Front bearing section of housing of combustion engine starter having output pinion

A front bearing section (110) of a starter housing of a combustion engine starter (100) equipped with a starter head (120) including a main body (122) and an output pinion (121), for a motor vehicle, the front bearing section (110) of the starter housing comprising:

• a transverse wall (111) at a front of the front bearing section (110), the transverse wall (111) provided with an opening (112) for the passage of the main body (122) of the starter head (120) there through, the main body (122) axially moveable relative to the front bearing section (110);
• an annular cavity (200) formed in a rear face (400) of the transverse wall (111) at an inner periphery of the transverse wall (111) for mounting an annular seal (240);
• and
• the rear face (400) of the transverse wall (111) configured to form a bearing abutment for an outer ring (231) of a bearing (230);
• the rear face (400) including at least one hollowed-out area (300, 1300) designed to be filled with grease to form a grease supply;
• the hollowed-out area (300, 1300) disposed generally radially outside the annular cavity (200);
• wherein the bearing (230) is sealed, and wherein at least one radial channel (302, 303, 304, 1303) extending radially between the annular cavity (200) and the hollowed-out area (300, 1300) for the grease exists between the hollowed-out area (300, 1300) and a front face of the bearing (230) facing the rear face (400) of the transverse wall (111).
