An object of the present invention is to provide a saddle-type vehicle which can switch between the parking brake state and the neutral state using a clutch actuator configured to operate the clutch and thus lower the manufacturing cost. According to the present disclosure, there is provided a saddle-type vehicle which can be driven by a driver sitting on a seat and steering a bar handle. The saddle-type vehicle can comprise a clutch arranged on a power transmitting path from a driving source to a wheel (or wheels) configured to selectively transmit a driving power of the driving source to the wheel and selectively cut off the transmission of driving power of the driving source; a transmission arranged on the power transmitting path configured to shift gears in accordance with the travelling state of the vehicle; and a clutch actuator comprising an electrically operated actuator configured to actuate the clutch, wherein the clutch can be switched by the clutch actuator between a parking brake state, in which the power transmission between the driving source and the driving wheel is performed under a stopped state of the driving source, and a neutral state, in which the power transmission between the driving source and the driving wheel is cut off.
