Abstract: A reciprocating tool includes a motor, a reciprocating member, and a crank mechanism. The motor is disposed in a housing. The reciprocating member projects from the housing. The crank mechanism converts rotation of a rotation shaft of the motor into reciprocation of the reciprocating member. The crank mechanism rotates around an axis in a lateral direction by rotation transmission from the rotation shaft, and the crank mechanism includes a crank member having an eccentric pin, a connecting rod coupling the eccentric pin to the reciprocating member, and a balancer coupled to the eccentric pin, and the balancer is supported by the eccentric pin alone in the housing.

Abstract: A reciprocating tool includes a housing, a first tubular member, a slider, a second tubular member and a lock member. The first tubular member is pivotable around a first axis and has a single first protrusion protruding radially inward. The second tubular member is disposed in the first tubular member, is coupled to a first end portion of the slider to be pivotable around a second axis, and has a single second protrusion protruding radially outward. The second tubular member has a protruding portion configured to allow the lock member to move from a lock position to an unlock position. The single first protrusion is configured to engage with the single second protrusion and cause the second tubular member to pivot when the first tubular member pivots. The single second protrusion is provided on a portion of the second tubular member other than the protruding portion.

Abstract: A reciprocating cutting tool switches stably between the on and off states of orbital action or between the degrees of orbital action. The reciprocating cutting tool includes a rod-like slider reciprocable in a front-rear direction, a blade holder at the front end of the slider, an orbital unit that causes the blade holder to perform orbital action vertically in response to reciprocation of the slider, and an orbital switcher that switches between orbital modes operable by the orbital unit. The orbital switcher includes a lever body extending laterally. The lever body includes a first flat surface to support the slider indirectly. The first support flat surface includes a first portion frontward from a lateral central axis of the lever body and a second portion rearward from the central axis.

Abstract: A reciprocating tool includes a housing, a support body, a slider, a motor, a driving mechanism, a first biasing member, a manipulation member and a first change mechanism. The housing has a first axis that defines a front-rear direction of the reciprocating tool. The support body is supported within the housing. The slider is supported by the support body to be linearly movable. The driving mechanism is operably coupled to the slider and configured to reciprocally move the slider relative to the support body using power of the motor. The first change mechanism is operably coupled to the manipulation member and configured to selectively enable and disable the first biasing member to bias the slider in response to manipulation of the manipulation member. When biasing of the slider by the first biasing member is enabled by the first change mechanism, the first biasing member biases the slider downward.

Abstract: A dust collection device, that collects dust particles generated by an impact tool, has a feature that enables the attachment of the device to the impact tool, which is not provided with an attachment section for the device. The dust collection device has a tool body and an auxiliary handle, attached removably to the tool body, and is attached to an electric hammer that, in the lengthwise direction, linearly operates a tool bit mounted to the tip region of the tool body, and collects dust generated by the electric hammer. The dust collection device has: a dust collection unit that has a dust intake port at the tip; a dust collection hose, connected to the dust collection unit, for transferring dust to the downstream side; and a hose-holding unit that holds the dust collection hose. The hose-holding unit can be attached to and removed from the auxiliary handle.

Abstract: A reciprocating cutting tool reduces dispersion of dust. The reciprocating cutting tool includes a reciprocation converter drivable by a motor, a rod-like slider connected to the reciprocation converter to be reciprocable, a blade holder at the front end of the slider to hold a blade, a power transmission housing housing the reciprocation converter and allowing the slider to protrude from its front end, a cover outward from the power transmission housing, and a fan rotatable together with a rotor in the motor. A first passage of cooling air from the fan is defined between the power transmission housing and the cover. The first passage branches into a second passage toward the blade holder and a third passage not toward the blade holder.
