PROBLEM TO BE SOLVED: To enhance assembly efficiency and to easily achieve a form high in safety in a chair whose seat part is moved back while being elevated when rocked. SOLUTION: The front part of a seat receiving body 7 and a base body 2 are connected by a front link 23, and the rear part of the seat receiving body 7 is connected to a rocking member 18. The rocking member 18 is connected to the base body 2 by a first shaft 19. A rear engaging pawl is formed at the rear part of the seat receiving body 7, and it is fitted from the rear to a rear engaging pin 20. The rear engaging pin 20 is supported by an upper cover 25 mounted on the base body 2. While supporting the rear engaging pin 20 by the upper cover 25, pretension is applied to elastic means (rubber) for rocking. Since the rear engaging pin 20 is supported by the upper cover 25, the seat receiving body 7 can be attached while setting a back frame 10, and thus assemblability is excellent. A space for preventing a finger from being clamped can be easily opened between the seat receiving body 7 and the upper cover 25. COPYRIGHT: (C)2011,JPO&INPIT |
