The flap can be connected to the main body portion so as to be pivotable while suppressing sticking. Moreover, the diameter expansion part is formed so that the sum of the circumferential length of an outer peripheral surface is larger than the circumferential length of the main body side mounting hole. Therefore, it cannot enter the main body side mounting hole by the enlarged diameter portion. That is, the diameter-enlarged portion cannot pass through the main body side mounting hole, and the movement of the connecting member is restricted. As a result, the connecting member is restricted from being displaced in the direction of coming out of the main body side mounting hole, and can be prevented from falling off. Further, the enlarged diameter portion can be formed integrally with the insertion main body portion and the flap connecting portion as a connecting member, resulting in a complicated shape of the flap, an increase in the number of parts, and an accompanying deterioration in assemblability. Can be prevented. Therefore, an increase in manufacturing cost can be suppressed.

  Moreover, in the air conditioning apparatus according to the second aspect of the present invention, in the first or second aspect, the diameter-expanding portion may have a flange portion projecting outward from the other end portion. .

  According to this configuration, a portion that is larger than the circumferential length of the inner peripheral surface of the body-side mounting hole by having a flange portion that protrudes further to the outer peripheral side than the enlarged-diameter portion has a simpler structure. Can be formed.

  Moreover, in the air conditioning apparatus according to the third aspect of the present invention, in any one of the first to third aspects, the enlarged-diameter portion is spaced from the other side of the insertion main body portion at a circumferential interval. You may have the some elastic deformation piece extended toward the edge part side.

  According to this configuration, the enlarged diameter portion is formed by the plurality of elastically deformable pieces extending from the insertion main body portion toward the other end side, thereby making it easier to cause elastic deformation in the enlarged diameter portion. it can. Therefore, an elastic force can be effectively generated in the enlarged diameter portion.

And an engaging claw portion (flap connecting portion) 26 provided on the front side.

  As shown in FIGS. 4, 5, and 7, the connecting shaft 21 has the engagement claw portion 26 in a state where the one end 25 a side of the shaft body 25 is inserted into the shaft insertion hole 24 formed in the housing side bracket 20. It is engaged with the shaft engaging hole 23 of the flap side bracket 19.

  The shaft body 25 of the present embodiment has a cylindrical shape centered on the central axis, that is, the axis O. The shaft main body 25 includes an insertion main body portion 27 having an outer diameter smaller than the inner diameter of the shaft insertion hole 24 and an enlarged diameter portion 30 having an outer diameter larger than the inner diameter of the shaft insertion hole 24.

  The insertion main body 27 is formed such that the sum of the circumferential lengths of the outer circumferential surface is smaller than the circumferential length of the inner circumferential surface of the shaft insertion hole 24. As shown in FIGS. 6 and 7, the insertion main body 27 has a disk shape in which a main surface perpendicular to the central axis (axis O) of the shaft main body 25 is formed on the one end 25 a side of the shaft main body 25. Yes. That is, the insertion main body 27 closes one end 25a of the enlarged diameter portion 30 described later. As shown in FIG. 7, the insertion main body 27 has an outer diameter D on the one end 25 a side that is larger than an opening L 1 of the rectangular shaft engaging hole 23 formed in the flap-side bracket 19. Yes. The insertion main body 27 has an outer diameter D that is smaller than an opening L2 that is the inner diameter of the shaft insertion hole 24.

  The enlarged diameter portion 30 is elastically deformable toward the inner side with the central axis (axis O) with the insertion main body portion 27 as a base portion. At least a part of the enlarged diameter portion 30 is such that the sum of the lengths in the circumferential direction of the outer peripheral surface on the other end 25 b side of the insertion body portion 27 with respect to the shaft insertion hole 24 is in the circumferential direction of the inner peripheral surface of the shaft insertion hole 24. It is formed to be larger than the length. The enlarged diameter portion 30 has a cylindrical shape that increases in diameter as it goes from the one end 25a side to the other end 25b side. As shown in FIGS. 6 and 8, the enlarged diameter portion 30 has slits 28 formed at a plurality of locations in the circumferential direction (four locations in the present embodiment). The slit 28 extends from the other end 25b of the shaft body 25 toward the one end 25a side in the direction of the central axis (axis O) of the shaft body 25 to the insertion body 27. The slit 28 forms a plurality of elastic deformation pieces 29 in the enlarged diameter portion 30 at intervals in the circumferential direction.

  The elastic deformation piece 29 extends from the insertion main body 27 toward the other end 25b. That is, the elastically deformable piece 29 of the present embodiment has a cantilever shape with the insertion main body 27 as a fixed end and the distal end on the other end 25b side as a free end. Thereby, the elastic deformation piece 29 can be elastically deformed so that the tip portion approaches the central axis (axis line O).

  Here, in each elastic deformation piece 29, the outer peripheral surface 29 f facing the outer side in the radial direction of the shaft body 25 is viewed from the direction of the axis O along the center axis (axis O) of the shaft body 25. ). That is, the elastic deformation piece 29 of the present embodiment is a plate-like member that is curved around the central axis (axis O).

  As shown in FIG. 7, the outer peripheral surface 29 f of each elastic deformation piece 29 has a first tapered surface 31, a second tapered surface 33, and an orthogonal surface 32.

  The first taper surface is formed such that a radial separation dimension r from the central axis (axis O) gradually increases from the insertion main body 27 toward the other end 25b of the shaft main body 25.

  The orthogonal surface 32 is continuously formed at the other end portion of the first tapered surface 31. The orthogonal surface 32 is formed to protrude outward in the radial direction perpendicular to the central axis of the shaft body 25 with respect to the first tapered surface 31.

  The second tapered surface 33 is formed continuously at the radially outer end of the orthogonal surface 32. The second taper surface 33 is formed such that the radial separation dimension r from the central axis (axis O) gradually increases from the first taper surface 31 toward the other end 25 b of the shaft body 25 from the orthogonal surface 32. Has been.

  Since the outer peripheral surface 29f of each elastic deformation piece 29 has the first tapered surface 31, the orthogonal surface 32, and the second tapered surface 33 as described above, the enlarged diameter portion 30 includes the first tapered portion 41, A second taper portion 43 is formed.

  The first tapered portion 41 is a region where the first tapered surface 31 is formed in the enlarged diameter portion 30. The first taper portion 41 extends from the insertion body portion 27 toward the other end 25b. The first taper portion 41 is inserted into the shaft insertion hole 24 together with the insertion main body portion 27.

  The second tapered portion 43 is a region where the orthogonal surface 32 and the second tapered surface 33 are formed in the enlarged diameter portion 30. The second taper portion 43 projects radially outward from the end of the first taper portion 41 on the other end 25 b side. The second taper portion 43 has an outer diameter that gradually increases from the orthogonal surface 32 toward the other end 25b. The second taper portion 43 is disposed on the opposite side of the flap side bracket 19 with respect to the housing side bracket 20 in a state where the shaft body 25 is inserted into the shaft insertion hole 24.

  Further, the enlarged diameter portion 30 is formed with a flange portion 44 protruding outward in the radial direction at the other end 25 b of the shaft body 25. The flange portion 44 protrudes radially outward from the second tapered surface 33 at the other end 25 b of the shaft body 25. The flange portion 44 has the largest outer diameter in the shaft body 25.

  Here, as shown in FIG. 8, the circumferential length of the outer peripheral surface of each elastic deformation piece 29 is Lr. In the present embodiment, the sum (Lr × 4) of the circumferential length Lr of the outer peripheral surface of the flange portion 44 closest to the other end 25 b of the enlarged diameter portion 30 is the circumference of the inner peripheral surface of the shaft insertion hole 24. The circumferential length Lr of each elastic deformation piece 29 is set so as to be larger than the length in the direction. That is, the enlarged diameter portion 30 is formed such that the sum of the circumferential lengths is larger than the shaft insertion hole 24 at least at the flange portion 44.

  As shown in FIGS. 6 and 7, the engaging claw portion 26 has a pair of beam portions 26 a that protrude in the direction of the axis O from the end surface on the one end 25 a side of the insertion main body portion 27, and a hook that protrudes from the tip of the beam portion 26 a. Part 26b.

  The beam portion 26 a extends in parallel to each other along the axis O direction in which the central axis (axis O) of the shaft main body 25 extends from the insertion main body 27 of the one end 25 a of the shaft main body 25. Each of the pair of beam portions 26a has a rectangular cross section. The pair of beam portions 26a are formed such that outer surfaces 26s, which are surfaces opposite to the surfaces on which the beam portions 26a face each other, are parallel to each other.

  The flange portion 26b is formed integrally with the beam portion 26a at the tip of the beam portion 26a. The collar part 26b protrudes toward the outer side opposite to the direction in which the beam parts 26a face each other. As shown in FIG. 7, the engagement claw portion 26 has an opening dimension in the longitudinal direction of the rectangular shaft engagement hole 23 formed in the flap side bracket 19 such that the interval between the outer surfaces 26 s of the pair of beam portions 26 a is. It is formed slightly smaller than L1.

  Here, at least the engaging claw portion 26 of the connecting shaft 21 is formed of a flexible material (elastically deformable material). As the flexible material, for example, engineering plastics such as polyacetal resin (POM) can be employed. As a result, the pair of beam portions 26a constituting the engaging claw portion 26 has a central axis (axis O) of the shaft main body 25 such that the distal end side where the flange portion 26b is formed approaches the insertion main body portion 27. It can be elastically deformed in the direction approaching.

  The engagement claw portion 26 is engaged with a rectangular shaft engagement hole 23 formed in the flap side bracket 19. For this purpose, the pair of beam portions 26a of the engagement claw portion 26 are inserted into the shaft engagement hole 23 in a state where the pair of beam portions 26a are elastically deformed in a direction in which the flange portions 26b of the distal end portions approach each other. When the flange portion 26 b passes through the shaft engagement hole 23, the elastically deformed beam portion 26 a is restored, and the flange portion 26 b engages with the shaft engagement hole 23. In this state, one end 25a of the insertion main body portion 27 of the connecting shaft 21 abuts against a surface of the flap side bracket 19 facing the other end 25b side. In this way, the connecting shaft 21 is fixed to the flap-side bracket 19 so that it cannot rotate and cannot move in the direction of the axis O.

  In the air conditioning apparatus 1 of the present embodiment, the flap 8 is attached to the housing 2 via the connecting shaft 21 by the shaft body 25 being inserted into the shaft insertion hole 24 of the housing-side bracket 20. The outer diameter of the shaft body 25 is formed slightly smaller than the inner diameter of the shaft insertion hole 24. Thereby, the shaft main body 25 is rotatably supported around the axis O in the shaft insertion hole 24 of the housing side bracket 20.

  According to the above embodiment, in the shaft body 25, the enlarged diameter portion 30 can be elastically deformed radially inward. Therefore, in a state where the first taper portion 41 of the shaft body 25 is inserted into the shaft insertion hole 24, the elastic deformation piece 29 comes into sliding contact with being pressed against the inner peripheral surface of the shaft insertion hole 24. Thereby, the 1st taper part 41 fits in with respect to the shaft insertion hole 24 without gap, and the flap 8 can be rotated with respect to the air conditioner 3 while suppressing the backlash between the shaft insertion hole 24 and the connecting shaft 21. Can be linked to.

  Further, as shown in FIG. 9, in the air conditioner 1, the connection shaft 21 is pushed into the shaft insertion hole 24 in the axis O direction by an excessive force due to factors such as the flap 8 moving in the axis O direction. There is. At this time, there is a possibility that the portion up to the second taper portion 43 of the shaft main body 25 is inserted into the shaft insertion hole 24 over the orthogonal surface 32.

  However, since the sum of the circumferential lengths of the outer peripheral surface of the enlarged diameter portion 30 that is elastically deformable is formed to be larger than the circumferential length of the inner peripheral surface of the shaft insertion hole 24, the connecting shaft 21. The displacement in the direction of the axis O can be regulated.

  Specifically, in the state where the second taper portion 43 is inserted through the shaft insertion hole 24, the second taper surface 33 is centered by the inner peripheral surface of the shaft insertion hole 24 as shown in FIGS. 9 and 10. The elastic deformation piece 29 is elastically deformed by being pressed radially inward. As a result of each of the plurality of elastic deformation pieces 29 being pressed radially inward by the shaft insertion hole 24, the plurality of elastic deformation pieces 29 abut against each other in the circumferential direction. In this state, in the shaft body 25, the sum of the circumferential lengths Lr of the elastic deformation pieces 29 at the flange portion 44 is larger than the circumferential length of the shaft insertion hole 24. Therefore, the diameter-expanded portion 30 of the connecting shaft 21 cannot enter the shaft insertion hole 24 any more in a state where the plurality of elastic deformation pieces 29 are in contact with each other in the circumferential direction. That is, the flange portion 44 cannot pass through the shaft insertion hole 24 and comes into contact with the housing side bracket 20, and movement of the connecting shaft 21 in the central axis (axis O) direction is restricted. As a result, the connecting shaft 21 is restricted from being displaced in the direction of coming out of the shaft insertion hole 24 and can be prevented from falling off.

Further, the enlarged diameter portion 30 having such an elastic deformation piece 29 can be integrally formed with the shaft body 25 and the engaging claw portion 26 as the connecting shaft 21. Therefore, it is possible to prevent the shape of the flap 8 from becoming complicated, increasing the number of parts, and causing deterioration in assemblability associated therewith. Therefore, an increase in manufacturing cost can be suppressed.
Thus, according to the air conditioner 1 as described above, it is possible to suppress an increase in cost and prevent the flap 8 from being inadvertently dropped.

  Further, the second tapered portion 43 of the enlarged diameter portion 30 can reliably suppress displacement in the direction in which the connecting shaft 21 is removed from the shaft insertion hole 24. Further, since the circumferential length of the outer peripheral surface gradually increases from the insertion main body portion 27 toward the first tapered portion 41 and the second tapered portion 43 and the other end 25b, the inner peripheral surface of the shaft insertion hole 24 A portion larger than the circumferential length can be formed with a simple structure.

  Further, the flange portion 44 that protrudes further to the outer peripheral side than the second taper portion 43 in the enlarged diameter portion 30 allows a portion that is larger than the circumferential length of the inner peripheral surface of the shaft insertion hole 24 to be simpler. It can be formed with a simple structure.

  Further, the orthogonal surface 32 formed in the second tapered portion 43 abuts on the periphery of the shaft insertion hole 24, so that the displacement in the direction in which the connecting shaft 21 comes out of the shaft insertion hole 24 can be reliably suppressed. This also prevents inadvertent dropping of the flap 8.

  Further, by providing the elastic deformation piece 29, it is possible to easily cause elastic deformation in the enlarged diameter portion 30. Therefore, an elastic force can be effectively generated in the enlarged diameter portion 30. Thereby, it can suppress stably that the enlarged diameter part 30 is pressed by the internal peripheral surface of the shaft insertion hole 24 with an excessive force, and the friction between the shaft insertion hole 24 and the shaft main body 25 increases. . Further, it is possible to effectively suppress the backlash between the shaft insertion hole 24 and the connecting shaft 21 and the vibration of the connecting shaft 21.

  Although the embodiment of the present invention has been described in detail above, some design changes can be made without departing from the technical idea of the present invention.

  For example, although the enlarged diameter part 30 was set as the structure provided with the 1st taper part 41, the 2nd taper part 43, and the flange part 44, it is not limited to such a structure. For example, if the sum of the circumferential length Lr of the outer peripheral surface is larger than the circumferential length of the inner circumferential surface of the shaft insertion hole 24, the enlarged diameter portion 30 has the first tapered portion 41 and the second tapered portion 41. What is necessary is just to have at least one of the taper part 43 and the flange part 44. FIG.
