<p>PROBLEM TO BE SOLVED: To provide a bearing fixing structure capable of easily mounting a bearing to a housing, while reducing space without degrading the accuracy of a bearing hole. SOLUTION: A bearing hole 1a is formed on a housing 1 and one of snap grooves 1b eccentric to the bearing hole 1a is formed around the bearing hole 1a. In assembling of a bearing, the bearing 2 is inserted into the bearing hole 1a, in a state with a snap ring 3 being embedded in the housing side snap groove 1b, a bolt 4 fitted in the housing 1 is fastened, an intermediate outer peripheral part of the snap ring 3 is pressed in a state that the other snap groove 2b formed on the bearing 2 is opposite to the snap groove 1b, and the snap ring 3 is compressed toward its center direction. Whereby the outer peripheral part of the snap ring 3 is engaged with the eccentric snap groove 1b at housing side, and the inner peripheral part is fitted in the snap groove 2b at bearing side formed on the bearing 2 to complete the assembling of the bearing.</p> |
