Latest Patents

One of Toriyama's latest patents is a cylinder device for a disk brake. This invention aims to facilitate the installation of thick ring portions of a dust boot into an inner circumferential groove in a cylinder bore while also reducing the weight of a caliper. The design includes a piston that is slidably received in the cylinder bore at an actuating portion of the caliper. One thick ring portion is installed into an outer circumferential groove of the piston, while another thick portion is installed into an inner circumferential groove adjacent to the open end of the cylinder bore. The dust boot features an intermediate flexible portion received in a stepped large diameter bore that steps up from the cylinder bore. A cutout is formed on a peripheral portion of the stepped large diameter bore, surrounding and covering the intermediate flexible portion of the dust boot.

Another significant patent is for a disk brake apparatus that features a non-circular brake lever bore and matching connection portion. This disk brake mechanism includes an exposed portion of the camshaft that serves as a connection point with a non-circular radial cross-section. The brake lever has a corresponding non-circular bore that engages the connection portion. A caulked portion is formed around the edge of the interengagement of the brake lever with the connection portion, thereby affixing the brake lever to the camshaft. The caulking can be performed on either the brake lever, the connection portion of the camshaft, or both.
