An assistive power control apparatus for a motor-assisted bicycle controls a motor to generate an assistive torque depending on the pedaling force of a rider. The assistive power control apparatus detects a rotating torque value of a crankshaft rotated when a rider steps on pedals by a torque sensor, controls a motor to generate an assistive power determined using the rotating torque value, calculates a rotation angle of the crankshaft when a present rotating torque value is detected from a time period from a timing of detection of a peak position of the rotating torque value to a timing of detection of the rotating torque value, calculates a pedaling force applied when the rider steps on the pedals from the calculated rotation angle of the crankshaft and the detected present rotating torque value, and determines the assistive power of the motor according to the calculated pedaling force.

A saddle-ride three-wheeled vehicle has a fuel cell which generates an electric power by a chemical reaction between a fuel gas and a reaction gas. The three-wheeled vehicle includes a drain pipe which guides water discharged from the fuel cell out of a vehicle body; a rear body to which a pair of left and right rear wheels are journaled; and a linking mechanism which swingably links the rear body and a front body to allow the front body to sway left and right with respect to the rear body, wherein the drain pipe has a drain port between the pair of left and right rear wheels.

A pressure difference rearward of a windshield is efficiently corrected in a windshield unit for a saddle-ride type vehicle provided with two types of air ducts for directing the air flow from the front of the vehicle to the upside of the vehicle and to the rear of the windshield. A windshield unit includes an air duct for allowing an air introduction port opening toward the front of the vehicle to communicate with an air blowout port opening toward the upside of the vehicle and a second air duct for allowing a second air introduction port opening toward the front of the vehicle to communicate with a second air blowout port disposed rearward of the air duct to open toward the rear of the vehicle. The second air blowout port is disposed within the left-right width of the air blowout port of the air duct.
