PROBLEM TO BE SOLVED: To provide a control device for a power transmission mechanism for controlling the deceleration of a vehicle by controlling the amount or temperature of lubricating oil to be supplied to the power transmission mechanism which performs shift transmission of power generated by a driving force source. SOLUTION: When the vehicle Ve travels while being decelerated by travelling inertial force, power transmission efficiencyη' of an automatic transmission mechanism 2 is controlled to control the deceleration of the vehicle Ve by controlling the amount or temperature of lubricating oil to be supplied to the automatic transmission mechanism 2 which performs shift transmission of power generated by an engine 1. Since the power transmission efficiencyη' of the automatic transmission mechanism 2 is controlled by controlling the amount or temperature of lubricating oil to be supplied to the automatic transmission mechanism 2, an optional deceleration can be obtained.
