Abstract

PURPOSE:T prevent the turbulence of an air passage and suppress a lowering of performance and noise by providing a punch hole on a ring wall to which a casing is fitted, and forming a protruding part in the position corresponding to the punch hole on the outer circumferential end of an air guide. CONSTITUTION:On the outer circumference of an anti-load bracket 6, a ring wall 6a for fitting a casing 9 is formed, and the ring wall 6a has a punch hole 6b. On the outer circumferential end 11b of an air guide 11, a protruding part 11c is formed in the position corresponding to the punch hole 6b. On the outer circumference of the casing 9, a punch part 9a is formed in conformation to the punch hole 6b to prevent the falling-out. Since the protruding part 11c is formed on the outer circumferential end 11b of the air guide 11, the punch hole 6b of the anti-load side bracket 6 is shielded by the protruding part 11c, and the air passage 10 of the air guide 11 is smoothed to prevent the turbulence of air, and a reduction in performance and noise can be suppressed.
