摘要： A power transmission shaft has a shaft member having, on an outer peripheral surface thereof, a male spline; a cylindrical member having, on an inner peripheral surface thereof, a female spline; and a seal member provided in a pressed state between an outer peripheral seal surface formed on the outer peripheral surface of the shaft member and an inner peripheral seal surface formed on the inner peripheral surface of the cylindrical member. The cylindrical member is spline-engaged with the shaft member by one end side of the shaft member being inserted into the cylindrical member from an other end side of the cylindrical member. Axial direction shock is absorbed by sliding of the splines. The outer peripheral seal surface is positioned at the other end side with respect to the male spline, and the inner peripheral seal surface is positioned at the other side with respect to the female spline.

摘要： A propeller shaft (1) that is a power transmission shaft has a shaft member (2) as a tubular body made of iron-based metal and a balance weight (3) made of iron-based metal and welded to an outer peripheral surface of this shaft member (2). At least a part of the balance weight (3) of the propeller shaft (1) is covered with a sacrificial metal coating (4) made of sacrificial corrosion prevention material that contains metal whose ionization tendency is higher than that of metal forming the shaft member (2). With this, it is possible to suppress local progression of corrosion at a periphery of the balance weight (3) and improve durability of the propeller shaft (1) .
