Abstract

In an air cleaner unit having a casing body of carbon fiber and configured to introduce outside air into an engine, a lamination layer part formed by laminating plural kinds of materials is arranged in a region of at least a portion of the air cleaner unit. The lamination layer part is formed of a carbon fiber layer and an elastic material layer. The casing body is provided with an opening to be connected to an air intake duct. The lamination layer part is formed of a first lamination layer part and a second lamination layer part of which the elastic material layer is thicker than that of the first lamination layer part. The second lamination layer part is arranged around the opening.

First claim

What is claimed is:

1. A motorcycle in which a carbon fiber is used for an air cleaner unit, and outside air is introduced through the air cleaner unit into an engine, comprising:
a lamination layer part formed by laminating plural kinds of materials is arranged in a region of at least a portion of the air cleaner unit, and the lamination layer part is formed of a carbon fiber layer and an elastic material layer;
an air intake duct for introducing the outside air; and
a casing body provided with an opening to be connected to the air intake duct, wherein
each of the carbon fiber layer and the elastic material layer is provided in multiple layers in the lamination layer part, and the lamination layer part comprises a first lamination layer part and a second lamination layer part of which the elastic material layer is thicker than that of the first lamination layer part,
the second lamination layer part is arranged around the opening,
the upper surface of the casing body is formed with a recess portion for accommodating a battery,
the recess portion is formed in the first lamination layer part,
a cushioning material is arranged between the first lamination layer part and the battery, and
the battery is mounted on the upper surface of the casing body by fastening a battery cover for covering the battery.

2. The motorcycle according to claim 1 , wherein the engine is formed in a V-type, and includes cylinder sections of the engine each of which is arranged in front of and at the rear of the casing body, and a pair of left and right vehicle body frames is located on left and right lateral sides of the casing body, and wherein the first lamination layer part is arranged on surfaces of the casing body facing the cylinder sections, and the second lamination layer part is arranged in at least a part of an upper surface of the casing body.
