It is an object of the invention to provide a reciprocating power tool (101) having a power transmitting mechanism (131) for converting a rotating output of a driving motor (121) into linear motion in the axial direction of the tool bit (113). The power transmitting mechanism includes an internal gear (175), a plancrary gear (181), a power transmitting part (183,159), a rotation preventing mechanism (185) and an internal gear rotation lock (189). Further, an internal gear rotation lock (189) prevents the internal gear (175) from rotating in a direction opposite to said predetermined direction. Therefore, the internal gear (175) may be rotated only in one direction via the internal gear rotation lock (185,189) and as a result, the internal gear (175) can be reliably locked in a predetermined position without causing rattling. Thus, the accuracy of the locked position of the internal gear (175) can be enhanced and stable operation can be realized. |
