PURPOSE:To eliminate check and maintenance of a warren motor by mounting a pipe through one side wall of a cover, and forming an air passage which reaches the interior. CONSTITUTION:The output shaft 15 of a warren motor is supported by a bearing 18, which is secured to one side wall 8a of the cover 8. The cover 8 is mounted at the end face to a supporting plate 17, and the motor is secured. A gap 21 is formed between the wall 8a and the plate 17, and a hole 22 is provided between the plate 17 and the bearing 18. When an AC voltage is applied to a coil 6, a rotor 9 rotates synchronously with power source frequency, and this rotary force is transmitted to the shaft 15. In this case, a cylindrical pipe 15 formed with a collar at one end is inserted via through holes 26 formed at the wall 8a and a group plate 13 into the mounting hole 27 of the wall 8a. In this manner, an air passage C which is fed through the pipe 25 to the interior of the cover 8 is formed. |
