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.

    一种用于传动轴(1)的管体(2),其中传动轴(1)由纤维增强塑料制成。管体(2)具有筒状的主体部(10)、与主体部(10)相比直径缩小且用于接合短轴(4)的第二连接部(30)、外径随着从主体部(10)靠向第二连接部(30)而缩小的倾斜部(40)。在倾斜部(40)上形成有脆弱部(50),当沿轴线方向输入的载荷超过规定值时所述脆弱部破损。在该结构中,能实现管体(2)的低成本化,并且当规定的载荷沿轴线方向输入管体(2)时管体(2)可靠地破损。
