PCT No. PCT/JP97/00833 Sec. 371 Date Nov. 6, 1997 Sec. 102(e) Date Nov. 6, 1997 PCT Filed Mar. 17, 1997 PCT Pub. No. WO97/36158 PCT Pub. Date Oct. 2, 1997A vehicle propeller shaft and a method thereof has a balancer. The shaft has a slip joint having a first portion with male splines and a second portion with complementary female splines. The male and female splines are joined together with a spline clearance. A first univeral joint member is connected to the first portion of the slip joint and a second univeral joint member is connected to the second portion of the slip joint. The shaft further has first and second connected members each having a flange section. The first connecting member is connected to and extends axially outwardly from the first univeral joint member. The second connecting member is connected to and extends axially outwardly from the second universal joint member. A phase-changing restricting member is fixed at an outer peripheral portion of the slip joint to restrict the change of a locational relative phase between the male and female splines, which change is caused by the spline clearance between the male and female splines. An unbalance correcting member or balancer is fixed to the flange section of at least one of the first and second connecting members to finally balance the propeller shaft.
