Abstract:
PROBLEM TO BE SOLVED: To provide a small-sized motor for cooling fan or the like that is capable of lasting long time at high temperature, even though the motor is of small and thin type.
SOLUTION: A small-sized motor has a lubricating oil replenishing member 9 installed at a sliding bearing 8 that rotatably supports a rotary shaft 7. A thrust pipe 12 that splashes lubricating oil outward is installed at an end of the rotary shaft 7, and a shield piece 13 part of which is shaped so as to cover the thrust pipe 12 is secured on a bearing support cylinder 2. A groove 14 for returning the lubricating oil is formed on the circumference of the sliding bearing 8. Thus it is possible to obtain a small-sized motor that allows the lubricating oil to be collected and has a long life time.
