摘要： An effective technique is provided for rationally clamping and holding various kinds of tool bits which can be selectively replaced with each other and attached to the driving shaft, in a power toolThe power tool includes a driving shaft 125 for driving a tool bit 109A or 109B which is arbitrarily selected from various kinds of tool bits, a first clamping element 133 provided on the driving shaft 125 and a second clamping element 135A, 135B provided separately from the driving shaft 125 and can be fixed to the driving shaft 125. The selected tool bit 109A, 109B is clamped and held between the first clamping element 133 and the second clamping element 135A, 135B. Various kinds of the tool bits 109A, 109B have holes 163, 167 formed according to the kind of the tool bit, and either one of the first clamping element 133 and the second clamping element 135A, 135B has various kinds of protruding engagement parts 149, 153 appropriate to the kind of the tool bit 109A, 109B and engaged with the holes 163, 167 formed according to the kind of the tool bit 109A, 109B.
