A gear retaining mechanism is provided for a transmission comprising a rotary shaft, a hub fixed on the rotary shaft, a clutch slider axially slidably fitted on the hub, and a gear relatively rotatably provided on the rotary shaft. The hub is provided on an outer periphery thereof with a male spline having an axially tapered portion. The clutch slider is provided on an inner periphery thereof with a female spline meshing with the male spline of the hub. The gear is provided on an outer periphery thereof with a male spline to mesh with the female spline of the clutch slider. The male spline of the gear includes an axially tapered portion. The clutch slider is slid along the rotary shaft and located so as to fix the gear to the rotary shaft through the hub so that the female spline meshes with the male spline of the gear.
