  • Drive force transmission device
    Patent number: 9222524
    Abstract: A drive force transmission device includes a clutch operatively interposed between a hub member and a drum member to selectively transmit drive power therebetween. A first rotating shaft member is coupled to the hub member to rotate with the hub member. A second rotating shaft member is coupled to a separating wall part of the drum member to rotate with the drum member. A support member rotatably supports the second rotating shaft member via a bearing. The support member includes a restriction part that restricts axial movement of an outer race of the bearing. A bottom portion of the separating wall part is a radially offset towards the bearing space with respect to a top portion of the separating wall so that the bottom portion radial overlaps with the restriction part as viewed perpendicular to a rotational axis of the drum member.
