ロソー。 The rotary motion is driven by an electric motor or an air motor equipped with a cooling fan and is decelerated by a reduction gear in a gear case, using a crank mechanism.
In a reciprocating saw that replaces the reciprocating motion of a plunger and cuts pipes, etc. with a saw blade that is attached to the tip of the plunger and protrudes from the tip of the gear case and moves reciprocally, a small hole that communicates with the center hole of the plunger is used. Several pieces are provided in the radial direction at the base of the saw blade attachment part at the tip of the plunger, and cooling air from the cooling fan or exhaust air from the air motor is guided to the rear end hole of the plunger. Reciprocating saw with dust prevention device.
