Abstract
In a body of an electric actuator, dust collecting pipes are disposed as a pair along an axial direction of a hole portion of the body. The dust collecting pipes are connected respectively to negative pressure supply ports provided in an end block, and include plural first through fifth suction holes separated mutually along an axial direction of the dust collecting pipes. Distances between the first through fifth suction holes are formed so as to become smaller stepwise from one end side of the dust collection pipes, on the side of the negative pressure supply ports, to the other end side thereof.
