PURPOSE:To incline a thrust piece by a method wherein a spherical part is provided on each thrust piece, a pair of protrusions for a rotary stop is provided by placing the spherical part between them, and one side of the protrusions is covered with a cylindrical weight. CONSTITUTION:A thrust piece 17 possesses a spherical part 18 on its central part of a bearing rest 8 side in a body and a pair of protrusions 19 for a rotary stop having an identical diameter and length on symmetrical positions of both sides of the spherical part in a body. One side of the protrusions 19 is covered by a cylindrical weight 20. Althrough the ptotrusions 19 for the rotary stop are inserted into bearing holes 9 of the bearing rest 8 in a play fit state, the thrust piece 17 is tilted through a weight difference by making the spherical part 18 into a fulcrum as the one side of the protrusions 19 is provided with the weight 20. |
