COVER MEMBER

PROBLEM TO BE SOLVED: To prohibit the simultaneous operation of sliding displacement and rotating displacement of a cover member. SOLUTION: The cover member L includes a first lock mechanism E1 for restricting the sliding displacement of a second cover structural body 21 relative to a first cover structural body 20, and for permitting the sliding displacement of the second cover structural body 21 relative to the first cover structural body 20 in linkage with the operation of a sliding rod 70, and a second lock mechanism E2 for restricting the rotating displacement of the first cover structural body 20 relative to a body member B in the fall-down attitude of the first cover structural body 20, and for permitting the rotating displacement of the first cover structural body 20 relative to the body member B in linkage with the operation of an open rod 71. The sliding rod 70 has a first restricting mechanism F1 for restricting the motion of the second lock mechanism E2 during the operation of the sliding rod 70. The second lock mechanism E2 has a second restricting mechanism F2 for restricting the sliding displacement of the sliding rod 70 during the operation of the open rod 71. COPYRIGHT: (C)2010,JPO&INPIT
