To provide a control device of a power transmission device for the hybrid vehicle that can start the engine in the state where the lubricating oil is spread in the friction type torque limiter.

The increase of limit torque Tlim of the torque limiter 22 at engine start-up can be controlled since an oil pump 24 is driven and torque limiter 22 is lubricated before the engine start-up. Therefore, since the torque limiter 22 slips even if an excessive torque is transmitted at the engine start-up by desired limit torque Tlim, the increase of the load that relates the rotary shaft and a bearing is controlled. Thereby, strength of the rotary shaft and the bearing from this need not be raised in excess, and as a result, weight increase and upsizing of the rotary shaft and the bearing can be controlled.
