Description

[Technical Field]

[0001] The present invention relates to a vehicle ventilator. [Background technology]

[0002] Vehicle ventilators are installed in the instrument panel of vehicles such as automobiles. The vehicle ventilator is attached to an air outlet in the instrument panel and blows conditioned air from inside the instrument panel toward the passengers. The vehicle ventilator can change the direction of the conditioned air by tilting its position, for example, vertically.

[0003] Patent Document 1 describes an automobile ventilator that includes a case body and a box-shaped air outlet tube. Mounting holes and arc-shaped elongated holes are provided on both side walls of the case body. Support shafts and stoppers are provided on both outer surfaces of the air outlet tube.

[0004] In an automotive ventilator, a bearing piece is attached to a mounting hole in the case body, and the support shaft of the blow-out tube is fitted into the bearing piece, thereby supporting the blow-out tube within the case body so that it can rotate in a vertical plane. The blow-out tube stopper is inserted into an arc-shaped elongated hole in the case body, limiting the rotation range of the blow-out tube during rotation. The bearing piece is made of synthetic resin and is provided to apply appropriate frictional resistance to the support shaft of the blow-out tube during rotation, ensuring good operability.

[0005] As a result, in the automobile ventilator of Patent Document 1, the blowout tube is rotated around the support shaft of the blowout tube as a fulcrum, and the tilt angle is appropriately set, thereby making it possible to adjust the airflow direction up and down.

[0006] [Patent Document 1] Japanese Patent Application Publication No. 8-327133 Summary of the Invention [Problem to be solved by the invention]

[0007] In the automotive ventilator of Patent Document 1, in order to rotatably support the blowout tube within the case body, it is necessary to attach a bearing piece to the mounting hole of the case body and then fit the support shaft of the blowout tube into the bearing piece. However, if there is variation in the dimensions of the mounting hole of the case body or the bearing piece made of synthetic resin, the bearing piece will rattle, making it difficult to obtain a good operating feel when rotating the blowout tube.

[0008] Furthermore, if there is variation in the dimensions of the various components, such as the mounting holes in the case body, the bearing pieces, and the support shaft of the blow-out tube, it becomes difficult to assemble these components, which impairs workability.

[0009] In view of the above problems, the present invention aims to provide a vehicle ventilator that can absorb dimensional variations of components to improve workability during assembly and maintain a good operating feel. [Means for solving the problem]

[0010] In order to solve the above problems, a typical configuration of a vehicle ventilator according to the present invention is a vehicle ventilator having a case body that is inserted into an air outlet of an instrument panel of the vehicle and passes conditioned air from the inside of the instrument panel to the occupant side, the vehicle ventilator further having a rectangular recess that is recessed into the side portion of the case body in a side view, an elastic bush that is rectangular in a side view and fitted into the recess, and a shaft member that is fixed to the side wall of the air outlet and supports the case body and bush so that they can rotate freely around a rotation axis in the vehicle width direction, the bush having a rectangular outer frame portion that is held directly in the recess, a cylindrical inner tube portion that is located inside the outer frame portion and into which the shaft member is inserted, and a plurality of spoke portions that radially connect the outer frame portion and the inner tube portion to divide the space between the outer frame portion and the inner tube portion into a plurality of openings. [Effects of the Invention]

[0011] According to the present invention, it is possible to provide a vehicle ventilator that can absorb dimensional variations of components to improve workability during assembly and maintain a good operational feel. [Brief explanation of the drawings]

[Figure 6] 6 is a diagram showing a modified example of the vehicle ventilator of FIG. 5. DETAILED DESCRIPTION OF THE INVENTION

[0013] A typical configuration of a vehicle ventilator according to one embodiment of the present invention is a vehicle ventilator including a case body that is inserted into an air outlet of an instrument panel of the vehicle and passes conditioned air from the inside of the instrument panel to the occupant side, the vehicle ventilator further including a recess that is rectangular in side view and formed by being recessed into the side portion of the case body, a resilient bush that is rectangular in side view and fitted into the recess, and an axial member that is fixed to the side wall of the air outlet and supports the case body and bush rotatably around a rotation axis in the vehicle width direction, the bush having a rectangular outer frame portion that is held directly in the recess, a cylindrical inner tube portion that is located inside the outer frame portion and into which the axial member is inserted, and a plurality of spoke portions that radially connect the outer frame portion and the inner tube portion to divide the space between the outer frame portion and the inner tube portion into a plurality of openings.

[0014] In the above configuration, when the elastic rectangular bushing is fitted into the rectangular recess of the case body, the outer frame of the bushing contacts and is held in place in the recess of the case body. At this time, if there is variation in the dimensions of the recess of the case body or the outer frame of the bushing, the outer frame of the bushing is pressed from the outside toward the inside by the recess of the case body and deforms. This causes the outer frame of the bushing to deform and crush the opening, thereby absorbing the dimensional variation in the recess of the case body and the outer frame of the bushing. Therefore, with the above configuration, the bushing can be more reliably assembled into the recess of the case body, improving workability.

[0015] Furthermore, the inner cylindrical portion of the bushing is spaced inward from the outer frame portion via the spokes. Therefore, even if the bushing is fitted into a recess in the case body and the outer frame portion or spokes of the bushing are deformed, the inner cylindrical portion of the bushing will not deform. In other words, the insertion hole in the inner cylindrical portion of the bushing will not deform. Therefore, the rotation and sliding of the shaft member inserted into the insertion hole are not hindered. Therefore, with the above configuration, when rotating the case body around the axis of the shaft member to tilt the case body up or down, the operating force is less likely to vary, and a good operating feel can be maintained.

[0016] The outer frame and recess of the bush are square in side view.

[0017] This makes the bush symmetrical in both the vertical and horizontal directions due to the square outer frame, making it easier to align it with the square recess of the case body, thereby further improving the workability when assembling the bush into the recess of the case body.

[0018] The recess has a plurality of protrusions that protrude inward, and each of the plurality of protrusions is formed at a position that overlaps with one of the sides along the outer frame portion that forms the outside of the plurality of openings of the bush.

[0019] As a result, when the bushing is fitted into the recess of the case body, the protrusion of the recess of the case body presses the outer frame of the bushing inward, reliably deforming the opening. This makes it difficult for the bushing to come out of the recess of the case body. Furthermore, even if the outer frame of the bushing deforms, the inner cylinder does not, so rotation and sliding of the shaft member inserted into the insertion hole of the inner cylinder are not hindered.

[0020] The shaft member has a base, a rotating shaft portion extending from the base and inserted into the inner cylindrical portion of the bush, and a stopper extending from the base and inserted into one of the multiple openings in the bush, and the multiple protrusions of the recess press the outer frame portion of the bush inward, deforming it and causing multiple raised convex portions to appear inside the multiple openings, and when the case body rotates, the stopper of the shaft member comes into contact with one of the multiple convex portions that appear in one of the multiple openings, and moves over it to the multiple spoke portions.

[0021] As a result, when rotating the case body around the axis of the rotating shaft portion of the shaft member, the stopper of the shaft member moves to the spoke portion while contacting the convex portion appearing at the opening of the bushing and abuts against it. Therefore, the stopper of the shaft member and the convex portion of the opening of the bushing provide a feeling of operation (clicking sensation) during operation, and also reduce the sound that occurs when the shaft member and the bushing come into contact during operation. Furthermore, the height of the convex portion of the opening of the bushing can be easily adjusted by changing the height of the protruding portion of the recessed portion of the case body. Therefore, by changing the height of the protruding portion of the recessed portion of the case body, the feeling of operation when rotating the case body around the axis of the rotating shaft portion of the shaft member can be easily adjusted.

[0022] The plurality of protrusions of the recess are provided at positions that overlap the centers of the respective sides of the plurality of openings of the bush along the outer frame portion.

[0023] As a result, when the bushing is fitted into the recess of the case body, the outer frame of the bushing deforms, causing convex portions to appear regularly at predetermined intervals in the center of one side of the opening along the outer frame. Therefore, when the case body is rotated around the axis of the rotation shaft of the shaft member, the stopper of the shaft member comes into regular contact with the convex portions appearing in the opening of the bushing. This allows for a consistent feel during operation. Furthermore, the outer frame of the bushing is reliably deformed so as to cause convex portions to appear in the center of one side of each of the multiple openings along the outer frame. This allows the bushing to be reliably assembled into the recess of the case body, accommodating dimensional variations in the recess of the case body and the outer frame of the bushing, improving workability.

[0024] The shaft member has a base, a rotating shaft portion extending from the base and inserted into the inner cylindrical portion of the bush, and a stopper extending from the base and inserted into one of the multiple openings in the bush, and the bush further has multiple raised portions that protrude inside the multiple openings, and when the case body rotates, the stopper of the shaft member comes into contact with one of the multiple raised portions located in one of the multiple openings in the bush, moves over this and to one of the multiple spoke portions.

[0025] As a result, when rotating the case body around the axis of the rotating shaft portion of the shaft member, the stopper of the shaft member moves to the spoke portion while contacting the raised portion provided at the opening of the bushing and abuts against it. Therefore, the stopper of the shaft member and the raised portion at the opening of the bushing provide a sense of operation during operation and also reduce the sound that occurs when the shaft member and the bushing come into contact during operation. In addition, the height of the raised portion at the opening of the bushing can be easily adjusted. Therefore, by changing the height of the raised portion at the opening of the bushing, the sense of operation when rotating the case body around the axis of the rotating shaft portion of the shaft member can be easily adjusted. [Example]

[0026] Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Dimensions, materials, and other specific values shown in these embodiments are merely examples for facilitating understanding of the invention and, unless otherwise specified, do not limit the present invention. In this specification and drawings, elements having substantially the same functions and configurations are designated by the same reference numerals to avoid redundant explanation, and elements not directly related to the present invention are not shown.

[0027] 1 is a diagram schematically illustrating a vehicle ventilator 100 according to an embodiment of the present invention, together with an instrument panel 102. In the following drawings, the front and back directions of the vehicle are indicated by arrows Front and Back, the left and right directions of the vehicle width are indicated by arrows Left and Right, and the up and down directions of the vehicle are indicated by arrows Up and Down.

[0028] An instrument panel 102 of a vehicle is provided with an air outlet 104 through which conditioned air from an air conditioner (not shown) blows out. The vehicle ventilator 100 is attached to the air outlet 104 and adjusts the direction of the conditioned air.

[0029] Fig. 2 is an exploded perspective view showing the main parts of the vehicle ventilator 100 of Fig. 1. The vehicle ventilator 100 includes a case body 106, a bushing 108, and a shaft member 110. The case body 106 is tunnel-shaped with an opening in the front-to-rear direction of the vehicle, and is inserted into an air outlet 104 (see Fig. 1) of an instrument panel 102, allowing conditioned air to pass from the inside of the instrument panel 102 to the passenger side.

[0030] Thin horizontal plate fins 112 and vertical plate fins 114 span the inside of the case body 106. The horizontal plate fins 112 are arranged on the passenger side of the case body 106 and extend in the vehicle width direction from a side portion 116 of the case body 106. The vertical plate fins 114 are arranged behind the horizontal plate fins 112, i.e., on the front side of the vehicle, and extend in the vertical direction between an upper surface 118 and a lower surface 120 of the case body 106.

[0031] Case body 106 has a recess 122 that is rectangular (square in this case) in side view. Recess 122 is recessed into side surface 116 of case body 106. Bush 108 is an elastic member made of, for example, rubber, has a rectangular (square in this case) shape in side view, and is fitted into recess 122 of case body 106 (see FIG. 5). Therefore, the thickness of bush 108 in the vehicle width direction and the depth of recess 122 of case body 106 in the vehicle width direction are approximately the same dimension. In addition, shaft member 110 is fixed to a side wall 123 of air outlet 104 of instrument panel 102 shown in FIG. 1, and supports case body 106 and bush 108 rotatably about a rotation axis in the vehicle width direction.

[0032] Fig. 3 is a diagram showing the bushing 108 and the recessed portion 122 of the case body 106 of the vehicle ventilator 100 of Fig. 2. Fig. 3(a) is a side view of the bushing 108. Fig. 3(b) is an enlarged view of the recessed portion 122 of the case body 106 of Fig. 2.

[0033] 3(a), the bushing 108 has a square outer frame portion 124, a cylindrical inner tube portion 126, and a plurality of (four in this example) spoke portions 128, 130, 132, and 134, and these portions are, for example, integrally molded. When the bushing 108 is fitted into the recess 122 of the case body 106, the outer frame portion 124 is directly held in the recess 122. The inner tube portion 126 is located inside the outer frame portion 124, and an insertion hole 136 is formed inside the inner tube portion 126.

[0034] The spoke portions 128, 130, 132, and 134 each extend linearly to radially connect the outer frame portion 124 and the inner cylinder portion 126, and divide the space between the outer frame portion 124 and the inner cylinder portion 126 into a plurality of (here, four) openings 138, 140, 142, and 144. These openings 138, 140, 142, and 144 each have sides 145 and 146, sides 148 and 150, sides 152 and 154, and sides 156 and 158 that extend along the outer frame portion 124. The spoke portions 128, 130, 132, and 134 have the same length. The sides 145, 146, 148, 150, 152, 154, 156, and 158 also have the same length.

[0035] In the bushing 108, the radius of the insertion hole 136 of the inner cylindrical portion 126, i.e., the length from the center O, is defined as dimension La, the thickness of the inner cylindrical portion 126 is defined as dimension Lb, and the length of the representative spoke portion 130 is defined as dimension Lc. In this case, as an example, the dimensions La, Lb, Lc The lengths of the openings 138 are the same (i.e., La:Lb:Lc=1:1:1). The length of one side 146 of a representative opening 138 of the bushing 108 is defined as dimension Ld. In this case, as an example, dimension Ld is three times as long as dimension Lc (i.e., Ld:Lc=3:1).

[0036] As shown in FIG. 3(b), the recess 122 of the case body 106 has a plurality of (eight in this example) protrusions 160, 162, 164, 166, 168, 170, 172, and 174 that protrude inward. The protrusions 160 and 174 protrude downward from an upper wall 176 of the recess 122. The protrusions 162 and 164 protrude forward from a rear wall 178 of the recess 122. The protrusions 166 and 168 protrude upward from a lower wall 180 of the recess 122. The protrusions 170 and 172 protrude rearward from a front wall 182 of the recess 122.

[0037] Fig. 4 is a view showing the shaft member 110 of the vehicle ventilator 100 of Fig. 2. Fig. 4(a) is a view showing a state in which the shaft member 110 is fixed to a side wall 123 of the air outlet 104 of the instrument panel 102. Fig. 4(b) is a view seen from the arrow A in Fig. 4(a), showing only the shaft member 110.

[0038] The shaft member 110 has a base 184, a rotating shaft 186, and a stopper 188. The rotating shaft 186 extends from the base 184 toward the bushing 108 as shown in FIG. 2, is inserted into an insertion hole 136 of the inner cylindrical portion 126 of the bushing 108 (see FIG. 5), and is rotatable relative to the insertion hole 136. The stopper 188 extends from the base 184 toward the bushing 108 and is inserted into one of the plurality of openings 138, 140, 142, and 144 of the bushing 108 (here, opening 138) (see FIG. 5). Note that the stopper 188 is spaced apart from the rotating shaft 186 as shown in FIG. 4(b).

[0039] 2, the shaft member 110 further has a fixing portion 190. The fixing portion 190 extends from the base portion 184 toward the opposite side of the bush 108. As shown in FIG. 4(a), the fixing portion 190 is inserted into a fixing hole 191 formed in the side wall 123 of the air outlet 104 of the instrument panel 102 and fixed thereto. In this way, the shaft member 110 is fixed to the side wall 123 of the air outlet 104, and can support the case body 106 and the bush 108 rotatably about a rotation axis in the vehicle width direction.

[0040] In the vehicle ventilator 100, for example, the bush 108 is fitted into the recess 122 of the case body 106, and the case body 106 and the bush 108 are rotatably supported by the shaft member 110. Shaft The fixing portion 190 of the member 110 is inserted into the fixing hole 191 in the side wall 123 of the air outlet 104 and fixed. In this manner, the vehicle ventilator 100 is attached to the air outlet 104 of the instrument panel 102.

[0041] FIG. 5 is a diagram showing the vehicle ventilator 100 of FIG. 2 in a state where the case body 106, the bushing 108, and the shaft member 110 are assembled.

[0042] The protrusions 160, 162, 164, 166, 168, 170, 172, and 174 of the recess 122 of the case body 106 are formed at positions overlapping one side along the outer frame portion 124 that forms the outside of the multiple openings 138, 140, 142, and 144 of the bushing 108, as shown in the figure.

[0043] That is, protrusions 160 and 162 are provided at positions overlapping with centers B and C of sides 145 and 146 of opening 138 of bushing 108 along outer frame portion 124. Protrusions 164 and 166 are provided at positions overlapping with centers D and E of sides 148 and 150 of opening 140 along outer frame portion 124.

[0044] Furthermore, protrusions 168, 170 are provided at positions overlapping with centers F, G of sides 152, 154 of opening 142 along outer frame portion 124. Protrusions 172, 174 are provided at positions overlapping with centers H, I of sides 156, 158 of opening 144 along outer frame portion 124.

[0045] In vehicle ventilator 100, when elastic square bushing 108 is fitted into square recess 122 of case body 106, outer frame 124 of bushing 108 is held in contact with recess 122 of case body 106. At this time, if there is variation in the dimensions of recess 122 of case body 106 and the dimensions of outer frame 124 of bushing 108, outer frame 124 of bushing 108 is pressed from the outside toward the inside by recess 122 of case body 106, and is deformed. Here, protrusions 160, 162, 164, 166, 168, 170, 172, 174 of recess 122 press outer frame 124 of bushing 108 inward, causing it to deform.

[0046] The protrusions 160 and 162 cause convex portions 192 and 193 to protrude inward from centers B and C of sides 145 and 146 of the opening 138 along the outer frame portion 124. The protrusions 164 and 166 cause convex portions 194 and 195 to protrude inward from centers D and E of sides 148 and 150 of the opening 140 along the outer frame portion 124.

[0047] Furthermore, protrusions 168, 170 cause convex portions 196, 197 to appear that bulge inward from centers F, G of sides 152, 154 of opening 142 that run along outer frame portion 124. Protrusions 172, 174 cause convex portions 198, 199 to appear that bulge inward from centers H, I of sides 156, 158 of opening 144 that run along outer frame portion 124.

[0048] In this way, outer frame portion 124 of bushing 108 deforms, and openings 138, 140, 142, and 144 deform reliably, thereby absorbing dimensional variations in recess 122 of case body 106 and outer frame portion 124 of bushing 108. Therefore, in vehicle ventilator 100, bushing 108 can be more reliably assembled into recess 122 of case body 106, improving workability.

[0049] Furthermore, the openings 138, 140, 142, 144 of the bushing 108 are reliably deformed by the protrusions 160, 162, 164, 166, 168, 170, 172, 174 of the recess 122 of the case body 106, making it difficult for the bushing 108 to come off the recess 122 of the case body 106.

[0050] Furthermore, the inner cylindrical portion 126 of the bushing 108 is spaced inward from the outer frame portion 124 via the spoke portions 128, 130, 132, and 134. Therefore, even if the bushing 108 is fitted into the recess 122 of the case body 106 and the outer frame portion 124 or the spoke portions 128, 130, 132, and 134 are deformed, the inner cylindrical portion 126 will not deform. In other words, the insertion hole 136 of the inner cylindrical portion 126 of the bushing 108 will not deform. Therefore, the rotation and sliding of the shaft member 110 inserted into the insertion hole 136 will not be hindered.

[0051] Therefore, according to the vehicle ventilator 100, when rotating the case body 106 around the axis of the shaft member 110 and tilting the attitude of the case body 106 in the vertical direction, the operating force is less likely to vary, and a good operating feel can be maintained.

[0052] The outer frame 124 of the bushing 108 and the recess 122 of the case body 106 are square in side view. Therefore, the square outer frame 124 makes the bushing 108 symmetrical in the vertical and horizontal directions, making it easier to align the bushing 108 with the square recess 122 of the case body 106. This further improves the workability when assembling the bushing 108 into the recess 122 of the case body 106.

[0053] 5, stopper 188 of shaft member 110 is inserted into opening 138 of bushing 108. Therefore, in vehicle ventilator 100, when case body 106 is rotated around the axis of rotating shaft portion 186 of shaft member 110, stopper 188 comes into contact with protrusions 192, 193 that appear in opening 138 of bushing 108. Then, stopper 188 moves over protrusions 192, 193, moves between spoke portions 128, 130, and comes into contact with spoke portions 128, 130 (see arrow J).

[0054] Therefore, the stopper 188 of the shaft member 110 and the protrusions 192, 193 appearing in the opening 138 of the bush 108 provide a feeling of operation (click feeling) during operation, and furthermore, can also reduce the sound when the shaft member 110 and the bush 108 hit each other during operation.

[0055] Furthermore, because protrusions 192, 193 bulge inward from centers B, C of sides 145, 146 of opening 138 along outer frame portion 124, their positions are regular. As a result, when case body 106 is rotated, stopper 188 of shaft member 110 regularly contacts protrusions 192, 193 that appear in opening 138 of bushing 108. This allows for a consistent feel during operation.

[0056] Furthermore, the height of the convex portions 192, 193 of the opening 138 of the bushing 108 can be easily adjusted by changing the height of the protruding portions 160, 162 of the recessed portion 122 of the case body 106. Therefore, by changing the height of the protruding portions 160, 162 of the recessed portion 122 of the case body 106, the operational feel when rotating the case body 106 around the axis of the rotation shaft portion 186 of the shaft member 110 can be easily adjusted.

[0057] In the above-described vehicle ventilator 100, the stopper 188 of the shaft member 110 is inserted into the opening 138 of the bushing 108. However, the present invention is not limited to this. As an example, the bushing 108 having the square outer frame 124 may be rotated 90 degrees, the bushing 108 may be fitted into the recess 122 of the case body 106, and the stopper 188 of the shaft member 110 may be inserted into one of the other openings 140, 142, and 144. Even in this case, the stopper 188 moves and abuts between the spokes 130 and 132, between the spokes 132 and 134, and between the spokes 128 and 134 while contacting the protrusions 194, 195, 196, 197, 198, and 199 of the other openings 140, 142, and 144. This allows for a good operational feel when rotating the case body 106.

[0058] Figure 6 is a diagram showing a modified example of the vehicle ventilator 100 of Figure 5. The modified vehicle ventilator 100A differs from the above-described vehicle ventilator 100 in the following points: First, the above-described protrusions 160, 162, 164, 166, 168, 170, 172, and 174 are not formed on the upper wall 176A, rear wall 178A, lower wall 180A, and front wall 182A of the recess 122A of the case body 106A.

[0059] Next, the bushing 108A is provided with a plurality of raised portions 192A, 193A, 194A, 195A, 196A, 197A, 198A, and 199A instead of the plurality of convex portions 192, 193, 194, 195, 196, 197, 198, and 199 that appear due to the above-mentioned protrusions 160, 162, 164, 166, 168, 170, 172, and 174.

[0060] In such vehicle ventilator 100A, raised portions 192A and 193A are formed by protruding inward from centers B and C of sides 145A and 146A of opening 138A that run along outer frame portion 124A. Raised portions 194A and 195A are formed by protruding inward from centers D and E of sides 148A and 150A of opening 140A that run along outer frame portion 124A.

[0061] Furthermore, raised portions 196A and 197A bulge inward from centers F and G of sides 152A and 154A of opening 142A that run along outer frame portion 124A. Raised portions 198A and 199A bulge inward from centers H and I of sides 156A and 158A of opening 144A that run along outer frame portion 124A.

[0062] In vehicle ventilator 100A, when case body 106A is rotated around the axis of rotation shaft portion 186 of shaft member 110, stopper 188 comes into contact with raised portions 192A, 193A provided in opening 138A of bushing 108A. Stopper 188 then moves over raised portions 192A, 193A, moves between spoke portions 128, 130, and comes into contact with spoke portions 128, 130 (see arrow J).

[0063] Therefore, stopper 188 of shaft member 110 and raised portions 192A, 193A provided at opening 138A of bush 108A provide a clicking sensation during operation, and also reduce the sound made when shaft member 110 and bush 108A come into contact during operation.

[0064] Furthermore, because raised portions 192A and 193A bulge inward from centers B and C of sides 145A and 146A of opening 138A that are aligned along outer frame portion 124A, their positions are regular. As a result, when case body 106A is rotated, stopper 188 of shaft member 110 comes into regular contact with raised portions 192A and 193A provided on opening 138A of bushing 108A. This allows for a consistent feel during operation.

[0065] Furthermore, the height of raised portions 192A and 193A provided at opening 138A of bushing 108A can be easily adjusted. Therefore, by changing the height of raised portions 192A and 193A at opening 138A of bushing 108A, the operational feel when rotating case body 106A around the axis of rotation shaft portion 186 of shaft member 110 can be easily adjusted.

[0066] Furthermore, in vehicle ventilator 100A, when elastic bushing 108A is fitted into recess 122A of case body 106A, outer frame portion 124A of bushing 108A is held in contact with recess 122A of case body 106A. At this time, if there is variation in the dimensions of recess 122A of case body 106A and outer frame portion 124A of bushing 108A, outer frame portion 124A of bushing 108A will be pressed from the outside toward the inside by recess 122A of case body 106A and will be deformed.

[0067] Therefore, in vehicle ventilator 100A, dimensional variations in recess 122A of case body 106A and outer frame portion 124A of bushing 108A can be absorbed, and further, bushing 108A can be reliably assembled into recess 122A of case body 106A, thereby improving the workability of assembly.

[0068] Furthermore, in vehicle ventilator 100A, bushing 108A is fitted into recess 122A of case body 106A, and even if outer frame portion 124A and spoke portions 128, 130, 132, and 134 are deformed, inner cylinder portion 126 is not deformed. In other words, insertion hole 136 of inner cylinder portion 126 of bushing 108A is not deformed. Therefore, rotation and sliding of shaft member 110 inserted into insertion hole 136 are not hindered.

[0069] Therefore, according to the vehicle ventilator 100A, when rotating the case body 106A around the axis of the shaft member 110 to tilt the attitude of the case body 106A in the vertical direction, the operating force is less likely to vary, and a good operating feel can be maintained.

[0070] In the above-described vehicle ventilator 100, 100A, the outer frame portions 124, 124A of the bushings 108, 108A and the recesses 122, 122A of the case bodies 106, 106A are square in side view, but are not limited to this. That is, as long as the outer frame portions 124, 124A are directly held in the recesses 122, 122A with the bushings 108, 108A fitted in the recesses 122, 122A, and further the inner cylinder portions 126 of the bushings 108, 108A are set in an appropriate position, the outer frame portions 124, 124A and the recesses 122, 122A are not limited to square, and may be rectangular, for example.

[0071] While the preferred embodiments of the present invention have been described above with reference to the accompanying drawings, it goes without saying that the present invention is not limited to such examples. It is clear that those skilled in the art can conceive of various modifications and alterations within the scope of the claims, and it is understood that such modifications and alterations also fall within the technical scope of the present invention. [Industrial Applicability]
