The upper surface of the lower pressure contact portion 69a is substantially flat. The separation dimension between the upper end surface of the lower pressure contact portion 69a and the lower surface of the upper rail 68 is set to be approximately the same as the vertical dimension of the frame member 42, and the lower pressure contact portion 69a is reliably in pressure contact with the frame member 42. It is like that.

  As shown in FIG. 8, an upper pressure contact portion (first pressure contact portion) 68 a that presses against the frame member 42 of the filter 40 is provided at the front portion of the left upper rail 68. The upper pressure contact portion 68 a is configured by a protruding portion that protrudes downward from the upper surface of the upper rail 68. The upper pressure contact portion 68a is disposed so as to be in pressure contact with the frame member 42 of the air filter 40 in a completely inserted state from the upper side in the vicinity of the front left corner. That is, the upper pressure contact portion 68a and the lower pressure contact portion 69a are located in the vicinity of both ends in the width direction of the frame member 42.

  The lower surface of the upper pressure contact portion 68a is formed substantially flat. The separation dimension between the lower end surface of the upper pressure contact portion 68a and the lower surface of the lower rail 69 is set to be approximately the same as the vertical dimension of the frame member 42, so that the upper pressure contact portion 68a is securely in pressure contact with the frame member 42. It has become.

  On the inner surface of the front wall portion of the casing 50, an upper support portion 73 that supports the upper surface of the air filter 40 and a lower support portion 74 that supports the lower surface are formed so as to protrude into the casing 50. The upper support portion 73 is integrated with the upper rail 68, and the lower support portion 74 is integrated with the lower rail 69.

  On the other hand, as shown in FIG. 6 and the like, the air filter 40 is integrally provided with a lid 41 for closing the filter insertion hole 63 of the casing 50. First, the structure of the air filter 40 will be described. The air filter 40 includes a frame member 42 and a filter material 43. The frame member 42 has a substantially rectangular shape in plan view, and forms the outer shape of the air filter 40. As a material of the frame member 42, for example, an elastic resin material or the like can be used. Thereby, the frame member 42 becomes elastically deformable. The vertical dimension of the frame member 42 is set slightly shorter than the distance between the upper rail 68 and the lower rail 69 of the casing 50, and the frame member 42 smoothly moves between the upper rail 68 and the lower rail 69. To move to.

  Protrusions 42 a and 42 a are respectively formed on the left and right side surfaces of the frame member 42. Further, inside the frame member 42, a central plate portion 42b extending in the front-rear direction is provided at the central portion in the left-right direction. The front end portion of the central plate portion 42 b is integrally formed with the front portion of the frame member 42, and the rear end portion is integrally formed with the rear portion of the frame member 42.

  A known nonwoven fabric or the like can be used for the filter material 43, and the filter material 43 is bent into a pleat shape and integrated with the frame member 42.

  The lid 41 is made of a resin material that is integrally formed with the front portion of the frame member 42. The lid 41 extends from the left and right edges of the frame member 42 to the left and right sides, and extends from the upper and lower edges of the frame member 42 to the upper and lower sides. The size of the lid 41 is larger than the filter insertion hole 63 of the casing 50. Specifically, the lid 41 in the closed state covers the entire seal surface 63a, which is the peripheral edge of the filter insertion hole 63. It is the size that can be.

  On the outer peripheral side of the lid 41, an inclined surface portion 41 a that is inclined with respect to the insertion direction of the air filter 40 is provided at a portion facing the peripheral edge portion of the filter insertion hole 63 of the casing 50. The inclined surface portion 41 a is continuous over the entire circumference of the lid 41. The inclination direction of the inclined surface portion 41a is a direction positioned closer to the distal end side in the filter insertion direction as it approaches the inner peripheral edge portion of the inclined surface portion 41a. The inclined surface portion 41a is inclined in the same direction as the seal surface 63a of the casing 50. In this embodiment, when the lid 41 is in the closed state, the inclined surface portion 41a and the seal surface 63a are inclined at an approximately parallel angle. Is set. The inclination angle of the inclined surface portion 41a with respect to the arrow X is preferably 45 °, but is not limited to this, and is preferably set in the range of 30 ° to 60 °, for example.

  A sealing material 70 for sealing between the peripheral edge of the lid 41 and the peripheral edge of the filter insertion hole 63 of the casing 50 is attached to the inclined surface portion 41a. The sealing material 70 can be composed of, for example, foamed urethane or the like, but can be composed of various rubber materials, elastomers, or the like in addition to urethane foam.

  The cross section of the sealing material 70 is a rectangular cross section. For example, the sealing material 70 formed in a long shape can be attached to the inclined surface portion 41a with an adhesive member such as a double-sided tape. At this time, since the sealing material 70 has a rectangular cross section, one surface of the four outer surfaces of the sealing material 70 is attached to the inclined surface portion 41a. Since the inclined surface portion 41a is inclined as described above, the corner portion of the sealing material 70 attached to the inclined surface portion 41a protrudes as shown in FIGS. 6 (a) and 6 (b).

  The lid 41 is provided with engagement protrusions 41d and 41d that engage with the engagement claws 63b and 63b of the casing 50, respectively. One engagement protrusion 41d is formed so as to protrude upward from the center in the left-right direction of the upper edge of the lid 41. The other engagement protrusion 41d is formed so as to protrude downward from the central portion in the left-right direction of the lower edge portion of the lid 41. These engaging protrusions 41d and 41d are elastically deformed.

  When the sealing material 70 is attached to the inclined surface portion 41a of the lid 41, since the inclined surface portion 41a faces the outer peripheral side of the lid 41, the long sealing material 70 is applied while being placed on the inclined surface portion 41a. I'll do it. Thereby, the sticking workability | operativity of the sealing material 70 becomes favorable.

  When the air filter 40 is inserted into the casing 50, the front end side of the air filter 40 in the insertion direction (the front side of the air filter 40) is inserted into the filter insertion hole 63. At this time, the seal surface 63a is inclined so as to be positioned in the casing 50 as it approaches the inner edge of the filter insertion hole 63. Therefore, even if the front end side of the air filter 40 is slightly displaced in the vertical direction or the horizontal direction, the seal It is guided toward the center of the filter insertion hole 63 by the surface 63a. Thereby, insertion workability improves.

  Thereafter, when the front end portion of the air filter 40 is completely inserted into the filter insertion hole 63, the upper and lower sides of the frame member 42 of the air filter 40 are guided toward the front side by the upper rail 68 and the lower rail 69.

  When the air filter 40 is completely inserted, the front portion of the air filter 40 is supported from both the upper and lower sides by the upper support portion 73 and the lower support portion 74, and the left and right sides of the air filter 40 are connected to the upper rail 68 and the lower side. It is supported from both upper and lower sides by the rail 69. At this time, the upper pressure contact portion 68a and the lower pressure contact portion 69a are in pressure contact with each other in the vicinity of both ends in the width direction of the front portion of the frame member 42 of the air filter 40. Due to the pressure contact force of these pressure contact portions 68a and 69a, an upward force is applied to the right side of the frame member 42 and a downward force is applied to the left side of the frame member 42, whereby the frame member 42 is elastically deformed. The upper rail 68 and the lower rail 69 are pressed against each other. Therefore, the frame member 42 can be kept in pressure contact with the upper rail 68 and the lower rail 69 even when an excitation force is applied to the air filter 40 during air blowing or traveling of the vehicle, and the generation of abnormal noise is suppressed. The

  Further, the filter insertion hole 63 is closed by the lid 41 of the air filter 40, and at this time, the lid 41 is pushed in the insertion direction of the air filter 40 and the sealing material 70 is pushed against the sealing surface 63 a at the peripheral edge of the filter insertion hole 63. Then, the engagement protrusions 41d and 41d of the lid 41 are elastically deformed to get over the engagement claw parts 63b and 63b of the casing 50, and the upper engagement protrusion 41d is engaged with the lower engagement claw part 63b. The protrusions 41d engage with the lower engaging claws 63b, respectively. In the state in which the engagement protrusions 41d and 41d are engaged, the lid 41 is pushed rearward (in the opening direction of the filter insertion hole 63) by the reaction force of the sealing material 70, so the engagement protrusions 41d and 41d are engaged. The state engaged with the claw portions 63b and 63b can be reliably maintained.

  As described above, a compressive force is applied to the sealing material 70 by being pushed from the sealing surface 63a of the casing 50. However, the inclined surface portion 41a to which the sealing material 70 is attached faces the sealing surface 63a. Therefore, the sealing material 70 is supported by the inclined surface portion 41a. Therefore, the sealing material 70 can be brought into an appropriate compressed state, and the sealing performance is improved.

  As described above, according to this embodiment, the air filter 40 can be supported from both sides in the air flow direction by the upper rail 68 and the lower rail 69 inside the casing 50. In this state, the upper pressure contact portion 68a and the lower pressure contact portion 69a are pressed against the frame member 42 of the air filter 40 from both sides of the air flow direction, and the frame member 42 can be elastically deformed. Thereby, since the vibration of the frame member 42 is suppressed, generation | occurrence | production of abnormal noise can be suppressed.

  Further, since the upper rail 68 and the lower rail 69 are formed so as to extend in the insertion direction of the air filter 40, the air filter 40 can be easily inserted into a predetermined position inside the casing 50, and the upper pressure contact portion 68a and the lower side The frame member 42 can be reliably elastically deformed by the press contact portion 69a.

  In addition, since the upper pressure contact portion 68a and the lower pressure contact portion 69a are constituted by the protruding portions, the upper pressure contact portion 68a and the lower pressure contact portion 69a are surely brought into pressure contact with the frame member 42 of the air filter 40 with a simple configuration. Can do.

  Further, since the upper pressure contact portion 68a and the lower pressure contact portion 69a are pressed from both sides in the air flow direction in the vicinity of both ends in the width direction of the frame member 42, the frame member 42 can be reliably elastically deformed.

  In the above embodiment, the upper pressure contact portion 68a and the lower pressure contact portion 69a are provided so as to be positioned on both sides in the width direction of the air filter 40. However, the present invention is not limited to this, for example, the upper pressure contact portion 68a and the lower pressure contact portion. The parts 69a may be integrated on one side in the width direction, and one may be provided on the front side of the casing 50 and the other may be provided on the rear side of the casing 50.

  Further, the upper pressure contact portion 68a and the lower pressure contact portion 69a may be combined on the rear side of the casing 50, and one may be provided on the right side and the other on the left side.

  The above-described embodiment is merely an example in all respects and should not be interpreted in a limited manner. Further, all modifications and changes belonging to the equivalent scope of the claims are within the scope of the present invention.
