  As shown in FIGS. 11 and 12, in the ball shaft member 11, the disk portion 120, the shaft member 115, the ball portion 110, and the engagement pin 112 are integrally formed. For this reason, compared with the case where each component is separately shape | molded and assembled, the variation in the dimension of each component for every product is reduced, and the rattling by the dimensional error for every product can be suppressed. In addition, the manufacturing cost can be reduced by reducing the number of molding processes and the number of assembling steps.

  At the front end of the shaft portion 115 of the ball shaft member 11, a disc portion 120 is provided, as shown in FIGS. As shown in FIG. 19A, an annular knob bearing 130 is provided at the rear of the knob support 5 of the barrel 3. The disk portion 120 is rotatably supported by the knob bearing portion 130, and as shown in FIG. 6, the operation knob 6 is mounted on the knob shaft supporting portion 5 at the front of the knob bearing portion 130 of the barrel 3.

Thereby, the register of the embodiment can suppress the gap and the rattling due to the dimensional tolerance of each part, and can improve the operation feeling at the time of the opening and closing operation of the damper device 20. In addition, since the register of the embodiment generates a feeling of moderation without using another component, the moderation feeling imparting unit 101 can be configured with a small number of parts, and the manufacturing cost can be suppressed. ing.

  The ball joint portion 8 is composed of a ball shaft member 11 provided with a ball portion 110 at its tip and a socket member 12 externally fitted to the ball portion 110.

  As shown in FIG. 6, the ball portion 110 of the ball shaft member 11 is fitted on the socket member 12 to form the ball joint portion 8 shown in FIG. At this time, the engagement pin 112 (FIG. 12) of the ball portion 110 engages with the engagement groove 12a (FIG. 13 (b)) of the socket member 12, and the rotation (from the ball shaft member 11) from the operation knob 6 Motion is transmitted to the socket member 12.

  A recessed portion 111 is provided on the outer periphery of the ball portion 110 as shown in FIGS. By providing the recessed portion 111 on the outer periphery of the ball portion 110, the contact area with the socket member 12 can be reduced, and the register can be adjusted in operation load. Further, on the outer periphery of the ball portion 110, an engagement pin 112 is provided which protrudes in the outer peripheral direction of the ball shaft member 11 and engages with the engagement groove 12a (FIG. 13B) of the socket member 12. There is. The rotation of the operation knob 6 is transmitted to the socket member 12 by the engagement pin 112 engaging with the engagement groove 12 a. It is preferable to use a hard material for the shaft member 11 in which the stress associated with the turning operation of the operation knob 6 is concentrated, and metal, hard plastic or the like can be used as the hard material. For the shaft member 11 of the embodiment, glass fiber filled polybutylene phthalate (PBT-G 30%) which is hard plastic was used.

  As shown in FIG. 13, the socket member 12 is composed of two members in the left-right (up-down) symmetrical shape so that the ball portion 110 can be fitted externally, and interlocked with the rotation from the operation knob 6 (from the ball portion 110) Thus, the engagement groove 12a with which the engagement pin 112 of the ball portion 110 engages is provided. As shown in FIG. 10, the socket member 12 is a member which is externally fitted with the ball portion 110, is tiltable for tilting operation of the barrel, and applies an operation load, and is made of synthetic resin elastomer or the like. It is formed. As a result, when the ball shaft member 11 tilts up, down, left, and right in accordance with the tilting operation of the barrel 3 in the up, down, left, and right directions, the ball shaft member 11 tilts smoothly without causing grimaciness or rattle.

  The socket support member 13 externally fits the socket member 12 (ball joint portion 8) fitted with the ball portion 110 of the ball shaft member 11 from the rear as shown in FIG. 14, and as shown in FIG. It is a member supported by the central support 2 of 1. While strongly protecting the socket member 12 formed of a synthetic resin elastomer or the like, the ball portion 110 is prevented from being easily detached from the socket member 12. A gear attachment shaft 14 provided at the rear end of the socket support member 13 is a member for transmitting the rotation of the socket support member 13 to a bevel gear 15 described later, and as shown in FIG. A bevel gear 15 is fitted to the gear mounting shaft 14 from the rear with the two interposed therebetween. On the outer peripheral side of the socket member 12, as shown in FIG. 13, a locking claw 12b for suppressing the rotation with the socket support member 13 is protruded, and on the inner peripheral circle side of the socket support member 13, FIG. As shown in FIG. 2, a claw receiving groove 13b is provided whose rotation is restrained by the locking claw 12b. Thereby, the rotation of the ball joint portion 8 (operation knob 6) is transmitted from the gear mounting shaft 14 to the bevel gear 15 via the rotation transmission mechanism 10. Further, as shown in FIG. 9, the locking claw 12 c (FIG. 13) of the socket member 12 is held by the locking claw receiver 13 c (FIG. 14) of the socket support member 13 to hold the ball portion 110. The upper and lower divided socket members 12 (FIG. 13B) are fitted into the socket support members 13. Thus, the socket member 12 can be protected in a strong manner, and the ball portion 110 can be prevented from easily coming off the socket member 12.

  As shown in FIG. 18, when the rotation transmission mechanism 10 is assembled to the central shaft support 2 of the retainer 1, the gear mounting shaft 14 at the rear of the socket support member 13 penetrates the central shaft support 2 of the retainer 1 and The bell gear 15 is fitted. At this time, the gear mounting shaft 14 has an irregular cross section, and a space is formed in the internal axial direction, so that the bevel gear 15 can be easily inserted into and attached to the gear mounting shaft 14 during assembly. It has become.

  The damper device 20 is composed of two semicircular dampers 21 and 22 as shown in FIGS. 6 and 7, and as shown in FIG. The air passage 1a of the retainer 1 is axially supported by the damper bearing 1c (FIGS. 3, 17 and 18) so as to be able to open and close. As shown in FIGS. 21 and 23, the two semicircular dampers 21 and 22 open or close the air passage 1a by tilting them opposite to each other in the vertical direction. As shown in FIGS. 6 and 7, beveled gear pieces 25 and 26 are respectively provided on the strings of the two semicircular dampers 21 and 22, and rotation is transmitted from the operation knob 6 through the rotation transmission mechanism 10. By meshing with the bevel gear 15 to be rotated, the rotation of the operation knob 6 tilts the two semicircular dampers 21 and 22 oppositely in the vertical direction, and the air passage 1a can be opened or closed.

  The register of the above configuration is assembled as follows. As shown in FIG. 6, the rotation transmission mechanism 10, the damper device 20, the barrel 3, the operation knob 6 and the bezel 7 are assembled in order to the retainer 1.

  The rotation transmission mechanism 10 is assembled by first assembling the ball joint 8 and assembling the socket support member 13 and the bevel gear 15 to the ball joint 8.

  As shown in FIG. 10, the ball joint portion 8 engages the engagement pin 112 of the ball portion 110 of the ball shaft member 11 with the locking claw 12b of the socket member 12 as shown in FIG. 13 (b). The upper and lower two divided socket members 12 are assembled so as to be held by the upper and lower halves 110. Next, the socket support member 13 is fitted to the ball joint portion 8. At this time, the locking claw 12b of the socket member 12 shown in FIGS. 13 and 14 is engaged with the claw receiving groove 13b of the socket support member 13, and the locking claw 12c of the socket member 12 is locked in the locking claw of the socket support member 13. The socket support member 13 is fitted to the ball joint portion 8 by being locked to the receiver 13c (FIG. 9).

  The gear mounting shaft 14 of the socket member 12 fitted to the ball joint portion 8 is inserted into the central shaft support portion 2 of the retainer 1 so as to turn from the front side, and as shown in FIGS. The bevel gear 15 is attached to the gear attachment shaft 14 from the rear with the (retainer 1) interposed therebetween, and the rotation transmission mechanism 10 is assembled. At this time, since the gear mounting shaft 14 has a deformed cross section and a space is formed in the internal axial direction, the bevel gear 15 can be easily fitted into and attached to the gear mounting shaft 14.

  As shown in FIG. 24, the damper device 20 connects the convex portion of the shaft portion 23 of the semicircular dampers 21, 22 and the concave portion of the shaft portion 24 in a hinge shape, and as shown in FIG. And the shaft portions 23, 24 are rotatably mounted on the damper bearing 1c. At this time, the bevel gear 15 at the rear of the rotation transmission mechanism 10 and the bevel gear pieces 25 and 26 provided on the strings of the semicircular dampers 21 and 22 mesh with each other.

  The barrel 3 engages the engagement shaft 3b (FIG. 19) with the engagement groove 1b (FIG. 16), and the knob bearing portion 130 (FIG. 19 (a)) has the disc portion 120 (FIG. 16) of the ball shaft member 11. To be held, as shown in FIG. At this time, the projection 122 of the elastic bending portion 121 provided on the outer peripheral portion of the disk portion 120 abuts on the inner peripheral surface of the knob bearing portion 130 as shown in FIG. As a result, when the ball shaft member 11 rotates, the protrusion 122 gets over the protrusion 131 of the knob bearing portion 130, and a click can be generated. On the front side of the retainer 1 to which the barrel 3 is attached, a bezel 7 for decorating the register is attached to prevent the barrel 3 from being detached.

  The operation knob 6 is pivotably attached to the knob shaft supporting portion 5 on the front surface of the barrel 3 from the front of the barrel together with the operation applying member 19. At this time, the locking claw 6a of the operation knob 6 penetrates the guide groove 5a of the barrel 3 and is locked to the operation knob claw holder 123 (FIG. 20 (c)) of the ball shaft member 11 and rotates with the operation knob 6 As the transmission mechanism 10 is integrated, the register is assembled.

  Next, the operation accompanying the operation of the register will be described. The register opens and closes the air blower by opening and closing the damper device 20 by the turning operation of the operation knob 6 and adjusts the wind direction by the tilting of the barrel 3.

  When closing the damper, the operation knob 6 is turned clockwise as shown in FIG. 23, and the damper device 20 closes the air passage 1a. When the damper is opened, as shown in FIG. 21, the operation knob 6 is turned counterclockwise, and the damper device 20 opens the air passage 1a. At this time, the rotational force of the operation knob 6 is transmitted from the ball portion 110 of the ball shaft member 11 to the engagement groove 12 of the socket member 12 via the engagement pin 112, and the rotational force of the operation knob 6 is the ball portion 110. Through the engagement pin 112, the socket member 12, and the socket support 13, to the bevel gear 15 on the rear side. When the bevel gear 15 rotates, the bevel gear pieces 25 and 26 meshing therewith rotate the semicircular dampers 21 and 22 relative to each other in the vertical direction, and the air passage 1a is opened or closed.

  As shown in FIG. 20C, when the operation knob 6 is rotated, the elastic bending portion 121 of the outer peripheral portion of the disk portion 120 is elastically deformed, and the protrusion 122 is a protrusion 131 of the knob bearing 130. By passing over (Figs. 19 (a) and 20 (c)), the user feels moderated when the damper device 20 is closed or opened, and the user is in the closed or opened state. It can be confirmed. As described above, since the elastic bending portion 121 and the projection portion 122 are integrally molded with the disk portion 120 (ball shaft member 11) and the convex portion 131 is integrally molded with the knob bearing portion 130 (barrel 3) The part 101 generates a click feeling (moderation feeling) of the operation knob 6 without interposing another part such as a biasing member. As a result, the number of parts can be reduced, the manufacturing cost can be suppressed, and the gap and rattling due to the dimensional tolerance of each part for each product can be suppressed, and the operation feeling when opening and closing the damper device 20 can be improved. Further, the operation knob 6 is pivotally supported by the knob shaft supporting portion 5 via the operation load applying member 19 made of an elastic elastomer, and an appropriate operation load is applied to the operation knob 6, so The operating vibration does not cause the operation knob 6 to rotate naturally, and the traveling vibration does not change the air volume from the register.

  When changing the blowing direction up and down or left and right, the barrel 3 is tilted up and down or left and right by holding the operation knob 6. When changing the blowing direction up or down, the barrel 3 is tilted up or down. The barrel 3 can be tilted back and forth (up and down) by the engagement groove 3b (FIG. 19) by the engagement groove 1b (FIG. 16). Therefore, as shown in FIGS. The barrel 3 tilts up or down, and the air flow is adjusted up and down. When the air blowing direction is changed to the left or right, as shown in FIGS. 24 and 25, the barrel 3 is tilted to the left or right. The barrel 3 can be tilted to the left or right about the line connecting the ball 110 and the engagement shaft 3b, since the barrel 3 can be tilted to the left or right about the line connecting the ball 110 and the engagement shaft 3b. Will be adjusted.

  When the barrel 3 is tilted, the ball portion 110 is rotated relative to the socket member 12 of the ball joint portion 8. However, since the socket member 12 is formed of a load applying member made of an elastic elastomer, An appropriate load is applied, and the traveling vibration of the attached automobile does not change the angle of the barrel 3 and the air blowing direction does not change naturally. And, since the socket member 12 is an elastic elastomer, the barrel 3 tilts smoothly without feeling of stiffness.

  Thus, according to the above-mentioned register, when the user operates the operation knob 6 to open and close the damper device 20, the moderation feeling imparting unit 101 acts to generate a moderation feeling (click feeling), When the register is in the damper closed state (damper open state), the user can recognize it by the sense of moderation. Conventionally, in order to generate the click feeling of the operation knob, another component such as the biasing member is provided at the rotation boundary portion, but in the above register, the click feeling of the operation knob 6 without interposing another component As a result, it is possible to suppress a gap or rattling due to dimensional tolerance of each part, and to improve the operation feeling at the time of opening and closing operation of the damper device 20. Moreover, since the register | resistor of this invention can be comprised with a small number of parts, manufacturing cost can be held down.
