- This pad is configured at its inner periphery to cooperate with the outer periphery of the yoke 15, which is thus devoid of indentation at this level and has a simple shape.
- the starter support 16 is thus simplified with respect to that of the documents FR-A-2787833 and FR-A-2767157, since it does not require specific ribs or grooves for the rotational stop of the ring gear 46. the absence of ribs or other raised protuberances inside the starter support 16 frees up the available space for accommodating larger components, for example a larger diameter launcher 30.
- FIG. 10 shows the device for positioning the ring 46 of the gearbox 45 relative to the support 16 of the starter and the cylinder head 15 of the electric motor 11.
- the ring 46 has at its projecting outer periphery a collar 73 having a first bearing surface 70 located in the same plane as the second bearing surface 71 of the starter support 16, and the third bearing face 72 of the yoke 15 of the inductor.
- the flange 73 is axially offset relative to the bottom 62 as can be seen more clearly in FIGS. 2 and 6.

- the flange 73 is extended towards the rear, in the direction opposite to the lever 41, by a network of ribs 402 of axial orientation of different length. These ribs, distributed circumferentially, reinforce the skirt 61. It can be seen in FIG. 2 that the outer periphery of the front section of the skirt 61, extending between the flange 62 and the bearing face 70 of the collar 73, presents pointed projections 400. Similarly, we see in 401 sharp projections, which extend to the outer periphery of the ribs 402 as best seen in Figure 8. Thus it is easy to clamp the front section in the first housing of the support and even we force the breech on the ribs 402. This is made easy thanks to the projections 400, 401, which contribute to the rotational locking of the crown and the cylinder head 15.
- the latter is obtained by a form pressed into the cylinder head 15, and abutting against the skirt 61 opposite the flange 73.
- the boss comes into abutment on the skirt 61 via a radial flange of a metal piece 100 called a dust cover axially wedged on the free end of the skirt in favor of a shoulder (not referenced). of it.

- the tabs 55 and the tabs 64a, 64b of the yoke 64 provide between them a space for the passage of the control lever 41, here plastic.
- the tabs 55 correspond to the tabs 64a, 64b of the yoke 64 with only one bearing 56.
- the lever 41 is connected to the movable core 40 via a rod hitched elastically to the movable core 40 as partially visible in Figure 1, and better visible in Figure 2 of the document FR-A-2787833.
- the fork 60 has at its lower end two fingers penetrating into a groove in the driver 51, one of the sides of the groove being formed by a washer mounted snap on the coach, as described in FR-A-2687736.
- the cylindrical cylinder head 15 like the tank 33, has a simplified structure thanks to the invention, since the ring 46 has an extension, here having a generally transverse orientation. This extension extends substantially in the extension of the flange 62 of the ring 46 of hollow form, serving as housing the speed reducer epicyclic train.
- the spindle 54 is molded with the lever 14 and, as shown in FIG. 11, a single tongue 55 of transverse orientation directed towards the contactor and having at its outer periphery a recess of FIG. receiving 155 of the pivot axis 54 of cylindrical shape.
- the tongue 155 is therefore of reduced thickness at its recess 155 generally of rectangular shape and opening to the outer periphery of the tongue 55 generally of rectangular shape.
- the bottom 159 of the recess 155 constitutes a shoulder for the axis 54 and advantageously has a rounded profile.
- This axis 54 is here of the type shown in FIG. 4 and therefore comprises two cylindrical studs or trunnions extending on either side of the body of the lever 41.
- the pads of the axis 54 are each delimited by a plane face of transverse orientation, unlike the pads of the axis 54 of FIG. are delimited by an inclined face for spacing the legs of Figure 4.
- the width of the recess 155, made in the rear face of the tongue 55 facing the support 16, is greater than the length of the axis 54.
- the height of this hollow is greater than the diameter of the axis 54.
- the recess 155 centrally has a reduction in thickness 156, which thus delimits two spans 157 extending on either side of the reduction in thickness 156. These spans 157 are spans for the spikes of the spine. pivot axis 54.
- the thickness reduction 156 avoids interference with the body of the lever 41.
- the rounded profile of the bottom 159 is dimensioned as a function of the diameter of the studs of the axis 54.
- the advantage of such an assembly avoids the use of an insert to achieve the bearing surface and articulation of the lever 41, and further simplifies the machining operations for maintaining play free parts to assemble because the recess is easier to achieve than the or bearings 56.
- a tab 55 robust and wide.
- the bottom 59 forms in connection with the seats 157 a cradle for the axis of the lever 41 and therefore a bearing surface therefor.
- the width of this tongue 55 is dimensioned according to the cavity 69 of FIG. 8.
- the lateral edges 210 of the tongue 55 are adapted to cooperate in a complementary manner with the lateral edges 169 (FIG. 8) delimiting the cavity 69 for blocking or immobilization in rotation of the crown 46.
- the tongue 55 has been rigidified centrally.
- a central opening 210 centrally affecting the bottom 159 at the reduction of thickness 156 of the recess 155.
