コントロールケーブルのシール構造Control cable seal structure
　本発明は、コントロールケーブルのシール構造に関する。 The present invention relates to a control cable seal structure.
　たとえば、自動二輪車のスロットルグリップによって操作されるスロットルケーブルのように、水が浸入する可能性のある環境において使用されるコントロールケーブルには、コントロールケーブルのアウターケーシング内に水が浸入することを抑制するためにシール部材が設けられている（たとえば、特許文献１参照）。特許文献１に記載された装置は、スロットルグリップおよびスロットルバルブの間に設けられ、インナーケーブルおよびアウターケーシングを有するスロットルケーブルと、ケーブル巻き掛け部を有するスロットルグリップと、アウターケーシングの端部が取り付けられ、インナーケーブルをケーブル巻き掛け部まで案内するスライダとを有している。スライダは、アウターケーシングの端部が取り付けられるケーブル保持部と、ケーブル保持部に設けられた円形の開口から導出されるインナーケーブルをケーブル巻き掛け部に向けて略９０度屈曲して案内する屈曲部とを有している。アウターケーシングの端部には、ケーブル保持部の円形の開口に隣接して防水シールが設けられており、防水シールは、雨水等の水分がアウターケーシングへ浸入することを防いでいる。 Control cables used in environments where water can enter, such as throttle cables operated by the throttle grips of motorcycles, prevent water from entering the outer casing of the control cable.

The embodiments shown below are merely examples, and the seal structure of the control cable of the present invention is not limited to the following embodiments.
　図１は、本実施形態のコントロールケーブルのシール構造（以下、単にシール構造という）が設けられたケーブル操作機構を示す図である。なお、本発明のシール構造の適用対象は、ケーブル操作機構に限定されない。また、以下の例では、ケーブル操作機構が取り付けられる取付対象は、スロットルグリップの回転動作によってコントロールケーブルを操作する自動二輪車である。しかし、ケーブル操作機構が取り付けられる取付対象は自動二輪車に限定されず、水上バイク、雪上バイクなどの鞍乗り型車両の他、シール構造が必要な各種装置であってもよい。 FIG. 1 is a diagram showing a cable operation mechanism provided with a seal structure (hereinafter, simply referred to as a seal structure) for the control cable of the present embodiment. The application target of the seal structure of the present invention is not limited to the cable operation mechanism. Further, in the following example, the attachment target to which the cable operation mechanism is attached is a motorcycle that operates the control cable by the rotational operation of the throttle grip. However, the attachment target to which the cable operation mechanism is attached is not limited to the motorcycle, and may be a saddle-riding vehicle such as a water bike or a snow bike, or various devices requiring a seal structure.
　図１に示されるように、ケーブル操作機構Ｍは、操作部ＯＰ１と、被操作部ＯＰ２と、後述するシール構造１とを有している。シール構造１は、インナーケーブルＣａと、アウターケーシングＣｂ（以下、インナーケーブルＣａおよびアウターケーシングＣｂを合わせてコントロールケーブルＣと呼ぶ）とを有し、操作部ＯＰ１はインナーケーブルＣａを介して被操作部ＯＰ２に接続されている。詳細は後述するが、シール構造１は、図２および図３に示されるように、アウターケーシングＣｂの一端Ｅｂ１から延びるインナーケーブルＣａを操作部ＯＰ１へ案内する案内部材２と、インナーケーブルＣａが摺動するシール部材３とを備えている。 As shown in FIG. 1, the cable operating mechanism M has an operating portion OP1, an operated portion OP2, and a seal structure 1 described later. The seal structure 1 has an inner cable Ca and an outer casing Cb (hereinafter, the inner cable Ca and the outer casing Cb are collectively referred to as a control cable C), and the operation unit OP1 is an operated unit via the inner cable Ca. It is connected to OP2. Although the details will be described later, in the seal structure 1, as shown in FIGS. 2 and 3, the guide member 2 for guiding the inner cable Ca extending from one end Eb1 of the outer casing Cb to the operation unit OP1 and the inner cable Ca slide together. It includes a moving seal member 3.
　インナーケーブルＣａは、図１に示されるように、一端Ｅａ１が操作部ＯＰ１に他端Ｅａ２が被操作部ＯＰ２に接続されている。インナーケーブルＣａは操作部ＯＰ１に加わった操作力を被操作部ＯＰ２に伝達し、操作部ＯＰ１によって被操作部ＯＰ２を遠隔操作する。アウターケーシングＣｂには、図１～図３に示されるように、インナーケーブルＣａが挿通され、インナーケーブルＣａを操作部ＯＰ１近傍から被操作部ＯＰ２の近傍まで、所定の配索経路に沿って案内する。アウターケーシングＣｂの一端Ｅｂ１は、案内部材２に取り付けられ、他端Ｅｂ２は、被操作部ＯＰ２の近傍に取り付けられている。アウターケーシングＣｂの配索経路は特に限定されないが、本実施形態では、アウターケーシングＣｂは、図１に示されるように、操作部ＯＰ１から下方に延びて、被操作部ＯＰ２に到達するまでの間に、少なくとも１か所で上向きに延びるように配索され、取付対象（本実施形態では車体Ｂ）に取り付けられている。なお、本実施形態では、図２に示されるように、インナーケーブルＣａは、２つのインナーケーブルＣａ１、Ｃａ２を有し、アウターケーシングＣｂは、２つのインナーケーブルＣａ１、Ｃａ２のそれぞれが挿通される２つのアウターケーシングＣｂ１、Ｃｂ２を有している。しかし、インナーケーブルＣａおよびアウターケーシングＣｂの数は特に限定されない。 As shown in FIG. 1, the inner cable Ca has one end Ea1 connected to the operating portion OP1 and the other end Ea2 connected to the operated portion OP2. The inner cable Ca transmits the operating force applied to the operating unit OP1 to the operated unit OP2, and the operating unit OP1 remotely controls the operated unit OP2. As shown in FIGS. 1 to 3, an inner cable Ca is inserted into the outer casing Cb to guide the inner cable Ca from the vicinity of the operating portion OP1 to the vicinity of the operated portion OP2 along a predetermined routing path. To do. One end Eb1 of the outer casing Cb is attached to the guide member 2, and the other end Eb2 is attached in the vicinity of the operated portion OP2. The routing route of the outer casing Cb is not particularly limited, but in the present embodiment, as shown in FIG. 1, the outer casing Cb extends downward from the operating portion OP1 until it reaches the operated portion OP2. In addition, it is arranged so as to extend upward at at least one place, and is attached to the attachment target (vehicle body B in this embodiment). In the present embodiment, as shown in FIG. 2, the inner cable Ca has two inner cables Ca1 and Ca2, and the outer casing Cb is inserted with the two inner cables Ca1 and Ca2, respectively. It has two outer casings Cb1 and Cb2. However, the number of the inner cable Ca and the outer casing Cb is not particularly limited.
　操作部ＯＰ１は、被操作部ＯＰ２を動作させるために操作される。操作部ＯＰ１には、インナーケーブルＣａの一端Ｅａ１が接続されており、操作部ＯＰ１の操作力がインナーケーブルＣａを介して被操作部ＯＰ２に伝達される。 The operation unit OP1 is operated to operate the operated unit OP2. One end Ea1 of the inner cable Ca is connected to the operation unit OP1, and the operating force of the operation unit OP1 is transmitted to the operated unit OP2 via the inner cable Ca.
　操作部ＯＰ１は、インナーケーブルＣａを介して被操作部ＯＰ２を操作することができる構造であれば、特に限定されず、被操作部ＯＰ２は操作部ＯＰ１の操作によってインナーケーブルＣａを介して操作される構造であれば特に限定されない。本実施形態では、図１に示されるように、操作部ＯＰ１はスロットルグリップＧであり、被操作部ＯＰ２はスロットルバルブＶである。本実施形態では、スロットルグリップＧの回転操作によって、インナーケーブルＣ１が操作されて、被操作部ＯＰ２である、スロットルバルブＶが開閉操作され、エンジンに供給される空気量が調整される。 The operation unit OP1 is not particularly limited as long as it has a structure in which the operated unit OP2 can be operated via the inner cable Ca, and the operated unit OP2 is operated via the inner cable Ca by the operation of the operation unit OP1. The structure is not particularly limited. In the present embodiment, as shown in FIG. 1, the operation unit OP1 is the throttle grip G, and the operated unit OP2 is the throttle valve V. In the present embodiment, the inner cable C1 is operated by the rotation operation of the throttle grip G, the throttle valve V, which is the operated portion OP2, is opened and closed, and the amount of air supplied to the engine is adjusted.
　スロットルグリップＧは、図３に二点鎖線で示されるパイプＰに対して回転可能に設けられている。スロットルグリップＧは、運転者によって操作されるグリップ部Ｇａと、グリップ部Ｇａの一方の端部側に、インナーケーブルＣａの一端Ｅａ１が接続されるケーブル巻掛部Ｗを有している。ケーブル巻掛部Ｗには、案内部材２によって案内されたインナーケーブルＣａの一部が巻き掛けられて、インナーケーブルＣａの一端Ｅａ１が取り付けられる。ケーブル巻掛部Ｗは、スロットルグリップＧとともにスロットルグリップＧの軸周りに回転する。本実施形態では、ケーブル巻掛部Ｗには、２本のインナーケーブルＣａ１、Ｃａ２が取り付けられている。ケーブル巻掛部Ｗは、本実施形態では、図４に示されるように、スロットルグリップＧの軸周り方向に延びる、インナーケーブルＣａ１、Ｃａ２が巻掛けられる巻回部Ｗａと、インナーケーブルＣａ１、Ｃａ２の一端部Ｅａ１がそれぞれ係合する第１係合部Ｗｂ１および第２係合部Ｗｂ２とを有している。 The throttle grip G is rotatably provided with respect to the pipe P shown by the alternate long and short dash line in FIG. The throttle grip G has a grip portion Ga operated by the driver and a cable winding portion W to which one end Ea1 of the inner cable Ca is connected to one end side of the grip portion Ga. A part of the inner cable Ca guided by the guide member 2 is wound around the cable winding portion W, and one end Ea1 of the inner cable Ca is attached. The cable winding portion W rotates around the axis of the throttle grip G together with the throttle grip G. In the present embodiment, two inner cables Ca1 and Ca2 are attached to the cable winding portion W. In the present embodiment, the cable winding portion W includes a winding portion Wa around which the inner cables Ca1 and Ca2 are wound and the inner cables Ca1 and Ca2 extending in the axial direction of the throttle grip G, as shown in FIG. It has a first engaging portion Wb1 and a second engaging portion Wb2 with which one end portion Ea1 of the above is engaged, respectively.
　インナーケーブルＣａは、スロットルグリップＧおよびケーブル巻掛部Ｗが一方に回転したときにスロットルバルブＶを開放させ、スロットルグリップＧおよびケーブル巻掛部Ｗが他方に回転したときにスロットルバルブＶを閉鎖させるように動作する。たとえば、運転者がスロットルグリップＧを手前に回転させて、図４においてケーブル巻掛部Ｗが反時計方向に回転したときに、一方のインナーケーブルＣａ１がケーブル巻掛部Ｗの巻回部Ｗａに巻き取られて引き操作されて、一方のインナーケーブルＣａ１の他端Ｅａ２によってスロットルバルブＶが開放する。このとき、他方のインナーケーブルＣａ２は、ケーブル巻掛部Ｗの巻回部Ｗａから繰り出されて、一方のインナーケーブルＣａ１とは反対方向に動作する。また、自動二輪車の減速時など、運転者がスロットルグリップＧを加速時とは反対側に回転させて、図４においてケーブル巻掛部Ｗが時計方向に回転したときに、他方のインナーケーブルＣａ２がケーブル巻掛部Ｗの巻回部Ｗａに巻き取られて引き操作されて、他方のインナーケーブルＣａ２の他端Ｅａ２によってスロットルバルブＶが閉鎖される。このとき、一方のインナーケーブルＣａ１は、ケーブル巻掛部Ｗの巻回部Ｗａから繰り出されて、他方のインナーケーブルＣａ２とは反対方向に動作する。なお、ケーブル巻掛部Ｗの形状や構造は、スロットルグリップＧ等の操作部ＯＰ１の操作によってインナーケーブルＣａを操作してスロットルバルブＶ等の被操作部ＯＰ２を操作することができれば、特に限定されない。 The inner cable Ca opens the throttle valve V when the throttle grip G and the cable winding portion W rotate in one direction, and closes the throttle valve V when the throttle grip G and the cable winding portion W rotate in the other direction. Works like this. For example, when the driver rotates the throttle grip G toward you and the cable winding portion W rotates counterclockwise in FIG. 4, one inner cable Ca1 becomes the winding portion Wa of the cable winding portion W. The throttle valve V is opened by the other end Ea2 of one inner cable Ca1 after being wound and pulled. At this time, the other inner cable Ca2 is unwound from the winding portion Wa of the cable winding portion W and operates in the direction opposite to that of the one inner cable Ca1. Further, when the driver rotates the throttle grip G on the opposite side to the side when accelerating, such as when decelerating a motorcycle, and the cable winding portion W rotates clockwise in FIG. 4, the other inner cable Ca2 is moved. The throttle valve V is closed by the other end Ea2 of the other inner cable Ca2 after being wound around the winding portion Wa of the cable winding portion W and pulled. At this time, one inner cable Ca1 is unwound from the winding portion Wa of the cable winding portion W and operates in the opposite direction to the other inner cable Ca2. The shape and structure of the cable winding portion W are not particularly limited as long as the inner cable Ca can be operated by operating the operating portion OP1 such as the throttle grip G to operate the operated portion OP2 such as the throttle valve V. ..
　本実施形態では、操作部ＯＰ１は、案内部材２を収容するハウジングＨに対して相対移動可能に設けられている。具体的には、操作部ＯＰ１であるスロットルグリップＧは、ハウジングＨに対して回転可能に取り付けられている。本実施形態では、スロットルグリップＧの端部に設けられたケーブル巻掛部Ｗおよび案内部材２がハウジングＨ内に収容され、グリップ部Ｇａとケーブル巻掛部ＷがハウジングＨに対して回転する。ハウジングＨは、本実施形態では、図４に示されるように、一対の半割状のハウジング部材Ｈａ、Ｈｂによって構成され、一対のハウジング部材Ｈａ、Ｈｂによって案内部材２およびケーブル巻掛部Ｗが挟持されている（図２参照）。 In the present embodiment, the operation unit OP1 is provided so as to be movable relative to the housing H accommodating the guide member 2. Specifically, the throttle grip G, which is the operation unit OP1, is rotatably attached to the housing H. In the present embodiment, the cable winding portion W and the guide member 2 provided at the end of the throttle grip G are housed in the housing H, and the grip portion Ga and the cable winding portion W rotate with respect to the housing H. In the present embodiment, as shown in FIG. 4, the housing H is composed of a pair of half-split housing members Ha and Hb, and the pair of housing members Ha and Hb form a guide member 2 and a cable winding portion W. It is sandwiched (see FIG. 2).
　シール構造１は、上述したように、インナーケーブルＣａと、アウターケーシングＣｂと、案内部材２と、シール部材３とを有している。シール構造１は、アウターケーシングＣｂから導出されたインナーケーブルＣａを伝って水分がアウターケーシングＣｂ内に浸入することを抑制する。本実施形態では、シール構造１は、アウターケーシングＣｂの両端Ｅｂ１、Ｅｂ２のうち、操作部ＯＰ１側の一端Ｅｂ１から水分が侵入することを抑制している。より具体的には、シール構造１は、ハウジングＨおよびスロットルグリップＧのように、操作部ＯＰ１が取付対象に対して相対移動する構造など、シールが困難な隙間を有する構造において、アウターケーシングＣｂに水分が浸入することを抑制している。本実施形態では、操作部ＯＰ１の近傍にシール構造１が設けられていることによって、取付対象と操作部ＯＰ１との間の隙間から侵入する水分がアウターケーシングＣｂ内に浸入することが効果的に抑制される。 As described above, the seal structure 1 has an inner cable Ca, an outer casing Cb, a guide member 2, and a seal member 3. The seal structure 1 prevents water from entering the outer casing Cb through the inner cable Ca led out from the outer casing Cb. In the present embodiment, the seal structure 1 suppresses the intrusion of water from one end Eb1 on the operation unit OP1 side of both ends Eb1 and Eb2 of the outer casing Cb. More specifically, the seal structure 1 is provided on the outer casing Cb in a structure having a gap that is difficult to seal, such as a structure in which the operation unit OP1 moves relative to the mounting target, such as the housing H and the throttle grip G. It suppresses the ingress of water. In the present embodiment, since the seal structure 1 is provided in the vicinity of the operation unit OP1, it is effective that the moisture entering from the gap between the mounting target and the operation unit OP1 penetrates into the outer casing Cb. It is suppressed.
　案内部材２は、図２、図３、図５および図６に示されるように、アウターケーシングＣｂの一端Ｅｂ１が取り付けられるとともに、アウターケーシングＣｂの一端Ｅｂ１から導出されたインナーケーブルＣａを操作部ＯＰ１へ向かって案内する。本実施形態では、案内部材２は、一対のアウターケーシングＣｂ１、Ｃｂ２の一端Ｅｂ１を支持し、一対のインナーケーブルＣａ１、Ｃａ２をケーブル巻掛部Ｗの巻回部Ｗａへと案内している。案内部材２は、本実施形態では、図２および図３に示されるように、操作部ＯＰ１に隣接して配置される。具体的には、ハウジングＨ内においてケーブル巻掛部Ｗに隣接して配置されている。案内部材２は、ハウジングＨ内の空間に保持されて、ハウジングＨが取付対象の所定の位置（自動二輪車の車体ＢのスロットルグリップＧ近傍の位置）に取り付けられることによって、所定の位置で保持される。案内部材２の材料は特に限定されないが、たとえば、硬質樹脂とすることができる。 As shown in FIGS. 2, 3, 5 and 6, the guide member 2 is attached with one end Eb1 of the outer casing Cb, and the inner cable Ca derived from one end Eb1 of the outer casing Cb is attached to the operation unit OP1. I will guide you towards. In the present embodiment, the guide member 2 supports one end Eb1 of the pair of outer casings Cb1 and Cb2, and guides the pair of inner cables Ca1 and Ca2 to the winding portion Wa of the cable winding portion W. In the present embodiment, the guide member 2 is arranged adjacent to the operation unit OP1 as shown in FIGS. 2 and 3. Specifically, it is arranged adjacent to the cable winding portion W in the housing H. The guide member 2 is held in the space inside the housing H, and is held at a predetermined position by mounting the housing H at a predetermined position to be mounted (a position near the throttle grip G of the vehicle body B of the motorcycle). To. The material of the guide member 2 is not particularly limited, but may be, for example, a hard resin.
　案内部材２は、図５および図７に示されるように、基部２１と、基部２１の一方側に設けられ、アウターケーシングＣｂの一端Ｅｂ１が接続される接続部２２と、接続部２２に接続したアウターケーシングＣｂに挿通されたインナーケーブルＣａが導出される導出部２３と、基部２１の他方側に設けられ、インナーケーブルＣａを湾曲して案内する案内部２４とを有している。 As shown in FIGS. 5 and 7, the guide member 2 is provided on one side of the base 21 and the base 21, and is connected to the connecting portion 22 to which one end Eb1 of the outer casing Cb is connected and the connecting portion 22. It has a lead-out portion 23 from which the inner cable Ca inserted into the outer casing Cb is led out, and a guide portion 24 provided on the other side of the base portion 21 to guide the inner cable Ca by bending.
　基部２１は、一方側に接続部２２が設けられ、他方側に案内部２４が設けられる案内部材２のベースとなる部位である。基部２１の全体形状は特に限定されないが、本実施形態では、基部２１は、導出部２３と案内部２４との間に直線配索部ＳＴ（図５および図６参照）を有している。直線配索部ＳＴは、本実施形態では、基部２１に形成された空間部ＳＰを有している。基部２１は、基部２１の下側において開口した開口部Ａ１と、基部２１の上側において開口した第２開口部Ａ２とを有し、上下方向に貫通した矩形枠状に形成されている。なお、本明細書において「上」、「下」という場合、シール構造１が取付対象に取り付けられた状態における鉛直方向上下をいう。また、図に示す基部２１を含む案内部材２の形状はあくまで一例であり、案内部材の形状は図示された形状に限定されるものではない。基部２１の詳細については後述する。 The base portion 21 is a portion that serves as a base for a guide member 2 provided with a connecting portion 22 on one side and a guide portion 24 on the other side. The overall shape of the base portion 21 is not particularly limited, but in the present embodiment, the base portion 21 has a linear routing portion ST (see FIGS. 5 and 6) between the lead-out portion 23 and the guide portion 24. In the present embodiment, the straight line arrangement portion ST has a space portion SP formed in the base portion 21.

As shown in FIG. 5, the connecting portion 22 has an internal space 22a in which one end Eb1 of the outer casing Cb is arranged, and the internal space 22a of the connecting portion 22 is an insertion hole 231 of the lead-out portion 23 described later. It communicates with. The number of outer casings Cb connected to the connecting portion 22 is not particularly limited, but in the present embodiment, the two outer casings Cb1 and Cb2 are connected to the connecting portion 22. The method of connecting the outer casing Cb in the connecting portion 22 is not particularly limited, and the outer casing Cb can be fixed by a known fixing method such as fitting joint, caulking, or adhesive.
　導出部２３は、アウターケーシングＣｂの一端Ｅｂ１から出たインナーケーブルＣａがシール部材３側へと導出される部位である。導出部２３はインナーケーブルＣａが挿通される挿通孔２３１を有している。挿通孔２３１は、図５および図６に示されるように、アウターケーシングＣｂの軸Ｘ方向に沿って延びている。挿通孔２３１の軸Ｘ方向で一端は、接続部２２の内部空間２２ａに連通し、挿通孔２３１の他端はシール部材３の貫通孔３１に連通している。また、本実施形態では、図３、図５および図６に示されるように、導出部２３にはシール部材３が取り付けられ、シール部材３より案内部２４側のインナーケーブルＣａを伝って導出部２３側へ水分が浸入することが抑制される。本実施形態では、導出部２３は、シール部材３が取り付けられるシール部材取付部２３２を有している。 The lead-out portion 23 is a portion where the inner cable Ca protruding from one end Eb1 of the outer casing Cb is led out to the seal member 3 side. The lead-out unit 23 has an insertion hole 231 through which the inner cable Ca is inserted. The insertion hole 231 extends along the axis X direction of the outer casing Cb, as shown in FIGS. 5 and 6. One end of the insertion hole 231 in the axis X direction communicates with the internal space 22a of the connecting portion 22, and the other end of the insertion hole 231 communicates with the through hole 31 of the seal member 3. Further, in the present embodiment, as shown in FIGS. 3, 5 and 6, a seal member 3 is attached to the lead-out portion 23, and the lead-out portion is transmitted from the seal member 3 along the inner cable Ca on the guide portion 24 side. Moisture infiltration to the 23 side is suppressed. In the present embodiment, the lead-out portion 23 has a seal member attachment portion 232 to which the seal member 3 is attached.
　シール部材取付部２３２は、シール部材３が取り付けられる部位である。本実施形態では、シール部材取付部２３２は、軸Ｘ方向で導出部２３の端部に設けられている。本実施形態では、シール部材取付部２３２は、シール部材３を着脱可能であり、シール部材３は、シール部材取付部２３２を介して案内部材２に対して取り付けることができる。また、シール部材３は、所定期間使用された後にインナーケーブルＣａと共に交換するなど、案内部材２から取り外されて、別のシール部材３と交換することができる。 The seal member mounting portion 232 is a portion to which the seal member 3 is mounted. In the present embodiment, the seal member mounting portion 232 is provided at the end of the lead-out portion 23 in the axis X direction. In the present embodiment, the seal member mounting portion 232 can be attached to and detached from the seal member 3, and the seal member 3 can be attached to the guide member 2 via the seal member mounting portion 232. Further, the seal member 3 can be removed from the guide member 2 and replaced with another seal member 3, such as being replaced with the inner cable Ca after being used for a predetermined period of time.
　シール部材取付部２３２の形状や構造は、シール部材３を着脱可能であれば特に限定されない。本実施形態では、シール部材取付部２３２は、シール部材３をアウターケーシングＣｂの軸Ｘ方向に係合可能な係合部２３２ａを有している。シール部材取付部２３２の係合部２３２ａは後述するシール部材３の被係合部３２に係合する。これにより、インナーケーブルＣａがシール部材３に対して軸Ｘ方向に摺動するときに、シール部材３が導出部２３から外れることが抑制される。 The shape and structure of the seal member mounting portion 232 are not particularly limited as long as the seal member 3 can be attached and detached. In the present embodiment, the seal member mounting portion 232 has an engaging portion 232a capable of engaging the seal member 3 in the axis X direction of the outer casing Cb. The engaging portion 232a of the sealing member mounting portion 232 engages with the engaged portion 32 of the sealing member 3 described later. As a result, when the inner cable Ca slides with respect to the seal member 3 in the axis X direction, the seal member 3 is prevented from coming off from the lead-out portion 23.
　係合部２３２ａの形状は、係合部２３２ａがシール部材３の被係合部３２と係合することができ、シール部材取付部２３２からのシール部材３の外れを抑制することができれば、特に限定されない。本実施形態では、導出部２３の一部が、基部２１の接続部２２側の壁部２１ａ（図７参照）から軸Ｘ方向に突出した突出部ＰＲを形成し、当該突出部ＰＲに軸Ｘ方向に垂直に延びる係合部２３２ａが形成されている。より具体的には、係合部２３２ａは、小径部ＰＲ１と大径部ＰＲ２とによって構成された突出部ＰＲのうち、小径部ＰＲ１と大径部ＰＲ２との間に軸Ｘ方向に形成された段差部として形成されている。 The shape of the engaging portion 232a is particularly high as long as the engaging portion 232a can engage with the engaged portion 32 of the seal member 3 and the disengagement of the seal member 3 from the seal member mounting portion 232 can be suppressed. Not limited. In the present embodiment, a part of the lead-out portion 23 forms a protruding portion PR protruding in the axis X direction from the wall portion 21a (see FIG. 7) on the connecting portion 22 side of the base portion 21, and the shaft X is formed on the protruding portion PR. An engaging portion 232a extending vertically in the direction is formed. More specifically, the engaging portion 232a is formed in the axis X direction between the small diameter portion PR1 and the large diameter portion PR2 of the protruding portion PR composed of the small diameter portion PR1 and the large diameter portion PR2. It is formed as a stepped portion.
　案内部２４は、導出部２３およびシール部材３から導出されたインナーケーブルＣａを操作部ＯＰ１に向かって案内する。本実施形態では、案内部２４は、図４に示されるように、一対のインナーケーブルＣａ１、Ｃａ２のそれぞれをケーブル巻掛部Ｗに向かって案内している。本実施形態では、案内部２４は、一対のインナーケーブルＣａ１、Ｃａ２が互いに逆方向にケーブル巻掛部Ｗに巻き付けられるように、それぞれのインナーケーブルＣａ１、Ｃａ２を所定の方向に案内している。これにより、上述したように、ケーブル巻掛部Ｗが一方向に回転したときに、一方のインナーケーブルＣａ１がケーブル巻掛部Ｗに巻き取られ、他方のインナーケーブルＣａ２がケーブル巻掛部Ｗから繰り出されて、スロットルバルブＶを開放させることができる。 The guide unit 24 guides the inner cable Ca derived from the lead-out unit 23 and the seal member 3 toward the operation unit OP1. In the present embodiment, as shown in FIG. 4, the guide portion 24 guides each of the pair of inner cables Ca1 and Ca2 toward the cable winding portion W. In the present embodiment, the guide portion 24 guides the inner cables Ca1 and Ca2 in a predetermined direction so that the pair of inner cables Ca1 and Ca2 are wound around the cable winding portion W in opposite directions. As a result, as described above, when the cable winding portion W rotates in one direction, one inner cable Ca1 is wound around the cable winding portion W, and the other inner cable Ca2 is wound from the cable winding portion W. The throttle valve V can be opened by being fed out.
　本実施形態では、案内部２４は、図５～図７に示されるように、インナーケーブルＣａを案内する湾曲経路２４１を有している。これにより、インナーケーブルＣａは操作部ＯＰ１に向かって湾曲して案内される。本実施形態では、案内部２４は、導出部２３の挿通孔２３１の軸（アウターケーシングＣｂの軸Ｘと同軸）の延長線上に位置する導入部２４２を有している。導入部２４２まで直線的に延びるインナーケーブルＣａは、湾曲経路２４１に沿って操作部ＯＰ１に向かって湾曲して案内される。本実施形態では、案内部２４は、一対のインナーケーブルＣａ１、Ｃａ２をそれぞれ案内する一対の湾曲経路２４１ａ、２４１ｂを有している。湾曲経路２４１ａ、２４１ｂは、図５～図７に示されるように、インナーケーブルＣａ１、Ｃａ２の延在方向を、軸Ｘに対して略９０°方向転換させ、かつ、一対のインナーケーブルＣａ１、Ｃａ２がケーブル巻掛部Ｗに近付くにつれて互いに離れるように、インナーケーブルＣａ１、Ｃａ２を案内している。 In the present embodiment, the guide unit 24 has a curved path 241 that guides the inner cable Ca, as shown in FIGS. 5 to 7. As a result, the inner cable Ca is curved and guided toward the operation unit OP1. In the present embodiment, the guide portion 24 has an introduction portion 242 located on an extension line of the shaft (coaxial with the shaft X of the outer casing Cb) of the insertion hole 231 of the lead-out portion 23. The inner cable Ca that extends linearly to the introduction portion 242 is curved and guided toward the operation portion OP1 along the curved path 241. In the present embodiment, the guide portion 24 has a pair of curved paths 241a and 241b that guide the pair of inner cables Ca1 and Ca2, respectively. As shown in FIGS. 5 to 7, the curved paths 241a and 241b change the extending direction of the inner cables Ca1 and Ca2 by approximately 90 ° with respect to the axis X, and the pair of inner cables Ca1 and Ca2. The inner cables Ca1 and Ca2 are guided so that they are separated from each other as they approach the cable winding portion W.
　シール部材３は、インナーケーブルＣａを伝ってアウターケーシングＣｂ内へ水分が浸入することを抑制する。シール部材３は、図５および図６に示されるように、インナーケーブルＣａが摺動するように構成された貫通孔３１を有している。シール部材３は、インナーケーブルＣａが貫通孔３１内を摺動可能な状態で、インナーケーブルＣａを伝った水分がアウターケーシングＣｂの一端Ｅｂ１に設けられた開口からアウターケーシングＣｂの内部空洞へ水分が浸入することを抑制している。貫通孔３１は、図５および図６に示されるように、導出部２３の挿通孔２３１と連通する導出部側開口３１ａと、基部２１の空間部ＳＰ（直線配索部ＳＴ）に開口する案内部側開口３１ｂとを有している。貫通孔３１は、図５および図６に示されるように、インナーケーブルＣａの外周に密着する部分と、外周に非接触の部分とが軸Ｘ方向で交互に形成されている。これにより、インナーケーブルＣａを軸Ｘ方向に摺動しやすくするとともに、インナーケーブルＣａの外周に密着する部分が変形しやすく、シール性能を向上させることができる。シール部材３の材料は特に限定されないが、本実施形態では、シール部材３は、たとえばゴムなど、弾性材料により構成されている。これにより、シール部材３は、インナーケーブルＣａの動作に応じて追従可能となり、シール性が向上する。 The seal member 3 suppresses the infiltration of water into the outer casing Cb along the inner cable Ca. As shown in FIGS. 5 and 6, the seal member 3 has a through hole 31 configured so that the inner cable Ca slides. In the seal member 3, in a state where the inner cable Ca can slide in the through hole 31, the moisture transmitted through the inner cable Ca flows from the opening provided at one end Eb1 of the outer casing Cb to the inner cavity of the outer casing Cb. It suppresses intrusion. As shown in FIGS. 5 and 6, the through hole 31 is a guide that opens into the lead-out portion side opening 31a that communicates with the insertion hole 231 of the lead-out portion 23 and the space portion SP (straight line arrangement portion ST) of the base portion 21. It has a portion side opening 31b. As shown in FIGS. 5 and 6, the through hole 31 is formed with a portion that is in close contact with the outer circumference of the inner cable Ca and a portion that is not in contact with the outer circumference alternately in the axis X direction. As a result, the inner cable Ca can be easily slid in the axis X direction, and the portion in close contact with the outer circumference of the inner cable Ca can be easily deformed, so that the sealing performance can be improved. The material of the seal member 3 is not particularly limited, but in the present embodiment, the seal member 3 is made of an elastic material such as rubber. As a result, the seal member 3 can follow the operation of the inner cable Ca, and the sealability is improved.
　上述したように、シール部材３は、後述する直線配索部ＳＴ側での導出部２３の端部に設けられている。具体的には、シール部材３は、図５および図６に示されるように、導出部２３の端部に設けられたシール部材取付部２３２に着脱可能に取り付けられる。シール部材は、シール部材取付部２３２の係合部２３２ａに軸Ｘ方向に係合する被係合部３２を有している。これにより、インナーケーブルＣａがシール部材３に対して摺動したときに、シール部材３がシール部材取付部２３２から離脱することが抑制される。 As described above, the seal member 3 is provided at the end of the lead-out portion 23 on the straight line arrangement portion ST side, which will be described later. Specifically, as shown in FIGS. 5 and 6, the seal member 3 is detachably attached to the seal member attachment portion 232 provided at the end of the lead-out portion 23. The seal member has an engaged portion 32 that engages with the engaging portion 232a of the seal member mounting portion 232 in the axis X direction. As a result, when the inner cable Ca slides with respect to the seal member 3, the seal member 3 is prevented from being detached from the seal member attachment portion 232.
　シール部材３の構造は特に限定されないが、本実施形態では、図５および図６に示されるように、シール部材３は、係合部２３２ａに係合する被係合部３２が設けられた大径部３ａと、大径部３ａと軸Ｘ方向に連続し、貫通孔３１が形成された小径部３ｂとを有している。 The structure of the seal member 3 is not particularly limited, but in the present embodiment, as shown in FIGS. 5 and 6, the seal member 3 is provided with a large engaged portion 32 that engages with the engaging portion 232a. It has a diameter portion 3a, a large diameter portion 3a, and a small diameter portion 3b continuous with the axis X direction and having a through hole 31 formed therein.
　つぎに、基部２１の詳細について説明する。本実施形態では、基部２１には、図５および図６に示されるように、導出部２３と案内部２４との間に、インナーケーブルＣａが直線状に延在可能な直線配索部ＳＴが設けられている。より具体的には、直線配索部ＳＴは、図５および図６に示されるように、導出部２３に取り付けられたシール部材３の案内部側開口３１ｂの開口縁から案内部２４の導入部２４２までの間において、インナーケーブルＣａが直線状に延びている基部２１の所定の領域である。 Next, the details of the base 21 will be described. In the present embodiment, as shown in FIGS. 5 and 6, the base portion 21 has a straight line arrangement portion ST in which the inner cable Ca can extend linearly between the lead-out portion 23 and the guide portion 24. It is provided. More specifically, as shown in FIGS. 5 and 6, the straight line arrangement portion ST is an introduction portion of the guide portion 24 from the opening edge of the guide portion side opening 31b of the seal member 3 attached to the lead-out portion 23. Up to 242, it is a predetermined region of the base 21 in which the inner cable Ca extends linearly.
　直線配索部ＳＴにおいては、インナーケーブルＣａは他部材に案内されておらず、インナーケーブルＣａの外周が他部材と非接触状態で直線状に延びている。本実施形態では、直線配索部ＳＴは空間部ＳＰを有しており、インナーケーブルＣａの径方向外側に所定の距離が確保された空間部ＳＰにおいてインナーケーブルＣａの外周が他部材と非接触状態で直線状に延びている。なお、本実施形態では直線配索部ＳＴの空間部ＳＰは基部２１の上下に開口部Ａ１および第２開口部Ａ２を有しているが、直線配索部ＳＴは、必ずしも上側または下側に開口部を有している必要はない。 In the straight line arrangement portion ST, the inner cable Ca is not guided by other members, and the outer circumference of the inner cable Ca extends linearly in a non-contact state with other members. In the present embodiment, the straight line arrangement portion ST has a space portion SP, and the outer circumference of the inner cable Ca is not in contact with other members in the space portion SP in which a predetermined distance is secured on the radial outer side of the inner cable Ca. It extends linearly in the state. In the present embodiment, the space portion SP of the straight line arrangement portion ST has openings A1 and a second opening A2 above and below the base portion 21, but the straight line arrangement portion ST is not necessarily on the upper side or the lower side. It is not necessary to have an opening.
　直線配索部ＳＴは、導出部２３と案内部２４との間において、インナーケーブルＣａが延びる方向（軸Ｘ方向）と略垂直な方向Ｙ（図６参照）に案内部２４が移動した際に、シール部材３への略垂直な方向Ｙへの負荷を軽減可能な距離として設けられている。「シール部材３への略垂直な方向Ｙへの負荷を軽減可能な距離」は、後述する直線配索部ＳＴの効果を奏することが可能な、直線配索部ＳＴの軸Ｘ方向での所定の距離である。この距離は、シール構造１の取付対象に応じて変更することが可能であり、特に具体的な数値は限定されない。シール構造１の取付対象が自動二輪車である場合、直線配索部ＳＴの軸Ｘ方向での距離は、たとえば２ｍｍ以上、好ましくは５ｍｍ以上とすることができる。また、この距離の上限も特に限定されず、直線配索部ＳＴの軸Ｘ方向での距離は、たとえば１５ｍｍ以下、好ましくは１０ｍｍ以下とすることができる。なお、インナーケーブルＣａが延びる方向と略垂直な方向Ｙは、図５においては上下方向として示しているが、インナーケーブルＣａが延びる方向（軸Ｘ方向）に垂直な方向を成分として含む方向であれば、上下方向に限定されない。たとえば、略垂直な方向Ｙは、図５における紙面奥行方向などであってもよい。 When the guide portion 24 moves between the lead-out portion 23 and the guide portion 24 in the direction Y (see FIG. 6) substantially perpendicular to the direction in which the inner cable Ca extends (axis X direction). , The distance is provided as a distance capable of reducing the load in the direction Y substantially perpendicular to the seal member 3. The "distance that can reduce the load in the substantially vertical direction Y to the seal member 3" is a predetermined distance in the axis X direction of the linear wiring unit ST that can exert the effect of the linear wiring unit ST described later. Is the distance. This distance can be changed according to the mounting target of the seal structure 1, and a specific numerical value is not particularly limited. When the attachment target of the seal structure 1 is a motorcycle, the distance of the straight line arrangement portion ST in the axis X direction can be, for example, 2 mm or more, preferably 5 mm or more. Further, the upper limit of this distance is not particularly limited, and the distance of the straight line arrangement portion ST in the axis X direction can be, for example, 15 mm or less, preferably 10 mm or less. The direction Y substantially perpendicular to the direction in which the inner cable Ca extends is shown as a vertical direction in FIG. 5, but it may be a direction including a direction perpendicular to the direction in which the inner cable Ca extends (axis X direction) as a component. For example, it is not limited to the vertical direction. For example, the substantially vertical direction Y may be the paper depth direction in FIG.
　シール構造１に直線配索部ＳＴが設けられている場合、インナーケーブルＣａからシール部材３へと略垂直な方向Ｙに加わる負荷が軽減されて、シール部材３の変形が抑制される。これにより、シール部材３の変形によってアウターケーシングＣｂ内に水が浸入したり、シール部材３の繰り返しの変形によるシール部材３の寿命が短くなることを抑制することができる。 When the seal structure 1 is provided with the straight line arrangement portion ST, the load applied in the direction Y substantially perpendicular to the inner cable Ca to the seal member 3 is reduced, and the deformation of the seal member 3 is suppressed. As a result, it is possible to prevent water from entering the outer casing Cb due to the deformation of the seal member 3 and shorten the life of the seal member 3 due to repeated deformation of the seal member 3.
　より詳細に説明すると、たとえば、案内部材２とその周囲の部材との間のガタや、取付対象に加わる振動などによって、案内部２４が接続部２２に対して略垂直な方向Ｙで変位するように撓んだりすると、案内部２４が導出部２３（またはシール部材３）に対して略垂直な方向Ｙに移動する場合がある。この場合、インナーケーブルＣａの案内部２４に案内される部位は、案内部２４とともに略垂直な方向Ｙへ移動する（たとえば図８および図９参照。なお、図８および図９は理解を容易にするために変形量を強調している）。この際に、直線配索部ＳＴが設けられていない場合、図８に示されるように、案内部２４がシール部材３に対して略垂直な方向Ｙに移動すると、インナーケーブルＣａがシール部材３側から案内部２４の導入部２４２に入るときに曲がってしまう。この場合、図８に示されるように、シール部材３の案内部側開口３１ｂの開口縁がインナーケーブルＣａが曲がった方向に広がってしまい、インナーケーブルＣａの外周とシール部材３との間に隙間が生じて、水がアウターケーシングＣｂ側に浸入しやすくなる。また、長期間の使用によって、シール部材３の案内部側開口３１ｂの開口縁が繰り返し変形してしまうと、シール部材３がへたってしまい、シール部材３が早期に劣化してしまう。 More specifically, for example, the guide portion 24 is displaced in a direction Y substantially perpendicular to the connection portion 22 due to play between the guide member 2 and the surrounding members, vibration applied to the mounting target, and the like. The guide portion 24 may move in the direction Y substantially perpendicular to the lead-out portion 23 (or the seal member 3). In this case, the portion guided by the guide portion 24 of the inner cable Ca moves in a substantially vertical direction Y together with the guide portion 24 (see, for example, FIGS. 8 and 9. Note that FIGS. 8 and 9 are easy to understand. The amount of deformation is emphasized in order to do this). At this time, when the straight line arrangement portion ST is not provided, as shown in FIG. 8, when the guide portion 24 moves in the direction Y substantially perpendicular to the seal member 3, the inner cable Ca moves to the seal member 3. It bends when entering the introduction unit 242 of the guide unit 24 from the side. In this case, as shown in FIG. 8, the opening edge of the guide portion side opening 31b of the seal member 3 expands in the direction in which the inner cable Ca is bent, and a gap is provided between the outer periphery of the inner cable Ca and the seal member 3. Is generated, and water easily infiltrates into the outer casing Cb side. Further, if the opening edge of the guide portion side opening 31b of the seal member 3 is repeatedly deformed due to long-term use, the seal member 3 is worn out and the seal member 3 is deteriorated at an early stage.
　一方、本実施形態のように直線配索部ＳＴが設けられている場合、案内部２４が図８に示される状態と同じ量で略垂直な方向Ｙに変位したとしても、図９に示されるように、直線配索部ＳＴを有していることにより、図８のようにインナーケーブルＣａが急激に曲がることが抑制される。そのため、シール部材３の案内部側開口３１ｂの開口縁におけるシール部材３の変形量を小さくすることができる。したがって、インナーケーブルＣａの外周とシール部材３との間に隙間が生じることが抑制され、アウターケーシングＣｂ側への水の浸入を抑制することができる。また、取付対象の振動時などにおいて、シール部材３の案内部側開口３１ｂの開口縁の変形量を小さくすることができるため、シール部材３の寿命を延ばすことができる。同様に、案内部材２やシール部材３の製造誤差によって、シール部材３の案内部側開口３１ｂの開口縁と案内部２４の導入部２４２の位置が略垂直な方向Ｙでずれたとしても、直線配索部ＳＴが設けられていることによって、シール部材３の案内部側開口３１ｂの開口縁の変形量を小さくすることができ、シール部材３の寿命を延ばすことができる。また、本実施形態では、直線配索部ＳＴにおいては、インナーケーブルＣａの外周は他の部材に対して非接触であるため、摺動抵抗の増加が抑制される。 On the other hand, when the straight line arrangement portion ST is provided as in the present embodiment, even if the guide portion 24 is displaced in the substantially vertical direction Y by the same amount as the state shown in FIG. 8, it is shown in FIG. As described above, by having the straight line arrangement portion ST, it is suppressed that the inner cable Ca is suddenly bent as shown in FIG. Therefore, the amount of deformation of the seal member 3 at the opening edge of the guide portion side opening 31b of the seal member 3 can be reduced. Therefore, it is possible to suppress the formation of a gap between the outer circumference of the inner cable Ca and the seal member 3, and it is possible to suppress the intrusion of water into the outer casing Cb side. Further, since the amount of deformation of the opening edge of the guide portion side opening 31b of the seal member 3 can be reduced when the object to be attached vibrates, the life of the seal member 3 can be extended. Similarly, even if the opening edge of the guide portion side opening 31b of the seal member 3 and the position of the introduction portion 242 of the guide portion 24 are displaced in a substantially vertical direction Y due to a manufacturing error of the guide member 2 or the seal member 3, a straight line is formed. By providing the wiring portion ST, the amount of deformation of the opening edge of the guide portion side opening 31b of the seal member 3 can be reduced, and the life of the seal member 3 can be extended. Further, in the present embodiment, in the straight line arrangement portion ST, since the outer circumference of the inner cable Ca is not in contact with other members, an increase in sliding resistance is suppressed.
　本実施形態では、直線配索部ＳＴは、シール部材３が着脱可能な空間部ＳＰを有している。直線配索部ＳＴがシール部材３を着脱可能な空間部ＳＰを有していることにより、シール部材３の導出部２３への取り付けが容易となる。シール部材３を導出部２３に取り付ける場合、シール部材３の貫通孔３１の軸と、導出部２３の挿通孔２３１の軸とが軸Ｘ方向に並ぶように、シール部材３を空間部ＳＰに入れる。そして、シール部材３をシール部材取付部２３２に向けて軸Ｘ方向に移動させることによって、シール部材３を導出部２３に容易に取り付けることができる。空間部ＳＰの軸Ｘ方向の長さは、シール部材３を導出部２３に取り付け可能であれば、特に限定されない。たとえば、導出部２３の案内部２４側の先端から、案内部２４の導入部２４２までの軸Ｘ方向の長さが、シール部材３の軸Ｘ方向の長さよりも長い場合、シール部材３の導出部２３への取り付けがより容易になる。また、空間部ＳＰの略垂直な方向Ｙの長さ（開口部Ａ１から第２開口部Ａ２までの長さ）は特に限定されないが、たとえばシール部材３の外径（大径部３ａの外径）よりも長くすることができる。 In the present embodiment, the straight line arrangement portion ST has a space portion SP to which the seal member 3 can be attached and detached. Since the straight line arrangement portion ST has a space portion SP to which the seal member 3 can be attached and detached, the seal member 3 can be easily attached to the lead-out portion 23. When the seal member 3 is attached to the lead-out portion 23, the seal member 3 is inserted into the space portion SP so that the shaft of the through hole 31 of the seal member 3 and the shaft of the insertion hole 231 of the lead-out portion 23 are aligned in the axis X direction. .. Then, by moving the seal member 3 toward the seal member attachment portion 232 in the axis X direction, the seal member 3 can be easily attached to the lead-out portion 23. The length of the space portion SP in the axis X direction is not particularly limited as long as the seal member 3 can be attached to the lead-out portion 23. For example, when the length in the axis X direction from the tip of the lead-out unit 23 on the guide portion 24 side to the introduction portion 242 of the guide portion 24 is longer than the length in the axis X direction of the seal member 3, the seal member 3 is led out. It becomes easier to attach to the portion 23. Further, the length of the space SP in the substantially vertical direction Y (the length from the opening A1 to the second opening A2) is not particularly limited, but for example, the outer diameter of the seal member 3 (the outer diameter of the large diameter portion 3a). ) Can be longer.
　また、本実施形態では、基部２１の空間部ＳＰは、アウターケーシングＣｂの軸Ｘ方向に対して略垂直な方向Ｙに開口部（開口部Ａ１または第２開口部Ａ２）を有し、シール部材３を直線配索部ＳＴに導入可能な開口を形成している。これにより、シール部材３を導出部２３に取り付ける際に、開口部を経由してシール部材３を空間部ＳＰに向かって移動させることができるため、シール部材３を導出部２３に取り付ける際のシール部材３の空間部ＳＰへの導入が容易となる。 Further, in the present embodiment, the space portion SP of the base portion 21 has an opening (opening A1 or second opening A2) in a direction Y substantially perpendicular to the axis X direction of the outer casing Cb, and is a sealing member. 3 is formed in an opening that can be introduced into the straight line arrangement portion ST. As a result, when the seal member 3 is attached to the lead-out portion 23, the seal member 3 can be moved toward the space portion SP via the opening, so that the seal when the seal member 3 is attached to the lead-out portion 23 is sealed. It becomes easy to introduce the member 3 into the space SP.
　また、本実施形態では、基部２１は、開口部Ａ１とは異なる第２開口部Ａ２を有している。この場合、基部２１に開口部Ａ１と第２開口部Ａ２との２つの開口が形成されているので、２方向からシール部材３を指などで挟み込むように把持して、導出部２３に取り付けることができ、さらにシール部材３の取り付けが容易になる。開口部Ａ１と第２開口部Ａ２とが、略垂直な方向Ｙ（上下方向）で互いに対向して形成されている場合、シール部材３を略垂直な方向Ｙ（上下方向）で挟み込むように把持することができ、よりシール部材３の取り付けが容易になる。なお、第２開口部Ａ２が設けられる位置は、開口部Ａ１と対向する位置に限定されず、第２開口部Ａ２は基部２１の側方に形成されていてもよい。 Further, in the present embodiment, the base portion 21 has a second opening A2 different from the opening A1. In this case, since the base portion 21 is formed with two openings, the opening A1 and the second opening A2, the seal member 3 is gripped from two directions so as to be sandwiched between fingers or the like and attached to the lead-out portion 23. Further, the sealing member 3 can be easily attached. When the opening A1 and the second opening A2 are formed so as to face each other in a substantially vertical direction Y (vertical direction), the seal member 3 is gripped so as to be sandwiched in a substantially vertical direction Y (vertical direction). This makes it easier to attach the seal member 3. The position where the second opening A2 is provided is not limited to the position facing the opening A1, and the second opening A2 may be formed on the side of the base 21.
　上述したように、本実施形態では、図６に示されるように、基部２１は、シール部材３と案内部２４との間に空間を形成する空間部ＳＰを有し、空間部ＳＰは、シール部材３と案内部２４との間の水を排出可能な開口部Ａ１を有している。開口部Ａ１の大きさは、シール部材３と案内部２４との間に浸入した水を排出することができる大きさであれば、特に限定されない。 As described above, in the present embodiment, as shown in FIG. 6, the base portion 21 has a space portion SP that forms a space between the seal member 3 and the guide portion 24, and the space portion SP is a seal. It has an opening A1 between the member 3 and the guide portion 24 capable of discharging water. The size of the opening A1 is not particularly limited as long as it can discharge the water that has entered between the seal member 3 and the guide portion 24.
　上述したように、空間部ＳＰが水を排出可能な開口部Ａ１を有している場合、シール部材３と案内部２４との間に水が浸入したとしても開口部Ａ１から水が排出される。そのため、シール部材３の案内部側開口３１ｂの開口縁において水が溜まることが抑制される。たとえば図８のように、シール部材３の案内部側開口３１ｂの開口縁の近傍の領域ＲにおいてインナーケーブルＣａの直下に部材が設けられている場合には、水の逃げ場がなく、溜まった水がインナーケーブルＣａの繰り返しの摺動によって、導出部２３に向かって水が移動しやすくなる。一方、本実施形態では、シール部材３の案内部側開口３１ｂの開口縁において、図６に示されるように、開口部Ａ１によって水の逃げ場が存在する。そのため、シール部材３の案内部側開口３１ｂの開口縁において水が溜まることが抑制され、アウターケーシングＣｂの一端Ｅｂ１に向かって水が浸入することが抑制される。 As described above, when the space SP has an opening A1 capable of discharging water, water is discharged from the opening A1 even if water enters between the seal member 3 and the guide portion 24. .. Therefore, water is prevented from accumulating at the opening edge of the guide portion side opening 31b of the seal member 3. For example, as shown in FIG. 8, when the member is provided directly under the inner cable Ca in the region R near the opening edge of the guide portion side opening 31b of the seal member 3, there is no escape place for water and the accumulated water. However, due to the repeated sliding of the inner cable Ca, water easily moves toward the lead-out portion 23. On the other hand, in the present embodiment, at the opening edge of the guide portion side opening 31b of the seal member 3, as shown in FIG. 6, there is an escape place for water by the opening A1. Therefore, the accumulation of water at the opening edge of the guide portion side opening 31b of the seal member 3 is suppressed, and the infiltration of water toward one end Eb1 of the outer casing Cb is suppressed.
　開口部Ａ１の位置は、シール部材３の案内部側開口３１ｂの開口縁において水が溜まることを抑制できるように開口していれば特に限定されない。本実施形態では、基部２１の開口部Ａ１は、空間部ＳＰに浸入した水が重力によって開口部Ａ１から排出できるように、基部２１の下側に設けられている。このように、開口部Ａ１が重力方向に開口していることによって、基部２１へと浸入した水を円滑に排出することができる。 The position of the opening A1 is not particularly limited as long as it is opened at the opening edge of the guide portion side opening 31b of the seal member 3 so as to prevent water from accumulating. In the present embodiment, the opening A1 of the base 21 is provided below the base 21 so that the water that has entered the space SP can be discharged from the opening A1 by gravity. By opening the opening A1 in the direction of gravity in this way, the water that has entered the base 21 can be smoothly discharged.
　また、開口部Ａ１は、図６に示されるように、基部２１の底面において導出部２３の下方から案内部２４に向って設けられている。このように、開口部Ａ１が、導出部２３の下方から案内部２４まで広く開放した開口として形成されていることにより、水の排出が円滑となり、さらにシール部材３の導出部２３への取り付けも容易となる。本実施形態では、開口部Ａ１は、上述したようにシール部材３を直線配索部ＳＴに導入可能な大きさに形成されており、シール部材３を取り付けやすいうえに、浸入した水の量が多くても容易に排出することができる。 Further, as shown in FIG. 6, the opening A1 is provided on the bottom surface of the base 21 from below the lead-out portion 23 toward the guide portion 24. As described above, since the opening A1 is formed as an opening wide open from the lower side of the lead-out portion 23 to the guide portion 24, water can be discharged smoothly, and the seal member 3 can be attached to the lead-out portion 23. It will be easy. In the present embodiment, the opening A1 is formed in a size that allows the seal member 3 to be introduced into the straight line arrangement portion ST as described above, so that the seal member 3 can be easily attached and the amount of water that has entered is large. At most, it can be easily discharged.
　また、本実施形態では、基部２１の下側に開口部Ａ１が設けられ、基部２１の上側に第２開口部Ａ２が設けられている。これにより、開口部Ａ１および第２開口部Ａ２によって、インナーケーブルＣａが延びている空間部ＳＰに空気の流れが生じる。これによって、開口部Ａ１からの水の排出がさらに促進される。なお、本実施形態では、第２開口部Ａ２は、ハウジングＨによって覆われているため、水分が直接第２開口部Ａ２から浸入することが抑制されている。また、本実施形態では、シール構造１は、上述したように、シール部材３と案内部２４との間に直線配索部ＳＴを有しているので案内部２４側からインナーケーブルＣａを伝う水がシール部材３に到達しにくいため、さらにアウターケーシングＣｂへの水の浸入を抑制することができる。 Further, in the present embodiment, the opening A1 is provided on the lower side of the base 21, and the second opening A2 is provided on the upper side of the base 21. As a result, the opening A1 and the second opening A2 cause an air flow in the space SP where the inner cable Ca extends. This further promotes the drainage of water from the opening A1. In the present embodiment, since the second opening A2 is covered with the housing H, it is suppressed that water directly enters from the second opening A2. Further, in the present embodiment, as described above, the seal structure 1 has the linear wiring portion ST between the seal member 3 and the guide portion 24, so that water transmitted from the guide portion 24 side to the inner cable Ca. Is hard to reach the seal member 3, so that it is possible to further suppress the intrusion of water into the outer casing Cb.
　本実施形態では、案内部材２は、ハウジングＨの内側空間に収容されている。スロットルグリップＧと接続しているハウジングＨは、コントロールケーブルＣが導出される第一開口部と操作部ＯＰ１側の第二開口部とを有している。この第二開口部は、スロットルグリップＧの端部が貫通している。ハウジングＨは、内部に案内部材２を収容することができるように、複数の部材が組み立てられることで構成されている。本実施形態においては、一方の半割状のハウジング部材Ｈａと他方の半割状のハウジング部材Ｈｂとは、コントロールケーブルＣの軸方向に延びる接触面をそれぞれ有している。ハウジングＨは、一方の半ハウジング部材Ｈａの接触面と、他方のハウジング部材Ｈｂの接触面とが接触して接合部を形成し、一方のハウジング部材Ｈａと他方のハウジング部材Ｈｂが組み合わさることで形成されている。ハウジングＨの第一開口部から水分がハウジングＨ内に侵入した場合には、侵入した水分はインナーケーブルＣａに付着する。インナーケーブルＣａに付着した水分がシール部材３によって、アウターケーシングＣｂの内部への侵入を抑制されると、水分は基体２１の空間部ＳＰから開口部Ａ１へと移動する。開口部Ａ１へ移動した水分は、第一開口部、第二開口部やハウジング部材同士の接合部での隙間など、水分の排出が可能な部位よりハウジングＨから排出されることができる。また、開口部Ａ１へ移動した水分は、案内部材２からアウターケーシングＣｂと反対側へと延びたインナーケーブルの一端Ｅａ１の係合部Ｗｂよりも下方に空間が設けられた場合には、その空間に移動することができる。このように、シール構造１は、シール部材３によってアウターケーシングＣｂ内に侵入しようとした水分を忌避しつつ、再び水分がシール部材３に接触することも抑制できる。 In the present embodiment, the guide member 2 is housed in the inner space of the housing H. The housing H connected to the throttle grip G has a first opening from which the control cable C is led out and a second opening on the operation unit OP1 side. The end of the throttle grip G penetrates the second opening. The housing H is configured by assembling a plurality of members so that the guide member 2 can be housed inside. In the present embodiment, one half-split housing member Ha and the other half-split housing member Hb each have a contact surface extending in the axial direction of the control cable C. In the housing H, the contact surface of one half housing member Ha and the contact surface of the other housing member Hb come into contact with each other to form a joint, and the one housing member Ha and the other housing member Hb are combined. It is formed. When moisture enters the housing H from the first opening of the housing H, the invading moisture adheres to the inner cable Ca. When the moisture adhering to the inner cable Ca is suppressed from entering the inside of the outer casing Cb by the sealing member 3, the moisture moves from the space SP of the substrate 21 to the opening A1. The water that has moved to the opening A1 can be discharged from the housing H from a portion where the water can be discharged, such as a gap between the first opening, the second opening, and the joint between the housing members. Further, when a space is provided below the engaging portion Wb of one end Ea1 of the inner cable extending from the guide member 2 to the side opposite to the outer casing Cb, the moisture transferred to the opening A1 is the space. You can move to. In this way, the seal structure 1 can prevent the water from coming into contact with the seal member 3 again while repelling the water that has tried to enter the outer casing Cb by the seal member 3.
