Gear-shaped resin sheets Sa are laminated such that tooth portionsare aligned in an axial direction, thereby preparing a spur gear-shaped net-shape body Tooth portions of the resin gear formed in a lower dieare pressed in a helical tooth-shaped molding space to deform the tooth portionsof the net-shape bodyinto a helical tooth tilted relative to the axial direction, and the direction of reinforcement fibers at the tooth portionsof the molded resin gearis tilted relative to the axial direction.

Resin gear, and method and apparatus for producing the same

A resin rotating bodyis configured by a ring-shaped resin ring, and a metallic bushwhich is fitted to an inner circumferential surfaceof the resin ring, and projectionsas rotation preventing means that connects the resin ring and the metallic bush so that the resin ring and the metallic bush do not rotate with respect to each other are provided on an outer circumferential surface of the metallic bush. Projections of the metallic bush are further provided at positions eccentric forward in a press-fitting direction of the metallic bush from a center in the axial direction of the metallic bush.

Resin rotating body and manufacturing method for resin rotating body

The exhaust manifold gasket according to present invention consists of a pair of beaded plates provided with beads extending along the circumferences of exhaust holes therein, and a piled plate assembly inserted between these beaded plates. The piled plate assembly consists of a pair of flat plates, and a refractory sheet member disposed between these flat plates and containing a core plate therein. The refractory sheet member is formed out of a material having a high thermal resistance, excellent heat insulating characteristics and a high compression resiliency at a high temperature, such as a mica material. Accordingly, this exhaust manifold gasket has an improved compression resiliency at a high temperature and an improved sealability at a high temperature, and is capable of properly cutting off the transfer of heat.
