Problems solved by technology

[0004] However, if the anechoic chamber is installed as in the above-mentioned prior art, in addition to the man-hours for attaching and fixing the filter cover member to the base member, the man-hours for attaching and fixing the anechoic cover member to the base member are also required.
Therefore, in the case of installing a plurality of anechoic chambers, it is necessary to attach and fix the anechoic cover member to the base member according to the number of anechoic chambers, which increases man-hours.

Embodiment Construction

[0037] The best mode for carrying out the present invention will be described below with reference to the drawings. It should be noted that, in the following description, the front and rear, left and right, and up and down of the vehicle are based on the usage state of the vehicle, specifically, the traveling direction of the vehicle. In addition, the inner direction and the outer direction refer to the direction toward the center of the vehicle body as the inner direction, and the opposite side as the outer direction. The left-right direction has the same meaning as the vehicle width direction. Furthermore, with regard to the vehicle-mounted components, the above-mentioned standards are applied in principle in the state of being mounted on the vehicle. However, it is also sometimes based on the graphical state of a specific diagram. In addition, direct arrows sometimes indicate directions in the drawings.

Abstract

The present invention provides an air filter, when the air filter is provided with anechoic chambers, if members for fixing anechoic covers are provided according to the number of the anechoic chambers, the manhour will be increased, thereby the anechoic chambers are configured simply without addition of special manhour. The air filter is configured that a sealing space formed by a first casing (123) and an auxiliary air filter cover (133) is divided into a clean side (144) arranged on the side of a getter device and a dirty side arranged on the opposite side. The dirty side is divided into afirst anechoic chambers (141), a second anechoic chamber (142) and a third anechoic chamber (143) by a separator assembling body (140), the first anechoic chamber (141) is open to atmosphere through a first communicating pipe (126), the second anechoic chamber (142) is communicated with the first anechoic chamber (141) through a second communicating pipe (147) arranged on a first separator (145),and is communicated with the third anechoic chamber (143) through a third communicating pipe (148) arranged on a second separator (146). The separator assembling body (140) is clamped between the first casing (123) and the auxiliary air filter cover (133) to form the first anechoic chambers (141), the second anechoic chamber (142) and the third anechoic chamber (143).

Description

technical field [0001] The present invention relates to an air filter installed in vehicles such as motorcycles, and more particularly to an air filter provided with an anechoic chamber in an advantageous structure. Background technique [0002] It is known to install an air filter upstream of an air intake device such as an engine and in the middle of an air intake path. In this prior art, an anechoic chamber and an air filter are integrally provided for alleviating suction noise in the air filter, and when the anechoic chamber is installed, an anechoic cover part is provided separately from the filter cover part, and it is installed and fixed. for the base part of the air filter. [0003] [Patent Document 1] Japanese Patent Laid-Open No. 2006-291810. [0004] However, if the anechoic chamber is installed as in the above-mentioned conventional technique, in addition to man-hours for attaching and fixing the filter cover member to the base member, man-hours for attaching a...
