PROBLEM TO BE SOLVED: To block transmission of torque to an output side so that a lock is removed while an input side of a one-way clutch unit is positively turned; and to increase allowable torque. SOLUTION: The one-way clutch unit is provided with a one-way clutch 2 sandwiching a plurality of rolling bodies 15 at two places of pockets 8 which are formed between an inner ring 6 and outer ring 7 and have a wedge angleθ, an annular section, in which the unlocking member 3 is coaxial with the inner ring 6, assembled with a lock releasing member 3, and unlocking pieces 18 axially projected to the circular section in response to respective pockets 8. The unlocking pieces 18 are inserted between an end section opposing to a narrow side of the wedge angleθof the respective pockets 8 and the rolling bodies 15, and the individual rolling bodies 15 are moved to an expansion direction of the wedge angleθin order to unlock the lock so that the unlocking member 3 is operated from the outside.
