Abstract
A light weight saber saw with reduced numbers of mechanical components and capable of preventing liquid and dust from entering interior of a housing. A plunger reciprocates only in its axial direction in conformity with a longitudinal direction of the housing. A blade holding portion is pivotally movably connected to a front end of the plunger. The blade holding portion includes a plunger chip through which a rear end of a blade is insertable, and a blade holder covering the plunger chip. The blade holder has a track side corresponding to tooth side of the blade, and a track having an inclined track surface is provided at the track side. The housing rotatably supports a roller in rolling contact with the track surface. When the blade is retractingly moved into the housing, the blade holding portion and the blade are pivotally moved totether toward a workpiece by the contact between the roller and the track surface.
