Abstract: A washing device is provided which reduces a load on a user while ensuring favorable operability and safety. An opening/closing door (2) includes, at a front surface thereof, a control panel (3) which includes at least a setting portion (4) and a display portion (5), a handle portion (8) for operating a holding portion used in opening/closing the opening/closing door (2), a cover (7) which covers the handle portion (8) during washing of a to-be-washed object, and first detection means which detects movement of the cover (7). The cover (7) is provided so as to be movable between the handle portion (8) and the control panel (3). By moving the cover (7) during washing of the to-be-washed object, the cover (7) causes the handle portion (8) to appear on the front surface of the opening/closing door (2) to enable an operation of the holding portion and disables an operation of the control panel (3) by covering the control panel (3).
