Abstract

In an engine starter, to facilitate the assembling of a solenoid assembly, an annular outer peripheral wall is formed in the casing for receiving the energization solenoid assembly and to secure the solenoid assembly by crimping a free end of the annular outer peripheral wall onto an axial end of the solenoid assembly, and the energization solenoid assembly is fitted into the bore defined by the annular outer peripheral wall by engaging the outer periphery of the solenoid assembly with three fingers of an assembly tool. A plurality of crimping portions are defined by a plurality of recesses provided along the circumferential direction of the free end of the annular outer peripheral wall so that the fingers of an assembling tool when inserting the solenoid assembly are not interfered by the annular outer peripheral wall.

Dependent claims

In an engine starter comprising an electric motor, a pinion casing attached to an axial end of said electric motor, and an annular cylindrical solenoid assembly fitted in said pinion casing;

said pinion casing, comprising:
an open end adapted to be attached to said electric motor;
an annular wall having a base end secured to said pinion casing and a free end extending axially toward said electric motor, said annular wall defining an inner bore receiving said solenoid assembly;
and
stopper means for limiting movement of said solenoid assembly away from said open end of said pinion casing;
wherein the free end of said annular wall is provided with a plurality of crimping portions separated by a plurality of recesses, said recesses extending along a portion of said inner bore in a direction of an axis of said inner bore said crimping portions of said free end of said annular wall being at least partly crimped onto an axial end of said solenoid assembly facing said open end of said pinion casing.
