  As shown in FIGS. 18 and 20, the deformed shaft hole 39 of the second bevel gear member 38 has a contact surface 39a with which the flat surface 47a of the ball shaft member 46 fitted therein contacts at the rotating end. Sliding contact surfaces 39b that are provided on both sides and with which the arcuate curved surface 47b is slidable are provided on both sides. As shown in FIG. 20A, the contact surfaces 39a of the deformed shaft hole 39 are formed on both sides with an inclination angle of, for example, 30 ° with respect to the center line S3.

  Accordingly, when the operation unit 6 starts to rotate to the right from the neutral state (open state) in FIG. 5, the ball shaft member 46 is in the second state as shown in FIGS. 20 (a) to 20 (b). When the bevel gear member 38 starts idling and is rotated by an angle of 30 °, the flat surface 47 a of the end fitting portion 47 of the ball shaft member 46 contacts the contact surface 39 a of the deformed shaft hole 39. When the operation unit 6 is further rotated, as shown in FIGS. 20 (b) to 20 (c), the turning force of the ball shaft member 46 is transmitted to the second bevel gear member 38, and the second bevel gear member is transmitted. 38 is rotated to transmit the rotational force of the operation unit 6 to the damper device 30.

  As described above, the end fitting portion 47 of the ball shaft member 46 is fitted into the deformed shaft hole 39 of the second bevel gear member 38. As shown in FIGS. A spring member 38a (coil spring) that urges the second bevel gear member toward the ball joint support portion 11 is attached to 47 via a spring seat 38b. The lid-like spring seat 38b is fixed to the end face of the end fitting portion 47 by a mounting screw 38c.

  As a result, the second bevel gear member 38 is biased toward the ball joint support portion 11 by the spring member 38 a, and causes an appropriate frictional resistance to the ball joint support portion 11. As a result, at the initial stage of the turning operation of the operation unit 6, the rotation is suppressed and only the ball shaft member 46 is idled, and then the rotational force of the ball shaft member 46 is changed to the first as shown in FIG. It transmits to the 2 bevel gear member 38, and the 2nd bevel gear member 38 is rotated.

  As shown in FIGS. 13 to 16, the damper device 30 is configured to have a pair of semicircular dampers 31, 32 each having a shaft portion 33, 35 provided on a straight portion so as to be rotatable. Second bevel gear pieces 36, 37 that mesh with the second bevel gear member 38 are integrally formed on the shaft portions 33, 35 of the straight portions of the semicircular dampers 31, 32.

  As shown in FIG. 16, the shaft portions 33, 35 provided on the straight portions of the pair of semicircular dampers 31, 32 have a connecting shaft 33 a protruding from the axial center position of one shaft portion 33, and the other shaft portion. A connecting hole is provided at the 35 axial support positions. Similarly, a connecting shaft 35a protrudes from the axial position of the other shaft portion 35, a connecting hole is provided at the shaft support position of the one shaft portion 33, and the connecting shaft 35a is inserted into the connecting hole. The circular dampers 31 and 32 are connected to the rear surface side through the shaft portions 33 and 35 of the linear portions so as to be rotatable in an angle range of about 90 °.

  As shown in FIG. 5, the pair of semicircular dampers 31 and 32 that are assembled are engaged with the second bevel gear member 38 of the second bevel gear mechanism 34, as shown in FIG. 5. When the rotational force from the operation unit 6 is transmitted to the second bevel gear member 38, the rotating portion 15 is rotated about the shaft portions 33 and 35 in the opposite direction in an angle range of about 90 °, and the ventilation path 15 is opened or closed. Will be.

  As shown in FIG. 16, the pair of semicircular dampers 31 and 32 of the damper device 30 has support shafts 33b and 35b protruding vertically at the end portions of the shaft portions 33 and 35, and the support shafts 33b and 35b are As shown in FIG. 5, the retainer 1 is fitted into bearing holes provided in the upper and lower portions and is pivotally supported. Further, as shown in FIG. 24, soft synthetic resin portions 31a and 32a are formed on at least the arc-shaped edges of the pair of semicircular dampers 31 and 32, respectively. When the soft synthetic resin portions 31a and 32a are fully closed, the soft synthetic resin portions 31a and 32a abut against the inner peripheral wall of the air passage 15 to prevent wind leakage and improve the fully closed performance.

  As described above, the damper device 30 opens the ventilation path 15 in a state where the pair of semicircular dampers 31 and 32 are rotated to a state parallel to the ventilation direction, as shown in FIG. Basically, when the operation unit 6 is rotated to the right, for example, from the opened state, the damper device 30 closes the pair of semicircular dampers 31 and 32 from a predetermined angular position of the operation unit 6. It is configured to rotate and to be fully closed at the rotation end to the right side of the operation unit 6.

  The damper device 30 is in a closed state when the operation unit 6 is rotated to the right end in a front view, and when the operation unit 6 is rotated left to the left end, the damper device 30 is illustrated in FIGS. The state of 5 is fully open, that is, a neutral state in which straight air is blown. From this state, when the operation unit 6 is rotated to the right, for example, the rotational force of the operation unit 6 is transmitted to each movable fin 23 of the rotation louver 1 via the first bevel gear mechanism 5, and each movable fin 23 is centered. It rotates so that the angle with respect to the line S1 is gradually inclined, and the air is diffused to be in a state of blowing a mild wind.

  During this time, although the ball shaft member 46 of the rotation transmission mechanism 4 rotates, the end fitting portion 47 of the rotation transmission mechanism 4 idles in the deformed shaft hole 39 of the second bevel gear member 38 so that the second bevel gear member 38 does not rotate. Configured. That is, as shown in FIGS. 20 (a) to 20 (b), when the operation portion 6 is rotated, the movable fin 23 of the rotating louver 2 is first rotated and then further rotated. As shown, the semicircular dampers 31 and 32 rotate in the opposite direction, that is, the direction in which the angle therebetween increases, and rotate until the outer peripheral edge of the semicircular dampers 31 and 32 contacts the wall surface in the retainer 1. The path 15 is closed.

  When assembling the rotating louver 2, first, the operating portion 6 is inserted into the operating portion holding portion 21 b at the front portion of the front cylindrical frame 21, and the shaft portion is inserted into the insertion hole, so that the rear portion of the front cylindrical frame 21 is inserted. The connecting shaft portion 42 of the first bevel gear member 41 is inserted into the shaft portion of the operation portion 6 from the side, and the locking claw is locked to the locking portion. Thereby, the operation part 6 and the 1st bevel gear member 41 are assembled | attached to the center axis line position of the front cylindrical frame 21 so that rotation is reliable.

  Next, the inner support shaft 27 is inserted into the shaft support portion 29 so that the five movable fins 23 are held radially at the position of the shaft support line of the outer peripheral portion of the central shaft support portion 3, and the first bevel gear member 41 is moved. The cylindrical shaft portion 28 of the central shaft support portion 3 is inserted. In this state, the front cylindrical frame 21 and the rear cylindrical frame 22 are supported so that the outer support shaft 24 of the five movable fins 23 is sandwiched and supported by the bearing portion between the front cylindrical frame 21 and the rear cylindrical frame 22. The engaging claw 22a and the engaging portion 21c are engaged with each other.

  In this state, the rotating louver 2 is in a state in which five movable fins 23 are assembled to the cylindrical frame 20, and the first bevel gear piece 25 provided at the base of each movable fin 23 is connected to the first first bevel gear member 41 at the center. Engaged state. The ball shaft member 46 of the ball joint 8 is fitted into the ball joint support portion 11 in the retainer 1 so as to be rotatable about its axis in a state where the ball 44 is positioned forward and horizontally.

  When the rotating louver 2 including the cylindrical frame 20 is mounted in the retainer 1, the stopper 22 b on the outer periphery of the rear cylindrical frame 22 is inserted into the guide groove 1 a in the retainer 1, and the ball 44 is placed at the rear of the central shaft support 3. The ball shaft member 46 of the ball joint 8 is inserted into the ball joint support portion 11 in the retainer 1 in a state where the ball shaft member 46 of the ball joint 8 in the fitted state protrudes rearward.

  Thereafter, as shown in FIG. 18, the second bevel gear member 38, the spring member 38a, and the spring seat 38b are attached to the end fitting portion 47 of the ball shaft member 46 by the attaching screw 38c. At this time, as shown in FIG. 20, the relationship between the fitted end fitting portion 47 and the deformed shaft hole 39 of the second bevel gear 38 is in a state where the rotational force can be transmitted within a predetermined angle range. A damper device 30 assembled with a pair of semicircular dampers 31 and 32 is inserted into the rear side of the retainer 1 or into the ventilation path 15, and upper and lower support shafts 35 b and 33 b of the damper device 30 are arranged at the upper part of the retainer 1. The second bevel gear pieces 36 and 37 of the semicircular dampers 31 and 32 are engaged with the second bevel gear member 38 and assembled. Then, the bezel 9 is fitted into the front portion of the retainer 1 so as to cover the front portion of the rotating louver 2, the locking portion 9a is locked to the locking claw 1b, and the assembly of the register is completed.

  The register having the above-described configuration is used by being mounted on, for example, an air outlet of an air conditioner provided on an instrument panel of an automobile. When changing the blowing direction of the register, the rotation louver 2 is tilted or rotated by holding the operation unit 6. Since the operation unit 6 is formed in a dial shape and is disposed so as to protrude slightly forward from the air outlet 9b, the user can easily hold the operation unit 6 and perform tilting operation or rotation operation.

  As shown in FIGS. 5 and 10, when the damper device 30 is fully opened and the movable fins 23 of the rotating louver 2 are in a state parallel to the center line S <b> 2 along the axial direction of the ventilation path 15, the air flow rotates. It is guided by the movable fins 23 of the louver 2 and blows straight forward, and the spot wind is blown in a relatively narrow area in front.

  When changing the blowing direction of the register, the rotary louver 2 is tilted up and down or left and right by holding the operation unit 6. For example, as shown in FIG. 21, when the operation unit 6 is tilted downward, the rotation louver 2 causes the stopper 22b at the upper end of the cylindrical frame 20 to move forward in the guide groove 1a, and the ball joint 8 The socket member 49 tilts downward about the ball 44. Thereby, as shown in FIG. 21, the rotation louver 2 has its center line S2 inclined downward with respect to the center line S1 of the retainer 1, and the blowing direction is changed obliquely downward. When the operation unit 6 is tilted upward, the rotation louver 2 similarly tilts and the blowing direction is changed obliquely upward.

  In this state, when the operation unit 6 is tilted to the right or left, the rotating louver 2 tilts to the right or left around the axis connecting the stopper 22b and the ball 44 of the ball joint 8, and the blowing direction is changed. It can be changed to the right or left direction diagonally below. Similarly, when the rotating louver 2 is tilted upward or faces straight as shown in FIG. 10, the rotating louver 2 is moved to the right or the center around the axis connecting the stopper 22 b and the ball 44 of the ball joint 8. Tilt to the left, and the air blowing direction is adjusted to the right or left.

  On the other hand, when the air is diffused and blown over a relatively wide range around the front of the air outlet 9b, the control unit 6 is held to the right so that the center line S2 is twisted about the axis.

  At this time, the rotational force of the operation unit 6 is transmitted to the first bevel gear pieces 25 of the five movable fins 23 via the first bevel gear member 41 of the first bevel gear mechanism 5, and the five movable fins 23 are supported by the support shafts. The fin main body of each movable fin 23 is rotated so as to incline back and forth around the radial axis along the transverse section of the ventilation path 15.

  At this time, the relationship between the second bevel gear member 38 of the second bevel gear mechanism 34 and the end fitting portion 47 of the ball shaft member 46 is, for example, 30 ° to the right as shown in FIGS. When rotated within the angular range, the end fitting portion 47 of the ball shaft member 46 idles in the deformed shaft hole 39, and the turning force of the ball shaft member 46 is not transmitted to the second bevel gear member 38. Therefore, while the inclination angle of the movable fin 23 of the rotation louver 2 is changed by the rotation operation of the operation unit 6, the pair of semicircular dampers 31 and 32 of the damper device 30 are in an open state as shown in FIG. Hold.

  As a result, when the air flow passes through the rotation louver 2, the air flow is widened and blown around the center line S2 of the rotation louver 2, and diffused around the air outlet 9b. Diffuse wind <mild wind> is blown. At this time, the air is guided and diffused by the five movable fins 23 disposed inside the air outlet 9b, and a mild wind can be blown.

  On the other hand, in order to block the blowing, the operation unit 6 is further rotated to the right to the rotation end. At this time, the fitting state of the end fitting portion 47 of the second bevel gear member 38 and the ball shaft member 46 is as shown in FIGS. 20 (b) to 20 (c). Hits the contact surface 39 a of the deformed shaft hole 39, and the rotational force of the ball shaft member 46 is transmitted to the second bevel gear member 38.

  As a result, the second bevel gear member 38 of the second bevel gear mechanism 34 rotates, and the pair of semicircular dampers 31 and 32 rotate in the opposite direction, that is, in the closing direction via the second bevel gear pieces 36 and 37. As shown in FIG. 24, the arc-shaped end portions of the semicircular dampers 31 and 32 abut against the inner peripheral surface of the ventilation path 15, and the damper device 30 is closed. At this time, since the periphery of the pair of semicircular dampers 31 and 32 is in contact with the inner peripheral surface of the ventilation path 15, the damper device 30 can prevent wind leakage and be in a fully closed state. At this time, the movable fin 23 of the rotating louver 2 is also rotated in the closing direction, and the inside of the cylindrical frame 20 is substantially fully closed as shown in FIG.

  On the other hand, when the operation portion 6 is turned counterclockwise from such a fully closed state, an operation opposite to the above is performed, while the end fitting portion 47 of the ball shaft member 46 is idle in the deformed shaft hole 39, The rotational force of the operation unit 6 is transmitted to the first bevel gear pieces 25 of the five movable fins 23 via the first bevel gear member 41 of the first bevel gear mechanism 5, and the five movable fins 23 are supported by the support shaft 24, It rotates in the direction opposite to the above about the axis 27. Thereby, the fin main body of each movable fin 23 rotates so that it may face in the direction parallel to centerline S1, S2 of the ventilation path 15, and returns to the original state.

  Further, when the operation portion 6 is turned counterclockwise, the turning force is transmitted from the end fitting portion 47 of the ball shaft member 46 to the second bevel gear member 38, and the pair of semicircular dampers 31 and 32 are On the contrary, the damper device 30 is rotated in the opening direction, the damper device 30 is returned to the fully opened state, and in the blowing state, the angle of the movable fin 23 of the turning louver 2 can be adjusted to blow any diffused air.

  As described above, when the register has the operation portion 6 at the center of the rotation louver 2 and tilts the rotation louver 2 in an arbitrary direction, the rotation louver 2 is supported by the ball joint supported at the center. 8 is tilted about the ball 44, and the blowing direction is changed to an arbitrary direction. When the operation unit 6 is rotated around its axis, the turning force of the operation unit 6 is transmitted to each movable fin 23 via the first bevel gear mechanism 5, and each movable fin 23 has its support shafts 24, 27. For example, when each movable fin 23 becomes substantially parallel to the axial direction of the ventilation path 15, a straight spot wind is blown.

  Further, when the operation unit 6 is rotated around its axis and each movable fin 23 is inclined with respect to the axial direction of the ventilation path 15, for example, the air is diffused by the inclined movable fin 23, and a mild wind is generated. Be blown. Further, when the operation unit 6 is rotated to increase the inclination angle of each movable fin 23 from a predetermined angle, and each movable fin 23 reaches a substantially closed state, a second shaft provided at the end of the ball shaft member 46 of the ball joint 8 is provided. The turning force of the operation unit 6 is transmitted to the pair of semicircular dampers 31 and 32 of the damper device 30 via the two bevel gear mechanism 34, and the semicircular dampers 31 and 32 are rotated to operate the operation unit 6. When the rotation operation is rotated to the rotation end, the ventilation path 15 can be fully closed by the pair of semicircular dampers 31 and 32.

  In this way, it is possible to easily adjust from the spot wind to the mild wind (diffuse wind) only by rotating the operation unit 6 about its axis. At the rotating end of the operation unit 6, the damper device 30. The damper device 30 can tightly close the ventilation path 15 with the semicircular dampers 31 and 32 to prevent wind leakage.
