The motor (21) has a drive shaft (22). 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) defines 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 includes a first motion conversion (51A,52,52B) mechanism and a second motion conversion mechanism (51B, 53, 53B). The piston (54) is connected to the first motion conversion mechanism (51A,52,52B) and is capable of moving in a reciprocating motion in directions substantially parallel to the axial direction of the intermediate shaft (41). The counterweight is connected to the second motion conversion mechanism (51B,53,53B) and is capable of reciprocating in directions substantially parallel to the axial direction of the intermediate shaft (41) in opposite phase to the reciprocating motion of the piston (54).
