Accordingly, it is possible to suppress rattling between the main body side mounting hole and the connecting member caused by the gap between the main body side mounting hole and the mounting hole insertion portion. Therefore, by the elastic deformation of an elastic deformation piece which is brought into slide-contact with the inner circumferential surface of the main body side mounting hole, when turning the flap, it is possible to suppress the vibration of the connecting member relative to the main body side mounting hole.
- In the air conditioner according to a second aspect of the invention, in the first aspect, the elastic deformation portion has a swelling portion which is formed to be thicker than a proximal end portion connected to the mounting hole insertion portion and is formed at a distal end portion to swell radially outward from the outer circumferential surface of the mounting hole insertion portion.
- In this way, by forming the swelling portion formed at the distal end portion to be thinner than the proximal end portion, the elastic deformation portion can be easily elastically deformed. Accordingly, it is possible to effectively perform suppression of rattling between the main body side mounting hole and the connecting member, and suppression of the vibration of the connecting member, using the elastic deformation portion.

FIGS. 4 and 5 , the mountingportion 17 includes aflap side bracket 19, ahousing side bracket 20, and a connecting shaft (a connecting member) 21. Theflap side bracket 19 is provided integrally with a flap main body 18 of theflap 8. Thehousing side bracket 20 is provided in thehousing 2. The connecting shaft (the connecting member) 21 connects theflap side bracket 19 and thehousing side bracket 20. - The
flap 8 includes the flap main body 18 having a laterally long plate shape, and theflap side bracket 19 provided on the flap main body 18 at a position corresponding to the mountingportion 17. - The
flap side bracket 19 is formed integrally on onesurface 18f of the flap main body 18 to extend in an orthogonal direction from thesurface 18f of the flap main body 18. Theflap side bracket 19 has a plate shape. A main surface orthogonal to the axis O is formed on theflap side bracket 19. - The shape of the
flap side bracket 19 viewed from the direction of the axis O is a triangular shape. Theflap side bracket 19 is formed with a rectangularshaft engaging hole 23 that passes therethrough in the direction of the axis O (seeFIG. 5 ). - The
housing side bracket 20 has a plate shape. On thehousing side bracket 20, a main surface orthogonal to the direction of the axis O is formed so as not to inhibit the flow of air A that is blown out of theair outlet 4. A shaft insertion hole (a main body side mounting hole) 24 passing through in the direction of the axis O is formed in thehousing side bracket 20. Theshaft insertion hole 24, for example, has a circular shape. - As illustrated in
FIGS. 6 and7 , the connectingshaft 21 includes a shaft main body (a mounting hole insertion portion) 25, an engaging claw portion (a flap connecting portion) 26, and an elastic deformation piece (an elastic deformation portion) 30. - As illustrated in
FIGS. 4 to 7 , the engagingclaw portion 26 of the connectingshaft 21 is engaged with theshaft engaging hole 23 of theflap side bracket 19 in a state in which a oneend 25 a side of the shaftmain body 25 is inserted into theshaft insertion hole 24 formed in thehousing side bracket 20. - The shaft
main body 25 of the present embodiment has a bottomed cylindrical shape centered on the central axis (axis O). As illustrated inFIGS. 6 and7 , the shaftmain body 25 has a mainbody tube portion 41, anend surface portion 42 and aflange portion 43. - The main
body tube portion 41 has a cylindrical shape centered on the central axis (axis O). In a part in the circumferential direction of the mainbody tube portion 41, a throughhole 29 passing through a part of the outer circumferential surface in the direction of the central axis (the axis O) is formed. As illustrated inFIG. 7 , an outer diameter dimension D of the oneend 25a side, which is one end portion in the extending direction of the mainbody tube portion 41, is formed larger than an opening dimension of the rectangularshaft engaging hole 23 formed in theflap side bracket 19. The outer diameter dimension D of the mainbody tube portion 41 is formed to be smaller than the opening portion dimension L2 which is the inner diameter of theshaft insertion hole 24. - The
end surface portion 42 is provided at the oneend 25a of the mainbody tube portion 41. Theend surface portion 42 has a disc shape in which a main surface orthogonal to the central axis of the shaftmain body 25 is formed. That is, theend surface portion 42 closes the opening of the oneend 25a of the mainbody tube portion 41. - The
flange portion 43 is provided on the other end 25b side which is the other end portion in the extending direction of the mainbody tube portion 41. Theflange portion 43 protrudes radially outward from the outer circumferential surface of the mainbody tube portion 41 in an annular shape. Theflange portion 43 is integrally formed at the other end 25b of the mainbody tube portion 41. Theflange portion 43 prevents the shaftmain body 25 from being moved to theflap side bracket 19 side and from being extracted from theshaft insertion hole 24. - As illustrated in
FIGS. 6 and7 , the engagingclaw portion 26 has a pair ofbeam portions 26a protruding from the end surface of the oneend 25a side of theend surface portion 42 in the direction of the axis O, andflange portions 26b protruding from the front ends of thebeam portions 26a. - The
beam portions 26a extend to be parallel to each other from theend surface portion 42 of the oneend 25a of the shaftmain body 25 in the extending direction of the central axis (axis O) of the shaftmain body 25. Each of the pair ofbeam portions 26a has a rectangular cross-section.Outer surfaces 26s of the pair ofbeam portions 26a, which are surfaces of an opposite side to the surface of the side on which thebeam portions 26a face each other, are formed parallel to each other. - The
flange portions 26b are formed integrally at the front end portions of thebeam portions 26a. Theflange portions 26b protrude toward the outside of the side opposite to the direction in which thebeam portions 26a face each other. As illustrated inFIG. 7 , in the engagingclaw portion 26, a gap between theouter surfaces 26s of the pair ofbeam portions 26a is formed slightly smaller than the opening dimension Lin the longer direction of the rectangularshaft engaging hole 23 formed in theflap side bracket 19. - Here, at least the engaging
claw portion 26 of the connectingshaft 21 is formed of a flexible material (an elastically deformable material). As the flexible material, for example, it is possible to adopt engineering plastic such as a polyacetal resin (POM). Accordingly, the pair ofbeam portions 26a constituting the engagingclaw portion 26 can be elastically deformed in the direction of approaching the central axis (the axis O) of the shaftmain body 25 so that the front end sides formed with theflange portions 26b approach each other with respect to theend surface portion 42. - The engaging
claw portion 26 is engaged with the rectangularshaft engaging hole 23 formed in theflap side bracket 19. The engagingclaw portion 26 is inserted into the engaginghole 23, while elastically deforming the pair ofbeam portions 26a of the engagingclaw portion 26 in the direction in which theflange portions 26b of the front end portion approach each other. When theflange portions 26b have passed through theshaft engaging hole 23, the elasticallydeformed beam portions 26a are restored, and theflange portions 26b are engaged with theshaft engaging hole 23. In this state, the oneend 25a of the mainbody tube portion 41 of the connectingshaft 21 abuts the surface facing the other end 25b side of theflap side bracket 19. In this way, the connectingshaft 21 is non-rotatably and non-movably fixed to theflap side bracket 19 in the direction of the axis O. - The
elastic deformation piece 30 at least partially swells radially outward from the outercircumferential surface 25f of the shaftmain body 25. Theelastic deformation piece 30 is elastically deformable in the radial direction. Specifically, theelastic deformation piece 30 is provided inside the throughhole 29 to be spaced apart from the mainbody tube portion 41. Thus, theelastic deformation piece 30 of this embodiment forms a pair ofslits 29a which extends in the direction of the central axis (axis O) of the shaftmain body 25 from the other end 25b toward the oneend 25a side with respect to the mainbody tube portion 41. The pair ofslits 29a is formed in the circumferential direction of the mainbody tube portion 41 at intervals to interpose theelastic deformation piece 30 therebetween. Theelastic deformation piece 30 extends in the direction of the central axis (axis O) from the surface facing the oneend 25a side of theflange portion 43. Aproximal end portion 30a of theelastic deformation piece 30 is a fixed end which is integrally connected to theflange portion 43. Adistal end portion 30b of theelastic deformation piece 30 is a free end which is separated from the mainbody tube portion 41 and theend surface portion 42. Thus, theelastic deformation piece 30 is formed in a cantilever shape. Thedistal end portion 30b is elastically deformable in the radial direction of the shaftmain body 25. - The
proximal end portion 30a side of theelastic deformation piece 30 from the vicinity of the center in the direction of the central axis (the axis O) is athin portion 31 which is thinner than the thickness of the mainbody tube portion 41. Thedistal end portion 30b side of theelastic deformation piece 30 from the vicinity of the center in the direction of the central axis (the axis O) is athick portion 32 which is thicker than the thickness of the mainbody tube portion 41. Thethick portion 32 is formed to be thicker than thethin portion 31 of theproximal end portion 30a side connected to theflange portion 43. Thethick portion 32 is a swellingportion 33 that swells radially outward from the outercircumferential surface 25f of the shaftmain body 25. In this way, in a part in the circumferential direction of the shaftmain body 25, the swellingportion 33 of theelastic deformation piece 30 swells radially outward. - In the
air conditioner 1 of the present embodiment, the shaftmain body 25 is inserted into theshaft insertion hole 24 of thehousing side bracket 20. Therefore, theflap 8 is mounted to thehousing 2 via the connectingshaft 21. The outer diameter of the shaftmain body 25 is formed to be slightly smaller than the inner diameter of theshaft insertion hole 24. Thus, the shaftmain body 25 is supported within theshaft insertion hole 24 of thehousing side bracket 20 to be freely rotatable around the axis O. Therefore, it is possible to rotatably connect theflap 8 to theair conditioning device 3 by the connectingshaft 21. - Here, when the shaft
main body 25 is inserted into theshaft insertion hole 24, the swellingportion 33 of theelastic deformation piece 30, which swells radially outward in a part in the circumferential direction of the shaftmain body 25, abuts an innercircumferential surface 24f of theshaft insertion hole 24. That is, theelastic deformation piece 30 enters a state in which thedistal end portion 30b side provided with the swellingportion 33 is pressed radially inward by the innercircumferential surface 24f of theshaft insertion hole 24. Therefore, theelastic deformation piece 30 is elastically deformed, using theproximal end portion 30a provided with thethin portion 31 as a fulcrum. As a result, the swellingportion 33 enters a state of being pushed back toward the innercircumferential surface 24f of theshaft insertion hole 24 by the elastic force. Therefore, a frictional force is generated between the swellingportion 33 and the innercircumferential surface 24f of theshaft insertion hole 24. - According to the embodiment, the shaft
main body 25 is provided with theelastic deformation piece 30 that swells radially outward from the outercircumferential surface 25f of the shaftmain body 25. Therefore, when the shaftmain body 25 is inserted into theshaft insertion hole 24, the swellingportion 33 of theelastic deformation piece 30 comes into slide-contact with the innercircumferential surface 24f of theshaft insertion hole 24, while being pushed back toward the innercircumferential surface 24f of theshaft insertion hole 24. As a result, it is possible to suppress the rattling between theshaft insertion hole 24 and the connectingshaft 21 caused by the gap between theshaft insertion hole 24 and the mainbody tube portion 41. Therefore, by the elastic deformation of theelastic deformation piece 30 brought into slide-contact with the innercircumferential surface 24f of theshaft insertion hole 24, it is possible to suppress the vibration of the connectingshaft 21 relative to theshaft insertion hole 24 when turning theflap 8. Thus, it is possible to suppress an occurrence of abnormal noise generated at the time of operation of the flap. - Such an
elastic deformation piece 30 can be formed integrally with theflange portion 43 of the connectingshaft 21. Therefore, there is no need to provide a separate member for suppressing an occurrence of abnormal noise, and it is possible to manufacture anair conditioner 1 at low cost. - It is not necessary to enhance the manufacturing accuracy and reduce the clearance between the
shaft insertion hole 24 and the mainbody tube portion 41 in order to suppress an occurrence of abnormal noise. As a result, it is not necessary to excessively enhance the manufacturing accuracy of the connectingshaft 21, and it is possible to suppress the manufacturing costs of the connectingshaft 21. - When the clearance between the
shaft insertion hole 24 and the mainbody tube portion 41 is set to be small to suppress the occurrence of abnormal noise, the clearance is likely to become too narrow. As a result, the frictional force generated between theshaft insertion hole 24 and the mainbody tube portion 41 increases when theflap 8 is operated, and there is a possibility of occurrences of other failures such as a degradation of operability of the flap or a sliding sound. However, because it is not necessary to reduce the clearance between theshaft insertion hole 24 and the mainbody tube portion 41, it is possible to suppress the occurrence of such failures. - In a state in which the swelling
portion 33 abuts the innercircumferential surface 24f of theshaft insertion hole 24, thedistal end portion 30b side is pressed radially inward toward the central axis (axis O), and theelastic deformation piece 30 is elastically deformed. That is, it is possible to suppress the swellingportion 33 from coming into contact with the innercircumferential surface 24f of theshaft insertion hole 24, in a state in which the excessively large force is applied thereto. Accordingly, it is possible to suppress the frictional force generated between theelastic deformation piece 30 and the innercircumferential surface 24f of theshaft insertion hole 24 from becoming excessive, and it is possible to suppress the hindrance of smooth operation of theflap 8. In particular, only the swellingportion 33 formed at thedistal end portion 30b of theelastic deformation piece 30 comes into contact with the innercircumferential surface 24f of theshaft insertion hole 24. As a result, it is possible to further suppress the frictional force generated between theelastic deformation piece 30 and the innercircumferential surface 24f of theshaft insertion hole 24. - The
thin portion 31 is formed at theproximal end portion 30a of theelastic deformation piece 30, and the swellingportion 33 is formed to be thicker than thethin portion 31. As a result, it is possible to easily generate the elastic deformation in theelastic deformation piece 30. Therefore, it is possible to effectively generate the elastic force in the swellingportion 33. Accordingly, it is possible to more reliably suppress an increase in friction between theshaft insertion hole 24 and the shaftmain body 25 caused by pressing the swellingportion 33 against the innercircumferential surface 24f of theshaft insertion hole 24 by the excessive force. Further, it is possible to effectively perform the suppression of the rattling between theshaft insertion hole 24 and the connectingshaft 21 and the suppression of vibration of the connectingshaft 21 using theelastic deformation piece 30. - While the embodiments of the present invention have been described in detail, it is also possible to slightly change the design within the scope that does not depart from the technical idea of the present invention.
- For example, while the
thin portion 31 is formed on theproximal end portion 30a side of theelastic deformation piece 30, thethin portion 31 is not essential. - While the swelling
portion 33 is formed by forming thethick portion 32 on thedistal end portion 30b side of theelastic deformation piece 30, it is not limited thereto. Theelastic deformation piece 30 may be formed to have a constant thickness, theelastic deformation piece 30 may be formed so that an amount of protrusion from the outercircumferential surface 25f of the shaftmain body 25 toward the radially outer side increases from theproximal end portion 30a side toward thedistal end portion 30b side, and thedistal end portion 30b of theelastic deformation piece 30 may be caused to swell radially outward from the outercircumferential surface 25f of the shaftmain body 25. - A plurality of
elastically deformation pieces 30 formed on the shaftmain body 25 may be provided in the circumferential direction at intervals. - In the above-described embodiments, the
elastic deformation piece 30 is provided to extend in the direction of axis O of the shaftmain body 25, but it is not limited thereto. As illustrated inFIG. 8 , as a modified example, by forming a through hole 29B in the circumferential direction, an elastic deformation piece (an elastic deformation portion) 30B extending in the circumferential direction may be formed. In theelastic deformation piece 30B of the connectingshaft 21 of this modified example, theproximal end portion 30c is formed continuously and integrally with the mainbody tube portion 41. Theelastic deformation piece 30B is formed so that an amount of protrusion from the outercircumferential surface 25f of the shaftmain body 25 toward the radially outer side gradually increases from theproximal end portion 30c side toward thedistal end portion 30d side. - Even in the case of such a configuration, it is possible to obtain the same effect as the
elastic deformation piece 30 of the embodiment. - According to the air conditioner, it is possible to suppress the rattling between the main body side mounting hole and the connecting member and to suppress an occurrence of abnormal noise generated at the time of operation of the flap.
- While preferred embodiments of the invention have been described and illustrated above, it should be understood that these are exemplary of the invention and are not to be considered as limiting. Additions, omissions, substitutions, and other modifications can be made without departing from the technique spirit or scope of the present invention. Accordingly, the invention is not to be considered as being limited by the foregoing description, and is only limited by the scope of the appended claims.
