To provide a cabin of a work machine where dust hardly enters in a gap between a support rod and a door.SOLUTION: A cabin of a work machine includes: a first support rod provided at one end in the width direction of the cabin; a second support rod located further backward than the first support rod, and for defining an entrance of the cabin together with the first support rod; a door supported by the second support rod so as to rotate between a closed position for closing the entrance and an open position for opening the entrance; and an elastic member provided inside of a beam for defining a front edge of the door and elastically compressed between the first support rod and the beam, when the door is in the closed position. An outer surface of the beam includes, when the door is in the closed position, a first surface containing a point on a virtual curve surface along the outer surface of the first support rod, and a second surface curving toward the inside of the virtual curve surface from a front end of the first surface.SELECTED DRAWING: Figure 3 【課題】支柱とドアとの間の隙間に塵埃が進入しにくい作業機械のキャビンを提供する。【解決手段】作業機械のキャビンは、キャビンの幅方向の一端に設けられた第１支柱と、第１支柱より後方に位置し、第１支柱と共にキャビンの出入口を画定する第２支柱と、出入口を閉鎖する閉位置、及び出入口を開放する開位置の間を回動可能に第２支柱に支持されたドアと、ドアの前縁を画定するビームの内側に設けられて、ドアが閉位置のときに、第１支柱及びビームの間で弾性圧縮される弾性部材とを備え、ビームの外面は、ドアが閉位置のときに、第１支柱の外面に沿う仮想曲面上の点を含む第１の面と、第１の面の前端から仮想曲面の内側に向けて湾曲する第２の面とを有することを特徴とする。【選択図】図３
