Claims

[Scope of utility model registration request]

In a manual transmission, the manual transmission has a reverse gear that transmits power via a reverse idler rotatably supported on a reverse idler shaft, and the reverse idler shaft is located at a position where it interferes with gears of other gears. An idler shaft for a manual transmission, wherein at least the portion where the interference occurs is offset from the rest of the shaft.
