<p>PROBLEM TO BE SOLVED: To lengthen a distance between a pair of sliding fulcrums so as to improve parking brake efficiency, and facilitate a bearing surface processing for an anchor pin, in an axle housing integrated with an anchor block. SOLUTION: A cable aperture 4 is provided to an axle housing 1 which is closer to an axle center than an anchor block 3, an anchor pin 11 is fixed at both sides of the cable aperture 4, a head 11a of the fixed anchor pin 11 is composed to be a sliding surface 12 where a sliding fulcrums of a pair of toggle levers 6 slides respectably, a pin fixing aperture 10 of the axle housing 1 fixing a pair of the anchor pins 11 is provided at an inside which is closer to the axle center than on a circumference R passing through an axle wall surface 3a of an anchor block 3 at a center of the axle center, and the head 11a of a pair of the anchor pins 11 is composed to be larger so as to set a broad distance between a pair of sliding surfaces 12.</p> |
