    摘要: A rotating electric machine comprises a stator and a rotor. In the rotor, numerous slots are formed along a circumferential direction. In the each of slots, a first stator coil and a second stator coil are inserted and insulated by an insulator inserted before inserting the coils in the slots. The insulator encircles the first and second stator coils so as to be formed into an S shape. The center portion thereof extends over the area between the first and second stator coils. One end of the insulator is held between one surface of the center portion of the insulator and the first stator coil. Other end of the insulator is held between another surface of the center portion of the insulator and the second stator coil.

    摘要: There is provided a movable shade which can move between a light shielding position and a light shielding moderating position, so that a single lamp can be used both for low beam and high beam. Then, the longitudinal length of the lamp is shortened so as to attempt to make the lamp compact in size by inserting a light source bulb into a reflector from a side of an optical axis Ax. As this occurs, the insertion and fixing of the light source bulb is implemented at a position which is apart downwardly from the optical axis, whereby the formation of a light source bulb inserting and fixing hole in optical axis sideways areas on a reflecting surface of the reflector is avoided which would otherwise have to occur.
