Claims

[Scope of utility model registration request]

A pivot shaft is provided with a pair of brake arms having brake shoes, and a spring holder for a return spring that is installed between these brake arms and biases the brake arm in the expansion direction, and the spring holder is provided with: A caliper brake that is supported to rotate freely relative to the pivot shaft to adjust the spring force acting on the brake arm has a threaded portion at one end and an operating portion at the other end, and the caliper brake has a threaded portion at one end and an operating portion at the other end. An adjusting screw having an engagement groove is formed between the adjusting screw and the operating portion, and a support body having a holding portion for the adjusting screw and a slider guide surface is attached to the pivot shaft so as to be non-rotatable. an insertion hole in the holding portion of the support body through which the threaded portion of the adjustment screw passes; and an insertion hole that is continuous with the insertion hole;
and a retaining hole that engages with the engagement groove and prevents axial movement of the adjustment screw, so that the adjustment screw is only rotatably supported in the holding portion, while the adjustment screw is A caliper brake, characterized in that a slider having an interlocking part that interlocks with the spring holder and a sliding surface facing the guide surface is screwed onto the screw.
