Problems to be Solved by the Invention In the case of the self-aligning type clutch release bearing device as described above, the rigid sleeve (1) is mounted before assembling this device to the automobile.
The release bearing (3) is assembled into the one in which the elastic sleeve (2) is fixed, but the release bearing (3) is only fixed by the retaining projection (2a) of the elastic sleeve (2). Therefore, if the release bearing (3) is pulled to the left at the time of transportation or assembly, the release bearing (3) comes out relatively easily, and these are separated. To assemble the separated release bearing (3) into the elastic sleeve (2), the elastic sleeve (2) is inserted into the inner ring (4) from the right side, and the retaining projection (2a) is deformed and fitted. At this time, the retaining protrusion (2
Since a) is hidden inside the outer ring (5), it is very difficult to assemble.

Means for Solving the Problems In a self-centering clutch release bearing device according to the present invention, a self-aligning elastic sleeve is fixed to the outer circumference of a rigid sleeve, and an inner ring of the clutch release bearing is fixed to the outer circumference of the elastic sleeve. In a self-aligning clutch release bearing device in which the outer ring of the clutch release bearing rotates to come into contact with the diaphragm spring, in the clutch release bearing, the outer ring end of the outer ring of the clutch release bearing enters the inner end of the inner ring. A stopper cylindrical portion is formed, a lip portion that is in contact with the outer ring is formed at the end of the elastic sleeve on the diaphragm spring side, and a retaining protrusion that extends outward from the inner peripheral edge of the end of the inner ring is formed at this lip portion. The gap between the inner peripheral surface of the end of the inner ring and the outer peripheral surface of the retaining ring of the outer ring is the axis of the retaining protrusion. And it is characterized in that is smaller than the total thickness of the thickness and the lip portion of the direction.

Action When a force is applied to the elastic sleeve and the release bearing in the direction in which they come off, the retaining projection of the elastic sleeve collapses, and the elastic sleeve and release bearing come out of the gap between the inner peripheral surface of the end of the inner ring and the outer peripheral surface of the retaining cylinder of the outer ring. However, the retaining protrusion together with the lip forms a thickness larger than the gap, and the retaining protrusion does not come off from the gap, preventing the elastic sleeve and the inner ring from coming off. . Further, since the lip portion of the elastic sleeve is in contact with the outer ring, the sealing of this portion is reliable.

An inner peripheral edge portion of the diaphragm spring receiving portion (5a) of the outer ring (5) of the release bearing (3) is integrally formed with a retaining cylindrical portion (5b) which is inserted inside the left end portion of the inner ring (4). The left end of the elastic sleeve (2) is integrally formed with a lip portion (2c) that extends obliquely outward to the left, and the lip portion (2c) is integrally formed with a retaining projection (2a). The lip portion (2c) of the elastic sleeve (2) is in contact with the inner surface of the diaphragm spring receiving portion (5a) of the outer ring (5) to ensure the sealing of this portion. Also, the second
As shown in the enlarged view of the figure, the gap (A) between the inner peripheral surface of the end portion of the inner ring (4) and the outer peripheral surface of the retaining ring cylindrical portion (5b) of the outer ring (5) forms a retaining protrusion (2a). Is smaller than the total (B + C) of the axial thickness (B) and the lip portion (2c) thickness (C).

When a leftward force is applied to the release bearing (3) in the direction of coming out of the elastic sleeve (2), the retaining projection (2a) of the elastic sleeve (2) falls to the left side and tries to come off from the end of the inner ring (4). However, since there is a retaining cylindrical portion (5b) of the outer ring (5) inside, the retaining protrusion (2a) of the elastic sleeve (2) contacts the lip portion (2c), and the lip portion (2c)
The inner peripheral surface of c) contacts the outer peripheral surface of the retaining cylindrical portion (5b). The clearance (A) between the inner peripheral surface of the end portion of the inner ring (4) and the outer peripheral surface of the retaining cylindrical portion (5b) forms a retaining protrusion (2a).
Axial thickness (B) and lip portion (2c) thickness (C)
Since it is smaller than the total of (B + C), the retaining protrusion (2a)
Does not come off from the inner ring (4), and the elastic sleeve (2) and the inner ring (4) are prevented from coming off.
