Abstract
A dust collector for an electric power tool includes a main body case, a tubular sliding portion, and a dust collection portion. The main body case is mountable to an electric power tool. The tubular sliding portion is disposed on the main body case. The sliding portion includes a nozzle on a front end thereof. The nozzle includes a suction opening. The dust collection portion is configured to accumulate dust suctioned from the nozzle. The sliding portion includes a guided portion supported by a guiding portion disposed on the main body case. The guided portion is supported slidably in a front-rear direction, and the guiding portion and the guided portion are disposed in a region on a half side with respect to a line on a cross section passing through a center of the sliding portion.
