PROBLEM TO BE SOLVED: To obtain a three side frame apparatus at an elevator landing stage in which a gap at a joint between a front plate and a vertical frame body is eliminated and designability is raised. SOLUTION: A central front plate 17 is constituted so as to be guided by the base 21a of a mounting metal 21 and the folded side 13c of the vertical frame body 13 and moved in a direction approaching an opening 5 to be closed, and moved in a direction apart from the opening 5 to be pulled out. Permanent magnets 22, 24 hold the central front plate 17 in a closed state by magnetic attraction force. A latch 25 makes a stopper 26 be engaged with the top end side 17a of the central front plate 17 to regulate movement of the central front plate 17 in a pulling out direction, and engagement with the top end side 17a is released by the operation of a release lever 29 connected via a wire.
