The fins 23a of the movable fins 23 are arranged in the vertical direction at predetermined intervals on the left and right, and are pivotally supported by the support shafts 23b and 23e, respectively. Each fin 23a is provided with a support shaft 23b on the lower side of the front portion of the fin body, and a shaft hole 23d on the upper side of the front portion. As shown in FIG. 3, the support shaft 23e inserted into the shaft hole 23d at the upper portion of each fin 23a protrudes from the inside of the barrel main body 21, and the shaft hole 23d on the fin 23a side is inserted into the support shaft 23e. .

  Further, as shown in FIG. 5, each fin 23a is provided with a connecting shaft 23c shifted to an arm portion protruding on the right side, and the connecting shaft 23c of these seven fins 23a is a single link bar. 24, the seven fins 23a are synchronously rotated at the same angle via the link bar 24. Further, the operation knob 9 is fitted to the front side of the fin 23a located in the center, and the operation knob 9 is operated to rotate the fin 23a left and right around the support shafts 23b and 23e to change the wind direction to the left and right. Configured to change direction. In addition, the barrel 2 can be rotated up and down with the operation knob 9.

It fits in the provided spindle 23e. Then, the bearing frame portion 22 is fitted into the lower portion of the barrel body 21 from the lower side of the fins 23a. At this time, the shaft holes 22a of the bearing frame portion 22 are fitted into the lower support shafts 23b of the fins 23a. The engaging portions 22 b on both sides of the bearing frame portion 22 are engaged with the claws provided on the side 21 a of the barrel main body 21, and the bearing frame portion 22 is fitted to the lower portion of the barrel main body 21.

  Thus, the barrel 2 is assembled with the movable fin 23 pivotally supported inside the barrel main body 21. When the barrel 2 is assembled in the retainer 1 and the bezel 3, the bezel 3 is put on the front portion of the retainer 1 with the rotating shafts 27 on both sides of the barrel 2 fitted in the bearing portions 13 in the retainer 1. The bezel 3 is fitted so that the two pairs of upper and lower engaging portions 32 of the bezel are engaged with the engaging portions 14 on the retainer 1 side.

  Thereby, the barrel 2 is attached to the inside of the retainer 1 and the bezel 3 so as to be pivotable up and down via the pivot shafts 27 on both sides, and the register is assembled. As a result, as shown in FIGS. 1 and 3, when air is blown, the opening 21c of the barrel 2 is opened to the front, and when the barrel 2 is rotated downward to the rotation limit, as shown in FIG. The two closing portions 26 can close the air outlet 31 of the bezel 3. A soft sealing material 19 is attached to the outer peripheral portion of the back surface of the retainer 1 so that the back surface portion of the retainer 1 can be fitted into a ventilation duct disposed on a ceiling side wall of a passenger compartment (not shown) without a gap.

  The register having the above-described configuration is attached in the horizontal direction (lateral direction) by fitting the retainer 1 into an opening of a ventilation duct disposed on a ceiling side wall or the like of a vehicle cabin.

  As shown in FIGS. 3 and 4, when air is sent through the ventilation duct in a state where the opening 21 c of the barrel 2 faces front and the air outlet 31 is opened, the air that has reached the register is retained by the retainer 1. The air flows in the barrel 2 from the ventilation path 11 and is blown from the air outlet 31 to the front side. The blowing is guided by the fins 2a of the barrel 2 and the movable fins 23, and air is blown out in the direction in which the barrels 2 and the fins 23a face. When the air blowing direction is changed to the left and right direction, the wind direction is adjusted by holding the operation knob 9 and swinging the fins 23a to the left and right.

  When changing the blowing direction up and down, the dial part 28 provided on the side part of the barrel 2 is operated to rotate the barrel 2 upward or downward. Thereby, the direction of the opening 21c of the barrel 2 is adjusted upward or downward, and the direction of the wind is changed upward or downward.

  On the other hand, when the air outlet 31 is closed to block air blowing, the barrel 2 is turned downward with the operation knob 9 or the like, and the barrel 2 is turned to the lower turning limit. By this turning operation, as shown in FIGS. 8 and 9, the barrel 2 is brought into a state in which the plate-like closing portion 26 is positioned inside the air outlet 31, and the closing portion 26 moves the air outlet 31 from the inside. Close. Thereby, the ventilation supplied through the ventilation path 11 is interrupted | blocked.

  In order to avoid frictional resistance due to contact of the wall surface during barrel rotation between the outer surface of the side wall 21a on which the rotation shaft 27 of the barrel 2 projects and the side wall 33 of the bezel 3 during such closing, Since a slight gap occurs, wind leakage is likely to occur from this gap.

  However, as described above, the first wind leakage prevention rib 25 is provided on the side wall 21 a of the barrel 2, and the step portion 34 faces the first wind leakage prevention rib 25 on the inner side of the side wall 33 of the bezel 3. It is provided along the wind leak prevention rib 25 and is formed so that the first wind leak prevention rib 25 and the stepped portion 34 overlap each other.

  For this reason, when closed, the gap between the side wall 21a and the side wall 33 is refracted due to the overlap between the first air leakage prevention rib 25 and the stepped portion 34, and the side wall 21a of the barrel 2 and the bezel 3 are bent. Even if there is a gap between the side walls 33, wind leakage flowing through the gap is greatly suppressed and prevented. Further, since the fine uneven portion 25a is continuously formed on the first wind leakage prevention rib 25, even when a wind leak occurs due to a slight gap, the uneven operation of the air flow is prevented by the uneven portion 25a. The occurrence of wind noise due to wind leakage can be prevented.

  Further, as shown in FIG. 9, the second air leakage prevention rib 29 at the edge of the closed portion 26 overlaps with the inner edge of the air outlet 31 of the bezel 3 when closed, so that the gap can be effectively closed. Even when the barrel 2 or the bezel 3 has a dimensional error for each product and a gap is likely to be generated in the vicinity of the air outlet 31 when the barrel 2 is closed, the second wind leakage prevention rib 29 causes a gap. Can be minimized.

  Further, fine uneven portions 29 a (FIG. 7) are continuously formed on the second wind leakage prevention rib 29. For this reason, even when a wind leak occurs due to a slight gap, the resonance action of the air flow is blocked by the concavo-convex portion 29a, and the generation of wind noise due to the wind leak can be prevented. Further, as shown in FIG. 9, the uneven portion 35 is also formed along the edge portion on the inner edge portion of the air outlet 31 of the bezel 3. The resonance effect of the flow is blocked, and the generation of wind noise due to wind leakage can be prevented.
