• a swinging member configured to be caused to swing by rotation of the rotary shaft member,
• a tool accessory driving mechanism configured to drive the tool accessory by swinging of the swinging member,
• a body housing the driving motor, the rotary shaft member, the swinging member and the tool accessory driving mechanism, and
• a vibration reducing mechanism configured to reduce vibration caused in the body, wherein:
• the vibration reducing mechanism includes:
• a dynamic vibration reducer having an elastic member and a weight, the weight being biased by the elastic member and being reciprocatable;
• and
• a connecting member connecting the weight and the swinging member, and
• the vibration reducing mechanism is configured to reciprocate the weight via the connecting member by the swinging of the swinging member.
