PROBLEM TO BE SOLVED: To prevent damage to a bed front plate or a bed box caused when a free leg piece of an angle bar moves to a leg standing position by arranging a forced guide mechanism for at least pulling-out motion of the angle bar. SOLUTION: An angle bar 3 can move by being forcedly guided to a leg standing position from a starting position in the pulling-out direction 4 and the rotational direction 5 from the starting position. One leg piece 6 of the angle bar 3 is movably supported in the pulling-out direction 4 and the rotational direction 5 through two bearing bushes 8 in mutually facing two side walls 7 of a holding body 2. The respective bearing bushes 8 are inserted into and fitted to bearing holes respectively bored in both side walls 7. Motion of the angle bar 3 is regulated by a slot-like guide cutout part 10 arranged in the holding body 2, and the angle bar 3 is forcedly guided in the guide cutout part 10 through a guide pin 11. The other free leg piece 12 of the angle bar 3 forms a leg standing column of a leg metal fitting 1 in the leg standing position of the angle bar 3. |
