ABSTRACT:
A power transmission apparatus comprises a device for transmitting power by frictional force between first and second rotary members rotated relative to each other; a device for pressing the power transmitting device in a direction of increasing frictional force; a drive device for driving the pressing device in the direction of increasing frictional force; and a stopper for restricting the movement of the drive device.
A differential apparatus comprises a differential casing rotatably supported by a differential carrier through a bearing, and having a differential mechanism; a device for restricting the differential of the differential mechanism by frictional force, the restricting device being disposed within the differential casing; a device for pressing the restricting device to control the frictional force in the differential mechanism; a drive device for actuating the pressing device; and a stopper for restricting the movement of the drive device, the stopper being disposed externally on the differential casing.
