A transmission apparatus includes a plurality of cam grooves on a peripheral surface to move shift forks, a shift cam configured to change a rotation position from a neutral position to a maximum speed position through a first speed position, and a shift mechanism configured to intermittently rotate the shift cam in response to a transmission operation and to hold the shift cam at each position from the neutral position and the first speed position to the maximum speed position. The shift mechanism holds the shift cam at a rotation position in which a rotation angle between the neutral position and the first speed position is the same as a rotation angle between the first speed position and a second speed position, wherein a rotation angle between the maximum speed position and the neutral position is smaller than the rotation angle between the neutral position and the first speed position.
