Title:
TUBE USED IN POWER TRANSMISSION SHAFT AND POWER TRANSMISSION SHAFT
Document Type and Number:
WIPO Patent Application WO/2020/174691
Kind Code:
A1
Abstract:
A tube (2) is used in fiber-reinforced plastic power transmission shaft (1). The tube (2) comprises: a cylindrical body section (10); a second connection section (30) that has a smaller diameter than the body section (10) and is connected to a stub shaft (4); and an inclined section (40) that has an outer diameter that decreases toward the second connection section (30) from the main body part (10). The inclined section (40) has formed thereon, a fragile section (50) that is damaged when a load input in the axial direction exceeds a prescribed value. With this configuration, the cost of the tube (2) can be reduced, and when a prescribed load is input to the tube (2) in the axial direction, the tube (2) is reliably damaged.
