1. the starter motor for internal combustion engine of a compact external electromagnetic switch, including driving axle (1), shift fork (2), an extra shell (3), external electromagnetic switch (5), motor rotary shaft (6), it is characterized in that:

  • also include single retarded device (4) and buffer unit;

    Described single retarded device (4) includes deceleration device and non-return device, and described deceleration device is planetary reducer, including a planetary reduction gear ring gear (4-1) and retardation gear moving axis (4-9);

    Described non-return device includes a single retarded device case (4-5) and friction stopping device;

    A described single retarded device case (4-5) is in tubbiness, and its inwall is provided with a flexible roller groove (4-6), and its outer wall is provided with an extra chuck (4-7);

    A described single retarded device case (4-5) is enclosed within a planetary reduction gear ring gear (4-1);

    Described friction stopping device includes the spring (4-2) and the roller (4-3) that are positioned at a flexible roller groove (4-6);

    Described spring (4-2) one end is against on flexible roller groove (4-6) sidewall, and the other end is by spring base or directly withstands roller (4-3);

    Ramped shaped is made in the bottom of a number flexible roller groove (4-6), and the distance between itself and planetary reduction gear ring gear (4-1) outer wall forms gradual change gap;

    Described buffer unit includes being positioned at a chuck (4-8) of extra shell (3) inwall end, a buffer stopper (4-4) and being positioned at an extra chuck (4-7) of single retarded device case (4-5) outer wall, a described single retarded device case (4-5) is positioned at an extra shell (3), a hole (4-10) on a described buffer stopper (4-4) is enclosed within an extra chuck (4-7), and is positioned between two No. one chuck (4-8);

    Described retardation gear moving axis (4-9) is provided with helical spline (4-11);

    Described driving axle (1) is connected with retardation gear moving axis (4-9) by helical spline (4-11);

    When described spring (4-2) is for flat spring (4-2-1), spring base is flat spring seat (4-2-2);

    When described spring (4-2) is two coil spring (4-2-3), spring base is circle spring abutment (4-2-4);

    Described flat spring seat (4-2-2) is provided with the flat spring chuck (4-2-5) placing flat spring (4-2-1), and makes the arc surface (4-2-6) coordinated with roller (4-3) with the face of roller-contact;

    Described round spring abutment (4-2-4) is provided with the round spring chuck (4-2-7) placing coil spring (4-2-3), and the arc surface (4-2-6) coordinated with roller (4-3) is made in the face contacted with roller (4-3) equally.
