Abstract

An air cleaner apparatus (102) has an air cleaner case (105), a main filter element (170) dividing an interior of the air cleaner case (105) into a first chamber (115) and a second chamber (145), an intake passage (130) for sucking air outside the air cleaner case (105) into the first chamber (115), a discharge passage (148) for discharging the air within the second chamber (145) out of the air cleaner case (105), and a pre-filter element (138) including a wet-type element disposed in the first chamber (115). The intake passage (130) has an air outlet port (132) for blowing off air into the first chamber (115). The pre-filter element (138) is disposed spaced apart from the air outlet port (132) so as to be positioned on the axis line of the air outlet port (132).

Description

technical field [0001] The present invention relates to an air cleaner device mounted on a saddle type vehicle and a saddle type vehicle having the air cleaner. [0002] In addition, this application claims the priority of Japanese Patent Application No. 2011-289098 for which it applied on December 28, 2011, The whole content of this application is incorporated in this specification as a reference. Background technique [0003] In a saddle type vehicle having an engine as a driving source, if dust or the like is mixed in the air supplied to the engine, the inside of the engine may be worn, and as a result, the life of the engine may be shortened. Therefore, an air cleaner, which is a device for cleaning air, is usually provided upstream of an intake pipe that supplies air to the engine. [0004] In addition, when the amount of dust contained in the air is large, components (filters) in the air cleaner case quickly cause clogging. As a method of suppressing clogging, it is ...
