PROBLEM TO BE SOLVED: To provide a lock mechanism of an opening and closing member, which can solve a problem of unbalanced closure in the opening and closing member, by simple constitution, without increasing a cost.SOLUTION: The lock mechanism of the opening and closing member 22 includes the lock mechanism of an opening and closing member 22 turned around a turning shaft N as the center with respect to a conveyer body in a fixed side, to open and close an opening part of the conveyer body, and a lock (locking member) 29 for holding a closed state of the opening and closing member 22, and the lock 29 is arranged in an one place of approximately central part 1 in parallel direction (width-direction) to the turning shaft N of the opening and closing member 22. A protrusion 30 abutting on the conveyer body is formed in the vicinity of both end parts in parallel direction (width-direction) to the turning shaft N of the opening and closing member 22. |
