Latest Patents

Harumi Ooshima holds a patent for a disc brake design. This invention involves a unique mechanism where one brake pad is pressed against the disc rotor by a piston of a caliper, which is floatably supported on the carrier. In reaction, the other brake pad is pressed against the disc rotor by a claw portion on the caliper, producing a reliable braking force. During brake release, the spring force of a return spring separates the brake pad from the disc rotor. A positioning convex portion is provided on the carrier adjacent to the return spring, which restricts the sideward movement of the distal end portion of the return spring. This design prevents displacement and deformation of the return spring, ensuring its functions are maintained effectively.
