A vehicle manual transmission includes: shift fork shafts (34a, 34b, 34c); shift forks (35a, 35b, 35c); sleeves (48a, 48b, 48c); and gear pieces (30a, 30b, 30c, 30d, 30e). Each of the shift forks (35a, 35b, 35c) is coupled with the shift fork shaft (34a, 34b, 34c) so as to be moved together. Each of the sleeves (48a, 48b, 48c) has an annular shape. The sleeve (48a, 48b, 48c) includes an annular sliding groove to be fitted to the shift fork (35a, 35b, 35c) on an outer peripheral surface of the sleeve (48a, 48b, 48c). The sleeve (48a, 48b, 48c) includes peripheral edges forming annular planes as viewed in the longitudinal direction of the shift fork shaft (34a, 34b, 34c). Each of the gear pieces (30a, 30b, 30c, 30d, 30e) includes outer peripheral teeth to be meshed with inner peripheral teeth formed on an inner peripheral surface of the sleeve (48a, 48b, 48c) when the sleeve (48a, 48b, 48c) is moved in accordance with the gear shift operation. The shift fork shaft (34a, 34b, 34c) or the shift fork (35a, 35b, 35c) includes a restricting member (66, 84,106, 126) that abuts to the peripheral edge so as to restrict a movement of the sleeve (48a, 48b, 48c) in a longitudinal direction.
