摘要： In a vehicle drive transmission device, a transmission includes an intermesh first engagement device, a frictional second engagement device, a first drive device configured to drive the first engagement device, and a second drive device configured to drive the second engagement device. The first drive device includes a first shift drum, a first cam mechanism configured to convert rotational motion of the first shift drum into linear motion, and a first transmission mechanism configured to perform the linear motion. The second drive device includes a second shift drum, a second cam mechanism configured to convert rotational motion of the second shift drum into linear motion, and a second transmission mechanism configured to perform the linear motion. The first shift drum and the second shift drum are connected so as to rotate integrally with each other via a drive shaft. A drum drive source is provided to drive the drive shaft.
