A one-way clutch including: a driving force input member; a driving force output member; and a driving force transmitting member, wherein, when the driving force input member performs forward rotation, the second engaging part performs forward rotation in a state of being engaged with the first engaging part, so as to connect the first ratchet engaging part and the second ratchet engaging part, in order to make the driving force output member perform forward rotation, wherein, when the driving force input member performs reverse rotation, the second engaging part performs reverse rotation in a state of being engaged with the first engaging part, so as to make the driving force transmitting member and the first ratchet engaging part perform reverse rotation so that the first ratchet engaging part is separated from the second ratchet engaging part, in order not to make the driving force output member perform reverse rotation.

A clutch structure that includes a motor to directly drive a rotary disc of an actuation unit, and the actuation unit further directly act on a push unit, so as to achieve reduction of size. Further, the push unit has a spring holder that drives a push bracket to press against a clutching unit, and the push bracket and the clutching unit are rotatably in synchronization with each other and a group of balls is arranged between the push bracket and the spring holder, such that smooth rotation can be maintained even during the process of pressing to thereby effectively reduce pause and setback incurring in coupling and connection and also to efficiently establish a transmission clutching force to have the operability not affected by the delay.

A clutch mechanism is used in a rotary power tool having a motor. The clutch mechanism includes an input member to which torque from the motor is transferred and an output member co-rotatable with the input member. The output member defines a rotational axis. A cam surface is formed on one of the input member or the output member. First and second compression springs are carried by the other of the input member or the output member for co-rotation therewith. A follower has a circular cross-sectional shape and is biased against the cam surface by the first and second compression springs. In response to relative rotation between the input member and the output member, the cam surface displaces the follower along a line of action coaxial or parallel with each of the first and second compression springs. The line of action does not intersect the rotational axis.
