A straddle-type electric vehicle, comprising a pair of left and right main frames, a seat rail extending rearward from a rear portion of each of the main frames, a pivot frame extending downward from a rear portion of each of the main frames, a swing arm supported by the pivot frame, a battery arranged in a space between the main frames, a power unit arranged in the space, a wind guiding duct for guiding traveling wind to the space, and an air outlet port for emitting the traveling wind, the air outlet port being provided so as to be capable of emitting the traveling wind inside the wind guiding duct from a lower portion of a vehicle body to an area below the vehicle body.

Straddle-type electric vehicle

A straddle-type electric vehicle, comprising a pair of left and right main frames, a seat rail extending rearward from a rear portion of each of the main frames, a pivot frame extending downward from a rear portion of each of the main frames, a swing arm supported by the pivot frame and by which a rear wheel is swingably supported, a battery arranged in a space between the main frames, a power unit arranged in the space and generates motive power based on electric power of the battery, and a wind guiding duct for guiding traveling wind to the space, the wind guiding duct provided relative to each of the main frames, the wind guiding duct being positioned more outward in a vehicle width direction than the main frames.

In an internal combustion engine including a driving-sprocket cam chain guidefor guiding a cam chainalong a driving sprocket, as viewed in a crankshaft axial direction, a guide bodyof the driving-sprocket cam chain guideextends beyond a winding termination point P of the cam chainon the driving sprocketto a position adjacent to a chain moving surfaceof a cam chain tensioner, on which the cam chainslides. The engine provides a cam-chain dropout preventing function to the cam chain guide, thus reducing load on the cam chain tensioner and improving durability of the tensioner lifter.
