Drive device for hybrid vehicle and case for the same

A drive device for a hybrid vehicle, comprising:

• an input shaft rotatably connected to an engine;
• a motor having a rotor and a stator;
• an output shaft arranged on a rotation axis in a coaxial manner with the rotor so as to be integrally connected to the rotor as a unit and configured so as to be engaged with and disengaged from the input shaft;
• a rotation angle sensor detecting a rotation angle of the rotor, the rotation angle sensor including a rotating portion, which is provided at the rotor so as to rotate together with the rotor as a unit, and a fixed portion, which is provided so as not to rotate and which forms an angle relative to the rotating portion;
• a case rotatably and axially supporting the input shaft and the output shaft on the rotation axis and accommodating the motor and the rotation angle sensor wherein
• a side wall portion of the case, which extends in a direction orthogonal to the rotation axis, includes an angle adjusting member supporting the fixed portion of the rotation angle sensor in a coaxial manner relative to the rotation axis while allowing the angle of the fixed portion to be adjustable, and a clamp member supporting a harness, which is connected to the fixed portion of the rotation angle sensor, while allowing the harness to be movable;
• wherein the case is formed by casting, a casting surface of the case facing the clamp member is processed to be smooth, and the harness is positioned between the clamp member and the smoothly processed surface of the case, so that the harness is supported by the clamp member and the smoothly processed surface of the case while allowing the harness to be movable;
• and
• the clamp member includes a parallel portion extending in a longitudinal direction of the clamp member so as to be parallel with the side wall portion and curved portions, which are obtained by curving respective side end portions of the parallel portion in a width direction thereof so as to extend away from the side wall portion, and the clamp member is arranged so that the longitudinal direction thereof extends orthogonally to the harness.
