Air cleaner device

An air cleaner device for filtering air comprising:

• a hollow housing having an inlet portion, an outlet portion, and a flow passage therein which is communicated with said inlet portion and said outlet portion, said housing also having an opening which is disposed between said inlet portion and said outlet portion, and communicates said flow passage with the exterior of said housing;
• a filter element inserted through said opening into said flow passage, disposed between said inlet portion and said outlet portion, so a to filter air flowing through said flow passage, said filter element having a first side surface and a second side surface, and said filter element having an end plate mounted on an outer periphery thereof;
• a lid mounted on said housing for opening and closing said opening;
• a generally annular wall portion which is formed on an inner peripheral surface of said housing and is exposed to said flow of air through said flow passage;
• resilient means coupled to said housing for resiliently biasing said first side surface of said filter element to resiliently bias said end plate toward said wall portion;
• a gasket provided between said wall portion and said end plate to form a seal therebetween;
• and
• guide members coupled to said wall portion of said housing having respective contact portions which receive said end plate when said filter element is inserted through said opening into said flow passage, said contact portions being so arranged that a seal surface of said end plate for contact with said gasket is biased away from said wall portion and when said end plate is received into said contact portions, and said end plate is released from said contact portions upon further insertion of said filter element into said flow passage, so that said end plate is resiliently biased toward said wall portion through said gasket.

• a filter element inserted through said opening into said flow passage, disposed between said inlet portion and said outlet portion, so as to filter air flowing through said flow passage, said filter element being disposed in intersecting relation to said flow passage;
• a lid mounted on said housing for opening and closing said opening;
• resilient members coupled to said housing having one end fixedly mounted on a bottom portion of said flow passage on an inner side of said housing and a free end resiliently biasing said filter element to withstand against movement in said flow passage;
• and
• guide members coupled to said wall portion of said housing for guiding said filter element when said filter element is inserted into said flow passage through said opening, said guide members being provided on said inner side of said housing along said flow passage,
• said guide members comprising a supporting surface being arranged related to said free ends of said resilient members so that said filter element is properly inserted into said flow passage to be biased by said resilient members to withstand against movement in said flow passage.
