Support structure for pinion pusher of starter for internal combustion engine
First Claim
Patent Images
1. A starter for an internal combustion engine comprising:
- a housing;
a spline tube disposed within said housing, said spline tube having a spline formed in an inner periphery thereof;
at least two bearings working to support an outer periphery of said spline tube;
a starter output shaft having a spline which is slidable engagement with the spline of said spline turbe, said starter output shaft having a pinion which is provided on an end portion of said starter output shaft cantilevered by one of said bearings and which works to mesh with a ring gear of an engine for outputting torque produced by a motor to start the engine;
at least one elongated hole formed in said spline tube;
an engagement member engaging said starter output shaft through said elongated hole of said spline tube; and
a pinion moving mechanism responsive to activation of the starter to push said engagement member for moving said pinion toward the ring gear along with movement of said engagement member along said elongated hole.

Abstract
A starter for automotive internal combustion engines is provided which includes a starter output shaft with a pinion which establishes engagement with a ring gear of the engine and a spline tube. The starter output shaft is disposed within the spline tube in splined engagement therewith. The spline tube is supported firmly by a housing through at least two bearings, thereby avoiding precession or wrenching of a pinion-mounted portion of the starter output shaft projecting from the housing about an outside one of the bearings.
