ASSEMBLING STRUCTURE FOR STATOR SHAFT OF AUTOMOTIVE AUTOMATIC TRANSMISSION

摘要

PURPOSE: An assembling structure of a stator shaft of an automatic transmission for a vehicle is provided to escape to a cut groove which is formed in one end side outer circumference of a large diameter part of the stator shaft, thereby securing a sealing property. CONSTITUTION: A stator shaft(100) is formed with a small diameter part(110) and a large diameter part(120). A serration(121) is formed in other end side circumference of the large diameter part. A cut groove(130) is formed in one end side circumference of the large diameter part. A lateral part(140) is formed between the cut groove and the small diameter part. The lateral part with the shape corresponding to a lateral part of the stator shaft is formed in an inner circumference of an oil pump cover(200).
