Abstract
A drive device for a hybrid vehicle, the drive device includes: an input shaft and an output shaft, which are supported by a case to be rotatable around a rotation-axis; a motor, which includes a rotor integrally coupled with the output shaft and a stator fixed to the case; an input-side rotation member and an output-side rotation member, which have an annular shape; a rotation angle sensor, which detects a rotation angle of the rotor, wherein the rotation angle sensor includes: a rotating sensor member coupled with the output-side rotation member; and a fixed sensor member fixed to the case to detect an angle between the rotating sensor member and the fixed sensor member; a protrusion, which protrudes in a radial direction; a groove to receive the protrusion to be inserted; and a restriction portion, which restricts relative rotation between the rotating sensor member and the output-side rotation member.
