Abstract
In a starter for an internal combustion engine, comprising: a pinion; shift mechanism for moving the pinion into mesh with a ring gear of the engine; a housing for accommodating the pinion and the shift mechanism; an electric motor for rotating the pinion; a substantially cylindrical motor casing for accommodating the electric motor; a contact unit for selectively providing electric power to the electric motor; a brush holder stay disposed between the housing and the motor casing, the brush holder stay having a cavity opened toward the motor casing and the contact unit being mounted in the cavity; and a cover for covering the cavity of the brush holder stay, the cover is made of a flexible member so that the cover is naturally curved, and the cover is disposed between the brush holder stay and the motor casing with its concave surface facing the brush holder stay so that the cover is pushed toward the brush holder stay by an axial end of the motor casing. Thus, when pressed against the brush holder stay by the motor casing, the cover is deformed and made straight to produce a resilient restoring force, whereby increasing the pressing force to ensure sufficient watertight sealing ef…
