Claims

[Scope of claim for utility model registration] (1) A cylindrical sleeve made of synthetic resin that is fitted onto the outer circumferential surface of the guide shaft so as to be able to slide freely in the axial direction, and a metal fixed to the outer circumferential surface of this sleeve. In a clutch release bearing unit consisting of an outward flange made of a plate and a release bearing held on one side of the outward flange, a side plate made of synthetic resin is fixed to the other side of the outward flange. A bearing unit for a clutch release is characterized in that the assembly width can be freely adjusted by changing the thickness of the side plate. (2) A pair of folding walls parallel to each other is formed at diametrically opposed positions on the outer periphery of the outward flange part and on the outer periphery side of the side plate, and the inner surface of each folding wall and the outer surface of the tip of the release fork are formed. 2. The clutch release bearing unit according to claim 1, wherein rotation about the guide shaft is prevented by engagement with the clutch release bearing unit. (3) A pair of folded walls parallel to each other is formed at the diametrical position of the outer periphery of the side plate, and the inner surface of each folded wall and the outer surface of the tip of the release fork are engaged to form a pair of folded walls around the guide shaft. 2. A bearing unit for a clutch release according to claim 1, wherein the clutch release is prevented from rotating. (4) A cylindrical portion is formed on the inner peripheral edge of the side plate facing opposite to the release bearing held by the outward flange portion, and a cylindrical portion is formed on the outer periphery of this cylindrical portion at a position diametrically opposed to the inner surface of the tip of the release fork. 2. The clutch release bearing unit according to claim 1, wherein rotation about the guide shaft is prevented by forming a pair of mutually parallel flat surfaces that engage with the clutch release. (5) The outward flange portion and the side plate can be connected by bending tongue pieces, which are formed at multiple locations on the outer circumferential edge of the outward flange portion and projecting from the outer circumferential edge of the side plate, toward the outer circumferential edge of the side plate. 5. A bearing unit for a clutch release according to claim 1, wherein the clutch release bearing unit is fixedly connected. (6) At multiple locations on the surface of the side plate facing the outward flange section, locking pieces whose thickness can be elastically contracted are installed at multiple locations on the outward flange section at locations facing each locking piece. Each stop piece forms a through hole through which it can freely pass while elastically reducing its thickness, and
5. A bearing unit for a clutch release according to claim 1, wherein the outward flange portion and the side plate are coupled and fixed by engaging the locking piece with the through hole.
