A method for manufacturing a bearing mechanism includes the steps of: (a) setting a position of an annular member relative to a center axis; (b) moving the annular member toward an opening of a sleeve housing through a shaft by pressing and elastically deforming a bottom portion of the sleeve housing; (c) releasing the pressing to restore the bottom portion to its original shape; and (d) fixing the annular member to the sleeve housing. Herein, the step (b) is performed by arranging the annular member within the sleeve housing, making one end portion of the shaft received in the annular member contact an inner bottom surface of the sleeve housing or with a thrust member disposed thereon, and making the annular member contact the shaft in a direction leading from the opening to the bottom portion of the sleeve housing.
