Patent number: 6039777Abstract: An air filter device and an automobile having the same includes an air filter bent without disassembling a cowl to be simply and easily replaced within a narrow space, and the air filter is commonly utilized to both left-handed drive type and right-handed drive type automobiles. For this, an air filter member is formed with a creasing part throughout the overall portion thereof. A pair of frame members support the marginal edge of the air filter member, and a connecting frame member is integrally connected to the ends of the first frame member and second frame member to allow for bidirectional bending of the air filter member. Thus, the air filter is simply replaced without causing an interference with a frame mounted with a shock absorber. Also, the second frame member is upwardly bent at any time even though the up and down portions are reversed to have compatibility capable of being commonly employed into the left-handed drive type automobile and right-handed drive type automobile.Type: GrantFiled: June 19, 1998Date of Patent: March 21, 2000Assignee: Daewoo Motor Co, Ltd.Inventor: Jeong-Ki Lee
