摘要： A hammer holder, provided between a retainer sleeve and a cylinder, slidably holds an intermediate member in an axial direction. A predetermined clearance is maintained between the hammer holder and the retainer sleeve. The hammer holder has a recessed portion which is engageable with a flange of the intermediate member so as to restrict the slide movement of the intermediate member. A cushioning member receives a percussion force when the flange is stopped by the recessed portion. The clearance restricts a compression amount of the cushioning member so that a predetermined life of the cushioning member is assured.
摘要翻译：设置在保持套筒和气缸之间的锤保持器沿轴向方向可滑动地保持中间构件。在锤保持器和保持器套筒之间保持预定的间隙。锤保持器具有可与中间构件的凸缘接合的凹部，以限制中间构件的滑动运动。当凸缘被凹部停止时，缓冲构件接收击打力。间隙限制了缓冲部件的压缩量，从而确保了缓冲部件的预定寿命。

摘要： A reciprocating tool (1) includes a housing (20, 30), a driving source (21), a reciprocation conversion unit (34, 36), —and a vibration reduction mechanism (30). The driving source is accommodated in the” housing. The reciprocation conversion unit (34, 36) is supported by the housing and is configured to convert a driving force of the driving source into a reciprocating motion for providing a tool bit (16) movably supported to the housing with a reciprocating motion. The vibration reduction mechanism (70) includes a shaft (72), a weight (71), a support member (73), and a urging portion (74). The shaft i(72)s supported by the housing and extending in a direction perpendicular to directions of the reciprocating motion of the tool bit (41) t and has an axis. The weight (71) is located away from the shaft (72) and is swingable in a swinging direction. The support member (73) swingably supports the weight (71) about the axis of the shaft (72). The urging portion (74) urges the weight (71) toward a prescribed position of the weight in the swinging direction with respect to the housing.

摘要： An elastic unit includes a transatory unit including a first elastic support member, a second elastic support member and not-shown four round bar-shaped elastic bodies made of rubber. A rotation urging unit is composed of a Neidhart spring including an outer frame, a shaft, a rotary member, and four rubber rods. The rotary member is in a state where it is rotated at 10° counterclockwise from an initial state. Therefore, the rubber rod deforms upon reception of rolling friction from the outer frame and the rotary member, and the rotation urging unit gives the handle portion the urging power by which the handle portion is rotated so that one end of the handle portion is spaced away from a gear housing 31 in the direction of the handle portion.
