Abstract: A dust collector for an electric power tool includes a main body case, a dust box, a sliding portion, and a dust collecting route. The main body case includes an exhaust port, the main body case being configured to be installed on an electric power tool. The dust box internally includes a filter. The sliding portion is disposed on the main body case. The sliding portion has a front end on which a nozzle with a suction opening is disposed. The sliding portion is slidable in a front-rear direction. The dust collecting route is from the suction opening to the exhaust port passing through the filter. The main body case includes a guiding portion through which the sliding portion passes, and the guiding portion allows the sliding portion to project rearward when the sliding portion slides.

Abstract: A hammer drill includes a boss sleeve rotatably and externally mounted to an intermediate shaft separately from the intermediate shaft. The boss sleeve includes a rod coupled to a rear end of a piston cylinder via a swash bearing. The boss sleeve is configured to rotate to convert a rotation of the intermediate shaft into a reciprocating motion in a front-rear direction of the rod and transmit the reciprocating motion to the piston cylinder. The hammer drill includes a second clutch disposed at the intermediate shaft. By performing a switch operation of a slide position of the second clutch, a hammer mode in which the second clutch is engaged with the boss sleeve to reciprocate the piston cylinder back and forth and another operation mode are selectable. The boss sleeve is rotatably cantilevered not to be in contact with the intermediate shaft by an inner housing via a bearing.

Abstract: A driving tool includes a driver moving along a driving passage and a lift mechanism for moving the driver. The driving tool includes a pusher and an idling strike prevention mechanism interlocking with a position of the pusher. The pusher pushes a driving member from a side opposite to a first end surface of a tool main body such that the driving member contacts a tip end of the driver at a standby position. When the driver moves from the standby position to a top dead center, the pusher supplies the driving member to the driving passage. After that, the driver moves downward to a driving position to drive the driving member. When no driving member is left, the idling strike prevention mechanism restricts activation of the driving tool in interlocking with the pusher such that the pusher moves to an activation restriction on a side of the driving passage.

Abstract: A hammer drill includes a housing inside which a motor, a tubular tool holder, a driving mechanism, a rotation conversion member, and an inner housing are disposed. The driving mechanism is configured to perform at least one of rotation actuation of the tool holder and hammering actuation of a bit. The inner housing supports the driving mechanism, supports the tool holder via a first bearing, and supports an output shaft via a second bearing. The inner housing is divided into a front housing holding the first bearing and a rear housing that is formed in a separate body from the front housing and holds the second bearing. The inner housing is formed by connecting the front housing to the rear housing in an axis line direction of the tool holder. A seal member sealing outside space of the inner housing inside the housing is disposed in the front housing.

Abstract: A driving tool includes a piston, a driver, and a lift mechanism. The piston moves in a driving direction by a pressure of a gas. The driver extends from the piston and includes a plurality of engaged portions. The lift mechanism moves the driver in a direction opposite to the driving direction. The lift mechanism includes a rotation shaft, a wheel, a plurality of engaging portions, and a supporting member. The wheel rotates integrally with the rotation shaft. Each of the plurality of engaging portions may engage an engaged portion. The supporting member supports the wheel so the wheel is allowed to move between an initial position and an eccentric position in a radial direction of the rotation shaft.

Abstract: An objective is to provide a technique to securely protect the striking tool even when the striking tool inadvertently falls down. A striking tool including a rotating shaft relatively rotatably connect a main body with a handle, a first elastic member reducing transmitting of vibration from the main body to the handle in a case that the handle relatively rotates to the main body, wherein the handle includes a battery mounting portion to which battery to drive the motor is attachable and the handle is arranged to relatively move to the main body across the rotating shaft, and an adjuster such that the relative movement amount of the handle to the main body in a predetermined direction is adjusted to be larger than the relative movement amount in a direction other than the predetermined direction.

Abstract: A power tool includes a motor, a driving mechanism, a main housing, a handle housing, a first guide part and a second guide part. The handle housing is movable relative to the main housing at least in a front-rear direction. The first and second guide parts are configured to guide relative sliding between the main housing and the handle housing in the front-rear direction. Each of the first guide part and the second guide part includes a first engagement part and a second engagement part engaged with each other to be slidable in the front-rear direction. The main housing has the first engagement part. The handle housing has the second engagement part. The second guide part is spaced apart from the first guide part and located rearward of the first guide part in the front-rear direction.
