PROBLEM TO BE SOLVED: To prolong the service life of a bearing by prolonging the lubricating period of the bearing by one-side mounting at the time of mounting a fan blade on a motor base and, at the same time, forming an oil storage space. SOLUTION: As the structure of an oil storage bearing mounted on a motor base 5 having a recessed section, a rotating shaft 13 having a recessed groove at its front end and a sleeve 2 the lower section of which is arranged in the recessed section of the motor base 5 and which has a locking section 21 which is locked to the recessed groove of the rotating shaft 13 for improving the effect of one-side mounting when the rotating shaft 13 is attached in the sleeve 2 are provided. In addition, a bearing 3 which is arranged in the sleeve 2 in such a way that the bearing 3 is supported on the locking section 21 and can store a prescribed amount of lubricating oil in an oil storage space 6 formed between the outer peripheral surface of the bearing 3 and the inner peripheral surface of the sleeve 2 so that the rotating shaft 13 may be replenished with the lubricating oil when the shaft 13 is rotated is provided.
