Abstract
A straddle type vehicle includes a protrusion which is displaced together with a throttle valve, a lever pulley which is displaced in response to the rotation of a throttle grip, a spring and a control device. The spring generates elastic force to return the protrusion to a first original position when the lever pulley is in a second original position. The spring maintains the lever pulley in the second original position by being elastically deformed until the protrusion reaches a predetermined position in which the protrusion is displaced from the first original position in such a direction that the throttle valve opens when the lever pulley is in the second original position. The control device opens the throttle valve by displacing the protrusion until the protrusion reaches the predetermined position in a gear shift change when the throttle grip is fully closed.
