Abstract
To provide the breather structure of a shaft-drive-type drive device which can miniaturize a gear casing as a whole and can exhibit an excellent appearance. A shaft-drive-type drive device is capable of transmitting an output of an engine mounted on a vehicle body to a wheel by way of a drive shaft by connecting one end of the drive shaft to an output shaft of the engine by way of a universal joint and by connecting the wheel to another end side of the drive shaft by way of gears or the like. A breather mechanism, which performs a breathing operation of the inside of a gear casing housing the gears or the like, is mounted on the gear casing, and an atmosphere opening portion of the breather mechanism is formed to open upwardly in the vertical direction of a vehicle and inwardly in the width direction of the vehicle.
