Further, since the first projecting piece 12, the screw 19, the second projecting piece 13 and the projecting pin 15a of the operation panel 3 can be concealed by the top plate 4, it is necessary to add other parts for concealing them. Since there is no need to increase the number of parts, assembly is facilitated.

  Further, a part of the recess 1b of the washing machine casing 1 is close to or close to the rear surface of the control board mounting plate 3c in a state where the operation panel 3 is attached to the recess 1b of the washing machine casing 1. Since the housing mounting surface 18 projecting toward the operation panel 3 is provided so as to come into contact with the operation panel 3, the operation panel 3 is attached to the housing mounting surface 18 when the operation panel 3 is attached to the recess 1 b of the washing machine housing 1. Since the second through hole 13a and the projecting pin 15a and the third projecting piece 16 and the opening hooking hole 17 can be engaged only by sliding upward from the top, the first through hole 12a. There is no need to align the screw holes 14a, and assembly is easy.

  Further, since the position of screwing and fixing by the screw 19 of the first through hole 12a and the screw hole 14a is away from the opening 2, the detergent spilled when the laundry is taken in and out is tightened portion of the screw 19 Since the relationship between the third projecting piece 16 and the opening hooking hole 17 is abutting or close, the stress on the third projecting piece 16 is small. Therefore, it is easy to select materials for the washing machine casing 1 and the operation unit main body 3b.

  Furthermore, since the lower end portion of the operation panel 3 is not screwed to the washing machine casing 1, there is no need for a decorative member for hiding the screw provided on the outer peripheral portion of the opening portion 2, and the number of parts can be reduced. At the same time, the work man-hours can be reduced.
