Latest Patents
Naoto Oono holds a patent for a one-way clutch. This invention involves an assembly where a sprag is temporarily attached to a retainer by a return spring. The design ensures that even if the sprag projecting from the retainer is depressed, it is prevented from dropping out by a retaining member of a friction plate fixed to the end portion of the retainer. A lubrication passage is strategically formed by opening a space surrounded by the outer race, retainer, and sprag to the outer peripheral side. The attaching member of the friction plate, which is fixed to the retainer by spot welding, is recessed backward in a downward stairway manner for a contact surface. This design prevents any rise in the attaching member from coming into contact with the contact surface. Additionally, a corner edge is formed in a spherical shape to ensure that when the corner edge of each frictional member drops into a rivet hole of the attaching surface, it does not thrust into the periphery of the hole upon exiting.
