PROBLEM TO BE SOLVED: To reduce force necessary for opening and closing an opening/closing member.SOLUTION: A holding mechanism of an opening/closing member (7 to 37) includes: an opening/closing member (U4) that is openably/closably supported with respect to a support (U1); holding members (27 to 37) that are rotatably supported by the support (U1); a pressing member (21) that is supported by the opening/closing member, and moves the holding members (27 to 37) to holding positions when the opening/closing member (U4) is closed; a grip part (7) that can be gripped and rotated by an operator; and a holding target member (18) that is supported by the opening/closing member (U4), can be rotated in conjunction with the movement of the grip part (7), and can be rotated, while the opening/closing member (U4) is closed, between a holding target position of being held by the holding members (27 to 37) that have moved to the holding positions and a separation position of being separated from the holding members (27 to 37). |
