Description

本願は、自動車等に装備される線状部材（例えば、ワイヤハーネス、ケーブル（アクセルケーブル、トランスミッションケーブル等））の配索経路を規制するクランプ装置に関する。   The present application relates to a clamp device that regulates a routing route of a linear member (for example, a wire harness, a cable (accelerator cable, transmission cable, etc.)) installed in an automobile or the like.

この種のクランプ装置としては、曲折した１本の金属線によって線状部材を保持することで、線状部材の配索経路を規制するものがある（例えば、特許文献１）。特許文献１のクランプ装置では、１本の金属線にＵ字状に曲折された保持部が複数形成されている。線状部材は、複数の保持部のそれぞれに挿し込まれ、複数の保持部でそれぞれ保持される。これによって、線状部材の配索経路が規制される。   As this type of clamping device, there is a device that regulates a wiring path of a linear member by holding the linear member with one bent metal wire (for example, Patent Document 1). In the clamp device of Patent Document 1, a plurality of holding portions bent in a U-shape are formed on one metal wire. The linear member is inserted into each of the plurality of holding units and is held by the plurality of holding units. Thereby, the routing route of the linear member is regulated.

実公昭６３−２４２４６号公報Japanese Utility Model Publication No. 63-24246

自動車等に装備される線状部材には、種々の外力が作用する。例えば、排気管に設置されるセンサのワイヤハーネスには排気管の振動等が作用し、あるいは、エンジンルーム内に配置されるケーブルにはエンジンの振動等が作用する。特許文献１のクランプ装置では、隣り合う保持部の間に直線状の制振部を形成することで、線状部材に作用する振動が抑えられるようになっている。しかしながら、このクランプ装置では、各保持部への線状部材の挿し込み方向が同一のため、挿し込み方向と逆向きに大きな力が線状部材に作用すると、線状部材が保持部から外れてしまうという問題があった。   Various external forces act on the linear members equipped in automobiles and the like. For example, the vibration of the exhaust pipe acts on the wire harness of the sensor installed in the exhaust pipe, or the vibration of the engine acts on the cable arranged in the engine room. In the clamp device disclosed in Patent Document 1, the vibration acting on the linear member is suppressed by forming a linear damping portion between adjacent holding portions. However, in this clamping device, since the insertion direction of the linear member to each holding portion is the same, if a large force acts on the linear member in the direction opposite to the insertion direction, the linear member is detached from the holding portion. There was a problem that.

本願は、上記の実情に鑑みてなされたものであって、線状部材の外れを好適に防止することができるクランプ装置を提供することを目的とする。   The present application has been made in view of the above circumstances, and an object thereof is to provide a clamping device that can suitably prevent the linear member from coming off.

本願のクランプ装置は、曲折した１本の金属線によって線状部材の配索経路を規制する。このクランプ装置では、１本の金属線は、線状部材を保持する第１保持部と、第１保持部とは異なる位置で線状部材を保持する第２保持部を少なくとも有している。第１保持部は、１本の金属線をＵ字状に曲折することで形成され、第２保持部は、１本の金属線をＵ字状に曲折することで形成されている。そして、Ｕ字状の第１保持部への線状部材の挿し込み方向が、Ｕ字状の第２保持部への線状部材の挿し込み方向と相違している。   The clamping device of the present application regulates the wiring path of the linear member by one bent metal wire. In this clamping device, one metal wire has at least a first holding part that holds the linear member and a second holding part that holds the linear member at a position different from the first holding part. The first holding portion is formed by bending one metal wire into a U shape, and the second holding portion is formed by bending one metal wire into a U shape. And the insertion direction of the linear member to the U-shaped first holding part is different from the insertion direction of the linear member to the U-shaped second holding part.

このクランプ装置では、第１保持部から線状部材が外れることを第２保持部が防止し、第２保持部から線状部材が外れることを第１保持部が防止する。すなわち、線状部材に対して、一方の保持部の線状部材挿し込み方向と反対の方向に外力が作用しても、他方の保持部が線状部材を保持する。このため、金属線に保持部からの線状部材の外れを防止するための特別の部位を形成する必要はなく、クランプ装置の構成が複雑化することを防止することができる。したがって、このクランプ装置は、線状部材がクランプ装置から外れることを好適に防止することができる。   In this clamp device, the second holding part prevents the linear member from coming off from the first holding part, and the first holding part prevents the linear member from coming off from the second holding part. That is, even if an external force acts on the linear member in a direction opposite to the linear member insertion direction of one holding portion, the other holding portion holds the linear member. For this reason, it is not necessary to form the special site | part for preventing the detachment | leave of the linear member from a holding | maintenance part in a metal wire, and it can prevent that the structure of a clamp apparatus becomes complicated. Therefore, this clamp apparatus can prevent suitably that a linear member remove | deviates from a clamp apparatus.

上記のクランプ装置では、さらに、第１保持部への線状部材の挿し込み方向と、第２保持部への線状部材の挿し込み方向とがなす角が、９０〜２７０°の範囲となることが好ましい。このような構成によると、クランプ装置から線状部材がより外れ難くすることができる。   In the above clamping device, the angle formed by the insertion direction of the linear member into the first holding part and the insertion direction of the linear member into the second holding part is in the range of 90 to 270 °. It is preferable. According to such a configuration, the linear member can be more easily removed from the clamping device.

（第１実施例） 本発明を具現化した第１実施例に係るクランプ装置１０を説明する。第１実施例に係るクランプ装置１０は、自動車の排気管に取付けられるセンサ（例えば、排気ガス中の酸素濃度を検知する酸素センサ等）のワイヤハーネスを保持し、そのワイヤハーネスの配索経路を規制するために用いられる。図１，２に示すように、クランプ装置１０は、１本の金属線（例えば、硬鋼線，ピアノ線，ステンレス鋼線等）を曲折して形成されている。クランプ装置１０は、ワイヤハーネスＨを保持する第１保持部１２と、第１保持部とは異なる位置でワイヤハーネスＨを保持する第２保持部１４を有している。 First Embodiment A clamp device 10 according to a first embodiment that embodies the present invention will be described. The clamp device 10 according to the first embodiment holds a wire harness of a sensor (for example, an oxygen sensor that detects an oxygen concentration in exhaust gas) attached to an exhaust pipe of an automobile, and the wiring route of the wire harness Used to regulate. As shown in FIGS. 1 and 2, the clamp device 10 is formed by bending one metal wire (for example, a hard steel wire, a piano wire, a stainless steel wire, etc.). The clamp device 10 includes a first holding part 12 that holds the wire harness H and a second holding part 14 that holds the wire harness H at a position different from the first holding part.

図２によく示されるように、第１保持部１２は、金属線を略Ｕ字状に曲折することで形成されている。第１保持部１２の上方（略Ｕ字状に曲折された金属線の上端）は開口しており、その幅はワイヤハーネスＨの外径よりも小さくされている。第１保持部１２の底部は、ワイヤハーネスＨの外形に倣うように半円状に形成されており、その径はワイヤハーネスＨの外径よりわずかに小さい。第１保持部１２にワイヤハーネスＨを取付けるには、第１保持部１２の上方より第１保持部１２の底部に向かってワイヤハーネスＨを挿し込む。第１保持部１２の開口の幅はワイヤハーネスＨの径より小さいため、ワイヤハーネスＨを挿し込む際は、第１保持部１２の上端が外側に開く方向に変形する。ワイヤハーネスＨが第１保持部１２の底部まで挿し込まれると、第１保持部１２はその復元力によって元の形状に戻ろうとする。この復元力によって、ワイヤハーネスＨが第１保持部１２に保持（挟持）される。上記の説明から明らかなように、第１保持部１２へのワイヤハーネスＨの挿し込み方向は下方（すなわち、矢印Ａの方向）となっている。   As well shown in FIG. 2, the first holding portion 12 is formed by bending a metal wire into a substantially U shape. The upper part of the first holding part 12 (the upper end of the metal wire bent in a substantially U shape) is opened, and the width thereof is made smaller than the outer diameter of the wire harness H. The bottom of the first holding part 12 is formed in a semicircular shape so as to follow the outer shape of the wire harness H, and the diameter thereof is slightly smaller than the outer diameter of the wire harness H. In order to attach the wire harness H to the first holding unit 12, the wire harness H is inserted from above the first holding unit 12 toward the bottom of the first holding unit 12. Since the opening width of the first holding portion 12 is smaller than the diameter of the wire harness H, when the wire harness H is inserted, the upper end of the first holding portion 12 is deformed in a direction to open outward. When the wire harness H is inserted to the bottom of the first holding part 12, the first holding part 12 tries to return to its original shape by its restoring force. With this restoring force, the wire harness H is held (clamped) by the first holding portion 12. As is clear from the above description, the insertion direction of the wire harness H into the first holding portion 12 is downward (that is, the direction of the arrow A).

第１保持部１２の一端側には取付部１８が形成されている。取付部１８は、第１保持部１２の一端より伸びている金属線を曲折することで形成されており、図示しないブラケットに固定される。取付部１８をブラケットに固定することで、クランプ装置１０がブラケットに固定される。一方、第１保持部１２の他端側には接続部１６が形成されている。接続部１６は、第１保持部１２の他端より伸びている金属線を曲折することで形成されており、その先端が第２保持部１４に接続されている。すなわち、接続部１６は、第１保持部１２と第２保持部１４の間に配置され、第１保持部１２と第２保持部１４を接続している。第１保持部１２と第２保持部１４の間に接続部１６が配置されるため、第１保持部１２と第２保持部１４は、ワイヤハーネスＨの軸方向に離れた部位をそれぞれ保持する。   An attachment portion 18 is formed on one end side of the first holding portion 12. The attachment portion 18 is formed by bending a metal wire extending from one end of the first holding portion 12, and is fixed to a bracket (not shown). By fixing the attachment portion 18 to the bracket, the clamp device 10 is fixed to the bracket. On the other hand, a connecting portion 16 is formed on the other end side of the first holding portion 12. The connecting portion 16 is formed by bending a metal wire extending from the other end of the first holding portion 12, and the tip thereof is connected to the second holding portion 14. That is, the connection unit 16 is disposed between the first holding unit 12 and the second holding unit 14 and connects the first holding unit 12 and the second holding unit 14. Since the connection part 16 is arrange | positioned between the 1st holding | maintenance part 12 and the 2nd holding | maintenance part 14, the 1st holding | maintenance part 12 and the 2nd holding | maintenance part 14 hold | maintain the site | part away from the axial direction of the wire harness H, respectively. .

第２保持部１４は、第１保持部１２と略同様の構成を備えており、金属線を略Ｕ字状に曲折することで形成されている。ただし、第２保持部１４は、第１保持部１２と異なり、図２の右側方が開口する一方で、図２の左側方がワイヤハーネスＨの外形に倣うように半円状に形成されている。したがって、第２保持部１４にワイヤハーネスＨを取付けるには、第２保持部１４の右側方よりワイヤハーネスＨを挿し込むこととなる。すなわち、第２保持部１４へのワイヤハーネスＨの挿し込み方向は左側方（すなわち、矢印Ｂの方向）となる。したがって、図２に示すように、第１保持部１２へのワイヤハーネスＨの挿し込み方向（矢印Ａの方向）と、第２保持部１４へのワイヤハーネスＨの挿し込み方向（矢印Ｂの方向）とがなす角（すなわち、後者の方向（矢印Ｂ）を表す単位ベクトルと前者の方向（矢印Ａ）を表す単位ベクトルの終点とが一致するように２つのベクトルを描いたときになす角度であって、後者から前者に向かって時計回りに計測したときの角度）は９０°となっている。   The second holding portion 14 has a configuration substantially similar to that of the first holding portion 12 and is formed by bending a metal wire into a substantially U shape. However, unlike the first holding part 12, the second holding part 14 is formed in a semicircular shape so that the right side in FIG. 2 opens while the left side in FIG. 2 follows the outer shape of the wire harness H. Yes. Therefore, in order to attach the wire harness H to the second holding part 14, the wire harness H is inserted from the right side of the second holding part 14. That is, the insertion direction of the wire harness H into the second holding portion 14 is the left side (that is, the direction of the arrow B). Therefore, as shown in FIG. 2, the insertion direction of the wire harness H into the first holding part 12 (direction of arrow A) and the insertion direction of the wire harness H into the second holding part 14 (direction of arrow B) ) (That is, the angle formed when two vectors are drawn so that the unit vector representing the latter direction (arrow B) and the end point of the unit vector representing the former direction (arrow A) coincide. The angle when measured clockwise from the latter to the former is 90 °.

なお、第２保持部１４の開口部では、上方の金属線が下方の金属線より右側に突出して形成されている。（すなわち、Ｕ字状に形成された金属線の一方が他方より長くされている（図２参照）。）このため、第２保持部１４にワイヤハーネスＨを挿し込む際は、第２保持部１４の上方の金属線にワイヤハーネスＨを案内させながら行うことができる。これによって、第２保持部１４へのワイヤハーネスＨの挿し込みを容易に行うことができる。   In addition, in the opening part of the 2nd holding | maintenance part 14, an upper metal wire protrudes and is formed in the right side from a lower metal wire. (That is, one of the U-shaped metal wires is longer than the other (see FIG. 2).) For this reason, when the wire harness H is inserted into the second holding part 14, the second holding part. It can carry out, guiding the wire harness H to the metal wire of 14 upper. Thereby, the wire harness H can be easily inserted into the second holding portion 14.

上述したクランプ装置１０にワイヤハーネスＨを取付けるには、クランプ装置１０の第１保持部１２にワイヤハーネスＨを挿し込むと共に、第２保持部１４にワイヤハーネスＨを挿し込む。すなわち、第１保持部１２には上方からワイヤハーネスＨを挿し込み、第２保持部１４には図２の右側方よりワイヤハーネスＨを挿し込む。第１保持部１２へのワイヤハーネスＨの挿し込み方向（矢印Ａの方向）と、第２保持部１４へのワイヤハーネスＨの挿し込み方向（矢印Ｂの方向）とは相違しているが、第１保持部１２と第２保持部１４の間には接続部１６が形成され、第１保持部１２と第２保持部１４はワイヤハーネスＨの軸方向に離れた位置に配置されている。また、接続部１６は、図２の方向から見たときにワイヤハーネスＨの周囲を一巡することなく、第２保持部１４の開口部の方向（矢印Ｂと逆の方向）を開放している。これらのため、クランプ装置１０をブラケットに固定した状態のままワイヤハーネスＨのみを曲げ変形させて、ワイヤハーネスＨを第１保持部１２及び第２保持部１４に挿し込むことができる。これによって、ワイヤハーネスＨをクランプ装置１０に容易に取付けることができる。ワイヤハーネスＨが第１保持部１２及び第２保持部１４に保持されると、ワイヤハーネスＨはクランプ装置１０に２箇所で保持され、その配索経路が規制される。   In order to attach the wire harness H to the clamp device 10 described above, the wire harness H is inserted into the first holding portion 12 of the clamp device 10 and the wire harness H is inserted into the second holding portion 14. That is, the wire harness H is inserted into the first holding part 12 from above, and the wire harness H is inserted into the second holding part 14 from the right side of FIG. The insertion direction of the wire harness H into the first holding part 12 (direction of arrow A) is different from the insertion direction of the wire harness H into the second holding part 14 (direction of arrow B). A connecting portion 16 is formed between the first holding portion 12 and the second holding portion 14, and the first holding portion 12 and the second holding portion 14 are arranged at positions separated in the axial direction of the wire harness H. Further, the connection portion 16 opens the direction of the opening of the second holding portion 14 (the direction opposite to the arrow B) without making a round around the wire harness H when viewed from the direction of FIG. . For these reasons, only the wire harness H can be bent and deformed while the clamp device 10 is fixed to the bracket, and the wire harness H can be inserted into the first holding part 12 and the second holding part 14. Thereby, the wire harness H can be easily attached to the clamping device 10. If the wire harness H is hold | maintained at the 1st holding | maintenance part 12 and the 2nd holding | maintenance part 14, the wire harness H will be hold | maintained by the clamp apparatus 10 at two places, and the routing route will be controlled.

ここで、クランプ装置１０にワイヤハーネスＨを保持した状態で、第１保持部１２からワイヤハーネスＨを外す方向（図２の矢印Ａと逆向きの方向）に外力が作用した場合、その外力は第２保持部１４を形成する金属線によって受けることができる。これによって、第１保持部１２からワイヤハーネスＨが外れることが防止される。また、仮に第１保持部１２からワイヤハーネスＨが外れてしまったときでも、ワイヤハーネスＨに作用する外力の方向（矢印Ａと逆向きの方向）は、第２保持部１４からワイヤハーネスＨを外す方向（図２の矢印Ｂと逆向きの方向）に対して直交している。このため、第２保持部１４からワイヤハーネスＨが外れることを防止できる。   Here, in the state where the wire harness H is held in the clamp device 10, when an external force is applied in a direction in which the wire harness H is removed from the first holding portion 12 (a direction opposite to the arrow A in FIG. 2), the external force is It can be received by a metal wire forming the second holding part 14. This prevents the wire harness H from being detached from the first holding part 12. Even if the wire harness H is detached from the first holding portion 12, the direction of the external force acting on the wire harness H (the direction opposite to the arrow A) is the wire harness H from the second holding portion 14. It is orthogonal to the direction to remove (the direction opposite to the arrow B in FIG. 2). For this reason, it is possible to prevent the wire harness H from being detached from the second holding portion 14.

逆に、クランプ装置１０にワイヤハーネスＨを保持した状態で、第２保持部１４からワイヤハーネスＨを外す方向（図２の矢印Ｂと逆向きの方向）に外力が作用した場合、その外力は第１保持部１２を形成する金属線によって受けることができる。これによって、第２保持部１４からワイヤハーネスＨが外れることが防止される。また、仮に第２保持部１４からワイヤハーネスＨが外れてしまったときでも、ワイヤハーネスＨに作用する外力の方向（矢印Ｂと逆向きの方向）は、第１保持部１２からワイヤハーネスＨを外す方向（図２の矢印Ａと逆向きの方向）に対して直交する。このため、第１保持部１２からワイヤハーネスＨが外れることを防止できる。   Conversely, in the state where the wire harness H is held in the clamp device 10, when an external force is applied in the direction in which the wire harness H is removed from the second holding portion 14 (the direction opposite to the arrow B in FIG. 2), the external force is It can be received by a metal wire forming the first holding part 12. This prevents the wire harness H from being detached from the second holding portion 14. Even if the wire harness H is detached from the second holding portion 14, the direction of the external force acting on the wire harness H (the direction opposite to the arrow B) is the wire harness H from the first holding portion 12. It is orthogonal to the direction to remove (the direction opposite to the arrow A in FIG. 2). For this reason, it can prevent that the wire harness H remove | deviates from the 1st holding | maintenance part 12. FIG.

上述した説明から明らかなように、第１実施例のクランプ装置１０では第１保持部１２へのワイヤハーネスＨの挿し込み方向（矢印Ａ）と、第２保持部１４へのワイヤハーネスＨの挿し込み方向（矢印Ｂ）とがなす角が９０°となっている。これによって、クランプ装置１０からワイヤハーネスＨが外れることを好適に防止することができる。   As is clear from the above description, in the clamping device 10 of the first embodiment, the insertion direction (arrow A) of the wire harness H into the first holding part 12 and the insertion of the wire harness H into the second holding part 14. The angle formed by the insertion direction (arrow B) is 90 °. Thereby, it can prevent suitably that the wire harness H remove | deviates from the clamp apparatus 10. FIG.

（第２実施例） 次に、第２実施例のクランプ装置について説明する。第２実施例のクランプ装置は、第１実施例のクランプ装置１０と異なり、第２保持部の開口する方向が相違しており、その他の点は第１実施例のクランプ装置１０と略同一となっている。このため、第１実施例のクランプ装置１０と相違する点を主に説明する。 Second Embodiment Next, a clamp device according to a second embodiment will be described. The clamping device of the second embodiment differs from the clamping device 10 of the first embodiment in that the opening direction of the second holding portion is different, and the other points are substantially the same as the clamping device 10 of the first embodiment. It has become. For this reason, the difference from the clamping device 10 of the first embodiment will be mainly described.

図３，４に示すように、第２実施例のクランプ装置３０も、１本の金属線を曲折して形成されており、取付部３８と第１保持部３２と接続部３６と第２保持部３４を有している。取付部３８と第１保持部３２は、第１実施例と同様に構成されており、第２保持部３４と接続部３６が第１実施例とは異なる。   As shown in FIGS. 3 and 4, the clamping device 30 of the second embodiment is also formed by bending one metal wire, and includes a mounting portion 38, a first holding portion 32, a connecting portion 36, and a second holding portion. Part 34 is provided. The attachment portion 38 and the first holding portion 32 are configured in the same manner as in the first embodiment, and the second holding portion 34 and the connection portion 36 are different from those in the first embodiment.

第２保持部３４は、金属線を略Ｕ字状に曲折することで形成されており、図４に示されるように、下方が開口する一方で、上方がワイヤハーネスＨの外形に倣うように半円状に形成されている。このため、第２保持部３４にワイヤハーネスＨを取付けるには、第２保持部３４の下方よりワイヤハーネスＨを挿し込むこととなる。したがって、第１保持部３２へのワイヤハーネスＨの挿し込み方向（矢印Ａの方向）と、第２保持部３４へのワイヤハーネスＨの挿し込み方向（矢印Ｂの方向）とがなす角は１８０°となっている。   The second holding portion 34 is formed by bending a metal wire into a substantially U shape. As shown in FIG. 4, the lower portion opens while the upper portion follows the outer shape of the wire harness H. It is formed in a semicircular shape. For this reason, in order to attach the wire harness H to the second holding part 34, the wire harness H is inserted from below the second holding part 34. Therefore, the angle formed by the direction in which the wire harness H is inserted into the first holding part 32 (in the direction of arrow A) and the direction in which the wire harness H is inserted into the second holding part 34 (in the direction of arrow B) is 180. It is °.

上述したように、第２保持部３４へのワイヤハーネスＨの挿し込み方向が第１実施例とは異なるため、それに応じて接続部３６の形状が第１実施例とは相違している。ただし、接続部３６の機能（すなわち、第１保持部３２と第２保持部３４を接続するという機能）については、第１実施例と同様である。   As described above, since the insertion direction of the wire harness H into the second holding portion 34 is different from that of the first embodiment, the shape of the connecting portion 36 is different from that of the first embodiment accordingly. However, the function of the connecting portion 36 (that is, the function of connecting the first holding portion 32 and the second holding portion 34) is the same as that of the first embodiment.

第２実施例のクランプ装置３０では、第１保持部３２へのワイヤハーネスＨの挿し込み方向（矢印Ａ）と、第２保持部１４へのワイヤハーネスＨの挿し込み方向（矢印Ｂ）とがなす角が１８０°となっている。このため、第１保持部３２からワイヤハーネスＨを外す方向（図４の矢印Ａと逆向きの方向）に作用する外力を第２保持部３４によって受けることができ、また、第２保持部３４からワイヤハーネスＨを外す方向（図４の矢印Ｂと逆向きの方向）に作用する外力を第１保持部３２によって受けることができる。このため、クランプ装置３０からのワイヤハーネスＨの外れを好適に防止することができる。   In the clamping device 30 of the second embodiment, the insertion direction (arrow A) of the wire harness H into the first holding part 32 and the insertion direction (arrow B) of the wire harness H into the second holding part 14 are determined. The formed angle is 180 °. Therefore, an external force acting in the direction of removing the wire harness H from the first holding part 32 (direction opposite to the arrow A in FIG. 4) can be received by the second holding part 34, and the second holding part 34 The first holding part 32 can receive an external force that acts in a direction in which the wire harness H is removed from (a direction opposite to the arrow B in FIG. 4). For this reason, detachment of the wire harness H from the clamp device 30 can be suitably prevented.

また、第１保持部３２と第２保持部３４の間には接続部３６が形成され、接続部３６は、図４の方向から見たときにワイヤハーネスＨの左側方にのみ位置している。このため、クランプ装置３０をブラケットに固定した状態のままワイヤハーネスＨのみを曲げ変形させて、ワイヤハーネスＨをクランプ装置３０に取付けることができる。   Moreover, the connection part 36 is formed between the 1st holding | maintenance part 32 and the 2nd holding | maintenance part 34, and the connection part 36 is located only in the left side of the wire harness H when it sees from the direction of FIG. . For this reason, it is possible to attach the wire harness H to the clamp device 30 by bending and deforming only the wire harness H while the clamp device 30 is fixed to the bracket.

（第３実施例） 次に、第３実施例のクランプ装置について説明する。第３実施例のクランプ装置５０は、第１実施例のクランプ装置１０と異なり、第２保持部が開口する方向が相違し、その他の点は第１実施例のクランプ装置１０と略同一となっている。 Third Example Next, a clamp device according to a third example will be described. Unlike the clamp device 10 of the first embodiment, the clamp device 50 of the third embodiment is different in the direction in which the second holding portion opens, and the other points are substantially the same as the clamp device 10 of the first embodiment. ing.

すなわち、図５，６に示すように、第３実施例のクランプ装置５０も、１本の金属線を曲折して形成されており、取付部５８と第１保持部５２と接続部５６と第２保持部５４を有している。取付部５８と第１保持部５２は、第１実施例の取付部１８と第１保持部１２と同一構成であり、第２保持部５４と接続部５６が第１実施例とは異なる。   That is, as shown in FIGS. 5 and 6, the clamping device 50 of the third embodiment is also formed by bending one metal wire, and the mounting portion 58, the first holding portion 52, the connecting portion 56, 2 holding part 54 is provided. The mounting portion 58 and the first holding portion 52 have the same configuration as the mounting portion 18 and the first holding portion 12 of the first embodiment, and the second holding portion 54 and the connecting portion 56 are different from the first embodiment.

第２保持部５４は、金属線を略Ｕ字状に曲折することで形成されており、図６に示されるように、左側方が開口する一方で、右側方がワイヤハーネスＨの外形に倣うように半円状に形成されている。このため、第２保持部５４にワイヤハーネスＨを取付けるには、第２保持部５４の左側方よりワイヤハーネスＨを挿し込むこととなる。したがって、第１保持部５２へのワイヤハーネスＨの挿し込み方向（矢印Ａの方向）と、第２保持部５４へのワイヤハーネスＨの挿し込み方向（矢印Ｂの方向）とがなす角は２７０°となっている。なお、第２保持部５４へのワイヤハーネスＨの挿し込み方向に応じて、接続部５６の形状が第１実施例と相違している点は、上述した第２実施例と同様である。   The second holding portion 54 is formed by bending a metal wire into a substantially U shape. As shown in FIG. 6, the left side opens while the right side follows the outer shape of the wire harness H. It is formed in a semicircle shape. For this reason, in order to attach the wire harness H to the second holding part 54, the wire harness H is inserted from the left side of the second holding part 54. Therefore, the angle formed by the insertion direction of the wire harness H into the first holding part 52 (direction of arrow A) and the insertion direction of the wire harness H into the second holding part 54 (direction of arrow B) is 270. It is °. In addition, the point from which the shape of the connection part 56 differs from 1st Example according to the insertion direction of the wire harness H to the 2nd holding | maintenance part 54 is the same as that of 2nd Example mentioned above.

第３実施例のクランプ装置５０でも、第１保持部５２からワイヤハーネスＨを外す方向（図６の矢印Ａと逆向きの方向）に作用する外力を第２保持部５４によって受けることができ、また、第２保持部５４からワイヤハーネスＨを外す方向（図６の矢印Ｂと逆向きの方向）に作用する外力を第１保持部５２によって受けることができる。このため、クランプ装置３０からのワイヤハーネスＨの外れを好適に防止することができる。   Even in the clamping device 50 of the third embodiment, an external force acting in the direction of removing the wire harness H from the first holding part 52 (direction opposite to the arrow A in FIG. 6) can be received by the second holding part 54, Further, the first holding part 52 can receive an external force acting in the direction of removing the wire harness H from the second holding part 54 (the direction opposite to the arrow B in FIG. 6). For this reason, detachment of the wire harness H from the clamp device 30 can be suitably prevented.

また、第１保持部５２と第２保持部５４の間には接続部５６が形成され、また、接続部５６は、図６の方向から見たときにワイヤハーネスＨの周囲を一巡していない。このため、クランプ装置５０をブラケットに固定した状態のままワイヤハーネスＨのみを曲げ変形させて、ワイヤハーネスＨをクランプ装置５０に取付けることができる。   Moreover, the connection part 56 is formed between the 1st holding | maintenance part 52 and the 2nd holding | maintenance part 54, and the connection part 56 does not go around the circumference | surroundings of the wire harness H when it sees from the direction of FIG. . For this reason, it is possible to attach the wire harness H to the clamp device 50 by bending and deforming only the wire harness H while the clamp device 50 is fixed to the bracket.

（参考例） 次に、参考例のクランプ装置について簡単に説明する。図７，８に示すように、参考例のクランプ装置７０は、１本の金属線を曲折して形成されており、取付部７８と第１保持部７２と接続部７６と第２保持部７４を有している。取付部７８と第１保持部７２は、第１実施例の取付部１８と第１保持部１２と同一構成であり、第２保持部７４と接続部７６が第１実施例とは異なる。 (Reference example) Next, the clamp apparatus of a reference example is demonstrated easily. As shown in FIGS. 7 and 8, the clamping device 70 of the reference example is formed by bending one metal wire, and includes a mounting portion 78, a first holding portion 72, a connecting portion 76, and a second holding portion 74. have. The attachment portion 78 and the first holding portion 72 have the same configuration as the attachment portion 18 and the first holding portion 12 of the first embodiment, and the second holding portion 74 and the connecting portion 76 are different from those of the first embodiment.

第２保持部７４は、金属線を略Ｕ字状に曲折することで形成され、図７，８に示されるように、第１保持部７２と同様に構成されている。すなわち、第２保持部７４の上方が開口する一方で、下方がワイヤハーネスＨの外形に倣うように半円状に形成されている。このため、第２保持部７４へのワイヤハーネスＨの挿し込み方向は、第１保持部７２へのワイヤハーネスＨの挿し込み方向と同一となっている。接続部７６は、その一端が第１保持部７２に接続される一方で、その他端が第２保持部７４に接続されている。図７，８に示すように、接続部７６は、第１保持部７２及び第２保持部７４に保持されたワイヤハーネスＨの上方に位置するように形成されている。すなわち、接続部７６は、第１保持部７２及び第２保持部７４から見て、第１保持部７２及び第２保持部７４からワイヤハーネスＨを外す方向に位置するように形成されている。   The second holding portion 74 is formed by bending a metal wire into a substantially U shape, and is configured similarly to the first holding portion 72 as shown in FIGS. That is, the upper part of the second holding part 74 is opened, while the lower part is formed in a semicircular shape so as to follow the outer shape of the wire harness H. For this reason, the insertion direction of the wire harness H into the second holding part 74 is the same as the insertion direction of the wire harness H into the first holding part 72. The connection part 76 has one end connected to the first holding part 72 and the other end connected to the second holding part 74. As shown in FIGS. 7 and 8, the connecting portion 76 is formed so as to be located above the wire harness H held by the first holding portion 72 and the second holding portion 74. That is, the connecting portion 76 is formed so as to be positioned in a direction in which the wire harness H is removed from the first holding portion 72 and the second holding portion 74 when viewed from the first holding portion 72 and the second holding portion 74.

したがって、参考例のクランプ装置７０では、ワイヤハーネスＨに対して、保持部７２，７４から外れる方向（すなわち上向き）の力が作用しても、接続部７６がワイヤハーネスＨの上方（すなわち、保持部７２，７４からワイヤハーネスＨを外す方向）に位置し、この接続部７６によって保持部７２，７４からワイヤハーネスＨを外す方向の外力を受けることができる。したがって、参考例のクランプ装置７０でも、クランプ装置７０からのワイヤハーネスＨの外れが防止される。   Therefore, in the clamping device 70 of the reference example, even if a force in a direction away from the holding portions 72 and 74 (that is, upward) acts on the wire harness H, the connection portion 76 is above the wire harness H (that is, held). The connecting portion 76 can receive an external force in the direction of removing the wire harness H from the holding portions 72 and 74. Therefore, even in the clamping device 70 of the reference example, the wire harness H is prevented from coming off from the clamping device 70.
