发明名称 Impact tool
摘要 An impact tool comprising a motor, a hammer (8) that is rotated and axially moved by a drive force of the motor, an anvil (3) that repeats engagement/disengagement from the hammer (8) accompanying rotation and axial movements of the hammer (8), and a tip tool (4) mounted to the anvil (3), the anvil (3) comprising a first split piece (3A), which includes pawls (3c) (first concave-convex part) on an opposite side to the hammer and repeats engagement/disengagement from the hammer (8), a second split piece (3B), which includes pawls (3f) (second concave-convex part) engageable with the pawls (first concave-convex part) (3c) of the first split piece (3A) in a direction of rotation, and to which the tip tool (4) is mounted, and a rubber damper (elastic body) (13) interposed between the first and second split pieces (3A), (3B) to prevent direct contact between the pawls (first concave-convex part) (3c) and the pawls (second concave-convex part) (3f) in the direction of rotation and in an axial direction.
