A pneumatic clutch apparatus is described comprising: a pneumatic clutch disposed at the rear of a transmission and including a pneumatic actuator for engaging and disengaging the clutch, a rotary passage adapted to rotate together with the clutch and connected to the actuator; a stationary passage stationary with respect to the clutch and connected to a pneumatic pressure control mechanism disposed outside the clutch; and a rotary joint including a connecting passage for connecting the rotary passage and the stationary passage together; the rotary joint having a rotary portion to which the rotary passage is fixed and a stationary portion to which the stationary passage is fixed, and the stationary portion being fixed to a housing of the transmission and rotatably supporting the rotary portion. A cylindrical intermediate member is disposed between the rotary portion and the stationary portion of the rotary joint. Air passages in the stationary portion and the rotary portion are connected together through an air passage in the intermediate member. The intermediate member is rotatably fitted to the rotary portion and the stationary portion through seals which seal the air passage. A connecting mechanism is operable to connect the intermediate member to the rotary portion when the intermediate member and the rotary portion occupy a predetermined relative angular position.
