A first slider 451 and a fifth-speed driving gear 425 are arranged along an axial direction on a driving shaft 41. The first slider 451 has a plurality of fifth-speed dog projections 465. A shift fork having an end located in a guide groove 481 of a shift drum 48, and another end connected to the first slider 451. The fifth-speed driving gear 425 has a plurality of fifth-speed dog recesses 475. In gear-shift to a fifth speed, the first slider 451 moves in the axial direction on the driving shaft so that the plurality of fifth-speed dog projections 465 and the plurality of fifth-speed dog recesses 475 mesh with each other. At least four of the plurality of fifth-speed dog projections 465 and at least four of the plurality of fifth-speed dog recesses 475 mesh with each other within a range of 90 degrees at one side in the circumferential direction of the fifth-speed driving gear 425 and a range of 90 degrees at another side in the circumferential direction of the fifth-speed driving gear 425 with respect to a line connecting a meshing point M between the fifth-speed driving gear 425 and the fifth-speed driven gear 445 and a shaft center P of the driving shaft.

There is provided a clutch release bearing in which a water resistance is enhanced. At that side axially opposite from one side where an outer ring rib 22 of a clutch release bearing 10 is formed, there is provided a first seal member 40 externally fitted to an outer ring 20 to be fixed thereto. A seal lip 44 disposed in sliding contact with an outside-diameter surface 32 of an inner ring 30 is formed at a radially-inward distal end of the first seal member 40. An annular guide 50 is provided at a bearing-outward side of the first seal member 40, and an axial lip 46 which extends toward the outside of the bearing and extends to be disposed radially outwardly of the guide 50 is formed at a bearing-outward side face of the first seal member 40. The axial lip 46 is disposed in non-contact, close relation to the guide 50 to form a labyrinth. A radially outwardly-open groove 47 is formed in a joint portion of the axial lip 46 joined to the first seal member 40.

The clutch bearing device comprises a bearing 10 provided with an inner ring 16 and with an outer ring 18, and an operating element 14 mounted into a bore of the bearing and secured to one of the rings. The operating element 14 is provided with a rear plate 26 comprising a flange 26a and at least one centring lug 26c extending axially from said flange on the side opposite to the bearing. The rear plate 26 further comprises at least one stiffener disposed between the flange 26a and the centring lug 26c.

A synchronization device for a manual transmission has a sliding sleeve (112), which has an inner toothing with a plurality of sliding sleeve teeth (118), and a coupling body of a gear wheel, which has an outer toothing with a plurality of coupling body teeth (120), into which the inner toothing of the sliding sleeve (112) can engage. The invention relates to a synchronization unit which is designed to block an axial movement of the sliding sleeve (112), the coupling body teeth (120) having no oblique meshing portion at the axial tooth end (130) close to the sliding sleeve teeth (118). During shifting, the rotational speed of the sliding sleeve (112) and that of the coupling body are adjusted to each other. An axial force (F) of the sliding sleeve against the coupling body builds up and a rotational speed difference between the sliding sleeve (112) and the coupling body is produced so that the end faces (136, 134) of the sliding sleeve teeth (118) and of the coupling body teeth (120) glide along each other, and the sliding sleeve teeth (118) eventually mesh with the coupling body teeth (120).

An operation mechanism for a double-action clutch assembly is provided. The double-action clutch assembly comprises a first clutch (1) having a first clutch bearing(l l), and a second clutch (2) having a second bearing (21). The operation mechanism comprises: a supporting member (33); a first operation member (31) adapted to rotatably couple with the supporting member (33) and to act onto the first clutch bearing (11); and a second operation member (32) adapted to rotatably couple with the supporting member (33) and to act onto the second clutch bearing (21). The second operation member (32) is always spaced a predetermined distance from the first operation member (31) in an operation direction.
