A method for manufacturing a vehicle in which a projected part formed on an assembly surface of one component and a recessed part formed on an assembly surface of the other component are fitted to each other so that the one component and the other component are assembled together is provided. A barb structure protruding outward and towards the root side of the projected part is formed on an outer circumferential surface of the projected part. Alternatively, a barb structure protruding inward and towards the root side of the recessed part is formed on an inner circumferential surface of the projected part and a groove into which the barb structure fits is formed on an outer circumferential surface of the projected part.

A system for installing hose couplings includes a motor, a drive shaft extending along and axis and powered about the axis by the motor, and a tool rotationally coupled to the drive shaft. The tool includes a hub and two arms extending outward from the hub and defining respective load surfaces such that both arms may tangentially abut a respective hook of a quick coupling for a blast hose when the quick coupling is aligned on the axis.

A rotor according to an embodiment includes a cylindrical magnet, a holder, and a balance adjusting portion. The cylindrical magnet has a bore portion into which a rotary shaft is inserted, the inner diameter of the bore portion being larger than the outer diameter of the rotary shaft. The holder is made of resin, and has a tubular portion formed in the bore portion of the magnet and a protruding portion protruding from the magnet in the rotation axis direction, the holder being press-fitted onto the rotary shaft. The balance adjusting portion is press-fitted onto the rotary shaft with the protruding portion interposed therebetween.
