Further, in the present embodiment, the housing 1 regulates the movement of the lock member 4 from the locked state to the unlocked state when the lock member 4 is in the locked state (see FIG. 3B). The unit 17 is further provided.
　ロック部材４は、ロッド２の外周と係合して、ロッド２を軸Ｘ方向の所定の位置でハウジング１に対してロックする。ロック部材４は、本実施形態では、ハウジング１に、軸Ｘ方向に略垂直な方向に移動可能に取り付けられている。ロック部材４は、ロッド２の外周と係合せず、ロッド２の軸Ｘ方向の移動を可能にするアンロック位置（図３（Ａ）参照）と、ロッド２の外周と係合して、ロッド２の軸Ｘ方向の移動を規制するロック位置（図３（Ｂ）参照）との間を移動する。ロック部材４の形状および構造は、ロッド２と軸Ｘ方向で係合して、ロッド２の軸Ｘ方向への移動を規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、ロック部材４は、図１に示されるように、互いに対向する一対の側壁４１、４２と、一対の側壁４１、４２を繋ぐ連結部４３とを備え、軸Ｘ方向に垂直な断面が略Ｕ字形状とされている。一対の側壁４１、４２には、ロッド２の外周と対向する部位に、係合部２２と係合する被係合部４４を有している。被係合部４４は、本実施形態では、軸Ｘ方向に沿って溝と突起とが交互に並んだ凹凸構造を有している。被係合部４４は、ロック部材４がロック位置に移動したときに、ロッド２の係合部２２と軸Ｘ方向に係合して、ロッド２のハウジング１に対する軸Ｘ方向の移動を規制する。 The lock member 4 engages with the outer circumference of the rod 2 and locks the rod 2 with respect to the housing 1 at a predetermined position in the axis X direction.

　本実施形態では、コントロールケーブルＣの長さを調節する場合、ハウジング１に対するロッド２の軸Ｘ方向の位置を調節したのち、ロック部材４をロッド２の外周に向けて押圧して、ロック部材４をロック位置に移動させる。ロック部材４がロック位置に移動すると、ロッド２の外周にロック部材４が係合して、ロッド２の軸Ｘ方向の移動が規制され、ロッド２のハウジング１に対する位置が保持され、コントロールケーブルＣの長さが調節される。ロック部材４をロック位置に移動させた後、図３（Ｂ）に示されるように、規制部１７を軸Ｘ方向にスライドさせて、ロック部材４がロック位置からアンロック位置へ移動することが規制される。これにより、ロッド２の軸Ｘ方向での移動がさらに規制される。 In the present embodiment, when adjusting the length of the control cable C, after adjusting the position of the rod 2 with respect to the housing 1 in the axis X direction, the lock member 4 is pressed toward the outer circumference of the rod 2 to lock the lock member 4. To the locked position. When the lock member 4 moves to the lock position, the lock member 4 engages with the outer circumference of the rod 2, the movement of the rod 2 in the axis X direction is restricted, the position of the rod 2 with respect to the housing 1 is maintained, and the control cable C The length of is adjusted. After moving the lock member 4 to the lock position, as shown in FIG. 3 (B), the restricting portion 17 can be slid in the axis X direction to move the lock member 4 from the lock position to the unlock position. Be regulated. As a result, the movement of the rod 2 in the axis X direction is further restricted.
　次に、ロッド２の先端部２１について説明する。ロッド２の先端部２１は、取付対象に設けられた孔Ｈに挿通される、ロッド２の先端側の所定の部位をいう。本実施形態では、ロッド２の先端部２１は、ハウジング１に設けられた孔Ｈに挿通されて嵌合し、孔Ｈに対して、軸Ｘ方向で挿入方向とは反対方向となる離脱方向へと移動することが規制される。 Next, the tip portion 21 of the rod 2 will be described. The tip portion 21 of the rod 2 refers to a predetermined portion on the tip end side of the rod 2 that is inserted into a hole H provided in the mounting target. In the present embodiment, the tip portion 21 of the rod 2 is inserted into and fitted into the hole H provided in the housing 1, and the rod 2 is fitted in the hole H in the detaching direction which is opposite to the insertion direction in the axis X direction. It is regulated to move with.
　ロッド２の先端部２１は、図２、図４および図５に示されるように、孔Ｈの内径よりも大径の張出部２１１と、ロッド２の軸Ｘ方向の端縁となる先端２１２と、張出部２１１と先端２１２とを軸Ｘ方向に繋ぐテーパー部２１３と、張出部２１１の基端側に軸Ｘ回り方向に設けられた溝部２１４とを有している。また、本実施形態では、ロッド２の先端部２１は、先端２１２から軸Ｘ方向に延びる空間部２１５を有している。空間部２１５は、ロッド２の先端部２１を、軸Ｘに垂直な断面において、径方向に２つの部分に分離、または軸Ｘ周り方向に複数の部分に分離する。ロッド２の先端部２１の全体形状は特に限定されないが、本実施形態では、先端２１２に向かって細くなる、中空の略円錐台状に形成されている。より具体的には、本実施形態では、ロッド２の先端部２１は、略円錐台状のテーパー部２１３の基端側に略円柱状の張出部２１１が軸Ｘ方向に連なっており、先端部２１の側面に軸Ｘを挟むように２つのスリット状の空間部２１５が形成されている。 As shown in FIGS. 2, 4 and 5, the tip 21 of the rod 2 has an overhanging portion 211 having a diameter larger than the inner diameter of the hole H and a tip 212 which is an end edge of the rod 2 in the axis X direction. It has a tapered portion 213 that connects the overhanging portion 211 and the tip 212 in the axis X direction, and a groove portion 214 provided on the base end side of the overhanging portion 211 in the axial X direction. Further, in the present embodiment, the tip portion 21 of the rod 2 has a space portion 215 extending from the tip 212 in the axis X direction. The space portion 215 separates the tip portion 21 of the rod 2 into two portions in the radial direction or a plurality of portions in the direction around the axis X in a cross section perpendicular to the axis X. The overall shape of the tip 21 of the rod 2 is not particularly limited, but in the present embodiment, it is formed in a hollow substantially truncated cone shape that narrows toward the tip 212. More specifically, in the present embodiment, the tip portion 21 of the rod 2 has a substantially cylindrical overhanging portion 211 connected to the base end side of the substantially truncated cone-shaped tapered portion 213 in the axis X direction, and the tip end thereof. Two slit-shaped space portions 215 are formed on the side surface of the portion 21 so as to sandwich the shaft X.
　ロッド２の先端２１２は、ロッド２の先端部２１のうち、孔Ｈに挿入される挿入端である。本実施形態では、先端２１２は、孔Ｈの内径よりも径が小さくなるように構成されている。この場合、ロッド２の先端部２１を孔Ｈに導入する際に、孔Ｈの開口縁にテーパー部２１３が当接し（図９参照）、先端部２１を孔Ｈに貫通させることが容易となる。 The tip 212 of the rod 2 is an insertion end inserted into the hole H of the tip 21 of the rod 2. In the present embodiment, the tip 212 is configured to have a diameter smaller than the inner diameter of the hole H. In this case, when the tip portion 21 of the rod 2 is introduced into the hole H, the tapered portion 213 comes into contact with the opening edge of the hole H (see FIG. 9), and the tip portion 21 can easily penetrate the hole H. ..
　テーパー部２１３は、軸Ｘ方向で先端２１２と張出部２１１との間に設けられている。テーパー部２１３は孔Ｈに挿入される際に、孔Ｈの開口縁と当接し、ロッド２の先端部２１が孔Ｈに挿入される際に、孔Ｈの開口縁に対して摺動する。テーパー部２１３の先端側の外径は、孔Ｈの内径よりも小さく、テーパー部２１３の基端側の外径は、孔Ｈの内径よりも大きくなっている。本実施形態では、ロッド２の先端部２１が孔Ｈに挿入される際に、テーパー部２１３の外周は孔Ｈの開口縁から径方向内側に向かう力を受け、先端部２１に設けられた空間部２１５が狭くなるように先端部２１が変形する。これにより、テーパー部２１３および張出部２１１の外径が小さくなり、ロッド２の先端部２１を孔Ｈに挿入しやすくなっている。 The tapered portion 213 is provided between the tip 212 and the overhanging portion 211 in the axis X direction. When the tapered portion 213 is inserted into the hole H, it comes into contact with the opening edge of the hole H, and when the tip portion 21 of the rod 2 is inserted into the hole H, it slides with respect to the opening edge of the hole H. The outer diameter of the tapered portion 213 on the tip end side is smaller than the inner diameter of the hole H, and the outer diameter of the tapered portion 213 on the proximal end side is larger than the inner diameter of the hole H. In the present embodiment, when the tip portion 21 of the rod 2 is inserted into the hole H, the outer periphery of the tapered portion 213 receives a force radially inward from the opening edge of the hole H, and a space provided in the tip portion 21. The tip portion 21 is deformed so that the portion 215 becomes narrower. As a result, the outer diameters of the tapered portion 213 and the overhanging portion 211 are reduced, and the tip portion 21 of the rod 2 can be easily inserted into the hole H.
　溝部２１４は、張出部２１１の基端側に軸Ｘ周り方向に設けられた溝状の部位である。溝部２１４は、張出部２１１よりも外径が小さくなるように構成されている。本実施形態では、溝部２１４は、軸Ｘ方向で張出部２１１と係合部２２との間に設けられ、張出部２１１および係合部２２に対して径方向内側に凹んだ環状の凹部となっている。本実施形態では、溝部２１４は、張出部２１１が孔Ｈに入るときに、溝部２１４の基端側を支点として溝部２１４から先端２１２までの部位が軸Ｘに向かって近付くように撓むように構成されている（図１０参照）。本実施形態では、溝部２１４の外径は張出部２１１の外径よりも小さく、空間部２１５がロッド２の先端２１２から溝部２１４の基端側まで延びていることにより、溝部２１４を支点として先端部２１が撓みやすくなっている。 The groove portion 214 is a groove-shaped portion provided on the base end side of the overhanging portion 211 in the direction around the axis X. The groove portion 214 is configured to have an outer diameter smaller than that of the overhanging portion 211. In the present embodiment, the groove portion 214 is provided between the overhanging portion 211 and the engaging portion 22 in the axis X direction, and is an annular recess that is radially inwardly recessed with respect to the overhanging portion 211 and the engaging portion 22. It has become. In the present embodiment, when the overhanging portion 211 enters the hole H, the groove portion 214 is configured to bend so that the portion from the groove portion 214 to the tip end 212 approaches the axis X with the base end side of the groove portion 214 as a fulcrum. (See FIG. 10). In the present embodiment, the outer diameter of the groove portion 214 is smaller than the outer diameter of the overhanging portion 211, and the space portion 215 extends from the tip end 212 of the rod 2 to the base end side of the groove portion 214, so that the groove portion 214 is used as a fulcrum. The tip portion 21 is easily bent.
　張出部２１１は、孔Ｈに挿通された後、孔Ｈの周縁部と軸Ｘ方向に係合して、取付対象からロッド２の先端部２１が離脱することを抑制する（図１１参照）。本実施形態では、張出部２１１の外径は、孔Ｈに挿通された後の状態で、孔Ｈの内径よりも大きい。張出部２１１は、図５に示されるように、軸Ｘ方向に略垂直に延び、係合面１４ａと軸Ｘ方向に係合する被係合面２１１ａを有している。この張出部２１１の被係合面２１１ａが、図１１に示されるように、取付対象（壁部１４）の係合面１４ａと軸Ｘ方向で係合することによって、ロッド２がハウジング１から軸Ｘ方向に離脱することが抑制される。 After being inserted into the hole H, the overhanging portion 211 engages with the peripheral edge portion of the hole H in the axial X direction to prevent the tip portion 21 of the rod 2 from being detached from the attachment target (see FIG. 11). .. In the present embodiment, the outer diameter of the overhanging portion 211 is larger than the inner diameter of the hole H in the state after being inserted into the hole H. As shown in FIG. 5, the overhanging portion 211 has an engaged surface 211a that extends substantially perpendicularly to the axis X direction and engages with the engaging surface 14a in the axis X direction. As shown in FIG. 11, the engaged surface 211a of the overhanging portion 211 engages with the engaging surface 14a of the mounting target (wall portion 14) in the axis X direction, so that the rod 2 is displaced from the housing 1. Departure in the X-axis direction is suppressed.
　張出部２１１は、図５に示されるように、外周よりも径方向内側に、溝部２１４から先端方向に凹んだ凹部２１１ｂを有している。凹部２１１ｂは、後述するように、ロッド２の先端部２１が孔Ｈに挿入される際に、凹部２１１ｂの内側の空間が径方向で狭くなるように変形する。これにより、ロッド２の先端部２１が孔Ｈに挿入されるときに、張出部２１１の外径が小さくなるように先端部２１が径方向内側に変形しやすくなり、先端部２１の挿入時に先端部２１が破損することが抑制される。 As shown in FIG. 5, the overhanging portion 211 has a recess 211b recessed in the tip direction from the groove portion 214 on the inner side in the radial direction with respect to the outer circumference. As will be described later, the recess 211b is deformed so that the space inside the recess 211b becomes narrower in the radial direction when the tip 21 of the rod 2 is inserted into the hole H. As a result, when the tip portion 21 of the rod 2 is inserted into the hole H, the tip portion 21 is easily deformed inward in the radial direction so that the outer diameter of the overhanging portion 211 becomes smaller, and when the tip portion 21 is inserted. Damage to the tip 21 is suppressed.
　凹部２１１ｂは、本実施形態では、図５に示されるように、張出部２１１の被係合面２１１ａに対して、軸Ｘ方向で先端側に凹むように形成されている。凹部２１１ｂは、上述したように、張出部２１１の外周に対して径方向で内側の位置に設けられていれば、凹部２１１ｂの径方向での位置は特に限定されないが、本実施形態では、溝部２１４と張出部２１１との境界領域に設けられている。より具体的には、凹部２１１ｂは、溝部２１４の外周の延長線上に軸Ｘ方向に延びている。 In the present embodiment, the recess 211b is formed so as to be recessed toward the tip end side in the axis X direction with respect to the engaged surface 211a of the overhanging portion 211, as shown in FIG. As described above, the concave portion 211b is not particularly limited in the radial position as long as it is provided at the inner position in the radial direction with respect to the outer circumference of the overhanging portion 211. However, in the present embodiment, the concave portion 211b is not particularly limited. It is provided in the boundary region between the groove portion 214 and the overhanging portion 211. More specifically, the recess 211b extends in the axis X direction on an extension of the outer circumference of the groove 214.
　凹部２１１ｂは、図５に示されるように、先端部２１を軸Ｘ方向に沿って切断した断面において、略Ｕ字状、具体的には略半円形状に形成されている。しかし、凹部２１１ｂの断面形状は、先端部２１の孔Ｈへの挿入の際に、凹部２１１ｂの内側の空間が径方向で狭くなるように変形可能な形状であれば、特に限定されない。例えば、凹部２１１ｂの断面形状は、略半円形状の他、略半楕円形状、略三角形状、略矩形状、くさび状、スリット状など、他の形状であってもよい。 As shown in FIG. 5, the recess 211b is formed in a substantially U-shape, specifically, a substantially semicircular shape in a cross section obtained by cutting the tip portion 21 along the axis X direction. However, the cross-sectional shape of the recess 211b is not particularly limited as long as it can be deformed so that the space inside the recess 211b becomes narrower in the radial direction when the tip portion 21 is inserted into the hole H. For example, the cross-sectional shape of the recess 211b may be a substantially semicircular shape, a substantially semi-elliptical shape, a substantially triangular shape, a substantially rectangular shape, a wedge shape, a slit shape, or the like.
　本実施形態では、凹部２１１ｂは、図７に示されるように、軸Ｘ方向に見たときに、被係合面２１１ａのうち溝部２１４との境界領域に沿って略環状に延びている。この場合、張出部２１１が軸Ｘ周り方向のほぼ全方向で撓みやすくなる。したがって、先端部２１を孔Ｈに挿入する際に、張出部２１１の変形が容易となり、先端部２１の破損がより抑制される。なお、「略環状」とは、凹部２１１ｂが軸Ｘ周り方向で連続して完全に環状になっている状態の他、凹部２１１ｂが軸Ｘ周り方向で部分的に途切れている状態も含む。 In the present embodiment, as shown in FIG. 7, the recess 211b extends substantially in an annular shape along the boundary region of the engaged surface 211a with the groove 214 when viewed in the axis X direction. In this case, the overhanging portion 211 tends to bend in almost all directions around the axis X. Therefore, when the tip portion 21 is inserted into the hole H, the overhanging portion 211 is easily deformed, and the damage of the tip portion 21 is further suppressed. The "substantially annular" includes a state in which the recess 211b is continuously and completely annular in the direction around the axis X, and a state in which the recess 211b is partially interrupted in the direction around the axis X.
　凹部２１１ｂの径方向の幅（図５および図６に示される、凹部２１１ｂの径方向内側の縁部Ｅ１と径方向外側の縁部Ｅ２との間の間隔Ｌ１）は、ロッド２の先端部２１の材料等に応じて適宜変更が可能であり、特に限定されない。凹部２１１ｂの径方向内側の縁部Ｅ１と径方向外側の縁部Ｅ２との間の間隔Ｌ１は、例えば、溝部２１４の外周から張出部２１１が径方向に張り出した張出幅Ｌ２（図５参照）の３０～６０％であることが好ましい。また、凹部２１１ｂの軸Ｘ方向の深さＬ３は、ロッド２の先端部２１の材料等に応じて適宜変更が可能であり、特に限定されないが、例えば、張出部２１１の被係合面２１１ａから先端２１２までの軸方向長さＬ４の２０～４０％であることが好ましい。 The radial width of the recess 211b (the distance L1 between the radially inner edge E1 and the radially outer edge E2 of the recess 211b, shown in FIGS. 5 and 6) is the tip 21 of the rod 2. It can be changed as appropriate according to the material of the above, and is not particularly limited. The distance L1 between the radial inner edge E1 and the radial outer edge E2 of the recess 211b is, for example, the overhang width L2 (FIG. 5) in which the overhanging portion 211 protrudes radially from the outer periphery of the groove portion 214. It is preferably 30 to 60% of (see). Further, the depth L3 of the recess 211b in the axis X direction can be appropriately changed according to the material of the tip 21 of the rod 2, and is not particularly limited. For example, the engaged surface 211a of the overhanging portion 211a. It is preferably 20 to 40% of the axial length L4 from to the tip 212.
　上述したように、張出部２１１が外周よりも径方向内側に、溝部２１４から先端方向に凹んだ凹部２１１ｂを有していることにより、ロッド２の先端部２１を孔Ｈに挿入する際に、凹部２１１ｂの内側の空間が径方向で狭くなるように変形する。より具体的には、図６に示されるように、凹部２１１ｂの径方向内側の縁部Ｅ１と径方向外側の縁部Ｅ２との間の間隔Ｌ１が、先端部２１の孔Ｈへの挿入時に、張出部２１１が孔Ｈの開口縁から径方向内側に力を受けることによって狭くなる（図６の狭くなった間隔Ｌ５参照）。これにより、張出部２１１の外径が小さくなり、ロッド２の先端部２１を孔Ｈに挿入することが容易になるとともに、凹部２１１ｂが無い場合の孔Ｈへの嵌合時と比較して、張出部２１１の外周や溝部２１４など、ロッド２の先端部２１に加わる力を低減させることができ、ロッド２の先端部２１の破損を抑制することができる。 As described above, when the tip portion 21 of the rod 2 is inserted into the hole H, the overhanging portion 211 has a recess 211b recessed in the tip direction from the groove portion 214 on the inner side in the radial direction with respect to the outer circumference. , The space inside the recess 211b is deformed so as to be narrowed in the radial direction. More specifically, as shown in FIG. 6, the distance L1 between the radial inner edge E1 and the radial outer edge E2 of the recess 211b is set when the tip 21 is inserted into the hole H. , The overhanging portion 211 is narrowed by receiving a force radially inward from the opening edge of the hole H (see the narrowed interval L5 in FIG. 6). As a result, the outer diameter of the overhanging portion 211 becomes smaller, the tip portion 21 of the rod 2 can be easily inserted into the hole H, and the fitting into the hole H when there is no recess 211b is compared with the case where the rod 2 is fitted into the hole H. It is possible to reduce the force applied to the tip portion 21 of the rod 2 such as the outer circumference of the overhanging portion 211 and the groove portion 214, and it is possible to suppress damage to the tip portion 21 of the rod 2.
　また、本実施形態では、先端部２１は、図８～図１１に示されるように、先端２１２から軸Ｘ方向に延びる空間部２１５を有している。この場合、先端部２１の孔Ｈへの挿入の際に、先端部２１は、空間部２１５の隙間が径方向で狭くなるように径方向内側に撓むと共に、凹部２１１ｂの径方向の間隔Ｌ１が狭くなる（図６および図１０参照）。したがって、空間部２１５による先端部２１の撓みと、凹部２１１ｂの変形との両方の変形を伴って、先端部２１が孔Ｈに挿入される。したがって、空間部２１５の変形だけの場合、または凹部２１１ｂの変形だけの場合と比較して、それぞれの変形量を小さくすることができる。そのため、先端部２１の各部位（例えば、溝部２１４の基端側や張出部２１１の外周など）に加わる負荷が低減され、より先端部２１の破損が抑制される。 Further, in the present embodiment, the tip portion 21 has a space portion 215 extending from the tip 212 in the axis X direction as shown in FIGS. 8 to 11. In this case, when the tip portion 21 is inserted into the hole H, the tip portion 21 bends inward in the radial direction so that the gap of the space portion 215 becomes narrow in the radial direction, and the distance L1 in the radial direction of the recess 211b is formed. Is narrowed (see FIGS. 6 and 10). Therefore, the tip portion 21 is inserted into the hole H with both deformation of the tip portion 21 due to the space portion 215 and deformation of the recess 211b. Therefore, the amount of deformation of each can be reduced as compared with the case of only the deformation of the space portion 215 or the case of only the deformation of the recess 211b. Therefore, the load applied to each portion of the tip portion 21 (for example, the proximal end side of the groove portion 214 or the outer circumference of the overhanging portion 211) is reduced, and damage to the tip portion 21 is further suppressed.
　つぎに、図８～図１１を用いて、ロッド２を取付対象に取り付ける取付動作の一例を説明する。 Next, an example of the mounting operation for mounting the rod 2 to the mounting target will be described with reference to FIGS. 8 to 11.
　図８に示されるように、ロッド２の先端部２１を孔Ｈに向かって軸Ｘ方向に移動させてロッド２の先端２１２を孔Ｈに挿入する。ロッド２の先端２１２が孔Ｈに入ると、ロッド２の先端部２１のテーパー部２１３に孔Ｈの開口縁が当接する（図９参照）。その状態でロッド２を軸Ｘ方向に押し込むと、孔Ｈの開口縁からロッド２のテーパー部２１３に対して径方向内側に反力が加わる。これにより、凹部２１１ｂの径方向の間隔Ｌ１が狭くなるとともに、空間部２１５の径方向の間隔が狭くなるように先端部２１が変形する（図１０参照）。このとき、ロッド２のテーパー部２１３と孔Ｈの開口縁とが摺動しながら、ロッド２が軸Ｘ方向に移動する。凹部２１１ｂの径方向の間隔Ｌ１および空間部２１５の径方向の間隔が狭くなるように先端部２１が変形することによって、張出部２１１の外径が孔Ｈの内径以下となり、ロッド２の先端部２１が孔Ｈに挿入される。このとき、凹部２１１ｂが変形することによって、凹部２１１ｂが無い場合の孔Ｈへの嵌合時と比較して、張出部２１１の外周や溝部２１４など、ロッド２の先端部２１に加わる力を低減させることができ、ロッド２の先端部２１の破損を抑制することができる。また、本実施形態では、空間部２１５による先端部２１の撓みと、凹部２１１ｂの変形との両方の変形を伴って、先端部２１が孔Ｈに挿入される。したがって、空間部２１５の変形だけの場合、または凹部２１１ｂの変形だけの場合と比較して、それぞれの変形量を小さくすることができる。これにより、先端部２１の孔Ｈへの圧入嵌合時に、先端部２１の変形の支点となる溝部２１４の基端側が先端部２１の過度の変形によって割れることや、張出部２１１の外周が割れること、欠けること、または変形することが抑制される。 As shown in FIG. 8, the tip 21 of the rod 2 is moved toward the hole H in the axis X direction, and the tip 212 of the rod 2 is inserted into the hole H. When the tip 212 of the rod 2 enters the hole H, the opening edge of the hole H comes into contact with the tapered portion 213 of the tip 21 of the rod 2 (see FIG. 9). When the rod 2 is pushed in the axis X direction in this state, a reaction force is applied radially inward to the tapered portion 213 of the rod 2 from the opening edge of the hole H. As a result, the radial distance L1 of the recess 211b is narrowed, and the tip portion 21 is deformed so that the radial space of the space portion 215 is narrowed (see FIG. 10). At this time, the rod 2 moves in the axis X direction while the tapered portion 213 of the rod 2 and the opening edge of the hole H slide. By deforming the tip portion 21 so that the radial spacing L1 of the recess 211b and the radial spacing of the space portion 215 become narrower, the outer diameter of the overhanging portion 211 becomes equal to or less than the inner diameter of the hole H, and the tip of the rod 2 The portion 21 is inserted into the hole H. At this time, due to the deformation of the recess 211b, a force applied to the tip portion 21 of the rod 2 such as the outer circumference of the overhanging portion 211 and the groove portion 214 is applied as compared with the case of fitting into the hole H when the recess 211b is not present. It can be reduced and damage to the tip 21 of the rod 2 can be suppressed. Further, in the present embodiment, the tip portion 21 is inserted into the hole H with both deformation of the tip portion 21 due to the space portion 215 and deformation of the recess 211b. Therefore, the amount of deformation of each can be reduced as compared with the case of only the deformation of the space portion 215 or the case of only the deformation of the recess 211b. As a result, when the tip portion 21 is press-fitted into the hole H, the base end side of the groove portion 214, which is the fulcrum of the deformation of the tip portion 21, is cracked due to the excessive deformation of the tip portion 21, and the outer circumference of the overhanging portion 211 is Cracking, chipping, or deformation is suppressed.
　図１０に示される状態からさらにロッド２を軸Ｘ方向に挿入すると、張出部２１１が孔Ｈから出て、凹部２１１ｂの径方向の間隔が広がるとともに、空間部２１５の径方向の間隔が広がって、張出部２１１の外径は孔Ｈの内径よりも大きい状態に戻る。これにより、張出部２１１の被係合面２１１ａが、孔Ｈの周縁部の係合面１４ａと係合可能な状態となり、ロッド２のハウジング１からの離脱が抑制される。 When the rod 2 is further inserted in the axis X direction from the state shown in FIG. 10, the overhanging portion 211 comes out from the hole H, the radial spacing of the recess 211b is widened, and the radial spacing of the space portion 215 is widened. Therefore, the outer diameter of the overhanging portion 211 returns to a state larger than the inner diameter of the hole H. As a result, the engaged surface 211a of the overhanging portion 211 becomes engaged with the engaging surface 14a of the peripheral portion of the hole H, and the rod 2 is suppressed from being detached from the housing 1.
　なお、コントロールケーブルＣの長さ調節装置Ｍは、変形例として、図１２および図１３に示されるように、ハウジング１に設けられ、ロッド２を軸Ｘ方向に付勢する付勢部材５と、ロッド２の先端部２１に嵌合する嵌合部材ＥＮとを備えていてもよい。付勢部材５および嵌合部材ＥＮ以外の構成は、図１～図１１に示される実施形態と同様とすることができるため、説明は省略する。なお、付勢部材５は、本実施形態では、軸Ｘ方向に伸縮するコイルバネである。本実施形態では、付勢部材５の一端５ａは、ハウジング１に取り付けられ、付勢部材５の他端５ｂは嵌合部材ＥＮに取り付けられている。図１２および図１３に示される変形例の場合、付勢部材５によって、ロッド２が軸Ｘ方向で一方の方向に付勢されており、ハウジング１の取付部１３を被操作部に取り付けた際に、付勢部材５の付勢力によってロッド２が軸Ｘ方向で一方の方向に引っ張られ（または押され）、ロッド２およびケーブル３は半自動的に緩みのない状態となる。その状態でロック部材４によってロッド２を固定することができる。そのため、ロック部材４でロッド２をロックする前にロッド２を手動で位置調節する必要がなく、コントロールケーブルＣの長さ調節や、コントロールケーブルＣの被操作部への組み付け作業が容易になる。 As a modification, the length adjusting device M of the control cable C includes an urging member 5 provided in the housing 1 and urging the rod 2 in the axis X direction, as shown in FIGS. 12 and 13. A fitting member EN that fits into the tip 21 of the rod 2 may be provided. Since the configurations other than the urging member 5 and the fitting member EN can be the same as those of the embodiments shown in FIGS. 1 to 11, the description thereof will be omitted. In the present embodiment, the urging member 5 is a coil spring that expands and contracts in the axis X direction. In the present embodiment, one end 5a of the urging member 5 is attached to the housing 1, and the other end 5b of the urging member 5 is attached to the fitting member EN. In the case of the modification shown in FIGS. 12 and 13, when the rod 2 is urged in one direction in the axis X direction by the urging member 5, and the mounting portion 13 of the housing 1 is mounted on the operated portion. In addition, the rod 2 is pulled (or pushed) in one direction in the axis X direction by the urging force of the urging member 5, and the rod 2 and the cable 3 are semi-automatically put into a tight state. In that state, the rod 2 can be fixed by the lock member 4. Therefore, it is not necessary to manually adjust the position of the rod 2 before locking the rod 2 with the lock member 4, and it becomes easy to adjust the length of the control cable C and to assemble the control cable C to the operated portion.
　嵌合部材ＥＮは、変形例において、付勢部材５の他端５ｂを支持するバネ座として機能する。嵌合部材ＥＮは、図１２に示されるように、環状に形成され、中心に嵌合孔Ｈ３を有している。図１２および図１３に示される変形例においては、取付対象は嵌合部材ＥＮであり、取付対象の孔は、嵌合部材ＥＮに設けられた嵌合孔Ｈ３である。なお、嵌合部材ＥＮの嵌合孔Ｈ３にロッド２の先端部２１を取り付ける場合、ロッド２の先端部２１に付勢部材５を通した後、嵌合部材ＥＮの孔Ｈ３に先端部２１が嵌合することにより、組み付けが完了する。具体的には、嵌合部材ＥＮの嵌合孔Ｈ３に向けて、図８～図１１に示された組み付け方と同様の方法で、先端部２１を嵌合部材ＥＮに対して移動させることによって、先端部２１を嵌合部材ＥＮの嵌合孔Ｈ３に挿通することができ、図１２および図１３に示される変形例においても、図１～図１１に示される実施形態と同様の効果を得ることができる。 The fitting member EN functions as a spring seat that supports the other end 5b of the urging member 5 in the modified example. As shown in FIG. 12, the fitting member EN is formed in an annular shape and has a fitting hole H3 at the center. In the modified examples shown in FIGS. 12 and 13, the mounting target is the fitting member EN, and the mounting target hole is the fitting hole H3 provided in the fitting member EN. When the tip 21 of the rod 2 is attached to the fitting hole H3 of the fitting member EN, the tip 21 is placed in the hole H3 of the fitting member EN after the urging member 5 is passed through the tip 21 of the rod 2. By fitting, the assembly is completed. Specifically, by moving the tip portion 21 with respect to the fitting member EN toward the fitting hole H3 of the fitting member EN in the same manner as the assembling method shown in FIGS. 8 to 11. , The tip portion 21 can be inserted into the fitting hole H3 of the fitting member EN, and the same effect as that of the embodiment shown in FIGS. 1 to 11 can be obtained in the modified examples shown in FIGS. 12 and 13. be able to.
