摘要： The power tool has a power transmitting mechanism. When a tool bit is not pressed against a workpiece, the power transmitting mechanism is held in a power transmission interrupted state, and when the tool bit is pressed against the workpiece, the power transmitting mechanism is held in a power transmission state in which the tool bit moves together with the driven-side member in an axial direction of the tool bit so that the driving-side member receives the torque from the driven-side member and the tool bit is driven. Tapered portions are provided between the driving-side member and the driven-side member and inclined with respect to the axial direction of the tool bit. When the driven-side member moves in the axial direction of the tool bit, frictional force is caused on the tapered portions and the torque of the driving-side member is transmitted to the driven-side member by the frictional force.

One of the semi-cylindrical bearings is provided with a circumferential oil groove on its inner circumferential surface, and has two circumferential ends. The circumferential oil groove has an open groove end at at least one of the two circumferential ends, which one is a first circumferential end being directed to the same direction as a relative rotational direction of a crankshaft. The other semi-cylindrical bearing is provided with at least one circumferential local groove on its inner circumferential surface, and has two circumferential ends. The circumferential local groove has an open groove end at one of the two circumferential ends, which one is a second circumferential end being directed to the opposite direction to the relative rotational direction of the crankshaft. The circumferential oil groove and the local circumferential groove are in fluid communication with each other. At a region of the fluid communication, a groove bottom of the local circumferential groove is deviated toward an axis of the sliding bearing from another groove bottom of the circumferential oil groove. An axial groove is formed along a contact interface between the first and second circumferential ends.

摘要： Disclosed is a feature that collects dust particles that arise from a processing operation of an impact tool. The dust collection device collects dust that arises from of a processing operation and is attached to the impact tool that performs a pre-determined processing operation on a processed member by way of a tool bit mounted to the tip region of the tool body being linearly operated at least in the lengthwise direction. The dust collection device has a dust collection unit of which the tip opens as a dust intake port and the contour shape is formed unevenly around the long axis of the tool bit. The position of the dust collection unit is freely selected around the long axis of the tool bit, and it is possible to cause the position to change around the long axis of the bit.
