US 7,062,835 B2 · Joint structure for power transmitting member and method for producing the same

Abstract

A joint structure for a power transmitting member includes a fiber reinforced plastic and a joint. The joint includes a joint portion for joining to an end portion of the tube, and a sealing portion formed on an end of the tube side of the joint portion. The joint portion and the sealing portion are disposed in an interior of the tube. A liquid packing compound is provided for sealing the tube and the joint. The liquid packing compound fills at least an area between the sealing portion and the tube. The sealing portion has a tapered surface, whose diameter increases toward the end of the tube. Thereby, when the joint portion is joined to the end of the tube, a clearance between the tube and the joint portion is entirely filled with the liquid packing compound.
