ABSTRACT:
The one-way clutch mechanism of a torque converter which has a short axial dimension, and which neither produces a shock noise (an abnormal sound) nor suffers a power loss in the idle mode thereof. An outer race (30 in FIG. 1 ) is united with a stator (18), and supports the stator (18) so as to be axially movable and rotatable with respect to a stationary shaft (16). The outer race (30) includes a first side face (32) which is formed with first teeth. An inner race (40) is united with the stationary shaft (16), and includes a second side face (42) opposite to the first side face (32). The second side face (42) is formed with second teeth which can prohibit the rotation of the outer race (30) in one direction, by meshing with the first teeth. The stator (18) and the outer race (30) receive the axial component force of a fluid stream which changes depending upon a speed ratio. Thus, the unitary structure (18, 30) comes near to or away from the inner race (40), thereby to engage or disengage the first teeth and the second teeth.
