ところで、水栓のハンドルには、種類等に応じた様々な形状のものが存在する。そのため、特許文献１の技術を適用する場合、ハンドルの下端に固定できるように、ハンドルの形状に合ったリングをハンドルの形状毎にそれぞれ用意する必要がある。本発明は、こうした実情に鑑みてなされたものであり、その目的は、ハンドルの操作にクリック感等の節度感を付与する節度感付与部材に関して、形状が異なるものの、軸挿入部の形状は共通するハンドルにも共通して用いることができるようにすることにある。 By the way, there are various shapes of faucet handles depending on the type and the like. Therefore, when the technique of Patent Document 1 is applied, it is necessary to prepare a ring matching the shape of the handle for each shape of the handle so that the ring can be fixed to the lower end of the handle. The present invention has been made in view of such circumstances, and an object thereof is to provide a moderation feeling imparting member such as a click feeling to a handle operation, although the shape is different, but the shape of the shaft insertion portion is common. The purpose is to make it possible to use it in common with the handles that are used.

上記課題を解決するための節度感付与部材は、水栓本体の操作軸部に取り付けられた回転操作式のハンドルの節度感付与部材であって、前記ハンドルに取り付けられて、前記ハンドルと一体回転する第１部材と、前記水栓本体に取り付けられる第２部材とを備え、前記第１部材及び前記第２部材には、互いに干渉することで前記ハンドルの回転動作に抵抗を付与する抵抗部が設けられ、前記第１部材は、前記ハンドルにおいて前記操作軸部が挿入される軸挿入部と前記操作軸部との間に装着されて、前記ハンドルに付与された回転力を前記操作軸部に伝達する筒状のアダプタ部分と、前記アダプタ部分よりも径が大きく、前記抵抗部を構成する筒状の本体部分とが一体に設けられており、前記アダプタ部分は、前記軸挿入部に挿入されるとともに、前記アダプタ部分の内周側に前記操作軸部が挿入されることを要旨とする。 The moderation-imparting member for solving the above-mentioned problems is a moderation-imparting member of a rotation-operated handle attached to the operation shaft portion of the faucet body, and is attached to the handle and rotates integrally with the handle. The first member and the second member attached to the faucet main body are provided, and the first member and the second member have a resistance portion that imparts resistance to the rotational operation of the handle by interfering with each other. The first member is provided between the shaft insertion portion into which the operation shaft portion is inserted and the operation shaft portion in the handle, and the rotational force applied to the handle is applied to the operation shaft portion. A tubular adapter portion for transmission and a tubular main body portion having a diameter larger than that of the adapter portion and constituting the resistance portion are integrally provided, and the adapter portion is inserted into the shaft insertion portion. At the same time, the gist is that the operation shaft portion is inserted on the inner peripheral side of the adapter portion .

上記構成においては、ハンドル側に設けられる第１部材について、抵抗部を構成する本体部を、ハンドルにおいて操作軸部が挿入される軸挿入部と操作軸部との間に装着されるアダプタ部分と一体に設けている。一般に、水栓の種類によってハンドルの形状が異なる場合であっても、軸挿入部と操作軸部との間に装着されるアダプタ部材（所謂、ハンドル金具）の形状は共通であることが多い。そのため、アダプタ部材の代わりに第１部材を装着することにより、アダプタ部材と同様に、形状の異なるハンドルにも第１部材を取付けることができる。したがって、形状の異なるハンドルにも共通して適用可能となる。 In the above configuration, regarding the first member provided on the handle side, the main body portion constituting the resistance portion is the adapter portion mounted between the shaft insertion portion and the operation shaft portion into which the operation shaft portion is inserted in the handle. It is provided integrally. In general, even if the shape of the handle differs depending on the type of faucet, the shape of the adapter member (so-called handle metal fitting) mounted between the shaft insertion portion and the operation shaft portion is often the same. Therefore, by mounting the first member instead of the adapter member, the first member can be mounted on handles having different shapes as well as the adapter member. Therefore, it can be applied to handles having different shapes in common.

上記節度感付与部材について、前記第１部材の本体部分は、筒状に構成され、前記第１部材の抵抗部は、前記本体部分の内周及び外周の少なくともいずれかに設けられていることが好ましい。この構成によれば、本体部分の内周や外周における所定の位置に抵抗部を選択的に設けることができる。 Regarding the moderation feeling imparting member, the main body portion of the first member is configured in a cylindrical shape, and the resistance portion of the first member is provided on at least one of the inner circumference and the outer circumference of the main body portion. preferable. According to this configuration, the resistance portion can be selectively provided at a predetermined position on the inner circumference or the outer circumference of the main body portion.

上記節度感付与部材について、前記第１部材の抵抗部は、前記本体部分の軸方向に沿う溝部で構成されていることが好ましい。この構成によれば、ハンドルの回転方向に対して、溝部の延びる方向を直交させることができるため、抵抗部を一定の形状で繰り返し形成することが容易になる。 Regarding the moderation feeling imparting member, it is preferable that the resistance portion of the first member is formed of a groove portion along the axial direction of the main body portion. According to this configuration, since the extending direction of the groove portion can be orthogonal to the rotation direction of the handle, it becomes easy to repeatedly form the resistance portion in a constant shape.

上記節度感付与部材を備えた水栓であることが好ましい。この構成によれば、上記節度感付与部材の機能を奏する水栓とすることができる。 It is preferable that the faucet is provided with the moderation feeling imparting member. According to this configuration, the faucet can function as the moderation-imparting member.

本発明の節度感付与部材によれば、形状が異なるものの、軸挿入部の形状は共通するハンドルに共通して用いることができる。 According to the moderation feeling imparting member of the present invention, although the shape is different, the shape of the shaft insertion portion can be commonly used for a common handle.

At the tip of the extending portion 61a, a convex portion 61b protruding outward in the radial direction is provided. Since the tip of the extending portion 61a is formed at a distance from the outer periphery of the tubular portion 61, it is in a state of having elasticity against a force from the radial direction. The extending portions 61a are provided at two different locations in the circumferential direction of the tubular portion 61.

図６、７に示すように、回転部材５０は、切換ハンドル１８の軸挿入部１８ｃに挿入される筒状のアダプタ部分５１と、アダプタ部分５１の他端側に一体に設けられ、アダプタ部分５１と同軸上、且つアダプタ部分５１よりも径が大きく構成された筒状の本体部分５２とを有する。ここで、「一体に設けられ」とは、アダプタ部分５１と本体部分５２とが一体に成形された態様を意味するとともに、アダプタ部分５１と本体部分５２とが接着剤によって接合された態様や、アダプタ部分５１と本体部分５２とが互いに係合した状態で接続された態様を含むものとする。アダプタ部分５１の外形は、横断面六角形状になっており、切換ハンドル１８の軸挿入部１８ｃに挿入した状態において、軸挿入部１８ｃに嵌合して、切換ハンドル１８と回転部材５０とが一体回転可能となるように構成されている。また、アダプタ部分５１の内径は、切換弁４０の操作軸部４３を挿通可能な大きさであるとともに、図５（ｃ）に示すように、アダプタ部分５１の内周には、操作軸部４３の一端側の外周に設けられた溝部４３ａに嵌合する嵌合溝５１ａが形成されている。 As shown in FIGS. 6 and 7, the rotating member 50 is integrally provided with the tubular adapter portion 51 inserted into the shaft insertion portion 18c of the switching handle 18 and the other end side of the adapter portion 51, and the adapter portion 51. It has a cylindrical main body portion 52 that is coaxial with the adapter portion 51 and has a diameter larger than that of the adapter portion 51. Here, "provided integrally" means an embodiment in which the adapter portion 51 and the main body portion 52 are integrally molded, and also an embodiment in which the adapter portion 51 and the main body portion 52 are joined by an adhesive. It is assumed that the adapter portion 51 and the main body portion 52 are connected in a state of being engaged with each other. The outer shape of the adapter portion 51 has a hexagonal cross section, and when the adapter portion 51 is inserted into the shaft insertion portion 18c of the switching handle 18, it is fitted into the shaft insertion portion 18c and the switching handle 18 and the rotating member 50 are integrated. It is configured to be rotatable. The inner diameter of the adapter portion 51 is large enough to allow the operation shaft portion 43 of the switching valve 40 to be inserted, and as shown in FIG. 5C, the operation shaft portion 43 is formed on the inner circumference of the adapter portion 51. A fitting groove 51a that fits into the groove portion 43a provided on the outer periphery on one end side of the above is formed.

本体部分５２は、その外径が、切換ハンドル１８の筒状部１８ａの内周よりも小径となるように形成されるとともに、その内径が、固定部材６０の延設部６１ａの凸部６１ｂにおける外径よりも僅かに小さくなるように形成されている。また、回転部材５０の本体部分５２の内周には、軸方向に延びる三角溝状の干渉溝５２ａが全周に亘って複数、設けられている。 The main body portion 52 is formed so that its outer diameter is smaller than the inner diameter of the tubular portion 18a of the switching handle 18, and its inner diameter is the convex portion 61b of the extending portion 61a of the fixing member 60. It is formed so as to be slightly smaller than the outer diameter. Further, a plurality of triangular groove-shaped interference grooves 52a extending in the axial direction are provided on the inner circumference of the main body portion 52 of the rotating member 50 over the entire circumference.

次に、節度感付与部材７０を介した切換弁４０と切換ハンドル１８の接続構成について説明する。
図６、７に示すように、まず、切換ハンドル１８の軸挿入部１８ｃに、回転部材５０のアダプタ部分５１を挿入することにより、切換ハンドル１８に対して回転部材５０が一体回転可能に取り付けられる。この際、図５（ｃ）に示すように、回転部材５０の本体部分５２は、大部分が切換ハンドル１８の収容空間Ｓ内に収容された状態となる。 Next, a connection configuration between the switching valve 40 and the switching handle 18 via the moderation feeling imparting member 70 will be described.

At this time, as shown in FIG. 5C, most of the main body portion 52 of the rotating member 50 is accommodated in the accommodation space S of the switching handle 18.

また、固定部材６０の筒状部６１の挿通孔に切換弁４０の操作軸部４３を挿入することにより、切換弁４０のケーシング４１の外周に対して固定部材６０が取り付けられる。このとき、切換弁４０のケーシング４１の外周に設けられた溝部４１ｂと、固定部材６０の筒状部の内周に設けられた嵌合溝６１ｃとが嵌合するとともに、固定部材６０の係止部６２が、切換弁４０のケーシング４１の一端側の端面４１ａに当接することにより、固定部材６０は、切換弁４０のケーシング４１に対して相対回転不能に固定される。 Further, by inserting the operation shaft portion 43 of the switching valve 40 into the insertion hole of the tubular portion 61 of the fixing member 60, the fixing member 60 is attached to the outer periphery of the casing 41 of the switching valve 40. At this time, the groove portion 41b provided on the outer periphery of the casing 41 of the switching valve 40 and the fitting groove 61c provided on the inner circumference of the tubular portion of the fixing member 60 are fitted and the fixing member 60 is locked. When the portion 62 abuts on the end surface 41a on one end side of the casing 41 of the switching valve 40, the fixing member 60 is fixed to the casing 41 of the switching valve 40 so as not to rotate relative to each other.

次に、切換ハンドル１８に取り付けられた回転部材５０のアダプタ部分５１に、固定部材６０が取り付けられた切換弁４０の操作軸部４３を挿入することにより、回転部材５０を介して、切換弁４０の操作軸部４３に対して切換ハンドル１８が取り付けられる。このとき、切換弁４０の操作軸部４３の外周に設けられた溝部４３ａと、回転部材５０のアダプタ部分５１の内周に設けられた嵌合溝５１ａとが嵌合することにより、切換ハンドル１８及び回転部材５０は、切換弁４０の操作軸部４３に対して一体回転可能に固定される。 Next, by inserting the operation shaft portion 43 of the switching valve 40 to which the fixing member 60 is attached into the adapter portion 51 of the rotating member 50 attached to the switching handle 18, the switching valve 40 is inserted via the rotating member 50. The switching handle 18 is attached to the operation shaft portion 43 of the above. At this time, the groove portion 43a provided on the outer periphery of the operation shaft portion 43 of the switching valve 40 and the fitting groove 51a provided on the inner circumference of the adapter portion 51 of the rotating member 50 are fitted to each other, whereby the switching handle 18 The rotary member 50 and the rotary member 50 are integrally rotatably fixed to the operation shaft portion 43 of the switching valve 40.

また、切換弁４０のケーシング４１に取り付けられた固定部材６０は、回転部材５０の本体部分５２の内側に収容された状態となる。そして、回転部材５０の本体部分５２の内周に設けられた干渉溝５２ａに固定部材６０の延設部６１ａの凸部６１ｂが干渉した状態となる。次に、切換ハンドル１８の外面側から切換ハンドル１８の底壁１８ｄの貫通孔１８ｅにネジ（図示せず）を挿入するとともに、切換弁４０の操作軸部４３のネジ孔４３ｂに螺合する。これにより、切換弁４０に対して切換ハンドル１８が抜け止めされた状態で固定される。 Further, the fixing member 60 attached to the casing 41 of the switching valve 40 is housed inside the main body portion 52 of the rotating member 50. Then, the convex portion 61b of the extending portion 61a of the fixing member 60 interferes with the interference groove 52a provided on the inner circumference of the main body portion 52 of the rotating member 50. Next, a screw (not shown) is inserted into the through hole 18e of the bottom wall 18d of the switching handle 18 from the outer surface side of the switching handle 18, and is screwed into the screw hole 43b of the operation shaft portion 43 of the switching valve 40. As a result, the switching handle 18 is fixed to the switching valve 40 in a state of being prevented from coming off.

図８に示すように、節度感付与部材７０を介して切換弁４０に取り付けられた切換ハンドル１８を回転操作すると、回転部材５０の本体部分５２の内周に設けられた干渉溝５２ａと、固定部材６０の延設部６１ａの凸部６１ｂとが干渉することによって抵抗が生じる。したがって、回転部材５０の本体部分５２の内周に設けられた干渉溝５２ａと、固定部材６０の延設部６１ａの凸部６１ｂとによって、互いに干渉することでハンドルの回転動作に抵抗を付与する抵抗部が構成されている。そして、この抵抗部により、回転操作全体にカチカチとした節度感としてのノッチ感が生じる。 As shown in FIG. 8, when the switching handle 18 attached to the switching valve 40 via the moderation feeling imparting member 70 is rotated, it is fixed to the interference groove 52a provided on the inner circumference of the main body portion 52 of the rotating member 50. Resistance is generated by interference with the convex portion 61b of the extending portion 61a of the member 60. Therefore, the interference groove 52a provided on the inner circumference of the main body portion 52 of the rotating member 50 and the convex portion 61b of the extending portion 61a of the fixing member 60 interfere with each other to impart resistance to the rotational operation of the handle. The resistance part is configured. Then, due to this resistance portion, a notch feeling as a feeling of moderation is generated in the entire rotation operation.

本実施形態の作用及び効果について説明する。
（１）切換ハンドル１８に取り付けられる回転部材５０について、アダプタ部分５１よりも径が大きく、抵抗部を構成する筒状の本体部分５２を、切換ハンドル１８において操作軸部４３が挿入される軸挿入部１８ｃと操作軸部４３との間に装着される筒状のアダプタ部分５１と一体に設けている。また、アダプタ部分５１は、軸挿入部１８ｃに挿入されるとともに、アダプタ部分５１の内周側に操作軸部４３が挿入される。一般に、水栓の種類によって切換ハンドル１８の形状が異なる場合であっても、軸挿入部１８ｃと操作軸部４３との間に装着されるアダプタ部材（所謂、ハンドル金具）の形状は共通であることが多い。そのため、アダプタ部材の代わりに回転部材５０を装着することにより、アダプタ部材と同様に、形状が異なるものの、軸挿入部の形状は共通するハンドルにも回転部材５０を取付けることができる。したがって、形状が異なるものの、軸挿入部の形状は共通するハンドルにも共通して適用可能となる。 The operation and effect of this embodiment will be described.
(1) Regarding the rotating member 50 attached to the switching handle 18, a cylindrical main body portion 52 having a diameter larger than that of the adapter portion 51 and constituting a resistance portion is inserted into a shaft in which the operating shaft portion 43 is inserted in the switching handle 18. It is provided integrally with a tubular adapter portion 51 mounted between the portion 18c and the operation shaft portion 43. Further, the adapter portion 51 is inserted into the shaft insertion portion 18c, and the operation shaft portion 43 is inserted into the inner peripheral side of the adapter portion 51. Generally, even if the shape of the switching handle 18 differs depending on the type of faucet, the shape of the adapter member (so-called handle metal fitting) mounted between the shaft insertion portion 18c and the operation shaft portion 43 is the same. Often. Therefore, by mounting the rotary member 50 instead of the adapter member, the rotary member 50 can be mounted on a handle having a common shape of the shaft insertion portion, although the shape is different as in the adapter member. Therefore, although the shapes are different, the shape of the shaft insertion portion can be applied to a common handle in common.

（２）仮に、回転部材５０において、アダプタ部分５１と本体部分５２とが別体で構成され、それぞれが別々に切換ハンドル１８に取り付けられていると、アダプタ部分５１の回転軸と、本体部分５２の回転軸とが一致するように位置決めする必要があるため、構造が複雑になる。これに対し、本実施形態では、回転部材５０におけるアダプタ部分５１と本体部分５２とが一体に設けられているため、切換ハンドル１８の回転軸と回転部材５０の本体部分５２の回転軸を同一軸上とすることが容易になる。 (2) If the adapter portion 51 and the main body portion 52 are separately configured in the rotating member 50 and are separately attached to the switching handle 18, the rotating shaft of the adapter portion 51 and the main body portion 52 are attached. The structure is complicated because it needs to be positioned so as to coincide with the axis of rotation of. On the other hand, in the present embodiment, since the adapter portion 51 and the main body portion 52 of the rotating member 50 are integrally provided, the rotating shaft of the switching handle 18 and the rotating shaft of the main body portion 52 of the rotating member 50 are the same axis. It will be easier to make it on.

（３）回転部材５０の本体部分５２は、大部分が切換ハンドル１８の収容空間Ｓ内に収容された状態となっているため、切換ハンドル１８の外観に影響を与え難くなっている。
（４）回転部材５０と固定部材６０とで構成される節度感付与部材７０は、水栓の外観を構成する部材ではないため、耐久性等の性質を重視した材料選択が可能である。また、仮に、抵抗部が摩耗した場合であっても、節度感付与部材７０のみを交換すればよいため、切換ハンドル１８自体を交換しなくてもよい。 (3) Since most of the main body portion 52 of the rotating member 50 is accommodated in the accommodation space S of the switching handle 18, it is difficult to affect the appearance of the switching handle 18.
(4) Since the moderation-imparting member 70 composed of the rotating member 50 and the fixing member 60 is not a member constituting the appearance of the faucet, it is possible to select a material with an emphasis on properties such as durability. Further, even if the resistance portion is worn, only the moderation feeling imparting member 70 needs to be replaced, so that the switching handle 18 itself does not have to be replaced.

（５）回転部材５０を、既存のアダプタ部材（ハンドル金具）と交換することで、既存の水栓にも、切換ハンドルを交換することなく、後付けで本実施形態の節度感付与部材７０を取付け可能である。 (5) By replacing the rotating member 50 with the existing adapter member (handle metal fitting), the moderation-imparting member 70 of the present embodiment can be retrofitted to the existing faucet without replacing the switching handle. It is possible.

（６）節度感付与部材７０を取付けることによって、切換ハンドル１８に自転防止機能を付与することができる。
（７）回転部材５０の本体部分５２は、筒状に構成され、回転部材５０の抵抗部は、本体部分５２の内周に設けられている。したがって、本体部分５２の内周における所定の位置に抵抗部を選択的に設けることができる。 (6) By attaching the moderation feeling imparting member 70, the rotation prevention function can be imparted to the switching handle 18.
(7) The main body portion 52 of the rotating member 50 is formed in a cylindrical shape, and the resistance portion of the rotating member 50 is provided on the inner circumference of the main body portion 52. Therefore, the resistance portion can be selectively provided at a predetermined position on the inner circumference of the main body portion 52.

（８）回転部材５０の抵抗部は、本体部分５２の軸方向に沿う干渉溝５２ａで構成されている。したがって、切換ハンドル１８の回転方向に対して、溝部の延びる方向を直交させることができるため、抵抗部を一定の形状で繰り返し形成することが容易になる。 (8) The resistance portion of the rotating member 50 is composed of an interference groove 52a along the axial direction of the main body portion 52. Therefore, since the extending direction of the groove portion can be orthogonal to the rotation direction of the switching handle 18, it becomes easy to repeatedly form the resistance portion in a constant shape.

本実施形態は、以下のように変更して実施することができる。本実施形態及び以下の変更例は、技術的に矛盾しない範囲で互いに組み合わせて実施することができる。
・抵抗部として設けられる干渉溝は、回転部材５０の本体部分５２の内周に全周に亘って形成された構成に限定されず、本体部分５２の内周に部分的に形成されていてもよい。例えば、図９に示すように、本体部分５２の内周において、９０度の間隔をおいた４箇所に干渉溝５２ｂが形成されていてもよい。この場合、切換ハンドル１８を回転させると、９０度回転する毎にクリック感が付与され、特定位置に達したことを操作者に伝えることができる。すなわち、抵抗部の形状を適宜選択することにより、回転操作全体にカチカチとしたノッチ感や、特定位置に達したことを操作者に伝えるクリック感といった節度感を付与することができる。 This embodiment can be modified and implemented as follows. The present embodiment and the following modified examples can be implemented in combination with each other within a technically consistent range.
The interference groove provided as the resistance portion is not limited to the configuration formed over the entire circumference of the inner circumference of the main body portion 52 of the rotating member 50, and may be partially formed on the inner circumference of the main body portion 52. good. For example, as shown in FIG. 9, interference grooves 52b may be formed at four locations at intervals of 90 degrees on the inner circumference of the main body portion 52. In this case, when the switching handle 18 is rotated, a click feeling is given every time the switching handle 18 is rotated, and it is possible to inform the operator that a specific position has been reached. That is, by appropriately selecting the shape of the resistance portion, it is possible to give a modest feeling such as a click feeling to the entire rotation operation and a click feeling to inform the operator that a specific position has been reached.

・抵抗部として設けられる干渉溝は、回転部材５０の本体部分５２の軸方向に沿う形状に限定されず、固定部材６０の延設部６１ａの凸部６１ｂと干渉して抵抗が生じる任意の形状を採用することができる。固定部材６０の延設部６１ａの凸部６１ｂと干渉する形状としては、例えば、図１０に示すように、本体部分５２の内周に設けられた複数の凸部５２ｃであってもよい。また、複数の凸部５２ｃに代えて、複数の凹部であってもよく、凸部５２ｃと凹部が混在した形状であってもよい。 The interference groove provided as the resistance portion is not limited to the shape along the axial direction of the main body portion 52 of the rotating member 50, and any shape that interferes with the convex portion 61b of the extending portion 61a of the fixing member 60 to generate resistance. Can be adopted. As a shape that interferes with the convex portion 61b of the extending portion 61a of the fixing member 60, for example, as shown in FIG. 10, a plurality of convex portions 52c provided on the inner circumference of the main body portion 52 may be used. Further, instead of the plurality of convex portions 52c, a plurality of concave portions may be used, or a shape in which the convex portions 52c and the concave portions are mixed may be used.

・本実施形態では、抵抗部として、回転部材５０の本体部分５２の内周に干渉溝５２ａが形成されるとともに、固定部材６０の筒状部６１に凸部６１ｂが形成されていたが、この態様に限定されない。例えば、図１１（ａ）に示すように、回転部材５０の本体部分５２の内周に延設部５２ｄを形成し、この延設部５２ｄの先端に凸部５２ｅが形成されるとともに、図１１（ｂ）に示すように、固定部材６０の筒状部６１の外周に溝部６１ｄが形成されていてもよい。さらに、この場合、図１２に示すように、固定部材６０が切換弁４０と一体に構成されていてもよい。すなわち、切換弁４０のケーシング４１における一端側の外周に形成された溝部４１ｃを、抵抗部として用いてもよい。 -In the present embodiment, as a resistance portion, an interference groove 52a is formed on the inner circumference of the main body portion 52 of the rotating member 50, and a convex portion 61b is formed on the tubular portion 61 of the fixing member 60. It is not limited to the embodiment. For example, as shown in FIG. 11A, an extended portion 52d is formed on the inner circumference of the main body portion 52 of the rotating member 50, and a convex portion 52e is formed at the tip of the extended portion 52d, and FIG. 11 As shown in (b), the groove portion 61d may be formed on the outer periphery of the tubular portion 61 of the fixing member 60. Further, in this case, as shown in FIG. 12, the fixing member 60 may be integrally configured with the switching valve 40. That is, the groove portion 41c formed on the outer periphery of the casing 41 of the switching valve 40 on the one end side may be used as the resistance portion.

・回転部材５０側に設けられる抵抗部は、回転部材５０の本体部分５２の内周に形成された態様に限定されず、本体部分５２の外周に形成されていてもよい。例えば、図１３（ａ）、（ｂ）に示すように、回転部材５０の本体部分５２の外周に軸方向に沿う干渉溝５２ｆを設けるとともに、固定部材６０の筒状部６１から径方向外側に延びた状態で設けられた延設部６１ｅの先端が、回転部材５０の本体部分５２の外周側から干渉溝５２ｆに干渉するように構成してもよい。また、図１４に示すように、回転部材５０のアダプタ部分と本体部分５２とを接続する接続壁５３に、複数の凹部５２ｇを設けるとともに、固定部材６０の係止部６２に複数の凸部６２ａを設け、凹部５２ｇと凸部６２ａとを干渉させてもよい。さらに、この態様において、接続壁５３側に凸部６２ａが設けられ、係止部６２側に凹部５２ｇが設けられていてもよく、接続壁５３と係止部６２の両方に、凸部６２ａと凹部５２ｇが混在して設けられていてもよい。 The resistance portion provided on the rotating member 50 side is not limited to the mode formed on the inner circumference of the main body portion 52 of the rotating member 50, and may be formed on the outer periphery of the main body portion 52. For example, as shown in FIGS. 13A and 13B, an interference groove 52f along the axial direction is provided on the outer periphery of the main body portion 52 of the rotating member 50, and the fixing member 60 is radially outward from the tubular portion 61. The tip of the extending portion 61e provided in the extended state may be configured to interfere with the interference groove 52f from the outer peripheral side of the main body portion 52 of the rotating member 50. Further, as shown in FIG. 14, a plurality of recesses 52g are provided in the connection wall 53 connecting the adapter portion and the main body portion 52 of the rotating member 50, and a plurality of convex portions 62a are provided in the locking portion 62 of the fixing member 60. May be provided so that the concave portion 52g and the convex portion 62a interfere with each other. Further, in this embodiment, the convex portion 62a may be provided on the connection wall 53 side and the concave portion 52g may be provided on the locking portion 62 side. The recesses 52g may be provided in a mixed manner.

・本実施形態では、図５（ｃ）に示すように、切換ハンドル１８の収容空間Ｓに、回転部材５０の本体部分５２の大部分が収容されていたが、収容空間Ｓに本体部分５２の全体が収容されていてもよい。収容空間Ｓに本体部分５２の全体が収容されることにより、回転部材５０をより目立たなくすることができる。また、切換ハンドル１８が収容空間Ｓを有してなく、本体部分５２の全てが切換ハンドル１８から露出した状態であってもよい。 In the present embodiment, as shown in FIG. 5C, most of the main body portion 52 of the rotating member 50 is accommodated in the accommodation space S of the switching handle 18, but the accommodation space S accommodates the main body portion 52. The whole may be contained. By accommodating the entire main body portion 52 in the accommodating space S, the rotating member 50 can be made less conspicuous. Further, the switching handle 18 may not have the accommodation space S, and the entire main body portion 52 may be exposed from the switching handle 18.

・固定部材６０の筒状部６１に設けられる延設部６１ａの形状は、本実施形態の形状に限定されない。回転部材５０の本体部分５２に設けられる干渉溝５２ａと干渉して節度感を付与することができる形状を適宜採用することができる。例えば、図１５に示すように、固定部材６０の外周面に突起部材６１ｆを配置し、この突起部材６１ｆをコイルばね６１ｇによって径方向外側に付勢して、回転部材５０の本体部分５２の干渉溝５２ａと干渉するように構成してもよい。 The shape of the extending portion 61a provided in the tubular portion 61 of the fixing member 60 is not limited to the shape of the present embodiment. A shape that can interfere with the interference groove 52a provided in the main body portion 52 of the rotating member 50 to give a sense of moderation can be appropriately adopted. For example, as shown in FIG. 15, a protrusion member 61f is arranged on the outer peripheral surface of the fixing member 60, and the protrusion member 61f is urged radially outward by a coil spring 61g to interfere with the main body portion 52 of the rotating member 50. It may be configured to interfere with the groove 52a.

・回転部材５０のアダプタ部分５１の外形は横断面六角形状に限定されない。切換ハンドル１８の軸挿入部１８ｃに挿入されて、切換ハンドル１８と一体回転可能であれば、六角形状以外に、多角形状や楕円形等の横断面を適宜採用することができる。 The outer shape of the adapter portion 51 of the rotating member 50 is not limited to the hexagonal cross section. If it is inserted into the shaft insertion portion 18c of the switching handle 18 and can rotate integrally with the switching handle 18, a cross section such as a polygonal shape or an elliptical shape can be appropriately adopted in addition to the hexagonal shape.
