Description

[Technical Field]

[0001] The technical field of this specification relates to a barrel-type register used in an air outlet for ventilation or air conditioning in an automobile interior, etc., and relates to a register that can improve the ease of attachment of an operating knob. [Background technology]

[0002] Conventionally, a barrel-type register having a rotatable barrel within a retainer has been known as a register for adjusting air blowout in a vehicle cabin. In a barrel-type register, a barrel is rotatably supported inside a retainer, and movable fins are disposed within the barrel. The register is structured so that, by operating an operating knob provided in front of the movable fin, the barrel is rotated, which rotates the movable fin to change the airflow direction, and by rotating the movable fin to its maximum extent, the air passage within the barrel is closed, shutting out the blown air. In this type of register, the barrel and the movable fin are molded independently at the same time within the same mold, and after molding, an operating knob is attached to the front side of one of the movable fins. As a barrel-type register in which an operating knob is attached to a fin, Patent Document 1 below has proposed a register in which a two-part connecting arm portion provided behind the operating knob clamps both sides of the fin, and the rear end of the connecting arm portion is inserted into openings formed on both sides of the fin, and a locking claw provided at the rear end of the connecting arm portion engages with the opening, thereby attaching the operating knob to the fin. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 9-175162 Summary of the Invention [Problem to be solved by the invention]

[0004] However, when shutting out the airflow in this type of register, as shown in Fig. 11(B), the operating knob is operated to rotate the movable fin to its maximum extent, shutting out the ventilation path inside the barrel. At this time, a strong force is applied to the operating knob in the direction opposite to the direction in which the locking claws of the connecting arm are inserted into the opening, i.e., in the direction in which the operating knob is removed from the attached fin. For this reason, conventional registers require the operating knob to be firmly attached to the fin. For example, as shown in Fig. 13, an operating knob 8A is used that includes a connecting arm 83A with a locking claw 84A having a width W4 that is larger than the width W3 of the opening 69A, making it difficult for the operating knob 8A to be removed from the operating fin 52A. In the case of an operating knob 8A having a connecting arm 83A with a locking claw 84A having a width W4 larger than the width W3 of the opening 69A, the opening 69A is difficult to deform when the operating knob 8A is attached to the operating fin 52A, and therefore an excessive pressing force is required to insert the locking claw 84A into the opening 69A, making it difficult to attach by hand. For this reason, conventional registers require the use of a dedicated jig using a cylinder or the like to attach the operating knob 8A, which poses the problem of increased manufacturing costs.

[0005] The problem that the technology of this specification aims to solve has been made in consideration of the above points, and its object is to provide a register that can make it difficult for the operating knob to come off when attached to the fin, and that can improve the ease of attaching the operating knob without using a dedicated jig. [Means for solving the problem]

[0006] The register according to an embodiment of the present specification is a register in which a barrel provided with an air outlet is supported inside a retainer by a barrel support shaft so as to be rotatable up and down, movable fins consisting of multiple fins that can tilt left and right are arranged inside a barrel frame of the barrel, an operation knob for operating the barrel is attached to the front of one of the operation fins of the movable fin, and by operating the operation knob, the barrel is rotated up and down or the movable fin is rotated left and right to change the air direction, and the movable fin is rotated to its maximum extent to shut out the blown air, The back surface of the operation knob is provided with two connecting arms that sandwich the operation fin from the left and right, and the connecting arms are each provided with a locking claw that protrudes outward on the outer left and right sides of the rear end, The operation fin to which the operation knob is attached is provided with an attachment portion, and the attachment portion is provided with fitting holes on both sides of the front side of the operation fin, into which the connecting arm portion is fitted, and the fitting holes are provided with locking plates that protrude rearward and are flexible at the rear side, on the outer left and right sides of the rear side, The connecting arm portion of the operating knob is fitted into the fitting hole of the operating fin, and when the operating knob is attached to the operating fin, the locking claw of the connecting arm portion is locked to the locking plate of the fitting hole.

[0007] Here, the front and rear of the register refer to the downstream side where the conditioned air flows, and the rear side, and the up, down, left, and right refer to the up, down, left, and right sides when the register is viewed from the front. According to the register of the embodiment of this specification, the connecting arm portion of the operation knob is fitted into the fitting hole of the operation fin, and the locking claw at the rear end of the connecting arm portion is engaged with the locking plate protruding rearward from the fitting hole, thereby attaching the operation knob to the operation fin. Because the rear side of the locking plate bends, when the operation knob is attached to the operation fin, the rear side of the locking plate, to which the locking claw of the connecting arm portion is engaged, bends and expands as an opening. Because the rear side of the locking plate expands as an opening and the locking claw is inserted, the operation knob can be attached to the operation fin with relatively little force. Therefore, the register of the embodiment does not require a dedicated jig when attaching the operation knob to the operation fin, and the operation knob can be attached by simply fitting the connecting arm portion together with the locking claw into the fitting hole, improving the ease of attaching the operation knob. Furthermore, when a strong force is applied in a direction that would cause the operation knob to come off the operation fin, the locking claw of the connecting arm portion is locked with the locking plate of the insertion hole, making it difficult for the operation knob to come off.

[0008] In addition, in the above register, the locking plates can each be configured to incline inward in the left-right direction toward the rear, and the side surfaces of the operating fins on the rear side of the insertion hole can each be configured to incline outward in the left-right direction toward the rear.

[0009] This allows the front insertion hole to be made wider on both sides, and the distance between the locking plate and the side of the operating fin narrows toward the rear as an opening, making it easier to insert the connecting arm portion into the insertion hole during installation and making it difficult for the operating knob to come off after installation.

[0010] In the register, the rear end of the locking plate may be formed with a thick portion having a certain thickness and inclining greatly inward.

[0011] With this, the thick portion makes it difficult for the locking plate to crack, and the thick portion is inclined greatly inward, making it difficult for the operating knob to come off.

[0012] In the register, the operation knob may be provided with a reinforcing rib that connects the connecting arm portion and the back surface of the operation knob.

[0013] This suppresses bending of the connecting arm portion relative to the operation knob, making it difficult for the operation knob to come off the operation fin.

[0014] In addition, in the register, the reinforcing rib provided between the two connecting arm portions can be configured to match the shape of the side surfaces on both sides from the tip of the operation fin to which the operation knob is attached.

[0015] According to this, the operation knob attached to the operation fin matches the shape of the operation fin, and rattle can be suppressed. [Effects of the Invention]

[0016] According to the register of the present specification, the operation knob can be attached to the operation fin in a manner that makes it difficult for it to come off, and the ease of attachment of the operation knob can be improved without using a dedicated jig.

DETAILED DESCRIPTION OF THE INVENTION

[0018] A register according to an embodiment of the present specification will be described below with reference to FIGS. 1 to 12. Note that the scope of the present invention is not limited to the scope disclosed in the embodiment. The register according to the embodiment is a barrel-type register. As shown in FIGS. 1 and 2, a barrel 3 having an air outlet 33 is pivotally supported in the front portion of a duct-shaped retainer 2 by barrel support shafts 34 protruding from both sides of the barrel 3 so as to be vertically rotatable. Four vertical fins 51 that can tilt left and right are arranged side by side in the left-right direction inside a barrel frame 31 of the barrel 3 as movable fins 5 that can adjust the airflow direction left and right. An operation knob 8 for operating the barrel 3 is attached to the front of an operation fin 52, which is one of the fins 51 inside the movable fins 5. By operating the operation knob 8, the register can rotate the barrel 3 up and down or rotate the movable fin 5 left and right to adjust the airflow direction, and can rotate the movable fin 5 to the maximum right to close the ventilation passage 32 and shut out the airflow.

[0019] In this specification, the orientation of the register is defined as the front, as shown in Figures 1(B) and 2, with the side of the register having the air outlet 33 of the barrel 3, and the rear, as shown in Figures 1(B) and 2, with the side of the register having the air inlet 22 in the retainer 2. Up, down, left, and right refer to the up, down, left, and right directions when viewing the register from the front, and as used in the drawings, F indicates the front, B indicates the rear, U indicates the top, D indicates the bottom, L indicates the left, and R indicates the right. Also, based on the regulated air flow, the front may be expressed as the downstream side, and the rear as the upstream side. Furthermore, the terms "inside" and "outside" may be used with respect to the ventilation passage 21 in the retainer 2, the ventilation passage 32 in the barrel 3, and the insertion hole 61 in the mounting portion 6.

[0020] As shown in FIGS. 2 and 11 , the barrel 3 is rotatably (vertically tiltably) supported in the front portion of the retainer 2 via barrel shafts 34 provided at both the left and right ends of the barrel 3. To rotatably support the barrel shaft 34 of the barrel 3, a bearing 23 that directly supports the left barrel shaft 34 is provided on the left sidewall of the front portion of the retainer 2, and a bearing support 24 that supports the right barrel shaft 34 via a bearing member 25 is provided on the right sidewall. The bearing member 25 is made of a rubber elastic material or the like and is fitted into the bearing support 24. The bearing member 25 applies an appropriate operating load to the operator when rotating the barrel 3 and, by frictional resistance, prevents malfunction due to vibrations while the vehicle is traveling. As shown in FIGS. 1 and 2 , a bezel 1 that forms a decorative surface is fitted to the front surface of the retainer 2. The bezel 1 is formed in a tapered shape so as to enclose the front edge of the barrel 3, and the air outlet 33 on the front surface of the barrel 3 is exposed to the front from the front opening of the bezel 1 to form an air outlet.

[0021] 1 and 2, the barrel frame 31 forming the outer shell of the barrel 3 is formed in the shape of a horizontally long rectangular frame when viewed from the front, and inside the barrel frame 31, a left-right blade 4 is fixed to the front, and a movable fin 5 consisting of four vertical fins 51 arranged on the left and right that can tilt left and right is arranged to the rear, and an operation knob 8 for operating the barrel 3 is attached to the front of one operation fin 52 on the center side of the fin 51. The blades 4 are installed respectively above and below the operation knob 8, and the left and right ends of the blades 4 are connected and fixed to the barrel 3 by plate-shaped decorative parts 41 that extend in the up-down and front-to-rear directions.

[0022] As shown in FIGS. 1, 2, and 11, the movable fins 5 are configured by four fins 51 arranged side by side on the rear side of the barrel frame 31, each extending in the vertical direction perpendicular to the axial direction of the barrel support shaft 34. As shown in FIG. 2, each fin 51 is pivotally supported so as to be rotatable in the horizontal direction by having the upper support shaft 53 of each fin 51 fitted into the shaft hole 36 provided in the upper part of the barrel frame 31 and the lower support shaft 53 fitted into the shaft hole 36 provided in the lower bearing part 35 connected to the lower rear side of the barrel frame 31. Each fin 51 is connected to a connecting shaft 54 protruding from one end of each fin 51, away from the shaft hole 36, by a single link bar 55 shown in FIG. 2, so that all fins 51 can synchronously change their orientation left and right. An operating fin 52 of the center fin 51 is provided with an attachment part 6, and an operating knob 8 is attached to the attachment part 6.

[0023] The barrel 3 and movable fins 5 of this embodiment are molded by injection molding of synthetic resin, and the barrel 3 (barrel frame 31), movable fins 5 (fins 51), and link bar 55 are molded simultaneously in the mold during molding, and are automatically assembled in the mold during molding. A separate lower bearing portion 35 (FIG. 2) is assembled to the lower rear side of the barrel frame 31 of the barrel 3. Due to the structure of the mold used during molding, the operation knob 8 cannot be molded integrally with the operation fins 52 of the fins 51, and instead, the operation knob 8 is attached to the operation fins 52 after the barrel 3 and movable fins 5 are molded and assembled.

[0024] 11(B), when shutting out the airflow, the register of this embodiment rotates the movable fin 5 to the right as far as possible by operating the operation knob 8, shutting out the ventilation passage 32 inside the barrel 3. At this time, a strong force is applied to the operation knob 8 in a direction that causes the operation knob 8 to come off the attached operation fin 52. For this reason, the operation knob 8 needs to be attached to the operation fin 52 firmly and easily.

[0025] As shown in Fig. 3, the operation knob 8 attached to the operation fin 52 has a roughly semicircular shape with an extension 82 at the rear of the left end, which extends the circumference, and when shutting out the air, as shown in Fig. 11(B), even if it is turned all the way to the right, the extension 82 remains at the front of the register, making it easy to turn. In addition, the side of the operation knob 8 on the circumferential side is knurled to create an uneven surface, which improves the grip of the operating finger and makes it easy to turn the operation knob 8.

[0026] 3 and 5 to 7, the operation knob 8 is provided on its rear back surface 8a with two connecting arms 83 that hold the left and right side surfaces of the operation fin 52, and a protruding locking claw 84 is provided on one of the outer left and right sides of the rear end of the connecting arms 83. When the operation knob 8 is attached to the operation fin 52, the locking claw 84 is locked to the rear end of a locking plate 62 of the attachment portion 6 of the operation fin 52, which will be described later, and firmly attaches the operation knob 8 to the operation fin 52.

[0027] As shown in FIGS. 5 and 7A, the operation knob 8 is provided with reinforcing ribs 83a on the left side of the connecting arm portion 83, between the connecting arm portions 83, and on the right side of the connecting arm portion 83 so as to connect the connecting arm portion 83 to the back surface 8a of the operation knob 8. The reinforcing ribs 83a improve the strength of the connecting arm portion 83 and suppress bending of the connecting arm portion 83, thereby preventing the operation knob 8 attached to the operation fin 52 from falling off. The reinforcing ribs 83a attached between the connecting arms 83 are formed in a substantially U-shape so as to match the shape of the tip 52a and both side surfaces 52b of the operation fin 52 to which the operation knob 8 is attached. This allows the operation knob 8 attached to the operation fin 52 to match the shape of the operation fin 52, suppressing rattle after attachment. The rear end of the reinforcing rib 83a between the connecting arms 83 is provided with a chamfered portion 83b inclined outward, which improves the ease of attachment when the operation knob 8 is attached to the operation fin 52.

[0028] 3 and 4, the operation fin 52 to which the operation knob 8 is attached is provided with a mounting portion 6 to which the operation knob 8 is attached, at approximately the center in the up-down direction on the front side. The mounting portion 6 is provided with an insertion hole 61 into which the connecting arm portion 83 of the operation knob 8 is inserted, locking plates 62 that protrude rearward and are flexible at the rear side, on each of the outer left and right sides of the rear side of the insertion hole 61, and clamping plates 63, on the top and bottom of the insertion hole 61, that clamp the inserted connecting arm portion 83 from above and below.

[0029] The insertion hole 61 is a generally rectangular hole that is longer in the left-right direction than in the up-down direction, and is divided into left and right halves by the tip 52a of the operation fin 52. The left and right sides of the connecting arm portion 83 of the operation knob 8 are inserted into the insertion hole 61, respectively.

[0030] The locking plates 62 are provided on the outer left and right sides of the rear side of the insertion hole 61, protruding rearward so that their protruding rear sides can bend left and right. When the connecting arm portion 83 of the operation knob 8 is inserted into the insertion hole 61, the locking claws 84 protruding outward in the left and right direction from the rear end of the connecting arm portion 83 are locked onto the rear end of the locking plates 62, and the operation knob 8 is attached to the operation fin 52.

[0031] As shown in FIG. 7(A), each of the locking plates 62 is inclined inward in the left-right direction toward the rear (angle α1 of 5°), and has a thick portion 62a and an inclined surface 62b at its rear end that is inclined significantly inward (angle α2 of 30°). As shown in FIG. 7(A), the operation fin 52 inside the mounting portion 6 has a tip 52a that forms a semi-cylindrical surface, and each of the side surfaces 52b is inclined outward in the left-right direction toward the rear (angle α3 of 5°). This allows the width W1 of the front insertion hole 61 to be wider than the width W2 on the locking claw 84 side, making it easier to insert the connecting arm portion 83 into the insertion hole 61 when attaching the operation knob 8. Furthermore, because the distance between the locking plate 62 and the side surface 52b of the operation fin 52 narrows toward the rear, the operation knob 8 is less likely to come off after attachment.

[0032] 3 and 4, clamping plates 63 are provided above and below the insertion hole 61, and clamp the connecting arm portion 83 of the operation knob 8 inserted into the insertion hole 61 from above and below. Receiving surfaces 85 that protrude from the connecting arm portion 83 are formed above and below the connecting arm portion 83 of the operation knob 8, as shown in Fig. 5. As a result, when the connecting arm portion 83 of the operation knob 8 is inserted into the insertion hole 61, the clamping plates 63 clamp and fix the receiving surfaces 85 that protrude from the connecting arm portion 83, and the vertical position of the connecting arm portion 83 with respect to the insertion hole 61 is determined, as shown in Fig. 8.

[0033] As shown in FIG. 3 , the left sides of the upper and lower clamping plates 63 are connected across the front and rear by a side wall 64 extending in the vertical and longitudinal directions, thereby increasing the rigidity of the clamping plates 63 and, ultimately, the mounting portion 6. The left locking plate 62 protrudes rearward from the rear end of the side wall 64. The right sides of the upper and lower clamping plates 63 are connected at their rear ends by a flange 65 extending in the vertical and lateral directions, and the right locking plate 62 protrudes rearward from the left end of the flange 65. As shown in FIG. 5 , the reinforcing rib 83a on the right side of the connecting arm portion 83 on the back surface 8a of the operation knob 8 extends rearward and is provided with an abutment portion 86 that abuts against the flange 65 of the mounting portion 6. When the operation knob 8 is attached to the operation fin 52, the abutment portion 86 of the operation knob 8 abuts against the flange 65 of the operation fin 52, thereby suppressing rattling of the operation knob 8. Furthermore, when the movable fin 5 is rotated to the maximum extent to the right to shut out the ventilation passage 32, the excessive pressing force that is generated is reversed using the operating fin 52 as a lever, as shown in Figure 11 (B), and the pressing force is received by the flange 65 of the operating fin 52 from the abutment portion 86 of the operating knob 8, thereby distributing the load on the mounting portion 6.

[0034] As shown in FIGS. 3 and 4A, the right side of the lower clamping plate 63 is shorter in the left-right direction than the upper clamping plate 63, and a missing portion 63a is formed. Also, as shown in FIG. 5, a protruding portion 87 that protrudes downward is formed below the abutting portion 86 of the operation knob 8. The operation knob 8 is configured so that, when the connecting arm portion 83 of the operation knob 8 is fitted into the fitting hole 61 of the mounting portion 6 of the operation fin 52 in the correct orientation, the protruding portion 87 can enter the missing portion 63a, as shown in FIGS. 9 and 12A, and the operation knob 8 can be attached to the operation fin 52. On the other hand, when the connecting arm portion 83 of the operation knob 8 is fitted into the fitting hole 61 of the mounting portion 6 of the operation fin 52 in the upside-down (left-right) orientation, the protruding portion 87 (abutting portion 86) interferes with the left side wall 64 of the clamping plate 63, as shown in FIG. 12B, and the operation knob 8 cannot be attached to the operation fin 52. That is, it is possible to prevent the operation knob 8 from being attached in the wrong direction (upper or lower direction).

[0035] Next, the assembly of the register of the embodiment will be described. The register of the embodiment is roughly composed of a bezel 1, a retainer 2, and a barrel 3, as shown in FIG.

[0036] The barrel 3 is formed by injection molding the barrel frame 31 and movable fins 5 (fins 51) of synthetic resin. The barrel frame 31, fins 51, and link bar 55 are molded simultaneously and automatically assembled in the mold during molding. A lower bearing 35 (Fig. 2) is assembled to the barrel frame 31 from the lower rear side. After molding and assembling the barrel 3, the operation knob 8 is attached to the operation fins 52 of the movable fins 5.

[0037] 3, when the operation knob 8 is attached to the operation fin 52, the two connecting arms 83 of the operation knob 8 are fitted rearward through the fitting holes 61 of the attachment portion 6 of the operation fin 52. At this time, as shown in FIG. 7(A), the width W1 of the fitting holes 61 is set wider than the width W2 of the locking claws 84 of the connecting arms 83, so that the connecting arms 83 can be easily fitted into the fitting holes 61.

[0038] As shown in FIG. 7(A), each of the locking plates 62 is inclined inward in the left-right direction toward the rear, and each of the side surfaces 52b of the operation fin 52 inside the mounting portion 6 is inclined outward in the left-right direction toward the rear, with the distance between the locking plate 62 and the side surface 52b of the operation fin 52 narrowing toward the rear. When the connecting arm portion 83 is inserted into the rear of the insertion hole 61, the rear of the locking plate 62 is bent, so that the rear side of the locking plate 62, which engages the locking claw 84 of the connecting arm portion 83, is bent outward and widened to form an opening. Because the rear side of the locking plate 62 is widened to form an opening through which the locking claw 84 can be inserted, the operation knob 8 can be attached to the operation fin 52 with a relatively small force. Furthermore, because the distance between the locking plate 62 and the side surface 52b of the operation fin 52 narrows toward the rear, the operation knob 8 is less likely to come off after attachment.

[0039] When the connecting arm portion 83 of the operation knob 8 is inserted rearward through the insertion hole 61 of the mounting portion 6 and the locking claw 84 at the rear end of the connecting arm portion 83 passes the rear end of the locking plate 62 of the mounting portion 6, as shown in the enlarged view of Figure 10, the rear end of the locking plate 62, which has bent outward, enters the inside of the locking claw 84, and the locking claw 84 is locked to the locking plate 62, and the operation knob 8 is attached to the operation fin 52.

[0040] When the connecting arm portion 83 of the operating knob 8 is fitted into the fitting hole 61 of the operating fin 52 and the operating knob 8 is attached to the operating fin 52, the rear side of the locking plate 62 of the fitting hole 61 bends, so that the connecting arm portion 83 together with the locking claw 84 can be fitted into the fitting hole 61 with a relatively weak force, and the operating knob 8 can be attached to the operating fin 52 without using a dedicated jig, thereby improving the attachability of the operating knob 8.

[0041] When the operation knob 8 is attached to the operation fin 52, the two connecting arms 83 sandwich the operation fin 52 from the left and right. In addition, a reinforcing rib 83a provided between the connecting arms 83 matches the shape of the tip 52a of the operation fin 52 and the side surfaces 52b on both sides, and a receiving surface 85 protruding from the connecting arms 83 is sandwiched between the clamping plates 63, and the abutting portion 86 of the operation knob 8 abuts against the flange 65 of the operation fin 52, thereby suppressing rattle after attachment. When a strong force is applied in a direction that would remove the operation knob 8 from the operation fin 52, the locking claw 84 of the connecting arm 83 is locked with the locking plate 62, making it difficult for the operation knob 8 to come off.

[0042] 2, the register fits the barrel 3 by fitting the barrel support shafts 34 at both left and right ends of the barrel 3 into the bearing support parts 24 via the bearing parts 23 and bearing members 25 in the retainer 2 from the downstream side inside the retainer 2. The bezel 1 is fitted to the front part of the retainer 2.

[0043] The operator can adjust the wind direction in the vertical direction of the barrel 3 by operating the operation knob 8 up and down, and can adjust the wind direction in the horizontal direction of the movable fin 5 by rotating the operation knob 8 left and right. In other words, the operation knob 8 can adjust the wind direction in the horizontal and vertical directions.

[0044] A register equipped with the barrel 3 configured as described above is mounted on the instrument panel or dashboard inside an automobile, with the air intake port 22 at the rear end of the retainer 2 connected to a ventilation duct (not shown). Air sent from the ventilation duct flows from the ventilation passage 21 inside the retainer 2 to the ventilation passage 32 of the barrel 3 and is blown out through the air outlet 33.

[0045] When adjusting the air blowing direction up or down, turning the operation knob 8 up or down rotates the barrel 3 up or down about the barrel support shaft 34, changing its orientation up or down, and the register adjusts the air blowing direction up or down. When adjusting the air blowing direction left or right, turning the operation knob 8 left or right rotates the operation fin 52, to which the connecting arm 83 at the rear of the operation knob 8 is attached, left or right, as shown in Fig. 11, and rotates the movable fin 5 left or right via the link bar 55 (Fig. 2), changing its left or right orientation within a predetermined angle range, and the register adjusts the air blowing direction left or right.

[0046] To stop the airflow, the operating knob 8 is rotated to the right as far as possible, as shown in Fig. 11(B). This rotates the fins 51 of the movable fin 5 to the right, and the fins 51 overlap with the fins 51 arranged side by side on the left and right. When the fins 51 overlap each other, the movable fin 5 closes the ventilation passage 32, and the register stops airflow.

[0047] The register according to the embodiment of the present specification is a register in which a barrel 3 provided with an air outlet 33 is supported inside a retainer 2 by a barrel support shaft 34 so as to be rotatable up and down, a movable fin 5 consisting of a plurality of fins 51 that can tilt left and right is arranged inside a barrel frame 31 of the barrel 3, an operation knob 8 for operating the barrel 3 is attached to the front of one operation fin 52 of the movable fin 5, and by operating the operation knob 8, the barrel 3 is rotated up and down or the movable fin 5 is rotated left and right to change the air direction, and the movable fin 5 is rotated to its maximum extent to shut out the blown air, The rear surface 8a of the operation knob 8 is provided with two connecting arms 83 that sandwich the operation fin 52 from the left and right, and the connecting arms 83 are each provided with a locking claw 84 that protrudes outward on the outer lateral sides of the rear end in the left-right direction, The operation fin 52 to which the operation knob 8 is attached is provided with an attachment portion 6, and the attachment portion 6 is provided with fitting holes 61, into which the connecting arm portion 83 is fitted, on both sides of the front side surface 52b of the operation fin 52, and the fitting holes 61 are provided with rearward-protruding locking plates 62, the rear sides of which are flexible, on the outer left and right sides of the rear side, The connecting arm portion 83 of the operating knob 8 is fitted into the fitting hole 61 of the operating fin 52, and when the operating knob 8 is attached to the operating fin 52, the locking claw 84 of the connecting arm portion 83 is locked into the locking plate 62 of the fitting hole 61.

[0048] According to the register of the embodiment of the present specification, the connecting arm portion 83 of the operation knob 8 is fitted into the fitting hole 61 of the operation fin 52, and the locking claw 84 at the rear end of the connecting arm portion 83 is locked with the locking plate 62 protruding rearward from the fitting hole 61, thereby attaching the operation knob 8 to the operation fin 52. Because the rear of the locking plate 62 bends, when the operation knob 8 is attached to the operation fin 52, the rear side of the locking plate 62, to which the locking claw 84 of the connecting arm portion 83 is locked, is bent and expanded as an opening. Because the rear side of the locking plate 62 is expanded as an opening and the locking claw 84 is inserted, the operation knob 8 can be attached to the operation fin 52 with a relatively weak force. Therefore, with the register of the embodiment, there is no need to use a dedicated jig when attaching the operation knob 8 to the operation fin 52. The operation knob 8 can be attached by fitting the connecting arm portion 83 together with the locking claw 84 into the fitting hole 61, improving the attachability of the operation knob 8. Furthermore, when a strong force is applied in the direction of removing the operating knob 8 from the operating fin 52, the locking claw 84 of the connecting arm portion 83 is locked into the locking plate 62 of the insertion hole 61, making it difficult to remove.
