PROBLEM TO BE SOLVED: To provide a lid structure which is easy to put on/off but cannot be simply removed if one does not know how to put in on/off. SOLUTION: When a blind lid 18 is to be mounted n a service opening 16, the lid 18 is pushed into the opening 16 while an index 31 and an index 32 are aligned. An engaging claw 24 elastically deforms to engage with the opening 16. Since the engaging claw 24 is set between an anti-rotating member 28 and a rotation stop member 29, an imprudent rotation of the lid 18 is prevented. When removing the blind lid 18, the lid 18 is rotated so that the engaging claw 24 comes beyond the rotation stop member 29, and the engaging claw 24 and a release notch 17 of the service opening 16 are aligned with each other. |
