Abstract:
Provided is a floating caliper brake device 100 for a railway vehicle, comprising: a support frame 1 having a cylindrical section 1a; a support pin 2 supported by the cylindrical section 1a so as to be slidable in an X-direction; a caliper 3 including a first arm 3a and a second arm 3b; a first brake shoe 4; a second brake shoe 5 facing the first brake shoe 4; a pressing device 6 for moving the first brake shoe 4 forward and backward; an elastic member 7 capable of extending and contracting in the X-direction; an engagement member 8 incapable of moving in the X-direction relative to the cylindrical section 1a; and a movement member 9 frictionally engaged with the support pin 2 so as to be slidable in the X-direction. The L-side ends of both the elastic member 7 and the engagement member 8 are individually supported by the cylindrical section 1a. A part of the R-side end of the engagement member 8 overlaps the movement member 9 when viewed in the X-direction. The R-side end of the elastic member 7 protrudes further toward the R-side than the R-side end of the engagement member 8 and is connected to the movement member 9.
