<P>PROBLEM TO BE SOLVED: To provide a chair in which the shock, generated when a seat body is moved to a front position, can be reduced, and the seat body can be easily moved. <P>SOLUTION: The seat body 10 of the chair 1 is supported by a front leg 30, a rear leg 40, and a leg support 20 so as to be swingable in the front-to-rear direction. When the seat body 10 is located between a rear position (A) and a second reference position (C), the seat body 10 is urged forward by the urging force of the gas spring 50. When the seat body 10 is located between a first reference position (B) and a front position (D), the seat body is moved forward by own weight. Thus, the seat body 10 is moved forward only by the gas spring 50 between (A)-(B), moved forward by the gas spring 50 and own weight between (B)-(C), and moved forward only by own weight between (C)-(D). That is, unless external force is applied to the seat body 10, the seat body is automatically moved to the position (D). <P>COPYRIGHT: (C)2012,JPO&INPIT |
