Abstract: A travel control device for controlling traveling of a straddle-type vehicle includes a control device, a vehicle speed detector configured to detect a traveling speed of the vehicle, and a vibration detector configured to detect a detection target vibration which is a vibration in a yaw direction or roll direction of the vehicle and has a frequency within a reference frequency range. The control device includes a deceleration device configured to perform a deceleration control to decelerate the traveling speed if the traveling speed exceeds a control start reference speed and an amplitude of the detection target vibration exceeds a control start reference amplitude and a deceleration stop device configured to stop the deceleration control if the traveling speed becomes equal to or less than a target limited speed after the deceleration control is started by the deceleration device.

Abstract: In a variable displacement pump, a pressurizing cylinder is provided on an opposite side of the first fluid pressure chamber, holding the cam ring there between, and a piston inserted to the pressurizing cylinder collides with the cam ring. An oil chamber of the pressurizing cylinder is interposed in a pump discharge side passage, and wherein a pressure in an upstream side of the main throttle provided in the pump discharge side passage is introduced to the first fluid pressure chamber and the oil chamber of the pressurizing cylinder, and a pressure in a downstream side of the main throttle is introduced to the second fluid pressure chamber.

Abstract: In a variable displacement pump, a pressurizing cylinder is provided in an opposite side of the first fluid pressure chamber, holding the cam ring there between, and a piston inserted to the pressurizing cylinder collides with the cam ring. A pressure in an upstream side of both throttle passages comprising the variable throttle passage and the fixed throttle passage provided in the pump discharge side passage is introduced to the first fluid pressure chamber and the oil chamber of the pressurizing cylinder, and a pressure in a downstream side of the both throttle passages is introduced to the second fluid pressure chamber.
