    摘要： A bumper of a driving tool has a cylindrical overall shape and also has a space portion expanding downward therein. The bumper is provided with an upper portion, an intermediate portion, and a lower portion. A normal inclined-surface, in which an outer diameter becomes larger from an upper end of a full height of the bumper toward a slightly upper position of the intermediate portion, is formed at a periphery of the upper portion. A bulging-out portion haying the largest outer diameter in the bumper is bulged out, at a periphery of the intermediate portion. A reverse inclined-surface, in which the outer diameter becomes smaller toward downward, is formed at the periphery of the lower portion.

    摘要： A fastening pin has an enlarged head part, and a shaft part. The shaft part includes a large diameter section formed below the enlarged head part, a middle shaft section formed below the large diameter section, and a small diameter section extending from the middle shaft section to a leading end of the fastening pin. The large diameter section includes a round portion formed below the enlarged head part and a taper portion formed between the round portion and the middle shaft section. A diameter of the large diameter section at a side of the enlarged head part is larger than a diameter of the large diameter section at a side of the middle shaft section. The middle shaft section has a uniform diameter from a side of the large diameter section to a side of the small diameter section.

    摘要： 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.

    摘要： An air intake valve seat 24 is formed by mounting a cylinder seal 29 of rubber or the like from an upper face of a ring-shaped flange portion 28 formed to project from an outer peripheral face of a strike cylinder 15 over to an upper end portion of the strike cylinder 15 to cover surfaces thereof. A main valve 21 in a ring shape is arranged along an outer periphery of the strike cylinder 15 on an upper side of a ring-shaped flange portion 28. An outer peripheral edge portion 30 of a piston stop 18 of rubber or the like arranged on an upper side of the strike cylinder 15 is arranged to extend in a lower direction from an upper end portion along an outer peripheral face of the strike cylinder 15 to thereby form an air exhaust valve seat 25 at a lower end of the outer peripheral edge portion 30. In addition, an air intake/exhaust path 32 for guiding compressed air from the main valve 21 to an upper end edge of the strike cylinder 15 is formed between an outer peripheral face of the cylinder seal 29 and an inner peripheral face of the outer peripheral edge portion 30 of the piston stop 19.
