A housing structure for geared motors is disclosed. The housing structure is designed to seal the spaces between a stator core and first and second housings to prevent infiltration of moisture and impurities to a motor's drive part through the spaces or formation and growth of ice on the drive part, thus the motor always being smoothly started in its operation, without having a high drive torque undesirably increased to remove ice or impurities from the drive part. The first housing has a support part functioning to rotatably support a first end of the rotating shaft on the stator core, while the second housing has a cup part functioning to rotatably support a second end of the rotating shaft on the stator core. The support part of the first housing includes a first spherical bearing, a first seat part, and a bearing seat. The first housing also has a cylindrical part assembled with the stator core, and a shaft hole rotatably supporting an output shaft of the motor. The cup part of the second housing includes a main depression, a central bearing seat, a cylindrical second seat part, a chamfered part, a second spherical bearing, a spring-biased support plate, and a cover.
