The tension generated in the inner cable 20, especially the tension generated in the portion inserted into the cap 40 will be described later. The outer surface of the inner cable 20 may be covered with a film made of synthetic resin or the like.

The outer casing 30 is a flexible member having openings at both ends, and is an elongated tubular member. The inner cable 20 is slidably inserted into the inner space (hollow portion) of the outer casing 30. The outer casing 30 has an opening through which the inner cable 20 can be inserted at one end. The outer casing 30 is configured such that the other end thereof can be connected to the end of the cap 40 described below so that the hollow portion into which the inner cable 20 is inserted communicates with the insertion hole 40h of the cap 40. The inner cable 20 is held in the outer casing 30 so as to be slidable in the axial direction of the outer casing 30. The outer casing 30 protects the inner cable 20 by covering the outer circumference of the inner cable 20.

The outer casing 30 includes, for example, a tubular liner made of synthetic resin, a reinforcing layer made of a metal wire spirally wound around the outer periphery of the liner, and a coating layer covering the outer surface of the reinforcing layer. The outer casing 30 may be a resin tube made of only a coating layer or any other structure as long as it can suppress sliding friction of the inner cable 30 with other members provided on the vehicle body.

The cap 40 is a member that has an insertion hole 40h through which the inner cable 20 is inserted, and is one mode of an inserted member that has an insertion hole through which the cable is inserted.

There is. Further, the cap 40, which is a member to be inserted, protects the cable and slidably fixes the cable to the attachment target through the fixing member. In the present embodiment, one end of the cap 40 is fixed to the end portion of the outer casing 30. The insertion hole 40h is connected to the outer casing 30 so as to communicate with the hollow portion of the outer casing 30. Thereby, the inner cable 20 led out from the end portion of the outer casing 30 is introduced into the insertion hole 40h from one end (outer casing side) of the cap 40 and is led out from the other end. The cap 40 is a tubular member, and has an inner diameter larger than the outer diameter of the inner cable 20 in the hollow portion. The cap 40 of the present embodiment has a first linear portion 41, a curved portion 42, and a second linear portion 43. The first linear portion 41 is a portion on the operation portion side, one end of which is fixed to the end portion of the outer casing 30 and the other end of which is connected to the bending portion 42. The curved portion 42 is a curved portion of the cap 40 and is connected to the other end of the first linear portion 41. At least a part of the inner cable 20 inserted into the insertion hole 40h bends by coming into contact with the inner peripheral surface of the bending portion 42, so that the extending direction of the inner cable 20 is changed. The second linear portion 43 is a portion that is connected to the other end of the bending portion 42 and from which the inner cable 20 whose extending direction is changed is led out. In the present embodiment, since the bending portion 42 is bent at about 90° with respect to the extending direction of the first linear portion 41, the direction in which the first linear portion 41 extends and the second linear portion 43 extend. The direction in which the inner cable 20 extends is changed by approximately 90°, and the extending direction of the inner cable 20 in the hollow portion is changed by approximately 90° on the substantially same plane.

In the following, as shown in FIG. 6, the direction in which the first linear portion 41 extends is the z direction. Further, the direction perpendicular to the plane L1 parallel to both the extending direction of the second linear portion 43 and the z direction is the x direction. The direction perpendicular to the z direction and the x direction is the y direction. In this case, the second linear portion 42 includes the y-direction component and the z-direction component (however, the case where the z-direction component is zero is also included). In each drawing, the x-direction, the y-direction, and the z-direction are indicated by arrows.

As shown in FIGS. 5 and 6, the lock piece 50 is a member that fixes the cap 40, and is one mode of a fixing member to which the inserted member is fixed. In the present embodiment, the lock piece 50 fixes the inserted member to the vehicle body, but is directly attached to the bracket 60 fixed to the vehicle body. As shown in FIGS. 4 and 5, the lock piece 50 has a mounting portion 51, a housing portion 52, an engaging portion 53, and a biasing member 54. The lock piece 50 is integrally formed of resin. However, the lock piece 50 may be formed of a material other than resin such as metal as long as it is a hard member having a hardness that allows the inserted member to be fixed to the vehicle body, and may be formed of a plurality of members. It may be configured.

The attachment portion 51 is a portion fixed to the bracket 60. The bracket 60 is provided with a recess at the edge of the plate-like portion, and a hole is provided near the recess. The mounting portion 51 is provided with a sandwiching portion and a leaf spring-like fitting portion, and the sandwiching portion is provided so as to project from the side of the accommodation portion. When the accommodating portion of the lock piece 50 is inserted into the concave portion of the bracket 60 from its side surface, the nipping portion nips the plate-shaped portion from both sides, and the fitting portion provided in a part of the nipping portion fits into the hole. Then, the lock piece 50 is configured to be engaged with the bracket 60. The method of fixing the mounting portion 51 to the bracket 60 is not limited to the above-described form, and, for example, snap fitting or screwing is used. The mounting portion 51 may be fixed to the bracket 60 by another fixing method, or the mounting portion 51 may be directly fixed to the vehicle body without the bracket 60. .. Further, the vehicle body or the bracket may be a fixing member having at least the housing portion 52 and the engaging portion 53.

The accommodation portion 52 is a portion in which the cap 40 is accommodated. In the present embodiment, the accommodation portion 52 has an inner wall surrounded by an inner space having a shaft, and the shaft extends in the z direction. The inner wall has an opening 520 that is a side opening that communicates the inner space with the outside and extends in the axial direction, and an opening that is an axial side opening so that the inner space communicates with the outside on both axial sides (hereinafter, Shaft opening). The inner wall has a substantially C-shaped cross section orthogonal to the axial direction (z direction) in which the inner space extends. In the present embodiment, the accommodated portion 44, which is a part of the first linear portion 41 of the cap 40, which is one mode of the inserted member, is inserted into the inner space from the opening 520 and accommodated in the accommodation portion 52. It will be.

FIG. 6 is a diagram schematically showing the direction of tension applied to the inner cable 20 inserted into each part of the cap 40 so as to penetrate the insertion hole 40h in the present embodiment. As described above, when the inner cable 20 is routed, tension is applied to the inner cable 20 along the extending direction of the inner cable 20.

For example, as shown in FIG. 6, in the inner cable 20, in the portion P1 that is a portion that extends from the first linear portion 41, the z direction that is the direction in which the inner cable 20 extends from the first linear portion 41. The tension is applied to the inner cable 20 in the direction of the arrow A1 as a direction including the direction component. In addition, at a portion P2 where the inner cable 20 extends from the second linear portion 42, the y direction, which is the direction in which the inner cable 20 extends from the second linear portion 42, is a directional component, and is indicated by an arrow. Tension is applied to the inner cable 20 in the direction A2. Here, in P3, which is a part of the bending portion 42 that is a portion that bends from the z direction to the y direction, the tension applied to the inner cable 20 is applied in the direction along the bending of the bending portion 42. However, as a whole of the inner cable existing in the hollow portion of the curved portion 42, the resultant force of the tension in the arrow A1 direction and the tension in the arrow A2 direction acts on the arrow A3 direction. That is, in at least a part of the curved portion 42, the inner cable 20 comes into contact with the inner peripheral surface of the insertion hole 40h. Therefore, the force including the component in the y direction that is the direction in which the inner cable 20 extends from the second linear portion 42 and the component in the z direction that is the direction in which the inner cable 20 extends from the first linear portion 41 are Since the force including the force is received from the inner cable 20, the cap 40 receives the force of the y-direction component from the inner cable from the inner peripheral surface of the hollow portion. In addition, when the cap 40 and the inner cable 20 are in contact with the first linear portion 41 or the second linear portion 42 on the inner peripheral surface in addition to the curved portion 42, the cap 40 is, of course, The force including the y-direction component and the force including the z-direction component are received from the inner cable 20.

As described above, in the present embodiment, the cap 40 receives the force including the y-direction component and the force including the z-direction component from the inner cable 20, and thus includes the y-direction component shown in FIG. 6. Since the force in the arrow A4 direction is received, the accommodated portion provided in the first linear portion 41 also receives the force in the arrow A4 direction component from the inner cable 20.

As shown in FIG. 4, the housing portion 52 of the lock piece 50 has an opening 520 opened in the −x direction, which is a direction perpendicular to the extending direction of the housing portion 52. Further, the opening 520 is a direction that is perpendicular to the direction z in which the accommodated portion 44 extends and that intersects with the direction in which the tension applied to the accommodated portion 44 is applied (here, -x). Direction), the accommodated portion 44 is provided so as to be accommodated in the accommodation portion 52. The accommodated portion 44 of the cap 40 is accommodated in the accommodation portion 52 by being inserted in the +x direction with respect to the opening 520. Further, the opening 520 intersects with the direction of the tension indicated by the broken line arrow A4 in FIG. 6 among the directions (all the directions parallel to the xy plane) perpendicular to the direction in which the accommodated portion 44 extends. It is opened in the (-x direction in this embodiment).

The engagement portion 53 engages with the cap 40, which is an example of the inserted member, in the lock piece 50, which is an example of the fixing member. When the inner cable 20 is routed and tension is applied, the engagement portion 53 is on the side of the direction (y direction) perpendicular to the direction in which the accommodated portion 44 extends, in the direction in which tension is applied. At least it is provided so as to face the engaged portion 45. Here, as shown in FIG. 4, the engagement portion 53 is provided on the inner peripheral surface of the accommodation portion 52. On the other hand, as shown in FIG. 2, the cap 40 has an engaged portion 45 that engages with the engaging portion 53. The engaged portion 45 is provided on the outer peripheral surface of the accommodated portion 44, and is provided at a position facing the engaging portion 53. In the present embodiment, the engaging portion 53 and the engaged portion 45 are configured by screw grooves and screw threads that mesh with each other. The screw groove and the screw thread are provided so as to intersect with the z direction in which the first linear portion 41 extends. The engaging portion 53 and the engaged portion 45 prevent the cap 40 from coming off from the housing portion 53 due to the engaging force generated by engaging with each other. While the cap 40 is attached to the lock piece 50, the engaging portion 53 and the engaged portion 45 engage with each other, but tension is applied to the inner cable 20 inserted through the insertion hole 40h. Then, as described above, the force in the arrow A4 direction shown in FIG. 6 is applied to the cap 40. That is, the cap 40 is applied with a force to incline in the arrow A4 direction with respect to the axial direction of the housing portion. Therefore, the engaged portion 45 is pressed against the engaging portion 53, so that it can be engaged more strongly. The cap 40 is not only prevented from being separated from the accommodating portion 53 by the opening provided in the axial direction (z direction) of the accommodating portion 53 due to the frictional force generated by the above-described engagement, but also the cap 40 Detachment from the opening 520 that opens in the direction perpendicular to the axial direction (x direction) is also suppressed.

In the cap 40, by the force applied by the tension of the inner cable 20, the engaged portion 45 provided in the accommodated portion 45 and the engaging portion 53 provided in the accommodating portion 52 are strongly engaged, Detachment from the accommodation section is suppressed. Therefore, the engaging portion 53 and the engaged portion 45 are at least parts where the force applied by the tension of the inner cable 20 acts and the engaged portion 45 is pressed against the engaging portion, It suffices that the cap 40 is provided so as to generate an engaging force that is restrained from being detached from the accommodating portion. That is, at least a part of the engaging portion 53 and the engaged portion 45 is a direction perpendicular to the extending direction (z direction) of the accommodated portion 45 in the direction in which the tension from the inner cable 20 is applied. It is provided on the side of the component direction (y direction). At this time, in order to suppress the detachment of the cap 40, the engaging portion 53 is given a tension from the inner cable 20 in order to make the engaging force between the engaging portion 53 and the engaged portion 45 stronger. Among the directions, it can be arranged so as to be opposed to each other on the axis of the direction component (y direction) perpendicular to the extending direction (z direction) of the accommodated portion 45 with the axis of the accommodating portion 52 interposed therebetween. .. That is, when the accommodated portion 44 is accommodated in the accommodating portion 52, the engaging portion 53 and the engaged portion 45 are engaged with each other, and as described above, the component of the force for moving the cap 40 is Since the component parallel to the z direction is included, even if the cap 40 tries to move via the inner cable 20 in the z direction due to the contact between the inner cable 20 and the inner peripheral surface of the curved portion 42, the screw groove and the screw thread are separated from each other. The movement of the cap 40 is restricted by the engagement. In this way, axial displacement of the accommodated portion 44 with respect to the accommodating portion 52 is suppressed.

The engaging portion 53 and the engaged portion 45 are not limited to the thread groove and the screw thread, and both the extending direction of the concave portion and the extending direction of the convex portion intersect the extending direction of the first linear portion 41. It may be another uneven structure provided. For example, the engaging portion 53 may be a plurality of convex portions, and the engaged portion 45 may be a plurality of concave portions that engage with the convex portion. Further, the engaging portion 53 may be a plurality of concave portions, and the engaged portion 45 may be a plurality of convex portions that engage with the concave portion.

In the present embodiment, the concavo-convex structure in the engaging portion 53 and the engaged portion 45 is a spiral thread groove and a screw thread. Therefore, the concavo-convex structure has an angle with respect to the extending direction (z direction) of the engaging portion 53 and the engaged portion 45. That is, when the inner cable 20 is routed and tension is applied, the engagement portion 53 is perpendicular to the direction in which the accommodated portion 44 extends (z direction) in the direction in which tension is applied (yz direction). It is provided at least so as to face the engaged portion 44 on the side of the direction component (direction component in any direction along the xy plane). In short, the engagement between the engaging portion 53 and the engaged portion 45 is a component perpendicular to the z direction in which the accommodated portion 44 extends so that movement in a direction non-parallel to the z direction is restricted. The direction of should be included. Therefore, it includes a case where it is not provided in the direction perpendicular to the z direction like the above-mentioned screw groove and screw thread.

As described above, it is possible to suppress the accommodation portion 44 from dropping from the accommodation portion 52 due to the tension of the inner cable 20.

In the present embodiment, the direction in which the accommodation portion 52 is accommodated in the accommodation portion 44 is perpendicular to the direction of the tension indicated by the dashed arrow A4, but the direction in which the accommodation portion 52 is accommodated in the accommodation portion 44. Does not have to be vertical. The direction in which the accommodating portion 52 is accommodated in the accommodated portion 44 may be a direction that is non-parallel to the direction of the tension indicated by the broken line arrow A4 among the directions perpendicular to the extending direction of the accommodated portion 44. .. This is because if the wall surface of the housing portion 52 exists in a direction that is non-parallel to the direction of the tension indicated by the broken line arrow A4, the wall surface of the housing portion 52 functions as a stop for restricting the movement in the y direction. The accommodating portion 53 connects, as a schematic shape, two plate-shaped portions that are parallel to each other and the end of the plate-shaped portion in the same direction side (+x side in FIG. 4) and on the side opposite to the plate-shaped portion. It is composed of a convex plate-shaped curved portion. The two plate-shaped portions have an interval of substantially the same length as the outer diameter of the cap 40, and the curved portion has a radius of curvature substantially the same as the radius of the outer circumference of the cap 40. Since the cap 40 and the lock piece 50 have such a dimensional relationship, the cap 40 fits the lock piece 50, and the engagement by the tension applied to the inner cable 20 can be easily obtained. In addition, the cap 40 is provided with the curved portions 42 that project the first linear portions from the openings on both sides in the axial direction of the accommodating portion 53 and change the direction of the tension, and the first linear portion that projects longer A curved portion 42 is provided at the end of the portion. By doing so, the engagement force between the cap 40 and the lock piece 50 can be increased.

The biasing member 54 is a member provided on the lock piece 50 that is a fixing member. The urging member 54 maintains the accommodation of the accommodated portion 44 in the accommodation portion 54, is a directional component perpendicular to the extending direction of the accommodated portion 44, and is a member to be inserted from a direction intersecting with a direction in which tension is applied. When the external force is applied to the cap 40, the member 40 is a member for urging the cap 40, which is the inserted member, so as to allow the housed portion 44 to be separated from the housing portion 54. As shown in FIGS. 4 and 5, the biasing member 54 has two legs 541 extending in the −x direction from the edge of the opening 520, and extends from the tips of the legs 541 toward the center of the opening 520. And a claw portion 542.

As described above, a force that moves the cap 40 in the x direction may be applied. When an external force is applied to the to-be-accommodated portion 44 of the cap 40 in a direction of separating from the to-be-accommodated portion 52 (-x direction), the to-be-accommodated portion 44 tries to move in the -x direction. The surface comes into contact with the tip of the claw portion 542 and serves as a stop. As a result, the accommodation portion 44 is prevented from being separated from the accommodation portion 52, and the accommodation of the accommodation portion 44 in the accommodation portion 52 is maintained in the stationary state.

On the other hand, when it is desired to remove the cap 40 from the lock piece 50, an external force is applied to the claw portions 542 in the directions of arrows A7 and A8 in FIG. 5 to bend the pair of claw portions 542 outward and The interval of 542 in the y direction is increased to be equal to or larger than the outer diameter of the cap 40. Thereby, the accommodated portion 44 can be taken out from the opening 520. In other words, the biasing member 54 has a function of temporarily fixing the cap 40 to the lock piece 50 and applying tension to the inner cable 20, so if the tension is not applied, the lock piece 50 is not locked. The cap 40 can be easily removed from the.

In this embodiment, the direction of the external force applied when it is desired to remove the cap 40 from the lock piece 50 is the direction including the +x direction and the -y direction indicated by the arrow A7 and the +x direction and the +y direction indicated by the arrow A8. It is a direction including. As described above, when the cap 40 is removed, the direction in which the external force is applied to the claw portion 542 is the direction component perpendicular to the direction in which the accommodated portion 44 extends, and the direction intersecting the direction of the tension indicated by the dashed arrow A4. Preferably. This is because the tension of the broken line arrow A4 can prevent the claw portion 542 from bending. Therefore, it is possible to suppress the accommodation portion 44 from being separated from the opening 520 by the tension of the broken line arrow A4.

In the present embodiment, the cap 40 has the two linear portions 41 and 43 and the curved portion 42 as described above. As in the present embodiment, when there is a portion where the cable is bent and installed, and when a member to be inserted is provided around the bent portion or the bent portion, when a fixing member for fixing the cable is attached, As described above, the inserted member easily falls off from the fixed member due to the tension of the cable. That is, when the cap 40 is formed in an L shape, the tension of the inner cable 20 tends to apply a force between the cap 40 and the lock piece 50 in a direction intersecting with the extending direction of the accommodated portion 44. Therefore, the cap 40 is more likely to fall off the lock piece 50 than when the cap 40 is composed of only the linear portion.

However, in the cable routing structure 1, even if the cap 40 has the curved portion 42, the cap 40 is unlikely to be separated from the lock piece 50 due to the tension of the inner cable 20 as described above. Therefore, it is possible to prevent the cap 40 from falling off the lock piece 50. On the other hand, according to the cable routing structure 1, the cap 40 can be easily removed from the lock piece 50 by the biasing member 54 described above. In this way, the movement in the axial direction and the drop from the lock piece 50 can be suppressed.

Further, in the cable routing structure of the present invention, the accommodated portion may have a flat portion, and the biasing member may bias the flat portion from the opening. For example, as shown in FIG. 3, in the present embodiment, the cap 40 having the accommodated portion 44 has the flat portion 441 on a part of the outer peripheral surface of the accommodated portion 44. The cap 40 is housed in the housing part 52 such that the flat part 441 faces the opening 520 (−x direction). Then, the tip of the biasing member 54 contacts the flat portion 441 from the opening 520 side to bias the flat portion 441. Therefore, as compared with the case where the biasing member 54 contacts the curved surface portion of the cap 40, the cap 40 is prevented from rotating about the extending direction of the first linear portion. Therefore, the cap 40 can be held more reliably by the biasing member 54.

Further, if the flat portion 441 is formed on the cap 40, the mounting direction of the cap 40 can be easily understood. Therefore, when it is necessary to attach the cap 40 to the lock piece 50 in the same direction when manufacturing the cable routing structure 1, the work of attaching the cap 40 to the lock piece 50 can be easily performed. In the present embodiment, when the cap 40 is attached in a posture in which the flat portion 441 faces the −x direction, the second linear portion 43 faces the +y direction.

Although one embodiment of the present invention has been described above, the present invention is not limited to the above embodiment.

In the above-described embodiment, the bending portion of the insertion member is bent at a substantially right angle, but the bending angle of the bending portion may be an acute angle or an obtuse angle.

Further, in the above embodiment, the cap has the linear portion and the curved portion, but the cap may be configured by only the linear portion, or may be configured by only the curved portion. ..

Further, in the above-mentioned embodiment, the cable routing structure has the outer casing, but the outer casing may not be provided.

Further, in the above embodiment, the engaging portion is provided on the inner peripheral surface of the housing portion of the fixing member, but the engaging portion may be provided at a position different from the housing portion.

Further, the detailed shape of each member may be different from the shape shown in each drawing. Moreover, you may combine suitably each said element in the range which does not produce inconsistency.
