摘要： A chair according to the present invention has a reference position P located midway in a front-back direction in a movable range of a seat 2. The chair includes a return force generation mechanism 4 configured to generate a return force in a direction to return the seat 2 moved from the reference position P at least in the front-back direction to the reference position P. The return force generation mechanism 4 includes an elastic member 40 configured to increase the return force in the direction to return the seat to the reference position P as the amount of movement of the seat from the reference position P increases.

摘要： A chair includes: a leg 1; a seat 2; and a front-back support mechanism 4. The front-back support mechanism 4 is provided at a seat receiving part 50 directly supported by the leg 1, and the front-back support mechanism includes: a wavy plate 56 provided to horizontally extend from vertical walls 51 of the seat receiving part 50 and having mound-shaped surfaces 57, 58 each convexly curved upward; and followers 53, 54 provided at front-back support bodies 52 as supported parts and configured to move relative to the mound-shaped surfaces 57, 58 while contacting the mound-shaped surfaces 57, 58. The wavy plate 56 is associated with the followers 53, 54 such that a movement end inclines downward when the seat 2 moves from a neutral position in accordance with a relative movement between the mound-shaped surfaces 57, 58 and the followers 53, 54.

摘要： Two first binding members supported rotatably by a base, which will be fixed to a back cover, and two second binding members, which engage with the front ends of the first binding members to form closed loops, are provided. Spaces between the base sections of the first and second binding members are connected via a first and second connecting plate, respectively. A releasing means is disposed between the respective connecting members, and a force is given by the releasing means in the direction that the closed loops via binding members are released. It is such adapted that, when the first binding members are nipped by fingertips and given an operation force in the direction that the same come closer to each other, the engagement with the second members are released and the front ends can rotate in the direction that the same are opened.

摘要： A binder 10 has a base 14 having passages 14A, 14A through which binding legs 13, 13 can be inserted. The base 14 has a plurality of base-forming members 17, 17 that can move relative to each other along the longitudinal direction. Each of the base-forming members 17, 17 has first and second operating portions 22, 23 that move when the base-forming members 17, 17 are moved relative to each other. The second operating portions 23, 23 move away from each other and press the binding legs 13, 13 onto their binding positions when the first operating portions 22, 22 are moved toward each other. The binding legs 13, 13 are released and the first operating portions 22, 22 move away from each other when the second operating portions 23, 23 are moved toward each other.
