The turning door 50 is bent and deformed so that the end of the cover presses the lid body 11, and the engaging protrusion 57K moves to the turning shaft 50J (see FIG. 16B). As a result, the engagement between the engagement protrusion 57K and the engaged portion 35 is difficult to be disengaged, and the engagement between the engagement protrusion 57K and the engaged portion 35 can be maintained.

  Further, in this embodiment, the operator's finger can be passed through the notch 32 (specifically, the operation hole 33) and hooked on the grip 54 of the rotary door 50, and when the rotary door 50 is opened. The operability is improved. Moreover, since the rotary door 50 is provided with the auxiliary operation hole 55 adjacent to the grip portion 54 from the rotary shaft 50J side, it is possible to stabilize the grip of the grip portion 54 by the operator.

  Moreover, in this embodiment, since the elastic piece 57H of the engaging part 57 of the rotation door 50 inclines so that it may approach the rotation axis 50J side of the rotation door 50 toward the protrusion front end side, it rotates. By repeatedly opening and closing the door 50, the elastic piece 57 </ b> H is deformed so that the protruding tip portion is separated from the rotation shaft 50 </ b> J of the rotation door 50, and the engagement protrusion 57 </ b> K is engaged with the engaged portion 35. Is less likely to come off.

  Further, in the present embodiment, the engaged portion 35 is provided with a facing wall 37 that faces the elastic piece 57H from the rotating shaft 50J side of the rotating door 50 and engages with the engaging protrusion 57K in the closed state. Since the opposite wall 57 of the opposite wall 57 faces the opposite side to the rotation shaft 50J, an opposite inclined surface 37M is formed so as to be inclined away from the rotation shaft 50J toward the back side of the lid body 11. When the door 50 is closed, the elastic piece 57H is deformed so that the engaging protrusion 57K is separated from the rotating shaft 50J of the rotating door 50 along the opposing inclined surface 37M of the opposing wall 37. Then, when the engaging protrusion 57K is disposed on the back side of the lid main body 11 with respect to the opposing inclined surface 37M, the elastic piece 57H is restored, and the engaging protrusion 57K is engaged with the opposing wall 37. According to the present embodiment, the engagement protrusion 57K and the engaged portion 35 can be easily engaged when the rotating door 50 is closed.
