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.

A dust collector having a filter for catching dust in air flowing in an intake path is provided. A pair of the intake paths are formed so as to be combined together on an upstream side of an electric blower provided in a main body. A pair of communication paths allow a discharge passage to communicate with each of the intake paths. A first opening and closing member is provided so as to open and close the intake path, and in a normal state, is biased to open the intake path. A second opening and closing member is provided so as to open and close the communication path, and in the normal state, is biased to close the communication path, and opens the communication path in response to a closing operation of the intake path by the first opening and closing member.
