A vehicle approach alert device for a saddle-ridden electric vehicle is a vehicle approach alert device for a saddle-ridden electric vehicle that is provided with a sound emitter that is attached on the vehicle body of a saddle-ridden electric vehicle having an electric motor in a power engine, and that emits an alert sound to a surrounding area for notifying the surrounding area of approach of the saddle-ridden electric vehicle, such that sound emission of the sound emitter is controlled, and the sound emitter is arranged so that the direction of sound emission is oriented diagonally downward and forward of the saddle-ridden electric vehicle.

Vehicle approach alert device for saddle-ridden electric vehicle

Provided is a vehicle approach notification device of a saddle-ridden electric-powered vehicle that outputs a notification sound for notifying the approach of a vehicle. The saddle-ridden electric-powered vehicle includes a front cover that covers the periphery of a head pipe of a vehicle body frame. The sound emission device is located inside the front cover, the front cover has an air opening for taking in air from an outside, and a ventilation passage that is a passage of the air from the air opening and is used for cooling at least one of a power engine of the saddle-ridden electric-powered vehicle and electric components, and the sound emission device is arranged in the ventilation passage.

A two-wheeled motor vehicle () provided with a throttle grip () rotated by the driver to change the degree of opening of a throttle valve (), and also with an exhaust valve () which, when a throttle ratio which is a ratio of the angle of operation of the throttle grip to the maximum rotation angle of the throttle grip is between zero and a predetermined value, reduces noise emitted from an engine.

Two-wheeled motor vehicle

To effectively reduce operational noise generated by vibration of the fuel injection valve with a fuel injection valve installation structure of an engine. In the structure, an installation hole is formed in an engine component member that constitutes a part of an engine. The installation hole has an annular shoulder portion, which is formed in the middle portion thereof, and which faces the exterior side. The fuel injection valve is held between the annular shoulder portion and a supporting member attached to the engine component member. A first damper, with high vibration-damping properties, is set between an annular shoulder portion and a fuel injection valve. A second damper, with high vibration-damping quality, is set between a supporting member and the fuel injection valve.
