Abstract

A device for cleaning cylindrical objects such as bolts has a sleeve (1) which contains a rotor (2) equipped with a brush (7). A bolt is inserted into the sleeve (1), and the rotor (2) is rotated by a motor (4) to clean the periphery of the bolt. The sleeve (1) is connected to a suction means of negative pressure such as blower (11), and the motor (4) is capable of rotating the rotor (2) in one or the other direction. In the cleaning device a bolt is enclosed in the sleeve (1) and is cleaned with the brush (7) which is driven in contact with the peripheral surface of the bolt by the rotation of the rotor (2). Dust and dirt generated by the cleaning are prevented from leaking out of the sleeve and collected in the suction means of negative pressure. As the rotor (2) rotates in one or the other direction by the motor (4), furthermore, the rotating direction of the brush (7) is set to meet the direction in which the lead of the thread of the bolt advances.
