Abstract: The handheld power saw includes a drive mechanism with a lifting rod; a saw blade with an elongated recess in a guide region thereof and a retaining region with a T-shaped extension; a coupling device for retaining and driving the saw blade located on the lifting rod, which includes a clamping sleeve configured to receive the T-shaped extension to connect the saw blade to the lifting rod; a guide assembly for guiding oscillatory motion of the saw blade, which includes two lateral bracing devices arranged on opposite sides of the saw blade that shield the coupling device from shear forces; a pressure roller supported on a bolt, which is arranged to bear on an edge of the saw blade and a pressure bolt arranged in the elongated recess to directly guide the saw blade.

Abstract: The invention is based on a handheld power saw, having a coupling means (10) for retaining and driving a saw blade (12), and having a guide assembly (14) for guiding an oscillating motion (16) of the saw blade (12). It is proposed that the guide assembly (14) includes at least one lateral bracing means (18, 18?) for shielding the coupling means (10) from shear forces acting on the saw blade (12).
