SUBMERGED MOTOR

PROBLEM TO BE SOLVED: To provide a submerged motor which is hard for air to remain in a liquid reservoir part in the case of sealing a sealant, capable of holding good lubricating condition on a bearing part. SOLUTION: In this motor, a space part 8e as a liquid reservoir part having an almost spherical inner surface is formed in the periphery of a rotor shaft positioned in a load side from a boss part 8a which fit-mounts a sleeve bearing 9 in the internal periphery of a load side bracket 8A, also an air bleeding through-hole 8c inserted from the space part 8e to outside a load side end part in the load side bracket 8A is formed. In this way, a sealant 16 can be fully filled so as to prevent air from remaining in the space part 8, the possibility of dry operation of the sleeve bearing 9 is lessened, and good lubricating condition can be maintained.
