Electrical power tool

Abstract

An electrical power tool (1) includes a motor (21), a casing (2), a piston (54), an intermediate shaft (41), a motion conversion mechanism (51A, 52, 52B; 51B, 53, 53B), and a plurality of types of anti-vibration mechanism (31,32,33; 55,40b). The motor (21) has a drive shaft (22). The casing (2) accommodates at least the motor (21). The piston (54) is driven by a rotary motion of the drive shaft (22). The intermediate shaft (41) extends parallel to the drive shaft (22) and is driven to rotate by the rotary motion of the drive shaft (22), the intermediate shaft (41) defining an axial direction. The motion conversion mechanism (51A, 52, 52B; 51B, 53, 53B) is disposed on the intermediate shaft (41) and is capable of moving in association with the intermediate shaft (41) for converting the rotary motion of the drive shaft (22) to a reciprocating motion. The motion conversion mechanism (51A, 52, 52B; 51B, 53, 53B) includes a first motion conversion mechanism (51A,52,52B) that is connected to the piston (54) and moves the piston in a reciprocating motion in directions substantially parallel to the axial direction of the intermediate shaft (41). The plurality of types of anti-vibration mechanism (31,32,33; 55,40b) is accommodated in the casing.
