Problems solved by technology

[0006] exist Figure 8 Among them, since the mixed gas regulating valve 100 is installed on the air filter side volume type housing 104 with a plurality of bolts and other fixing parts 103, 103, the assembly of the mixed gas regulating valve 100 will take a lot of time; at the same time, Since the secondary air passage 105 and the negative pressure passage 106 protrude from the side, it is difficult to use tools when screwing in the fixing piece 103, which brings difficulties to assembly

Abstract

An insert hole 36a for directly inserting the secondary air suction port 35 of the secondary air control valve 25 is provided in the air cleaner 14, and the case 37 of the secondary air control valve 25 is supported by an air delivery tube 36 having the insert hole 36a opened therein. That easily support a secondary air control valve, easily install the secondary air control valve in an air cleaner, reduce the number of the parts for connecting the secondary air control valve to the air cleaner, and reduce a cost for installing the secondary air control valve.

Description

technical field [0001] The present invention relates to a structure suitable for an air cleaner for a vehicle in which a secondary air control valve can be easily assembled and an increase in assembly cost can be suppressed. Background technique [0002] Provide an air passage from the air filter side to the intake passage side or exhaust passage side of the engine, and set a secondary air control valve in the middle of the air passage as the air filter side connecting the secondary air control valve The structure, for example, is known in Japanese Patent Application Laid-Open No. 60-87325 "Secondary Air Control Device for Internal Combustion Engine". [0003] Figure 2 of the above-mentioned publication is taken as the following Figure 8 , the above-mentioned bulletin Figure 4 as the following Figure 9 Be explained. Symbols changed. [0004] Figure 8 It is a cross-sectional view of the existing secondary air control valve. As the mixed gas regulating valve 100 of the...
