Abstract
An impact tool includes a casing (13) supporting a tip tool (12), a piston (41) provided in the casing (13), an electric motor (11) provided in the casing (13), a motion converting mechanism (45) provided in the casing (13), and a vibration reducing mechanism (47) provided in the casing (13). The vibration reducing mechanism (47) has a supporting member, which is swingable with using a fixing position (J) as a supporting point and a weight (49) attached to a free end side of the supporting member. In a plane including a center line (C), the gravity center (H) of the weight (49) and the gravity center (G) of the casing (13) are disposed at mutually different locations, and the fixing position (J) is disposed on the side of the gravity center (G) relative to the center line (C).
