PROBLEM TO BE SOLVED: To provide a bolt polishing device excellent in workability without needing troublesome mounting work. SOLUTION: A pair of cylindrical stationary brushes 3a, 4a are journalled onto a base 1 so as to be parallel to each other, a bolt B is axially placed between both brushes 3a, 4a, and the brushes 3a, 4a are respectively rotatable around shafts by a motor 6. One end side of an oscillating frame 17 is pivotally supported on a base 1 by a horizontal shaft 20 so as to be vertically oscillated above the stationary brushes 3a, 4a. A cylindrical pressing brush 22a is journalled to the oscillating frame 17 parallelly to the stationary brushes 3a, 4a so as to be rotatable around a shaft by the motor 6, and the pressing brush 22a is lowered onto the bolt B placed between the stationary brushes 3a, 4a. The oscillating frame 17 is provided with a handle 21 for manually oscillating the oscillating frame 17, and the handle 21 is provided with a switch 24 for controlling the brush driving motor 6.
