A front leg 10 turns while sliding on a surface of the guide part 31, upon coming-out of a lock part 10c from the withdrawal port of a lock device 20. Upon landing of a support leg 25 as a front end part of a seat cushion, the front leg 10 comes to a downward and frontward end position of the gude part 31, thereby a turning attitude of the front leg 10 can be controlled.</p> |
