  However, in recent years, it has been demanded that the entire vehicle be made smaller and more compact, and the accommodation space in the engine room has become narrower, and the arrangement space for the air cleaner is limited. Even if the hole is provided, it may be difficult to attach or detach the filter element. Therefore, it is necessary not to impair the workability of attaching and detaching the filter element regardless of the arrangement position in the engine room.

  Moreover, in order to fully demonstrate the performance and function of an air cleaner, the accommodation attitude | position at the time of normal use of an air cleaner may be restrict | limited. For example, when it is used in a work vehicle, etc., if a vacuator valve is installed on the air cleaner to take out dust and moisture from the air cleaner in consideration of a dusty environment or work in rainy weather, tilt the air cleaner diagonally. If it is provided to be inclined, there is a problem that dust or the like cannot be discharged sufficiently. Therefore, in consideration of the performance and function of such an air cleaner, the accommodation posture during normal use of the air cleaner is determined, but depending on the accommodation posture, maintenance workability may be impaired.

  In view of the above problems, in the present invention, even when the accommodation space in the engine room becomes narrow, etc., the workability of attaching and detaching the filter element of the air cleaner is not deteriorated, and the air cleaner in the engine room is not reduced. An object of the present invention is to provide an air cleaner device that can be accommodated efficiently without degrading performance.

  In order to solve the above problems, an air cleaner apparatus according to the present invention includes a casing having a filter element arrangement space, a filter element detachably arranged in the filter element arrangement space, and a filter element arrangement space. An air cleaner device comprising a lid that covers and is attached to a casing, and that is disposed in the engine room and purifies the intake air of the engine, wherein the support member is fixed in the engine room, and one end is a support member A swinging member pivotally connected to the other end of the swinging part and pivotably mounted about the pivoting part, and a swinging member for biasing the swinging member so that the other end swings away from the support member.
