And the axial end faces of the plurality of rollers 7 are close to each other. Therefore, when assembling the transmission, even if the inside of the cylindrical roller bearing 4 is inserted while the rotating shaft 1 is inclined, the sealing material on the end face 1a of the rotating shaft 1 and the outlet side (the right side in FIG. 1). The inner peripheral edge portion of the rubber material 11 constituting the rubber member 8 is less likely to collide with the inner peripheral edge portion of the rubber member 11, and the seal member 8 is less likely to be damaged.

１１を傷める可能性を極く少なくする事が出来る。That is, in the case of the cylindrical roller bearing 4 incorporated in the supporting device for a rotating shaft of an automobile transmission according to the present invention, the distance 1 between the inner peripheral edge 7 of the rubber material 11 and the end face is incorporated in the conventional device. For example, a cylindrical roller bearing 4 as shown in FIG.
Is sufficiently smaller than the distance L in the case of (1 <L).
For this reason, even if the rotating shaft 1 inserted through the inside of the plurality of rollers 7 is slightly inclined, the chamfered portion 15 formed on the outer peripheral edge of the rotating shaft 1 at the tip end in the insertion direction is disengaged from the inner peripheral edge of the rubber material 11, and The end surface 1a of the shaft 1 does not hit the inner peripheral edge of the rubber material 11. For this reason, the rubber member 11 constituting the seal member 8 can be damaged by the large-diameter flange-shaped gear 2 fixed to the intermediate portion of the rotating shaft 1 even if the portion where the rotating shaft 1 is inserted is not visible. Sex can be extremely reduced.
