Air filter

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...

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.
