It is set smaller than the separation distance M. Thereby, when the piping cover 62 is rotated in a state where the stepped portion 82 is hooked on the second engaged portion 61, and the cover main body 76 is in a posture substantially parallel to the rear panel 18, the first engaged portion It becomes possible for 60 to face the upper escape portion 80 and to be positioned below the first engagement piece 64a (see FIG. 3B). That is, the first engaging piece 64 a can face a position where it can engage with the first engaged portion 60.

(Operation of Example)
Next, the operation of the injection type ice making machine 10 according to the embodiment will be described below. When the pipe cover 62 is attached to the pipe housing part 54, the lower part of the pipe cover 62 is inclined so as to protrude forward, and the second engaging part 66 is made to face the pipe housing part 54.
