Abstract: A work tool switches smoothly between operational modes and has a lever member that is easily joined. The work tool includes an operation member, a lever member, and a switching member. The lever member is swingable about a support shaft in response to an operation on the operation member and is swingable with the support shaft placed through the lever member. The lever member has an elongated hole through which the support shaft is placed. The elongated hole extends along the lever member. The switching member is linked with a swing of the lever member to move linearly.

Abstract: A cutting tool includes a rotary blade driven by a motor, a fixed blade disposed opposing the rotary blade, a housing holding the motor, and a battery mount part on a rear portion of the housing. The battery mount part has a guide groove that slidably receives a rail of a power tool battery pack. A blade cover is disposed partially around the rotary blade, and a portion or all of the blade cover has a shape in which the farther forward it goes the more it goes toward the side that has the fixed blade, viewed from the rotary blade. A base holds the fixed blade, and a portion or all of the base has a shape in which the farther forward it goes the more it goes toward the side that has the fixed blade, viewed from the rotary blade.

Abstract: An autofeed attachment (4) for a screw-driving apparatus (2) includes a base casing (30), a feeder casing (32) slidably mounted on the base casing (30) and a wheel (72) rotatably mounted within the feeder casing (32). When rotated in a forward direction, the wheel (72) advances a screw strip (50), which has a plurality of screws (52) coupled by a connecting strip. A wheel forward-direction rotating mechanism (60, 64, 66, 68) rotates the wheel (72) in the forward direction and restricts rotation of the wheel (72) in a reverse direction opposite the forward direction. A wheel-release mechanism (70, 107, 117) releases the restriction placed on rotation of the wheel (72) in the reverse direction. The wheel forward-direction rotating mechanism and the wheel-release mechanism are disposed, at least partially, inside of the wheel (72) and/or the rotational axis of the wheel (72) intersects a release button (107) of the wheel-release mechanism.

Abstract: An auxiliary handle (10) comprises a first clamp member (21), a second clamp member (31), an operation rod (40) and a grip (50). By rotation of the operation rod (40), the first clamp member (21) is moved toward a distal end of the operation rod (40), and at the same time, the second clamp member (31) is moved toward a base end of the operation rod (40). Accordingly, the first clamp member (21) and the second clamp member (31) are moved to be close to each other. As a result, an auxiliary handle attachable part (140) of a screw driver (100) is clamped by the first clamp member (21) and the second clamp member (31), and thereby the auxiliary handle (10) is attached to the screw driver (100).

Abstract: A power tool includes a reducer that has a small size in an axial direction and is highly durable, although including a transmission mechanism. The power tool includes a motor, a reducer that reduces rotation from the motor, and an actuator to be actuated by the rotation reduced by the reducer. The reducer includes at least two stages of internal gears aligned in an axial direction, a preceding planetary gear and a succeeding planetary gear adjacent to each other in the axial direction to revolve within the internal gears, and at least two stages of carriers aligned in the axial direction. A carrier of the carriers supports the preceding planetary gear and the succeeding planetary gear radially overlapping each other with a single pin.

Abstract: To reduce size increase, an impact tool includes a motor, a spindle located frontward from the motor and rotatable by the motor, a hammer supported by the spindle, an anvil strikable by the hammer in a rotation direction and having an insertion hole extending rearward from a front end of the anvil, a locking member supported by the anvil and movable to a locking position for locking a tip tool placed in the insertion hole and to an unlocking position for unlocking the tip tool, and a bit sleeve surrounding the anvil. The bit sleeve is movable to a movement-restricting position for restricting radially outward movement of the locking member and to a movement-permitting position for permitting radially outward movement of the locking member. The bit sleeve is at least partly between the hammer and the anvil in a radial direction.
