Abstract
A power tool includes a striking cylinder, a striking piston slidably housed in the striking cylinder, a driver coupled to a bottom surface of the striking piston, and a cushioning mechanism configured to absorb an impact of striking a fastener with the driver when the striking piston is driven. The cushioning mechanism includes a housing formed below the striking cylinder, and a bumper housed in the housing to receive the bottom surface of the striking piston. The bumper is formed in a tubular shape, a wall thickness of a central section of the bumper is greater than wall thicknesses of an upper section and a lower section of the bumper, and the wall thicknesses of the upper section and the lower section are substantially the same.
