1. A straddle type vehicle, comprising:

  • a throttle valve for adjusting the amount of air intake of an engine;

    an acceleration controller for opening and closing the throttle valve and configured for operation by a rider;

    an electric motor for actuating the throttle valve;

    a first member displaced together with the throttle valve, the first member having a first original position when the throttle valve is fully closed;

    a second member displaced in response to the acceleration controller, the second member having a second original position when the acceleration controller is fully closed;

    an elastic body interposed between the first member and the second member when at least the first member and the second member are in the first original position and the second original position, respectively, the elastic body generating a restoring force to return the first member to the first original position when the second member is in the second original position, and maintaining the second member in the second original position by being elastically deformed until the first member reaches a predetermined position when the first member is displaced from the first original position to a direction in which the throttle valve opens in a state in which the second member is in the second original position; and

    a control device responsive to a predetermined control signal, the control device being configured to open the throttle valve by driving the electric motor and displacing the first member until the first member reaches at most the predetermined position in response to the predetermined control signal.
