PROBLEM TO BE SOLVED: To provide a bearing fixing structure to implement high thrust load resistance at low cost, in place of a conventional locating snap ring. SOLUTION: A pin fitting hole 2 is formed in a shaft 1 to passing through the shaft 1 in a diameter direction. A pin 3 is pressed into the pin fitting hole 2 so that both ends 3a of the pin project from an outer face of the shaft 1. An inner ring 5 of a bearing 4 is fitted on an outer circumferential face of the shaft 1, and a width surface of the inner ring 5 is engaged with the both ends 3a of the pin 3 projecting from the shaft 1. For a pin 3, for example, a split-cylinder-shaped spring pin is used.
