Pinion assembly

摘要

A drive pinion assembly 10 for a starter motor has a drive plate 12 adapted to be driven by a shaft of the motor. The drive plate has axially extending projections which co-operate with corresponding projections on a pinion 14. The projections are separated circumferentially by fingers of a resiliently compressible member to reduce impact loading on the pinion 14 as it engages teeth of a ring gear.
