An electric vehicle includes a wheel, an electric motor to drive the wheel, a battery to supply electric power to the electric motor, the battery including battery cells and a battery casing to house the battery cells, an onboard charger to charge the battery, the onboard charger being opposed to and spaced apart from an outer surface of the battery casing so that an air flow path exists between the onboard charger and the outer surface of the battery casing, and a cooling fan to generate a flow of air passing through the air flow path between the onboard charger and the battery casing.

Electric vehicle

A motorcycle prevents an increase in air resistance and prevents wind and mud from hitting a rider during travelling of the motorcycle. A side cover of the motorcycle includes a first side cover and a second side cover. The first side cover is disposed laterally outwards of a head pipe and a front fork. The second side cover is disposed laterally outwards of a portion of the first side cover. A lateral end of the second side cover is positioned laterally outwards of the first side cover. A rear edge of the first side cover is at least partially positioned rearwards of a rear edge of the second side cover.

Systems and techniques are described to provide a bulb insertion structure of a vehicular lamp which allows bulb replacement and accurate positioning of a bulb with respect to a reflector. In general, in one implementation, a bulb insertion structure of a vehicular lamp includes a plurality of fixing protrusions formed on an outer periphery of a rear end portion of a cylindrical socket fixture fixed in a bulb insertion hole of a reflector; a plurality of engaging protrusions formed on an outer periphery of a focus ring provided on a bulb and corresponding to the fixing protrusions; and a cup-shaped socket covering the outer periphery of the socket fixture from the rear, the socket incorporating a spring for pressing forward the rear end portion of the accommodated bulb, and having an outer peripheral wall provided with, at multiple locations corresponding to the fixing protrusions, an engaging notch (J-slot) for holding the engaging protrusion and the fixing protrusion overlapped together. In this structure, the J-slot is provided with an engaging recess portion for holding the engaging protrusion in the J-slot when the socket is pulled out from the socket fixture. Furthermore, a slit, which extends continuously from the engaging recess portion of the J-slot in a circumferential direction, is formed of a size that allows the engaging protrusion and the fixing protrusion to only pass therethrough separately.

Bulb insertion structure of vehicular lamp

In a vehicular lamp, a plurality of LED lines to which a plurality of LEDs are connected in series, are connected in parallel. The LEDs are arranged in a flat plane on a circuit board, the plurality of LEDs are arranged symmetrically with respect to a first centerline of the flat plane. Therefore, even when any one of the LEDs in the plurality of the LED lines becomes incapable of emitting light leading to all of the LEDs connected in series in the LED line to turn off, because the LEDs in the LED line are arranged symmetrically, the symmetrical balance of the LEDs shut down is maintained as an entire lamp, and the overall appearance of the lamp can be preserved.
