    摘要： [Problem] To provide a straddle type vehicle provided with a control unit that can improve the riding comfort of a rider and can control the speed change of a continuously variable transmission electronically.
    [Means for Resolution] A straddle type vehicle 1 includes: a driving source (engine) 100 having an output controlled according to an accelerator operating part operated by a rider; a continuously variable transmission 11 connected to the engine 100; and a control unit 120 for controlling the continuously variable transmission electronically. The control unit 120 is characterized by : performing the control of shifting to a kick down mode (50) of shifting a speed change ratio to a lower side than a speed change ratio at the time of a normal mode (60) according to a kick down switch 25 provided separately from an accelerator operating part and operated (42) by the rider; detecting the state of the straddle type vehicle 1 by a sensor 27; issuing a kick down release command according to the state; and performing the control of releasing the kick down mode and returning the kick down mode to the normal mode (60).

    摘要： A shift valve (24) comprises a spool (224) having a downshift position for establishing a lower speed ratio and an upshift position for establishing a higher speed ratio, a plug (225), and a spring (324) between the spool and plug. The spool has a pressure acting area which governor pressure acts on, while the plug has a pressure acting area which throttle pressure acts on. At low throttle pressures, the spool moves from the downshift position to the upshift position when a predetermined vehicle speed is attained. At higher throttle pressures, the spool moves between the downshift and upshift position depending upon the governor pressure and throttle pressure. The shift valve has a port formed therein which admits a downshift position hold signal fluid pressure (i.e., line pressure) between the spool and plug so as to hold the spool to the downshift position thereof.
