Abstract: A rotatable rear hand grip (3) is releasably locked at a desired rotational position by operation of a control lever member (4). The power hand tool includes: a tool body (1) including an engine for generating driving power used for performing work; a front hand grip (2) fixed to the tool body; a rear hand grip including: a control lever member coupled to the engine for controlling an output of the engine; a supporting mechanism for supporting the rear hand grip rotationally about an axis (AX) between the tool body and the rear hand grip; a locking mechanism for locking the rear hand grip at one rotational position about the axis in response to the control lever member; and a controlling mechanism (4d) for allowing the control lever member to control the output of the engine after the locking mechanism locks the rear hand grip.
