindrical extension portion is formed on the release bearing side surface of the plurality of protrusions. By fixing a ring-shaped reinforcing member that loosely fits around the outer periphery of the wedge collar and moving the wedge collar in a direction opposite to the clutch closing direction with respect to the lever plate, the fitting part is separated from the cylindrical extension part. the tongue is allowed to deform radially outward to a disengaged position;
by removing the tubular extension from the tongue;
A wedge collar for a pull-type clutch cover assembly, characterized in that the tongue portion is allowed to deform radially inward to a position where it does not engage with the lever plate in the axial direction.
