Claims

[Scope of utility model registration request]

Spacers facing each other are arranged at intervals between the rotor windings received on the core holder, and the mutually facing spacers have a shoulder portion on the opposing side surface slightly smaller than the outer diameter surface of the glass bind tape. forming protrusions facing each other so as to protrude outward;
The spacer is tied and fixed together with the rotor winding and the core holder by a sleeve at the top surface excluding the projections, and ventilation holes are provided in the glass bind tape between the mutually opposing projections. A cooling ventilation structure for an end of a rotor winding of a cylindrical alternator.
