SEAL STRUCTURE OF MOTOR CASE

摘要

PROBLEM TO BE SOLVED: To provide a seal structure of a motor case, which can improve motor efficiency by reducing a loss by sealing a lead wire connection part of the motor case housing a motor for rotatively driving an impeller by a simple configuration.SOLUTION: A connector insertion hole 10, into which a connector 9 is inserted and exposed outside a case, is formed in a motor case 6. An annular seal material 12 fitted into the outer periphery of the connector 9 is sandwiched between a motor board 8 and a bottom part of the motor case 6 so that the connector insertion hole 10 can be sealed.
