An air cleaner device for exchanging an element without permitting dust
and dirt collected between the element and an air guide member in a clean
side to fall and for smoothly permitting intake air to be supplied to the
engine. An air cleaner device includes a cylindrical element with an air
guide member including a guide sleeve formed into a diameter smaller than
an inner diameter between element inner walls of the element which are
served for inserting the air guide member from one end of the element and
flange portions which are formed on the guide sleeve to be brought into
contact with one end surface of the element. A cleaner case houses the
element and the air guide member and an air intake duct portion which is
mounted on a lower portion of the cleaner case and is arranged below the
air guide member.
