Joint structure for power transmitting member and method for producing the same

A joint structure for a power transmitting member comprising:

• a fiber reinforced plastic tube;
• a joint comprising 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 extending circumferentially around the joint, wherein the joint portion and the sealing portion are disposed in an interior of the tube to be in an assembled state and wherein in the assembled state an outer diameter of the joint portion is larger than an inner diameter of the end portion of the tube;
• and
• an adhesive for sealing between and joining the tube and the joint,
• wherein the adhesive 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, a separation distance between the tapered surface and an inner surface of the tube decreases toward the end of the tube, and the tapered surface is continuously formed around the entire sealing portion.

A joint structure for a power transmitting member comprising:

• a fiber reinforced plastic tube;
• a joint comprising a joint portion for joining to an end portion of the tube, and a sealing portion positioned on an end of the tube side of the joint portion extending circumferentially around the joint, wherein the joint portion and the sealing portion are disposed in an interior of the tube to be in an assembled state and wherein in the assembled state an outer diameter of the joint portion is larger than an inner diameter of the end portion of the tube;
• and
• a liquid packing compound for sealing between the tube and the joint,
• wherein the liquid packing compound fills at least a volume between the sealing portion and the tube, the sealing portion has a tapered surface whose diameter increases toward the end of the tube, the volume has a cross sectional area that decreases toward the end of the tube, and the tapered surface is continuously formed around the entire sealing portion.
