ABSTRACT:
A disc brake caliper support structure is disclosed which comprises a rear arm forming a cylinder containing a piston for pressing a friction pad supported and guided by an anchor pin and a front arm for fixing another friction pad to make a caliper holding disc rotors with both the friction pads therebetween movable in the axial direction of guide pins by inserting a plurality of guide pins installed on the caliper in the support member fixed to a bogie frame. One guide pin and the support member are floatably coupled in such a manner as to oscillate relative to each other through a spherical bush and a spherical member, each being set in position by the support member. The other guide pin and the support member are floatingly coupled in such a manner as to oscillate relative to each other through a vibration-proof cylindrical rubber member with a cylindrical inner liner formed with rubber whose outer peripheral axial threads are sawtooth-like in the peripheral direction.
