  "textContent": "A brake cylinder device is provided that can prevent an unintentional release of a braking force of a spring brake means due to disengagement of meshing portions of a clutch mechanism. A brake cylinder device (1) includes a service brake means (11) including a first piston (24), a spring brake means (12) including a second piston (27), a clutch mechanism (14), a spindle (15), and a spindle holding means (16). The spindle (15) is connected to the first piston (24) so as to be rotatable about an axial direction. The clutch mechanism (14) includes a nut member (33) that is supported rotatably by the second piston (27) and screwed to the spindle (15), and connects or disconnects the spindle (15) and the second piston (27). The spindle holding means (16) restricts the rotatable angle of the spindle (15), and holds the spindle (15) with respect to the first piston by urging the spindle (15) in a direction that is opposite to a rotation direction in which the nut member (33) is deeply screwed to the spindle (15).",
