PROBLEM TO BE SOLVED: To provide a power tool capable of effectively reducing vibration generated by the drive of a stroking element without causing enlargement and the deterioration of work efficiency at low cost. SOLUTION: A weight supporting member 73 has a first connecting part 73B, a second connecting part 73C and an elastic deforming part 73D for connecting the first connecting part 73B to the second connecting part 73C. The elastic deforming part 73D has first and second elastic deforming parts 73D1, 73D2 and a weight mounting part 73D3. Cutouts 73f, 73g are formed on the first and the second elastic deforming parts 73D1, 73D2, respectively. The first and the second elastic deforming parts 73D1, 73D2 have shapes with widths gradually changed by the cutouts 73f, 73g. Consequently, the first and the second elastic deforming parts 73D1, 73D2 have cross-sectional areas smaller than a cross-sectional area of the first connecting part 73B, a cross-sectional area of the second connecting part 73C and a cross-sectional area of the weight mounting part 73D3.
