PURPOSE:To enable to make face fitting of a thrust piece to a thrust disk sufficiently, by a method wherein alignment is made to carry out at two places of a bearing metal and the thrust piece by supporting the thrust piece by the bearing metal inserted in a bearing rest in a taper fit state. CONSTITUTION:A tapered pit 9 is formed on the tip of a bearing rest 8, and a tapered protrusion 11 of a bearing metal 10 is fitted in the pit 9 by keeping a play. Bearing holes 12 and 13 are provided on the bearing rest 8 and the bearing metal 10 respectively, a protrusion 14 for a rotary stop provided on the tapered protrusion 11 of the bearing metal 10 is inserted into the bearing hole 12 in a play fit state and a pair of protrusions 22 for the rotary stop formed on a thrust piece 20 in a body is inserted into the bearing holes 13 in the play fit state. With the above constitution, alignment is done at two places of the bearing metal and the thrust piece, and face fitting of the thrust piece 20 to a thrust disk 18 is done sufficiently. |
