TRANSMISSION
First Claim
1. A transmission comprising a dissimilar metal joined shaft in which at least a first shaft and a second shaft made of dissimilar materials are joined coaxially, whereinsaid first shaft has a hollow structure and said second shaft is press fitted into said first shaft,an inner circumferential face of said first shaft and an outer circumferential face of said second shaft have an axial overlap section where said first and second shafts overlap each other in an axial direction, andsaid axial overlap section is joined by friction stir welding.

Abstract
A transmission includes a first shaft and a second shaft. The first shaft is made of a first metal material. The first shaft has a hollow structure. The second shaft is made of a second metal material different from the first metal material. The second shaft is fitted into the hollow structure of the first shaft at an axial overlap section. The first shaft and the second shaft are coaxially connected at the axial overlap section with friction stir welding.
