To provide, in view of the problems, a washing device which can improve washing efficiency, operability and washing performance.

The washing device includes two brush driving mechanism 3 having two separate brushes 9 which are brought into contact with target washing faces 72. Each brush driving mechanism 3 has: a rotation driving part 8; a brush 9; and a drive transmission mechanism which transmits the rotating motion of the rotation driving part 8 to the brush 9 so that the brush 9 revolves around the rotation axis of the rotation driving part 8 without rotating around itself. The washing device also has two holding parts 4 holding the two brush driving mechanism 3 separately; and a device body 2 which pivotally supports the two holding parts 4 so that a relative angle can be changed and which has an operating handle 6.
