    • PROBLEM TO BE SOLVED: To provide a hydraulic control device for a vehicular continuously variable transmission attaining quick filling of a hydraulic cylinder when a vehicle travels after a long-term stop without impairing the durability of a power transmission member.
      SOLUTION: When the operation of an ignition switch 69 to the ON side is determined by an ignition switch operation determining means 90, an input side hydraulic cylinder 42c is quickly filled with an operating fluid by a quick filling control means 104 based on the determination. Consequently, in comparison with a conventional case of quickly filling the hydraulic cylinder indiscriminately in the state of a vehicle speed being a predetermined value or less or every time the vehicle is stopped, the frequency of quick filling is considerably reduced. The input side hydraulic cylinder 42c is thereby filled quickly when the vehicle travels after the long-term stop without impairing the durability of a transmission belt (the power transmission member) 48.
