<P>PROBLEM TO BE SOLVED: To provide an electric motor with sealing means capable of reducing the number of components and the number of man-hours for blocking a hole used in an airtight test by providing an oil seal mounted to the electric motor with a function for sealing an output shaft part, and a function for blocking the hole used in the airtight test at the same time of mounting the oil seal to the electric motor. <P>SOLUTION: A state (a) before an oil seal 50 is mounted to a housing 12 of a motor, and a state (b) after the oil seal 50 is mounted to the housing 12 are explained. The oil seal 50 is mounted to the housing 12 to block a hole 12c for a motor airtight test with a columnar protrusion 52 of the oil seal 50. By using the oil seal 50 having a local columnar protrusion 52 that can block the hole (12c) for the housing 12 having the hole 12c for the motor airtight test, the hole 12c for the motor airtight test is blocked at the same time of mounting the oil seal 50 to the housing 12. <P>COPYRIGHT: (C)2013,JPO&INPIT |
