PROBLEM TO BE SOLVED: To provide an impact tool such as an electric hammer capable of suppressing reduction in a vibration-reducing function. ! SOLUTION: An electric hammer 10 includes: a piston 21 and a striking piece 28 which are linearly moved to generate striking force; a weight 37 which is set movably along a movement direction of the piston 21 and the striking piece 28 and reduces vibration; a motor housing 14 which supports coil springs 38a 38b set on both sides of the weight 37 in the movement direction, the piston 21 and the striking piece 28, and supports the weight 37 via the coil springs 38a, 38b; and a plurality of links 44a, 44b one end of each of which is connected to the motor housing 14 and the other end of each of which is connected to the weight 37 to restrict the weight 37 from moving in a direction intersecting to a center line C. !
