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 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 lever device is configured such that, when first and second plates are relatively moved in a direction in which a second end part of the first plate and a fourth end part of the second plate are close to each other from a state in which the second end part and the fourth end part are separated from each other in an axial direction of a bolt, the first plate is rotated around a fulcrum positioned between a first engagement part and the second end part in the crossing direction so that the first plate is moved from an engaged position where the first engagement part and a non-circular part of the bolt or a nut are engaged to a non-engaged position where they are not engaged, and thereby removing a restriction of the relative rotation of the first plate to the non-circular part.
