摘要： PROBLEM TO BE SOLVED: To maintain the excellent operability not only by cooling a housing but also by effectively preventing the intrusion of powder and dust into a mounting portion of a guide member.
SOLUTION: Blowing-out ports 42, 42 communicating with the receiving chamber of a fan 17 are formed at a position a little before a flange portion 9 in the neighborhood of the connecting portion of a lower housing 8 with an upper housing 10. Second inlet ports 43, 43 are formed between the front end of the lower housing 8 and the rear end of the guide wall 26 of the upper housing. On the other hand, clearances 44, 44 communicating the right and left blowing-out ports 42, 42 with the second inlet ports 43, 43 are formed between an insulating cover 38 and the lower housing 8. Therefore, an air passage A is formed such that the cooling air discharged from the blowing-out ports 42, 42 moves forward through the clearances 44, 44 between the insulating cover 38 and the lower housing 8 respectively in the state that the insulating cover 38 is mounted, and intrudes into the mounting portion of a guide shoe 29 from the second inlet ports 43, 43 to join again, and then is discharged forward as it is.
