Claims

[Claims for Utility Model Registration] (1) A sleeve fitted onto the outer peripheral surface of the shaft so as to be able to slide freely in the axial direction, an outward flange-shaped support plate fixed to the outer peripheral surface of the sleeve, an outer ring, Inner circle,
and a plurality of rolling elements provided between the inner and outer rings, one end surface of the outer ring is slidably abutted on one side of the support plate, and a part of the inner ring is placed on the opposite side of the support plate than the outer ring. It consists of a protruding release bearing, an elastic member abutted against the other end surface of the outer ring, and a case for connecting and holding the outer ring and the elastic member to a support plate. The end of the cylindrical part having an inner diameter larger than the outer diameter of the elastic member is bent inward to form a restraining part in the form of an inward flange, and the other end of the cylindrical part is attached to the other end of the case. A plurality of tongue-shaped portions are intermittently formed to protrude further in the axial direction than the supporting plate, and a recessed portion that engages with the tongue-shaped portion is formed at a position aligned with the tongue-shaped portion on the outer peripheral edge of the support plate. At the same time, with the concave portion and the tongue-shaped portion engaged with each other, each of the tongue-shaped portions is bent inward to form a plurality of locking pieces, and the outer peripheral edge of the support plate is attached to the case. By sandwiching the case between the other end edge and the locking piece to support the case on the outer peripheral edge of the support plate, and sandwiching the outer ring and the elastic member between the support plate and the restraining part. , a clutch release bearing unit in which an outer ring and an elastic member are connected and held by a support plate. (2) The part of the other end of the cylindrical part that is detached from the plurality of locking pieces is bent outward at a right angle to form a bending receiving part, and this bending receiving part and each locking piece are used to secure the support plate. 2. The clutch release bearing unit according to claim 1, wherein the clutch release bearing unit holds the outer peripheral edge of the clutch release. (3) The outer ring and the elastic member are bonded and held to the support plate by overlapping the support plate and anvil, and bringing the support plate into contact with the other end of the cylindrical portion and the anvil with a plurality of locking pieces. 3. The clutch release bearing unit according to claim 1, wherein the support plate and anvil are combined.
