When the outer tub 210 is located at the assembling position, the elastic member 294 may abut against the locking part 292 to prevent the outer tub 210 from being forwardly removed from the assembling position.

In an embodiment of the present invention, the locking part 292 is disposed on the cover 2121 of the outer tub 210 and protrudes upward from the upper surface of the cover 2121, and the elastic member 294 includes a free end 2942 and a fixed end 2944 connected to the cabinet inner 130. In the movement of the outer barrel 210 from the fitting position to the disengagement position, the free end 2942 protrudes on the rear movement path of the projection 2922 so as to abut against the locking portion 292 to restrict the forward movement of the outer barrel 210.

When the locking portion 292 is in contact with the elastic member 294 during the movement of the outer tub 210 from the fitting position to the disengagement position, the front end surface 2946 of the elastic member 294 is in contact with the rear end surface 2922 of the locking portion 292, and the locking portion 292 pushes the elastic member 292 to be deformed such that the locking portion goes over the elastic member 294. In order to allow the locking portion 292 to smoothly pass over the elastic member 294, at least one of the front end surface 2946 of the elastic member 294 and the rear end surface 2922 of the locking portion 292 is an inclined surface. In an embodiment of the present invention, the front end surface 2946 of the elastic member 294 and the rear end surface 2922 of the locking portion 292 are inclined.

As a further improvement of the present invention, the rear end surface 2948 of the elastic member 294 and the front end surface 2924 of the locking portion 292 are provided as planes perpendicular to the front-rear direction, and in the movement of the outer tub 210 from the fitting position to the disengagement position, the rear end surface 2948 of the elastic member 294 abuts against the front end surface 2924 of the locking portion 292 from the front to restrict the forward movement of the outer tub 210.
