Abstract
A brake for a hoist gear is provided with a pair of brake shoes for braking a disk to be braked arranged on a winding drum side by pressing both sides of the disk. Floating pin fitting piece portions protrude integrally from a body of a bearing supporting the winding drum. A caliper is attached to the fitting piece portions through floating pins. Axis points of the floating pins are arranged in point symmetry of approximately 180.degree. in respect of an axis point of a push rod inserted into the caliper in order to uniformly contact the disk face.
