It is overlapped under vertical view for its front end with the entrance 125a of throttling flow path 125.
Also, it in the upper end and lower end of the first guide vane 1261 and the second guide vane 1262, is formed with
Vertically columned rotation axis 133 outstanding.The upper and lower end of each rotation axis 133 by flow path 128 in pipeline wall
Surface bearing.The first guide vane 1261 and the second guide vane 1262 rotate certainly centered on each rotation axis 133 as a result,
Such as.
The air stream generated by pressure fan 112 is imported into the inside of pipeline 12 via the blow-off outlet 111b of case 111.In pipe
The air stream that flow path 128 flows in the pipeline of the inside in road 12 has the flow velocity components of front direction and right direction.But when leading
When being in state as shown in FIG. 6 to blade 126, air stream loses the right side by the lateral surface flowing along guide vane 126
The flow velocity components in direction.The flow direction of air stream becomes the direction substantially parallel with front-rear direction as a result, and is imported into throttling flow path
125 entrance 125a.
The air stream of entrance 125a is imported by flowing via throttling flow path 125 to blow-off outlet 120, flow velocity improves.
Since the air stream of flow path 128 in pipeline is to flow into entrance 125a with the substantially parallel flow direction of front-rear direction, inertia is relied on,
It keeps with the substantially parallel flow direction of front-rear direction and by throttling flow path 125, and is blown out rearward from blow-off outlet 120.Therefore,
The flow direction of the air stream blown out rearward from blow-off outlet 120 becomes the direction substantially parallel with front-rear direction.From blow-off outlet 120
The air stream of blowout is by the first air stream F11 blown out from the first blowing portion 121 and the second sky blown out from the second blowing portion 122
Air-flow F21 composition.
Firstly, the first air stream F11 and the second air stream F21 that blow out rearward from blow-off outlet 120 pass through Condar
Effect and along the downside of pipeline 12 127 flow.That is, the downside 127 of pipeline 12 and the downside of aftermentioned outer flap 141
Face 141a constitutes the guide surface GS for making air stream along flowing.
When the first air stream F11 and the second air stream F21 is blown out from blow-off outlet 120, the air of surrounding is attracted
And form secondary air streams F41, F51.As a result, the first air stream F11 and the second air stream F21 and secondary air streams F41,
The interflow F51, flow are alonged the downside 127 of pipeline 12 while increasing and are flowed rearward.
Here, as previously mentioned, the first blowing portion 121 is set to than the second blowing portion 122 closer to flow path 128 in pipeline
112 side of upstream side, that is, pressure fan.Therefore, it is fed into the air stream of the first blowing portion 121 and is fed into the second blowing portion 122
Air stream compare, do not allow to be also easy to produce the pressure loss during being supplied to from pressure fan 112.Therefore, it is fed into
The pressure that the pressure ratio of the air stream of one blowing portion 121 is fed into the air stream of the second blowing portion 122 is high.
Also, in five guide vanes 126, the size of the first guide vane 1261 in the longitudinal direction is than the second directing vane
The size of piece 1262 in the longitudinal direction is big.As a result, compared to the second guide vane 1262, the first guide vane 1261 makes more
Air stream flowed along its lateral surface and be directed to the first interconnecting part 1251.Therefore, the first guide vane 1261 is so that by supplying
The high mode of the pressure for the air stream that the pressure ratio for being given to the air stream of the first blowing portion 121 is fed into the second blowing portion 122
It plays a role.
In addition, in throttling flow path 125, the sectional area ratio for the first interconnecting part 1251 being connected to the first blowing portion 121 and the
The sectional area of second interconnecting part 1252 of two blowing portion 122 connection is small.Therefore, is fed by the first interconnecting part 1251
The pressure of the air stream of one blowing portion 121 is further than being fed into the second blowing portion 122 by the second interconnecting part 1252
The pressure of air stream is high.
As described above, the pressure of the air stream of the first blowing portion 121 of blow-off outlet 120 is fed by improving, from
The flow velocity of first air stream F11 of the first blowing portion 121 blowout becomes the second air stream than blowing out from the second blowing portion 122
The flow velocity of F21 is big.
As shown in Figures 2 to 4, the first air stream F11 blown out rearward from the first blowing portion 121 of blow-off outlet 120
After being flowed by Coanda effect along the downside 127 of pipeline 12, the direction in the downside 127 along pipeline 12 is enterprising
One step is flowed to the rear side of pipeline 12.First air stream F11 flows through the portion of the central portion close to compartment VC in the lateral direction
The position (first position) divided and be fed into where occupant P3.
On the other hand, it as shown in Fig. 2, Fig. 3 and Fig. 5, is blown out rearward from the second blowing portion 122 of blow-off outlet 120
The second air stream F21 by Coanda effect along pipeline 12 downside 127 flow after, then along outer flap 141
Downside 141a flowing.Pass through outer flap 141 inclined in a manner of extending downward, the flow direction of the second air stream F21
Side changes forwards, and is fed into the position (second position) where occupant P2.
Like this, the flow velocity of the air stream of the blowout of air supply device 10 involved in first embodiment is according to blow-off outlet 120
Position and it is different.That is, being configured to the first air stream blown out from i.e. the first blowing portion 121 in the position of closer pressure fan 112
The flow velocity of the velocity ratio of F11 from the second air stream F21 that i.e. the second blowing portion 122 in the position further away from pressure fan 112 is blown out are big.
Therefore, the air supply device 10 according to involved in the first embodiment, by making lesser second air stream of flow velocity
Position where F21 towards occupant P2 and make the biggish first air stream F11 of flow velocity towards the position where occupant P3, it can
The air stream of sufficient flow is also supplied with to occupant P3.Thereby, it is possible to simultaneously to the occupant for being located at different location in the longitudinal direction
P2, P3 supply the air stream of sufficient flow.
Air supply device 10A involved in the variation of first embodiment is directed at while referring to Fig. 7 to be illustrated.
Air supply device 10 involved in the structure and above-mentioned first embodiment of the inside of the pipeline 12A of air supply device 10A
Pipeline 12 it is different.Therefore, identical symbol is added for the structure being the same as the above first embodiment and suitably omitted
Explanation.
The flow path 128A in the pipeline of the inside of pipeline 12, five the second guide vanes 1262 are configured between being mutually spaced apart
Every and linear arrangement in the lateral direction.This five the second guide vanes 1262 are so that air stream flows simultaneously along its lateral surface
The mode of the first blowing portion 121 and the second blowing portion 122 that are directed to blow-off outlet 120 plays a role.
Also, pipeline 12A flow path 128A in its pipeline has wall body 129.In the lateral direction, the wall body 129 is to incite somebody to action
The boundary of first blowing portion 121 and the second blowing portion 122 is formed as side forwards as the mode on vertex and protrudes.
By in the pipeline of pipeline 12A flow path 128A such wall body 129 is set, by from 112 import pipe of pressure fan
The air stream of interior flow path 128A is flowed along wall body 129.The air stream of flow path 128A is directed into blowout mostly in pipeline as a result,

The pressure for being given to the air stream of the second blowing portion 122 is high.
As described above, the pressure of the air stream of the first blowing portion 121 of blow-off outlet 120 is fed by improving, from
The flow velocity of first air stream F11 of the first blowing portion 121 blowout becomes than blowing out the second air stream F21 from the second blowing portion 122
Flow velocity it is big.
Therefore, air supply device 10A involved in the variation of the first embodiment also can be by keeping flow velocity lesser
Second air stream F21 is towards the position where occupant P2 and makes the biggish first air stream F11 of flow velocity towards the place occupant P3
Position be also supplied with the air stream of sufficient flow to occupant P3.Thereby, it is possible to simultaneously in the longitudinal direction positioned at different positions
Occupant P2, the P3 set supplies the air stream of sufficient flow.
On one side referring to Fig. 8 and Fig. 9, air supply device 10B involved in second embodiment is illustrated on one side.This
In the structure of air supply device 10B involved in two embodiments, blow-off outlet 120B, inner flap 142, intermediate fins 143 with
And it is different from air supply device 10 involved in above-mentioned first embodiment at outer flap 144.Therefore, for being filled with above-mentioned air-supply
It sets 10 identical structures and adds identical symbol and description is omitted as appropriate.
The position of downside 127 in the pipeline 12 of air supply device 10B and the front end close to pipeline 12, is formed with a left side
Right direction is the blow-off outlet 120B of the slit-shaped of length direction.Blow-off outlet 120B is by the first blowing portion 121B, third blowing portion
123B and the second blowing portion 122B is constituted, and in the lateral direction, the first blowing portion 121B is proximate to the position of pressure fan 112,
Third blowing portion 123B is proximate to the position of the end of compartment VC, and the second blowing portion 122B is that the first blowing portion 121B and third are blown
Position between portion 123B out.Also, blow-off outlet 120B is the first blowing portion 121B, the second blowing portion 122B and third blowout
Portion 123B connected single opening.
Inner flap 142, intermediate fins 143 and outer flap 144 are that size in the lateral direction compares blow-off outlet
The small flat component of the size of 120B in the lateral direction.Also, inner flap 142 and outer flap 144 are in right and left
The sum of upward size is set to bigger than the size of intermediate fins 143 in the lateral direction.
Inner flap 142, intermediate fins 143 and outer flap 144 are configured at the outside of pipeline 12, and their pipe
The one end of 12 side of road is supported by the rotation axis 140 extended substantially horizontally in the lateral direction.Inner flap 142, centre as a result,
Fin 143 and outer flap 144 can be rotated freely and static at an arbitrary position centered on rotation axis 140.

Fin) it is configured at the rear of the second blowing portion 122B.In addition, outer flap 144 (third fin) is configured at third blowing portion
The rear of 123B.
Since the air stream of flow path 128 in pipeline is to flow into entrance 125a with the substantially parallel flow direction of front-rear direction,
By inertia, air stream keep with front-rear direction it is substantially parallel flow through throttling flow path 125, and from the blow-off outlet of pipeline 12
120B is rearward blown out.Therefore, become substantially flat with front-rear direction from the flow direction of the blow-off outlet 120B air stream rearward blown out
Capable direction.The air stream blown out from blow-off outlet 120B by blown out from the first blowing portion 121B the first air stream F12, from second
Second air stream F22 of blowing portion 122B blowout and the third air stream F32 composition blown out from third blowing portion 123B.
When the first air stream F12, the second air stream F22 and third air stream F32 are blown out from blow-off outlet 120B, week
The air enclosed is attracted and forms secondary air streams F42, F52, F62.As a result, the first air stream F12, the second air stream F22
And third air stream F32 and secondary air streams F42, F52, F62 collaborate, flow is alonged while increasing under pipeline 12
It flows rearward side 127.
In blow-off outlet 120B, blown out near the first blowing portion 121B and the second blowing portion 122B of pressure fan 112, third
Portion 123B is compared, and the pressure for being configured to the air stream being supplied to is high.Also, than third blowing portion 123B closer to pressure fan 112
The second blowing portion 122B be configured to high compared to the pressure of the third blowing portion 123B air stream being supplied to.
Therefore, it is blown out from the velocity ratio of the first blowing portion 121B the first air stream F12 blown out from the second blowing portion 122B
The second air stream F22, from third blowing portion 123B blow out third air stream F32 flow velocity it is big.In addition, the second air stream
