摘要： A power tool (1), such as a multi-tool, includes: a motor (21) extending in a front-rear direction; a motor housing (2) that houses the motor (21); a head housing (7) held forward of the motor housing (2); and an output shaft (60) protruding downward from the head housing (7). The head housing (7) may be made of a resin. In addition or in the alternative, the head housing (7) includes a lower-head housing case (4) screw fastened to an upper-head housing cover (5). In addition or in the alternative, the motor housing has a two-halved structure in which two half housings (2a, 2b) are screw fastened together.

摘要： An electric tool, such as an angle driver, has a main tool body with a front portion and a rear portion positioned opposite to the front portion. The main tool body houses a motor configured to receive electricity to function as a drive source. A gear head is coupled with the front portion of the main tool body wherein the gear head has a spindle in communication with a motor axis of the motor via mesh-engagement of bevel gears associated with the motor axis. The spindle has with a cutter tool accessory attached thereto such that rotation of the motor axis produces a commensurate rotation of the cutter tool accessory. Battery attachment portions are associated with the rear portion of the main tool body and are configured to receive a corresponding set of batteries that provide electricity to power the motor.

摘要： Several means 71, 72, 73, 74, and 75 are provided for restricting a relative displacement in a separating direction of half-split housings 50L, 50R. At one or more of several screw-connection parts 60 of the left and right half-split housings 50L, 50R, a press-fitting protrusion 71a is provided in an insertion hole 62a of a boss-receiving part 62 into which a screw-boss part 61 is inserted. By press-fitting the screw-boss part 61 to the boss-receiving part 62, a separation resistance may be introduced between the left and right half-split housings 50L, 50R.

摘要： A grinder (100) includes a motor (12), a housing (4, 6, 30), a spindle (24), a first cover (120), and a second cover (170). The spindle protrudes downward from the housing, is driven by the motor, and thereby rotates. The first cover is provided in the circumferential direction of the spindle, is fixed to the housing, and at least partially covers a tool accessory (40), which is mounted on the spindle, from above. The second cover is detachably mounted on the housing (6) independently of the first cover.
