PROBLEM TO BE SOLVED: To obtain a structure of a blower in which the engagement of a claw part is performed without causing the deformation of the metal-made claw part when connecting a cover formed of a metal plate having the claw part to a casing main body.SOLUTION: A blower comprises a casing main body 20, and a cover 40 which covers an opening of the casing main body 20. The casing main body 20 has a protrusion 51 arranged at its external periphery, and a guide part 52 which is separated from the protrusion 51 to the circumferential direction, and the cover 40 has a root part 54 which extends to the axial direction from it edge, and a claw part 55 which extends to the circumferential direction, and is not constricted at its tip. In a state that the root part 54 is engaged with the guide part 52, the claw part 55 straddles the protrusion 51 while being elastically deformed, and the engagement of the claw part 55 with the protrusion 51 is performed. |
