摘要： An electric circular saw of the type including a mechanism for tilting a base relative to the plane of a blade is provided wherein a side knob for being gripped by the user during cutting operation pivotally connects the base and a body of the circular saw through a base attachment portion and a bevel plate having an arcuate guide groove extending through an angular distance corresponding to a tilt angle of the base relative to the blade. The side knob is threaded to the base attachment portion and movable together with the base when the base is tilted. The side knob is spaced from a guide surface of the base by a distance at least larger than a maximum radius of the side knob. The distance between the base and the side knob is constant regardless of the relative angular position of said base and the blade, so that circular saw can be held stably and hence is capable of performing an accurate cutting operation.

摘要： An electric-powered tool comprises: a housing; and a brush motor contained in the housing, having: brush holders, each of brush holders holding a carbon brush; and brush terminals, made of an electrical conductive and elastic material having at least one blade portion, a palm portion, and an arm portion, for providing electrical connection thereof to the brushes through the brush holder by catching and griping the brush holder by the blade and the palm portions, the arm portion extending from the palm portion to an end where a fixing portion is provided, each of the brush terminals being fixed by the fixing portion with a positional offset to develop a contact pressure between the palm portion and the brush holder. Further, the arm portion is further extending over the fixing portion to form a connecting portion. On the other hand, one end of a field coil is connected to a connector. Thus, the brush holder is connected to the field coil through the connection portion and the connector.

摘要： A power tool includes an internal wiring structure having a first terminal board secured to a commutator motor stator and a second terminal board releasably engaged with the first terminal board to electrically connect terminals on the first and second terminal board. The second terminal board includes first and second conductive resilient brush terminals respectively resiliently engaged with first and second conductive brush holders when the stator is installed in a housing of the power tool. Internal wiring of the power tool is thereby automatically completed upon installation of the stator in the housing.
