  Hereinafter, a control cable of the present invention will be described in detail with reference to the accompanying drawings.

  Hereinafter, although one embodiment of the present invention is described using Drawing 1-Drawing 5 (b), this embodiment is an example to the last, and is not limited to this embodiment.

  As shown in FIGS. 1 and 2, the control cable 1 of the present invention has an outer casing 2 and a regulating member 3 that regulates the routing of the outer casing 2. The outer casing 2 is provided with a terminal member 4 at an end portion thereof, the vicinity of the terminal member 4 is curved, and the outer casing 2 is held by the regulating member 3 in a curved state. “The vicinity of the terminal member 4 is curved” means that the end casing member 4 of the outer casing 2 on the side to be curved provided with the terminal member 4 is curved. The state which the edge part curved is said, and the case where there is a slight linear part in the edge part of the outer casing 2 is also included. In addition, as shown in FIGS. 1 and 2, the “curved” in this specification is not limited to the curved outer casing 2 arranged so as to change the direction by 180 °, and the curved outer casing 2 is not limited thereto. The angle of the casing 2 is not limited. An inner cable I is inserted into the outer casing 2, and an operating force transmitted from one of the cable ends I1 and I2 provided at both ends of the inner cable I is transmitted to the other. The structure of the inner cable I is not particularly limited, and description thereof is omitted.

  The terminal member 4 is attached via a bracket B (see FIGS. 5A and 5B) to a desired place where the control cable 1 such as a vehicle is to be routed. The terminal member 4 has a small-diameter portion 41 in FIGS. 1 and 2 so that it can be attached to a notch Bn (see FIGS. 5A and 5B) formed in a plate-like bracket. The small-diameter portion 41 between the large-diameter portions 42 formed on both sides in the axial direction of the small-diameter portion 41 is connected to the notch portion Bn having a size corresponding to the small-diameter portion 41 formed in the bracket B with the axial direction of the small-diameter portion 41. The terminal member 4 can be attached to the bracket B by pushing in the vertical direction. The shape of the terminal member 4 shown in FIGS. 1 and 2 is merely an example, and the shape and structure are not particularly limited as long as the terminal member 4 is fixed to the bracket B by being pushed into the bracket B. Further, in this specification, the bracket B refers to a portion for fixing the terminal member 4 and is not particularly limited as long as the terminal member 4 can be fixed. A structure other than fixing by the notch Bn may be used.

  In the embodiment shown in FIG. 2, the regulating member 3 is composed of a single wire, and is formed by bending a single wire. As shown in FIG. 2, the regulating member 3 does not need to be formed from a single wire. Alternatively, they may be integrated or formed by combining different members. In addition, when the restriction member 3 is comprised with one wire, the process of the restriction member 3 becomes easy and the manufacturing cost of the restriction member 3 can be reduced.

  1 to 3C, the regulating member 3 of the embodiment engages with the vicinity of the terminal member 4 and regulates from the outer side 2o of the outer casing 2 so as to maintain the curved state of the outer casing 2. The outer outer holding portion 31 is engaged with the bending end position CE where the outer casing 2 has been bent from the terminal member 4 side of the outer casing 2, and the bending is regulated from the outer side 2 o so as to hold the curved state of the outer casing 2. The end side outer holding portions 32a and 32b (hereinafter, the reference end 32 is generally used when referring to the bending end side outer holding portion), the terminal member side outer holding portion 31 and the bending end side outer holding portion 32a. And a connecting portion 33 to be connected.

  The outer side 2o of the outer casing 2 refers to a portion of the outer surface of the outer casing 2 in FIG. 1 that has a larger radius of curvature (the outer surface on the right side of the curved portion of the outer casing 2 in FIG. 1). In addition, the inner side 2i of the outer casing 2 to be described later refers to a portion of the outer surface of the outer casing 2 in FIG. 1 that has a smaller radius of curvature (the left side of the curved portion of the outer casing 2 in FIG. 1). Outside surface). Here, the radius of curvature does not mean the exact radius of curvature of a circle but indicates the magnitude of the bending of the outer casing 2. Further, the bending end position CE refers to the end of one curved portion of the outer casing 2, and is separated from the bending end position CE (for example, further to the left side of the bending end position CE in FIG. 1). A curved portion may be provided in the casing 2.

  In the embodiment shown in FIG. 2 and FIG. 3B, the terminal member side outer holding portion 31 is formed in a hook shape curved in a substantially U shape. As will be described in detail later, the hook-shaped end member-side outer holding portion 31 shown in FIGS. 2 and 3B is formed with an opening 31A that is wider than the diameter of the outer casing 2, and the end-member-side outer holding portion 31 is formed. From the opening 31 </ b> A of the portion 31, the outer casing 2 can be attached to the terminal member side outer holding portion 31.

  As shown in FIGS. 1, 2, and 3 (a), the connecting portion 33 extends linearly from the terminal member-side outer holding portion 31 toward the curved terminal-side outer holding portion 32. At the bending end position CE of the outer casing 2, a bending end side outer holding portion 32a bent in a substantially U shape is formed.

  In the embodiment of FIGS. 1, 2 and 3A to 3C, a curved terminal side outer holding part 32b described later is provided in addition to the curved terminal side outer holding part 32a. Since 2 is curved and routed, the outer casing 2 is regulated from the outer side 2o of the outer casing 2 so as to maintain the curved state of the outer casing 2 at least in the vicinity of the terminal member 4 and at the bending end position CE. It only has to be done. Therefore, the bending end side outer holding portion 32 is not limited to the one having the two bending end side outer holding portions 32a and 32b as in the illustrated embodiment, and may be one or three or more bending portions. The terminal side outer holding part 32 may be provided. Note that “holding the curved state” means that when the outer casing 2 is bent from a linear state, a force is applied in a direction in which the outer casing 2 tends to be linear. This means that the outer holding portion 31 and the bending end side outer holding portion 32 are pressed. Similarly to the curved terminal side outer holding part 32, the terminal member side outer holding part 31 may be one as in the illustrated embodiment, or two or more terminal member side outer holding parts 31 are provided. May be.

  Further, the force in the direction in which the curved outer casing 2 tends to spread, that is, the force that tends to be linear, is directed toward the outer side 2o of the outer casing 2 (in the vicinity of the terminal member 4 in FIG. 1 from the lower side in FIG. 1 and further from the upper side in FIG. 1 of the outer casing 2 at the curved end position CE in FIG. The part which controls the movement of the casing 2 should just be provided at least partially. Therefore, the terminal member side outer holding portion 31 and the curved end side outer holding portion 32 do not have to be substantially U-shaped as shown in FIGS. 2 and 3B, and the outer casing 2 is likely to expand. As long as the outer casing 2 can be pressed from the direction in which the outer casing 2 is pressed (hereinafter referred to as the regulation direction X, see FIGS. 4A and 4B), it may be substantially C-shaped. , May be substantially V-shaped.

  As shown in FIG. 1 and FIG. 2, the terminal member side outer holding portion 31 and the curved end side outer holding portion 32 are connected by a connecting portion 33, and the connecting portion 33 is formed so that the outer casing 2 becomes linear. This force is regulated so that the distance between the terminal member-side outer holding portion 31 and the curved end-side outer holding portion 32 is not widened. The terminal member side outer holding portion 31, the curved end side outer holding portion 32, and the connecting portion 33 are not particularly limited as long as they have rigidity sufficient to withstand the force that the outer casing 2 tends to be linear. It can be formed of a synthetic resin or a metal material.

  In the embodiment shown in FIGS. 1, 2, and 3 (a), the connecting portion 33 is formed so as to be linearly connected between the terminal member side outer holding portion 31 and the curved end side outer holding portion 32. However, as long as the outer casing 2 is rigid enough to withstand the force of trying to be linear, the outer casing 2 does not need to be linear, and the connecting portion 33 itself is curved or bent. Moreover, it may be a plate-like connecting portion 33 instead of a rod shape, and the shape of the connecting portion 33 is not limited.

  As described above, the terminal member-side outer holding portion 31 holds the curved state of the outer casing 2 and further allows the outer casing 2 to move in a direction different from the regulation direction X of the outer casing 2. When the restriction member 3 provided in the vicinity of the terminal member 4 is gripped and the terminal member 4 is inserted into the bracket B of the vehicle, the terminal member 4 is damaged by an excessive force applied when the bracket B of the terminal member 4 is inserted. You can avoid that. That is, when the outer casing 2 is attached to the bracket B so that the outer casing 2 does not move by the terminal member-side outer holding portion 31 on the regulation direction X side where the outer casing 2 tends to spread, 2 can be maintained, and the bracket B is not allowed to move by allowing movement in a direction different from the regulation direction X, for example, in a direction opposite to the direction in which the terminal member 4 is attached to the bracket B. When the terminal member 4 is about to be attached, the outer casing 2 can escape in the direction in which the movement of the outer casing 2 is allowed (the direction indicated by the reference symbol Y in FIG. 4A), and the terminal member 4 is damaged. Can be prevented in advance. In particular, when the bracket B is provided in a place where the terminal member 4 itself is gripped and is difficult to attach, the position away from the terminal member 4 of the control cable 1 is gripped as shown in FIG. When the terminal member 4 is to be inserted, the distance between the gripping position of the control cable 1 and the notch Bn, which is the fixing position of the bracket B, becomes long. It becomes difficult, and the terminal member 4 is in a state of partially entering the notch Bn with the terminal member 4 tilted. In this state, if the outer casing 2 cannot be moved in a direction different from the regulation direction X, the terminal member 4 may be damaged if the control cable 1 is gripped and is directly pushed into the notch Bn. On the other hand, when the movement of the outer casing 2 is allowed in a direction different from the regulation direction X, only the outer casing 2 is deformed as shown in FIG. The terminal member 4 will not be damaged because it moves in the direction away from the contacted state (the Y direction in FIG. 4A, the upward direction in FIG. 5B).

  4 (a), 5 (a) and 5 (b), the outer casing 2 is allowed to move in the direction opposite to the regulation direction X, but the direction in which the movement is allowed is other than the regulation direction X. Yes, as long as the curved state of the outer casing 2 can be maintained when the control cable 1 is attached to the bracket B. As shown in FIG. May be allowed to move in any direction (direction indicated by reference numeral Y2). In addition, as shown to Fig.4 (a), not only the terminal member side outer holding | maintenance part 31 but the curved terminal side outer holding | maintenance part 32 side is permitted by the movement of the outer casing 2 in the direction different from the regulation direction X. When the terminal member 4 is to be attached to the bracket B by gripping the vicinity of the curved end position CE of the outer casing 2 without gripping the regulating member 3, the terminal member side outer holding portion 31 and the curved end side outer holding Since the movement of the outer casing 2 (the Y direction in FIG. 4A and the direction indicated by the reference symbol Y3) is allowed in both the portions 32, the terminal member 4 can be further prevented from being damaged.

  In order to allow the movement of the outer casing 2, the outer casing 2 moves in a direction different from the regulation direction X of the outer casing 2, as shown in FIGS. 4A and 4B. An opening 31A can be provided so as to be possible. The opening 31A not only allows the movement of the outer casing 2 and avoids damage to the terminal member 4, but also functions as an attachment opening for attaching the outer casing 2 to the restricting member 3. Attachment of the casing 2 and avoidance of breakage of the terminal member 4 can be realized. By simply changing the direction of the opening 31A according to the direction in which the terminal member 4 is attached or according to the routing of the control cable 1, it is possible to cope with the brackets B provided at various positions, and the manufacture is easy. It is possible to easily maintain the curved state of the outer casing 2 and avoid damage to the terminal member 4.

  Returning to FIGS. 1, 2, and 3 (a) to 3 (c), the curved end side outer holding portion 32 a bent in a substantially U shape has a curved end side outer holding portion 32 a and an outer casing. A first linking portion 35 that extends between the second curved central portion (the central portion of the curved portion of the outer casing 2) CC and the outer support portion 34 that restricts the movement of the CC extends.

By providing the outer support portion 34, the terminal member 4 can be restricted from moving along the axial direction of the outer casing 2 when the terminal member 4 is inserted into the bracket B of the vehicle.

  In the embodiment shown in FIGS. 1, 2, and 3 (a) to 3 (c), the outer support portion 34 further extending from the first linkage portion 35 is linearly formed from the inner side 2 i to the outer side 2 o of the outer casing 2. It has a first outer side support 34a that extends and curves so as to change direction approximately 180 ° at a position beyond the outer side 2o of the outer casing 2, and further extends from the outer side 2o of the outer casing 2 toward the inner side 2i. The first outer side surface support portion 34a is formed so as to restrict the movement of one side surface 2s (the front side surface in FIG. 1) of the outer casing 2 from the outer side 2o to the inner side 2i of the outer casing 2. The outer support portion 34 further extends from the first outer side surface support portion 34a to the other side surface of the outer casing 2 (not shown; the side surface on the back side of the paper surface in FIG. 1 and the side surface opposite to the one side surface 2s). Toward the inner side 2i of the outer casing 2 so as to form a first outer inner support portion 34b.

  From the first outer inner support portion 34b, a second outer side surface support portion 34c that extends linearly from the inner side 2i of the outer casing 2 toward the outer side 2o and restricts the movement of the other side surface of the outer casing 2 is formed. Yes. After extending linearly from the inner side 2i to the outer side 2o of the outer casing 2, the second outer side surface support portion 34c is bent by approximately 90 °, and from the bending end position CE side in the bending center portion CC to the bending center portion CC. It extends linearly toward the terminal member 4 side (downward in FIG. 1), is further bent by approximately 90 °, extends linearly from the outer side 2o of the outer casing 2 toward the inner side 2i, and the second outer side surface support portion 34c is entirely It is substantially C-shaped and restricts the movement of the other side surface of the outer casing.

  From the second outer side surface support portion 34c, a second outer inner side support portion 34d that is curved from the other side surface of the outer casing 2 toward the one side surface 2s is formed. Similarly to the first outer side surface support portion 34a, the second outer inner side support portion 34d extends from the inner side 2i of the outer casing 2 toward the outer side 2o so as to regulate one side surface 2s of the outer casing 2, and 180 A third outer side surface support portion 34e curved so as to change the direction is formed. From the third outer side surface support portion 34e, the second linkage portion 36 extends toward the bending end side outer holding portion 32b provided at the bending end position CE. The second linkage part 36 extends toward an intermediate position between the terminal member side outer holding part 31 and the curved terminal side outer holding part 32b, and further extends beyond the bent position of the first linkage part 35, It bends and extends toward the curved end side outer holding portion 32b.
