Further, a receiving hole portion 38 is formed in the extending portion 37, and the sliding member 28 is inserted into each of the receiving hole portions 38 and held so as to advance and retreat. The receiving holes 38 are formed at both ends of the extending portion 37 in the longitudinal direction. Further, a stopper portion 28 a formed on the sliding member 28 can come into contact with the extending portion 37 . The stopper portion 28 a is located inside the extension portion 37 . The movement range of the sliding member 28 is restricted by the contact between the stopper portion 28a and the extension portion 37. As shown in FIG.

このように、押し付け部材２６、受け部材２７、及び、摺動部材２８は、それぞれ本体部１３と被取付部７との間に収納されている。 In this manner, the pressing member 26, the receiving member 27, and the sliding member 28 are housed between the body portion 13 and the attached portion 7, respectively.

延出部３７は、取付穴部１０に内挿され、外面が取付穴部１０の内面と対向している。この延出部３７の外方に、取付穴部１０の内縁部に係止される係止部４０が形成されている。係止部４０の先端部に、爪形状が外側に向けて突出して形成されており、この爪形状が取付穴部１０の内縁部に係合されることで、回動体５が被取付部７に対し抜け止め保持されている。 The extending portion 37 is inserted into the mounting hole portion 10 and has an outer surface facing the inner surface of the mounting hole portion 10 . A locking portion 40 that is locked to the inner edge portion of the mounting hole portion 10 is formed outside the extension portion 37 . A claw shape is formed on the distal end portion of the engaging portion 40 so as to protrude outward. It is held against falling out.

係止部４０は、回動体５すなわち本体部１３の周方向において、延出部３７の受け穴部３８，３８と交差または直交する位置にある。本実施の形態において、係止部４０は、延出部３７の短手方向の両端部の外方に位置する。係止部４０は、本体部１３の対向面１４から被取付部７側に舌片状に突出する。係止部４０の外面と延出部３７の長手方向の外面とは、回動軸線を中心軸とする同一円筒面上に位置する。 The locking portion 40 is located at a position that intersects or is orthogonal to the receiving holes 38 , 38 of the extension portion 37 in the circumferential direction of the rotating body 5 , that is, the main body portion 13 . In the present embodiment, the locking portions 40 are positioned outside both ends of the extending portion 37 in the lateral direction. The engaging portion 40 protrudes from the facing surface 14 of the main body portion 13 toward the attached portion 7 in a tongue shape. The outer surface of the engaging portion 40 and the longitudinal outer surface of the extending portion 37 are positioned on the same cylindrical surface with the rotation axis as the central axis.

好ましくは、トルク設定部２４は、受け部材２７の位置を調整する調整部材４２を有する。調整部材４２は、本体部１３の配置部３３に対し、動作可能に配置される。本実施の形態において、調整部材４２は、ボルトであり、受け部材２７に螺着されて、その回動に応じて受け部材２７の位置を進退方向に微調整可能となっている。調整部材４２は、壁部３５に形成された穴部４３に壁部３５の外側から挿入され、被調整部となる頭部４２ａが壁部３５の外面に重ねられて位置し、軸部４２ｂが配置部３３の内部に延びて受け部材２７の中央部の螺合穴２７ａに螺合されている。すなわち、調整部材４２は、被調整部となる頭部４２ａが回動体５の本体部１３の外側に露出する。穴部４３は壁部３５の中央部に位置する。すなわち、穴部４３は、回動体５つまり本体部１３の回動中心に位置する。穴部４３は、円形状に形成されている。図示される例では、穴部４３の周囲に保持部３６が位置する。そのため、穴部４３に挿入された調整部材４２は、軸部４２ｂが押し付け部材２６に挿通されている。 Preferably, the torque setting section 24 has an adjustment member 42 that adjusts the position of the receiving member 27 . The adjusting member 42 is operably arranged with respect to the arrangement portion 33 of the main body portion 13 . In the present embodiment, the adjusting member 42 is a bolt that is screwed onto the receiving member 27 so that the position of the receiving member 27 can be finely adjusted in the advancing/retreating direction according to the rotation of the adjusting member 42 . The adjusting member 42 is inserted from the outside of the wall portion 35 into the hole portion 43 formed in the wall portion 35, and the head portion 42a, which is the portion to be adjusted, is positioned so as to overlap the outer surface of the wall portion 35, and the shaft portion 42b is positioned. It extends inside the placement portion 33 and is screwed into the screw hole 27 a in the central portion of the receiving member 27 . That is, the adjusting member 42 exposes the head portion 42a, which is the portion to be adjusted, to the outside of the body portion 13 of the rotating body 5. As shown in FIG. Hole 43 is located in the center of wall 35 . That is, the hole portion 43 is positioned at the rotation center of the rotating body 5 , that is, the main body portion 13 . The hole 43 is formed in a circular shape. In the illustrated example, the holding portion 36 is positioned around the hole portion 43 . Therefore, the adjusting member 42 inserted into the hole 43 has the shaft portion 42 b inserted through the pressing member 26 .

次に、一実施の形態の作用を説明する。 Next, the operation of one embodiment will be described.

回動体５をケース体２に取り付ける際には、予め形成された本体部１３の配置部３３の内部に押し付け部材２６を挿入して一端部を保持部３６に保持し、押し付け部材２６の他端部に別途形成された受け部材２７を取り付ける。次いで、調整部材４２を穴部４３に挿入し、受け部材２７に螺着させる。さらに、予め形成された摺動部材２８を配置部３３の内方から延出部３７の受け穴部３８に挿入し、受け部材２７の接触部３０と摺動部材２８の各接触部３１とを当接させる。この後、延出部３７をケース体２の取付穴部１０に内挿しつつ、係止部４０を取付穴部１０に係止する。この状態で、支持部が対向面１４に接触し、摺動部材２８がそれぞれ取付穴部１０の内面に接触して、回動体５がケース体２の被取付部７に取り付けられた状態となる。 When the rotating body 5 is attached to the case body 2, the pressing member 26 is inserted into the arrangement portion 33 of the body portion 13 formed in advance, one end thereof is held by the holding portion 36, and the other end of the pressing member 26 is held. A separately formed receiving member 27 is attached to the part. Next, the adjusting member 42 is inserted into the hole 43 and screwed onto the receiving member 27 . Further, the pre-formed sliding member 28 is inserted into the receiving hole portion 38 of the extending portion 37 from the inside of the placement portion 33, and the contact portion 30 of the receiving member 27 and each contact portion 31 of the sliding member 28 are engaged. abut. After that, the locking portion 40 is locked to the mounting hole portion 10 while inserting the extending portion 37 into the mounting hole portion 10 of the case body 2 . In this state, the supporting portion comes into contact with the facing surface 14, the sliding members 28 come into contact with the inner surfaces of the mounting holes 10, respectively, and the rotating body 5 is attached to the attached portion 7 of the case body 2. .

そして、本実施の形態では、押し付け部材２６の付勢により受け部材２７を摺動部材２８に押し付けることで、受け部材２７を摺動部材２８に対して安定的に押し付けることができ、その受け部材２７の押し付けによって摺動部材２８が被取付部７の取付穴部１０の内面に圧接されるので、摺動部材２８を被取付部７に対して安定的に圧接させることができる。したがって、その圧接強さに応じて設定される回動体５のトルクが安定し、操作感を向上できる。 In this embodiment, the receiving member 27 can be stably pressed against the sliding member 28 by pressing the receiving member 27 against the sliding member 28 by the biasing force of the pressing member 26. Since the sliding member 28 is pressed against the inner surface of the mounting hole portion 10 of the mounting portion 7 by pressing the sliding member 27 , the sliding member 28 can be stably pressed against the mounting portion 7 . Therefore, the torque of the rotating body 5, which is set according to the pressure contact strength, is stabilized, and the operational feeling can be improved.

特に、押し付け部材２６を金属製のスプリングとすることにより、熱変形の影響を受けにくくなり、トルクをより安定させることができる。 In particular, by using a metal spring as the pressing member 26, it is less likely to be affected by thermal deformation, and torque can be further stabilized.

また、回動体５を被取付部７に組み付けた後でも、トルク設定部２４によってトルクを調整できる。すなわち、本体部１３に動作可能に取り付けた調整部材４２の動作に応じて受け部材２７が進退することにより、調整部材４２を操作することによって受け部材２７の進退位置を容易に微調整できるので、受け部材２７の位置に応じて摺動部材２８の被取付部７への圧接強さを任意に調整して、トルクを高精度に微調整できる。特に、調整部材４２をボルトとすることで、特殊な工具を用いることなく、調整部材４２を容易に操作できる。さらに、回動体５を被取付部７に組み付けた後にトルクを調整できるので、回動体５を被取付部７に組み付ける際にトルクを慎重に設定する必要がなく、組み付け作業が容易になる。そのため、回動体５を安価に組み付けできる。 Further, the torque can be adjusted by the torque setting portion 24 even after the rotating body 5 is attached to the attached portion 7 . That is, since the receiving member 27 advances and retreats according to the operation of the adjusting member 42 operably attached to the main body 13, the advancing and retreating position of the receiving member 27 can be easily finely adjusted by operating the adjusting member 42. By arbitrarily adjusting the pressure contact strength of the sliding member 28 against the mounting portion 7 according to the position of the receiving member 27, the torque can be finely adjusted with high accuracy. In particular, by using a bolt as the adjusting member 42, the adjusting member 42 can be easily operated without using a special tool. Furthermore, since the torque can be adjusted after the rotating body 5 is assembled to the mounted part 7, there is no need to carefully set the torque when the rotating body 5 is assembled to the mounted part 7, and the assembling work is facilitated. Therefore, the rotating body 5 can be assembled at low cost.

また、摺動部材２８を受け部材２７の進退方向と交差する方向に進退可能に配置し、受け部材２７と摺動部材２８との互いに接触する接触部３０，３１の少なくともいずれか一方を受け部材２７の進退方向に対し傾斜して形成して、受け部材２７の進退を摺動部材２８の進退に変換することで、調整部材４２の操作によって受け部材２７を進退させることで摺動部材２８の被取付部７への圧接強さすなわちトルクを調整する構成を簡素に実現できるとともに、傾斜の角度に応じて受け部材２７の進退量と摺動部材２８の進退量との関係を容易に設定できる。 Further, the sliding member 28 is arranged so as to be able to move back and forth in a direction intersecting the advancing and retreating direction of the receiving member 27, and at least one of contact portions 30 and 31 of the receiving member 27 and the sliding member 28 contacting each other. 27 is inclined with respect to the forward/backward direction of the sliding member 27, and the forward/backward movement of the receiving member 27 is converted into the forward/backward movement of the sliding member 28. It is possible to simply realize a configuration for adjusting the pressure contact strength, that is, the torque to the mounted portion 7, and to easily set the relationship between the amount of movement of the receiving member 27 and the amount of movement of the sliding member 28 according to the angle of inclination. .

そして、回動体５は、吹出口装置１の風調整部３を操作するダイヤルなので、風調整部３の操作の際の回動体５の操作感が良好である。特に、温度変化によるトルクの変化が生じにくい上記の回動体５を車両用の吹出口装置１に適用することで、車室内の温度が変化した場合であっても、回動体５の操作感を損なわない吹出口装置１を提供できる。 Further, since the rotating body 5 is a dial for operating the airflow adjusting portion 3 of the outlet device 1, the operational feeling of the rotating body 5 when operating the airflow adjusting portion 3 is good. In particular, by applying the rotating body 5, whose torque is less likely to change due to temperature changes, to the air outlet device 1 for a vehicle, even when the temperature in the passenger compartment changes, the operational feeling of the rotating body 5 can be improved. It is possible to provide an air outlet device 1 that does not spoil.

なお、上記の一実施の形態において、押し付け部材２６を引張スプリングとして、受け部材２７を本体部１３側へと付勢する構成としてもよい。この場合には、接触部３０，３１の傾斜を受け部材２７の進退方向、つまり図１の上下方向に反転させて、受け部材２７の接触部３０を摺動部材２８の接触部３１に対して被取付部７側から接触させることで、同様の作用効果を奏することができる。 In the above embodiment, the pressing member 26 may be a tension spring to urge the receiving member 27 toward the main body 13 side. In this case, the inclination of the contact portions 30 and 31 is reversed in the advancing/retreating direction of the receiving member 27, that is, the vertical direction in FIG. By making contact from the attached portion 7 side, the same effect can be obtained.

また、回動体５は、吹出口装置１の操作用のものとしたが、これに限らず、その他の任意の装置に適用されるダイヤルでもよい。 Further, although the rotating body 5 is for operating the outlet device 1, it is not limited to this, and may be a dial applied to any other device.

本発明は、例えば自動車の空調装置からの空調風の風向や風量を調整するためのダイヤルとして好適に用いることができる。 INDUSTRIAL APPLICABILITY The present invention can be suitably used, for example, as a dial for adjusting the direction and volume of conditioned air from an air conditioner of an automobile.
