To provide an airflow forming member, which hardly contacts with other member even when it is turned over and used, and an air conditioner for a railway vehicle including the same.SOLUTION: A though hole 41 through which a rotating shaft of a motor is inserted is formed in a boss 40. An impeller 50 is fixed to the boss 40 while being in contact with an outer peripheral surface 43 of the boss 40 and generates airflow by being rotated together with the boss 40. Peripheral grooves 46, 47 having the depth in a direction parallel to the height direction and extending in a circumferential direction are formed between a peripheral edge of an opening of the through hole 41 and the outer peripheral surface 43 at each of one end and the other end of the boss 40 in the height direction parallel to the rotating shaft. When the boss 40 is fitted to the rotating shaft in a direction where the one end faces the motor, a cap 70 is fitted to the other end of the peripheral groove 47 to cover the opening of the other end. When the boss 40 is fitted to the rotating shaft in a direction where the other end faces the motor, the cap 70 is fitted to one end of the peripheral groove 46 to cover the opening of the one end.SELECTED DRAWING: Figure 2

    【課題】裏返して使用した場合でも他の部材との接触が起こりにくい気流形成部材と、これを備える鉄道車両空調機とを提供する。【解決手段】ボス40には、モータの回転軸が挿入される貫通孔41が形成されている。羽根車50は、ボス40の外周面43に接した状態でボス40に固定されており、ボス40と共に回転することにより気流を生成する。ボス40の、回転軸に平行な高さ方向の一端及び他端のそれぞれにおいて、貫通孔41の開口の周縁と外周面43との間に、高さ方向に平行な方向に深さを有し、かつ周方向に延在する周溝46、47が形成されている。一端がモータに面する向きにボス40が回転軸に嵌められる場合に、他端の周溝47に、他端の開口を覆うキャップ70が嵌められる。他端がモータに面する向きにボス40が回転軸に嵌められる場合には、一端の周溝46に、一端の開口を覆うキャップ70が嵌められる。【選択図】図2
