Latest Patents

Eiji Negoro holds a patent for a bearing device that features a dust seal. This dust seal is designed with a tubular fitting portion, a bush end surface abutting portion, a lip portion, and a sealing projection that is integrally formed. The sealing projection is strategically designed to project in an axially opposite direction to the lip portion, ensuring that it effectively overlaps with a chamfered portion of a bush. This design prevents lubricant from entering between the bush and the dust seal's end surface, thereby maintaining a sealed state. As a result, the dust seal is stably held on the inner peripheral side of a boss member, which prevents it from being pulled out.
