Rainwater or car wash water that has entered travels along the inner surface of the cover to the meter side.
The flow can be prevented by the rib 36a.
Thus, it is possible to prevent the meter unit 38 from being splashed with water.
As a result, the glass 38b of the meter unit 38 became cloudy.
Or the occurrence of rust in the meter unit 38
Can be prevented. By the way, vent the meter case 38a.
Water (not shown) for car washing
When it directly touches the meter unit 38, it enters through the above-mentioned pores.
Glass 38b may be fogged by the water
Was. A rib 36a is formed in the opening 35a.
It is difficult to see the meta case 38a from the side of the vehicle
And appearance deterioration can be prevented. In the present embodiment, the rib 36a is connected to the front cover.
Since it was formed integrally with the bar 36, a rubber plate was
The cost can be reduced compared to the case of attaching
Workability can be improved by reducing the number of attachment steps. The projecting height of the rib 36a is set on the design surface.
The ribs 36a are formed because they are set to the extent that sink marks do not occur.
Deterioration of the appearance due to this can be prevented. In the above embodiment, the front cover
Of a scooter with a headlight 29 at the front end of the
