To obtain an operation room chair to be moved by a user using a foot.A seat (3) is provided at the upper end of a metal post (2) and a seat base (4) is provided at a lower end. Projections 4a to 4d are formed in the base base 4 in the front, rear, left and right directions, and between adjacent protrusions 4a to 4d on the edge portion of the base base 4 are smoothly pressed portions 4e to 4h recessed inward . The distance between the protrusions 4a, 4b in the front-rear direction is increased, the distance between the protrusions 4c, 4d in the right and left direction is shortened, and the casters 6a through 6d are attached to the lower face of each protrusion 4a through 4d. The user hips on the seat portion 3 and positions both feet in the vicinity of the pressing portions 4 e and 4 f. In order to move the chair 1, when one foot is brought into contact with the pressing portions 4e, 4f and pushed in the direction to move by the foot, the casters 6a through 6d rotate in that direction, so the user is blocking both hands Even with this, the chair 1 can be moved in an arbitrary direction.(FIG.【課題】使用者が足を使って移動させる手術室用椅子を得る。【解決手段】金属製の支柱2の上端に座部3が、下端に台座ベース4が設けられている。台座ベース4は前後左右方向に突部4a~4dが形成され、台座ベース4の縁部の隣接する各突部4a~4dの間は、滑らかに内側に凹む押圧部4e~4hとされている。前後方向の突部4a、4bの距離は長くされ、左右方向の突部4c、4dの距離は短くされ、各突部4a~4dの下面に、キャスタ6a~6dが取り付けられている。 使用者は座部3に腰をかけ、両足を押圧部4e、4fの近傍に位置させる。椅子1を移動するためには、片足を押圧部4e、4fに当接して、足により移動すべき方向に押すと、キャスタ6a~6dはその方向に回転するので、使用者は両手が塞がっていても、任意の方向に椅子1を移動させることができる。【選択図】図1
