To improve winding speed and productivity of a rotating machine by providing curved edges on corner portions of tongues of an insulation cap body. In an insulation cap structure for the rotating machine, corner portions of tongues of an insulation cap body disposed in a stator core or a rotor core is formed so as to have curved edges, and a locus of a needle at the time of winding is close to a circle rather than a rectangle of prior art, whereby winding speed can be increased.
