Abstract
A tube is used in fiber-reinforced plastic power transmission shaft. The tube comprises: a cylindrical body section; a connection portion that has a larger diameter than the body section; and an inclined portion that has an outer diameter that increases toward the second connection section from the main body part. The inclined section has formed thereon, a weak section that is damaged when a load input in the axial direction exceeds a prescribed value. With this configuration, the cost of the tube can be reduced, and when a prescribed load is input to the tube in the axial direction, the tube is reliably damaged.
