摘要： A fork guide groove of a drum member guides a shift fork so that a shifter member is in a reference position not engaged with first and second speed change members when the drum member is placed in a neutral position, is movable between a first speed-change position engaged with the first speed-change member and the reference position when the drum member is placed in a first operational position, and is movable between a second speed-change position engaged with the second speed-change member and the reference position when the drum member is placed in a second operational position. A slider guide groove of the drum member guides a slider member supported by a fork shaft in an axially movable manner so as not to obstruct movement of the shifter member between the reference position and the first speed-change position when the drum member is placed in the first operational position.

摘要： A shift-drum speed change mechanism includes a first drum spring biasing a first drum toward a first side in an axial direction, which is a side on which a first slider comes into contact with a first speed change member, a first fork spring biasing a first shift fork toward a second side in the axial direction, which is a side opposite to the first side in the axial direction, with a weaker biasing force than the first drum spring, and a first stopper member for the first drum, defining an end of movement of the first drum toward the first side in the axial direction.

摘要： A transmission includes a gear train, a transmission shaft driven by the gear train, a transmission casing incorporating the gear train and the transmission shaft, an axle driven by the gear train, a power take-off (PTO) unit attached to the transmission casing, and a parking brake. The transmission shaft and the axle are extended parallel to each other. The PTO unit includes a PTO input shaft, a PTO shaft, and a PTO drive train transmitting power from the PTO input shaft to the PTO shaft. The PTO input shaft is connected coaxially to the transmission shaft so as to receive power from the transmission shaft. The parking brake is provided on the transmission shaft or the PTO input shaft.

摘要： A power take-off (PTO) unit takes-off power from a transmission for driving a first drive wheel of a vehicle and transmits the taken-off power to a second drive wheel of the vehicle. The PTO unit includes a PTO casing, a PTO shaft and a brake for braking the PTO shaft. The PTO casing is mounted on another casing incorporating the transmission. The PTO shaft is journaled by the PTO casing, drivingly connected to the transmission shaft of the transmission and drivingly connected to the second drive wheel. The brake is disposed in the PTO casing. The brake includes an unslidable pawl that is not slidable axially in the axial direction of the PTO shaft, and includes a slidable pawl that is slidable axially in the axial direction of the PTO shaft so as to selectively engage or disengage with and from the unslidable pawl.
