PURPOSE:To facilitate alignment of a female hole, and a bolt hole and mounting of the bolt by providing such an arrangement that a bearing is fitted in its own position and also a positioning pin is inserted therein so that the female hold of a bearing fixing plate may coincide with the bolt hole of a easing. CONSTITUTION:A concave part 12 having inner diameter capable of positioning a bearing 70 in by matching its outer diameter port in the concave part 12, a positioning pin 22, and a female hole 14 in which a fixing bolt 18 can be screwed are provided on a bearing fixing plate 10 and a positioning hole 20 in which the positioning pin 22 is fitted, and the bolt hole 16 for allowing penetration of the bolt 18 are provided in a casing 74. Then, such an arrangement is provided that the position of the female hole 14 of the bearing fixing plate 10 may coincide with the position of the bolt hole 16 of the casing 74 in such a condition for allowing insertion of the positioning pin 22 into the positioning hole 20 of the casing 74 as well as the outer diameter part of the bearing 70 is fitted in the concave part 12. |
