An opening/closing cover attachment structure which couples an edge of an opening/closing cover to a cover attaching body in a turnable manner, the opening/closing cover attachment structure comprising:
- a first hinge and a second hinge disposed on the edge of the opening/closing cover via an interval;
- and
- a holding part disposed outside between the first hinge and the second hinge, and capable of holding the opening/closing cover in a closing state and releasing the holding, wherein
- the first hinge includes a hinge pin provided in one of the cover attaching body and the edge of the opening/closing cover and a pin insertion hole provided in the other of the cover attaching body and the edge of the opening/closing cover,
- the hinge pin has an insertion portion inserted into the pin insertion hole and a fitting portion inserted into a pin fitting hole provided in the one of the cover attaching body and the edge of the opening/closing cover,
- the fitting portion and the pin fitting hole are formed to have a non-circular cross section, and the insertion portion and the fitting portion are eccentrically disposed,
- the first hinge is switched between a first state where the fitting portion is inserted into the pin fitting hole in a first posture and a second state where the fitting portion is inserted into the pin fitting hole in a second posture where the hinge pin is turned by a predetermined angle in a circumferential direction from the first posture,
- the insertion portion in the second state is shifted in a front-and-rear direction of the opening/closing cover with respect to the insertion portion in the first state,
- by manually switching between the first state and the second state according to a level difference between contact end portions of the opening/closing cover in the closing state and the cover attaching body, hinge axes of the first and second hinges are shifted in a front-and-rear direction of the opening/closing cover so that the level difference can be reduced,
- the second hinge includes a hinge pin provided in one of the edge of the opening/closing cover and the cover attaching body and a pin insertion hole provided in the other of the edge of the opening/closing cover and the cover attaching body,
- one of the hinge pin and the pin insertion hole is provided in a supporting bracket provided in the opening/closing cover,
- a spacer is provided so as to be interposed or not to be interposed between the supporting bracket and a supporting bracket attachment face formed in the opening/closing cover,
- it is configured to be switched into a spacer interposition state where the spacer is interposed between the supporting bracket and the supporting bracket attachment face and a spacer non-interposition state where the spacer is not interposed between the supporting bracket and the supporting bracket attachment face,
- the opening/closing cover in the spacer interposition state is shifted in the front-and-rear direction of the opening/closing cover with respect to the opening/closing cover in the spacer non-interposition state, and
- by manually switching between the spacer interposition state and the spacer non-interposition state according to the level difference, the hinge axes of the first and second hinges are shifted in the front-and-rear direction of the opening/closing cover so that the level difference can be reduced.
