A brake cylinder device is provided that includes a clearance adjustment mechanism, can be made less likely to be affected by the surrounding environment such as temperature and humidity at low cost, and also can achieve a reduction in the radial dimension of a cylinder body. A threaded shaft 24 connected to a brake output portion 21 is accommodated inside a guide tube 25 attached to a piston 22. A pusher spring 26 biases the threaded shaft 24 in the braking direction. With respect to a clutch nut 27 threadably engaged with the tip of the threaded shaft 24, a front stopper 28 is disposed on the front side and a first clutch 29 and a second clutch 32 are disposed on the rear side so as to be capable of coming into contact with the clutch nut 27. Adjustment stoppers 30 are disposed so as to be movable relative to the clutch nut 27 and the guide tube 25 along the axial direction of the threaded shaft 24, and its movable range is restricted with respect to the cylinder body 20. An adjustment spring 31 is in contact, at a first end thereof, with the second clutch 32 to which the adjustment stoppers 30 are fixed, and biases the clutch nut 27 toward the anti-braking direction.
