A flange partis provided on a vertical surfaceon the plate member PM of the front-rear swing part, the flange parthas a guide surfaceextending to lateral direction and moving the rolling bodyin the longitudinal direction, a lateral direction dimension of the guide surfaceis greater than a thickness of the plate member PM, the flange partand the portion of the plate member PM forming the vertical surfacearound the flange partare integrally formed of metal; and the flange parthas a shape that goes around the circumference of the guide holeopened in the vertical surface, and then, the rolling bodyare provided independently to the left and right, to be able to a roll along the guide surface

Chair

To provide a chair in which the seated person can perceive a comfortable sitting feeling even if sitting for a long time, and furthermore a high work efficiency can stably be maintained, a chair according to the present invention includes a support mechanisminterposed between a legand a seat, wherein the support mechanismincludes: a seat inclining mechanism Q as a seat inclining function configured to downwardly incline a tip side in an operation direction of the seatwhen the seatoperates from a predetermined reference position (S), and further includes: a return-force generation mechanism configured to generate, in accordance with an amount of movement, a return force in a direction of returning the seathaving moved from a reference position (S) in a front-rear or left-right direction, to the reference position (S).

Chair and seat support mechanism

A chair comprises: a legerected on a floor surface; a seatarranged above the leg; and a support mechanisminterposed between the legand the seat, wherein the support mechanismis arranged below the seatand is configured to movably support the seatalong a predetermined trajectory by having an omnidirectional connection unitconfigured to operably connect in all directions including the front-rear direction and the left-right direction, comprises: a seat inclining function configured to downwardly incline a tip side in a movement direction of the seat, and further comprises: a return-force generation mechanism configured to generate, by elevating a center of gravity of the seat, a return force in a direction of returning the seatto the reference position.

A chair includes a support mechanisminterposed between a legand a seat, wherein the support mechanismis arranged below the seat, is configured to each individually and movably support the seat, at least at two locations in a front-rear direction and two locations in a left-right direction, along a predetermined trajectory, and the support mechanismincludes: a seat inclining mechanism Q or a seat inclining function configured to downwardly incline a tip side in a movement direction of the seatin accordance with movement of the seat, and further includes: a center-of-gravity movement mechanism P or a return-force generation mechanism configured to generate a return force in a direction of returning the seathaving moved from a reference position (S) in a front-rear or left-right direction, to the reference position (S) by using a center-of-gravity movement.

A chair according to the present invention includes: a leg; a leg support pole; a support base; a movement mechanismlocated below a seat, the movement mechanismprovided with plural movement partsA,B configured to allow the seatto move in a certain area along a predetermined trajectory in a front-rear and left-right directions between the support baseand the seat, the movement mechanismbeing a support mechanism configured to support the seatso that the seatmoves in the front-rear direction and left-right directions; and plural cover membersarranged corresponding to the plural movement partsA,B. The plural cover membersare configured to move relatively in accordance with movement of the plural movement partsA,B and cover the support mechanism
