Has been. Each rotationally symmetric axis is opposed to each other over the entire circumference in a state in which the respective axes of rotational symmetry are inclined with respect to the respective axial directions of the first cylindrical member and the second cylindrical member.

On the other hand, a plurality of recesses are formed in which the plurality of protrusions are inserted in the projecting direction and can be fitted. The first end and the second end are fixed to each other by fitting each of the plurality of protrusions into the corresponding recess among the plurality of recesses. Therefore, by changing the relative positional relationship between the plurality of protrusions and the plurality of recesses in various ways, the bending angle of the protector can be changed variously, and the fluctuation of each bending angle can be changed. It can be strongly regulated.

  According to the sixth aspect of the invention, the plurality of protrusions have two or more rotational symmetry with respect to the rotation axis of the second contact portion. Therefore, if the plurality of recesses have the same rotational symmetry as the plurality of protrusions with respect to the rotation axis, the rotation angle of the second contact portion with respect to the first contact portion can be adjusted, thereby allowing a plurality of different mutually At the rotation angle, the plurality of protrusions can be fitted into the plurality of recesses. Therefore, the increase in the number of the plurality of protrusions and the plurality of recesses can be suppressed, the structure of the first end and the second end can be simplified, and the manufacturing cost of the protector can be reduced.

  According to the seventh aspect of the invention, the outer peripheral side surface of the first end portion and the inner peripheral side surface of the second end portion have two or more rotational symmetries, and face each other over the entire circumference. It is formed in a possible shape. Each of the plurality of protrusions is provided in a rotationally symmetrical manner with respect to a rotational symmetry axis at a certain rotational angle. The plurality of relative positional relationships are the positional relationships when the second abutting portion is rotated with respect to the first abutting portion about the rotational symmetry axis for each of the predetermined rotation angles. The inner peripheral side surface is formed in a shape that can be opposed to each other over the entire circumference in any of a plurality of relative positional relationships. Therefore, it is possible to easily fit the plurality of protrusions to the plurality of concave portions while bringing the outer peripheral side surface and the inner peripheral side surface into contact with each other regardless of the bending angles of the protectors according to the plurality of relative positional relationships. it can.

  According to the eighth aspect of the invention, the first contact portion is the outer peripheral side surface of the first end portion, and the second contact portion is the inner peripheral side surface of the second end portion. A plurality of protrusions are formed on one side surface of the peripheral side surface, and a plurality of recesses are formed on the other side surface. Therefore, the first contact portion and the second contact portion are firmly in contact with each other by fitting the plurality of protrusions and the plurality of recesses formed directly on the first contact portion and the second contact portion. Is done. Further, the relative movement in the radial direction between the first contact portion and the second contact portion can also be restricted by the contact itself between the first contact portion and the second contact portion. Thereby, a 1st end part and a 2nd end part can be fixed more firmly, and the fluctuation | variation of the bending angle of a protector can be controlled more strongly.

  According to the ninth aspect of the invention, each of the plurality of recesses is a through-hole penetrating the wall surface on which the plurality of recesses are formed, and each of the plurality of protrusions corresponds to the plurality of recesses. It penetrates and fits into each recess. Therefore, since the contact portion between the projection and the recess can be increased, the first end and the second end can be more firmly fixed.

  According to the eleventh aspect of the invention, the first cylindrical member has a cross-sectional shape perpendicular to the axial direction of the main body portion other than the first end portion, and the second cylindrical member has a main body other than the second end portion. Since the cross-sectional shape perpendicular to the axial direction of each part is an ellipse, the cross-sectional shape at a predetermined angle oblique to the axial direction can be made circular. Accordingly, the main body portion having an elliptical cross section and the end portion having a circular cross section can be smoothly connected.

  According to the twelfth aspect of the invention, the first flange portion formed over the entire circumferential direction of the first end portion is formed over the entire circumferential direction of the second end portion. The first end and the second end are fixed to each other by fitting into the recess of the two flanges. In this state, the respective rotational symmetry axes of the outer peripheral end surface of the first flange portion and the bottom surface of the hollow portion and the rotational shaft of the bottom surface are the axial directions of the first cylindrical member and the second cylindrical member, respectively. The outer peripheral end face and the bottom face each other over the entire circumference. Therefore, regardless of the rotation angle of the bottom surface with respect to the outer peripheral end surface, the outer peripheral end surface and the bottom surface can be easily brought into contact with each other. Thereby, the 1st end part and the 2nd end part can be firmly fixed, suppressing the change of the relative positional relationship of an outer peripheral end surface and a bottom face, ie, the change of the bending angle of a protector.

  According to the thirteenth aspect of the invention, the outer peripheral end surface (first contact portion) of the first flange portion is formed in a regular polygonal shape having rotational symmetry with respect to the rotational symmetry axis. Further, the bottom surface (second contact portion) of the hollow portion of the second flange portion is formed in a shape that can be opposed to the outer peripheral end surface over the entire circumference. Therefore, since the movement of the bottom surface of the hollow portion of the second flange portion with respect to the outer peripheral end surface of the first flange portion can be more reliably restricted, fluctuations in the bending angle of the protector can be further restricted.

  According to the fourteenth aspect of the present invention, the angle of the extending direction of the first abutting portion with respect to the axial direction of the first cylindrical member and the extending of the second abutting portion with respect to the axial direction of the second cylindrical member. The direction angles are the same as each other. Therefore, since the first end portion and the second end portion can be fixed while the axial direction of the first cylindrical member and the axial direction of the second cylindrical member are made the same direction, the first cylindrical member and the second cylindrical portion can be fixed. The shape of the cylindrical body formed by the cylindrical member, that is, the shape of the protector can be not only a bent shape but also a linear shape.

  According to the fifteenth aspect of the invention, the angle of the extending direction of the first contact portion with respect to the axial direction of the first tubular member and the extension of the second contact portion with respect to the axial direction of the second tubular member. Each direction angle is 45 degrees. Therefore, the angle of the second cylindrical member in the axial direction relative to the axial direction of the first cylindrical member, that is, the bending angle of the protector can be set to an angle in the range of 0 to 90 degrees. Therefore, the path of the wire harness that is bent and arranged at various angles can be regulated.

  According to the sixteenth aspect, at least one of the first tubular member and the second tubular member is formed in each shape obtained by dividing the tubular member into a plurality of portions in the circumferential direction. A plurality of members are combined members fixed so as to form a cylindrical body. Therefore, since the wire harness can be routed with respect to at least one of the first tubular member and the second tubular member in a state where the tubular member is not closed, the routing operation is facilitated. In addition, for example, the first end and the second end can be fixed by a fitting structure including a protrusion and a recess provided in the radial direction of the cylindrical member. Can be fixed more firmly.

<Embodiment 1>
The protector 100A according to the first embodiment is configured to include a first cylindrical member 11 and a second cylindrical member 12 that are each formed of resin or the like. The first end 21 on one end side of the first tubular member 11 is inclined (in the direction of the arrow K1) with respect to the axis L1 direction (longitudinal direction, wiring direction of the wire harness) of the first tubular member 11. An outer peripheral side surface (“first contact portion”) 31 extending in a band shape is provided. The second end portion 22 on the other end side of the first end portion 21 has an oblique direction (arrow K1 direction) with respect to the axis L2 direction (longitudinal direction, wiring direction of the wire harness) of the second tubular member 12. An inner peripheral side surface (“second contact portion”) 32 extending in a belt shape is provided. In the protector 100 </ b> A, the first cylindrical member 11 and the second cylindrical member 12 are in the form of one cylindrical body in which the respective internal spaces communicate with each other with the outer peripheral side surface 31 and the inner peripheral side surface 32 in contact with each other. The first end 21 and the second end 22 are fixed to each other so as to form (see FIGS. 1 to 3). The wire harness W is inserted through the protector 100A and the path is restricted. The protector 100A and the wire harness W inserted through the protector 100A are wire harnesses with protectors.

  If the rotation angle (rotation posture) of the second end portion 22 along the circumferential direction of the second end portion 22 is changed with respect to the outer peripheral side surface 31, the bending angle of the second cylindrical member 12 with respect to the first cylindrical member 11 And the bending direction can be changed. Therefore, by adjusting the rotation angle of the second end portion 22 according to the bent path of the wired wiring harness and fixing the first end portion and the second end portion, an increase in the type of protector is suppressed. On the other hand, it is possible to regulate the route of the wire harness that is bent and arranged at various angles.

  More specifically, the outer peripheral side surface 31 and the inner peripheral side surface 32 are common rotations inclined with respect to the axis L1 direction of the first cylindrical member 11 and the axis L2 direction of the second cylindrical member 12 respectively. Each has two or more rotational symmetries with respect to the symmetry axis L3, and is formed into a shape that can be opposed to each other over the entire circumference, such as a shape that can overlap each other. Then, the outer peripheral side surface 31 and the inner peripheral side surface 32 are aligned with each other so that the respective rotational symmetry axes L3 are inclined with respect to the respective axis L1 and L2 directions of the first cylindrical member 11 and the second cylindrical member 12. In this state, they are opposed to each other over the entire circumference. The direction of the arrow K1 oblique to the direction of the axis L1 (L2) of the first cylindrical member 11 (second cylindrical member 12) is a direction orthogonal to the direction of the rotational symmetry axis L3.

  The outer peripheral side surface 31 is formed in a cylindrical shape with the rotational symmetry axis L3 as the central axis, and the inner peripheral side surface 32 is formed on the entire circumference with the outer peripheral side surface 31 such as an inverted shape of the outer peripheral side surface 31. In other words, they are formed in shapes that can face each other. Therefore, the outer peripheral side surface 31 and the inner peripheral side surface 32 are each circular. More specifically, each of the outer peripheral side surface 31 and the inner peripheral side surface 32 has a circular cross-sectional shape perpendicular to the rotational symmetry axis L3. As described above, the outer peripheral side surface 31 and the inner peripheral side surface 32 are shaped so that the shape of the one-sided irregularities turned upside down and the other shape are the same shape, that is, the shape viewed from the back side, The other is formed so as to have the same shape as viewed from the front side.

  In addition, each shape of the outer peripheral side surface 31 and the inner peripheral side surface 32, that is, the cross-sectional shape perpendicular to each rotational symmetry axis L3 is not limited to a circle, and if it is a shape having two or more rotational symmetry, For example, it may be a regular polygon such as a regular octagon. In addition, the outer peripheral side surface 31 and the inner peripheral side surface 32 are formed in a rotationally symmetric shape with no hidden portions when the respective portions of the side surfaces are viewed directly across the entire circumference toward the rotational symmetry axis L3. ing. In other words, the outer peripheral side surface 31 and the inner peripheral side surface 32 are defined by the line segments connecting the respective viewpoints and the legs of the perpendicular line extending from the respective viewpoints on the rotational symmetry axis L3. It is formed in a rotationally symmetrical shape that intersects with each one only once. Even if the shape of the inner peripheral side surface 32 is different from the shape in which the uneven shape of the outer peripheral side surface 31 is turned upside down, and even if at least one of the outer peripheral side surface 31 and the inner peripheral side surface 32 is not rotationally symmetric, Since the 1st end part 21 and the 2nd end part 22 can be fixed by bending the inner peripheral side surface 32 and overlapping, the usefulness of this invention is not impaired.

  The first end portion 21 and the second end portion 22 are formed so as to be fixable to each other in a plurality of different relative positional relationships. In each of the plurality of relative positional relationships, the rotation angle θ (see FIG. 3) of the inner peripheral side surface 32 with the rotation axis R3 as the rotation center with respect to the outer peripheral side surface 31, that is, the inner side along the circumferential direction of the second end portion 22 The rotation angles θ of the peripheral side surfaces 32 are different from each other. The rotation axis R3 coincides with the rotational symmetry axis L3. In addition, each of the plurality of relative positional relationships includes, for example, a positional relationship in which the outer peripheral side surface 31 and the inner peripheral side surface 32 can overlap each other. It is also a positional relationship that can be opposed.

  Specifically, the outer peripheral side surface 31 is formed with a plurality of protrusions 41 projecting toward the inner peripheral side surface 32 along a direction different from the rotation axis R3 of the inner peripheral side surface 32. Each protrusion 41 is formed in, for example, a quadrangular prism shape and is formed integrally with the outer peripheral side surface 31.

  Each protrusion 41 can be inserted into and fitted in the inner peripheral side surface 32 in each of a plurality of relative positional relationships between the outer peripheral side surface 31 and the inner peripheral side surface 32 having different rotation angles θ. A plurality of concave portions 42 are formed. The side wall shape of the recess 42 is formed in a shape in which the unevenness of the side surface shape of the protrusion 41 is turned upside down. When the protrusion 41 is fitted into the recess 42, the relative positional relationship between the protrusion 41 and the recess 42 changes in the circumferential direction (arrow S1 direction) of the inner peripheral side surface 32 and the rotation axis R3 direction. Is regulated in

  Each recess 42 is a through-hole penetrating the wall surface of the second end portion 22 in which each recess 42 is formed, and each protrusion 41 is connected to a corresponding protrusion of each recess 42 from the inner peripheral side surface 32 side. Inserted and mated. The tip of each protrusion 41 penetrates through each recess 42 and protrudes outward from the outer peripheral side surface of the second end 22. Thereby, the projection 41 can be firmly fitted into the recess 42. In addition, the recessed part 42 is a hollow part which is provided with a bottom part and is not a through-hole, and the protrusion part 41 is accommodated in the recessed part 42 in a state where the outer peripheral side surface 31 and the inner peripheral side surface 32 face each other over the entire circumference. Accordingly, the protrusion 41 may be fitted into the recess 42.

  The outer peripheral side surface 31 is in a state where the outer peripheral side surface 31 and the inner peripheral side surface 32 face each other over the entire circumference in one relative positional relationship among a plurality of relative positional relationships in which the rotation angles θ are different from each other. Variation of the rotation angle θ about the rotation axis R3 in the circumferential direction (arrow S1 direction) of the inner peripheral side surface 32 with respect to the movement, and movement of the inner peripheral side surface 32 relative to the outer peripheral side surface 31 along the rotation axis R3 direction (rotation symmetry axis) The protrusions 41 are fitted in the corresponding recesses 42 of the recesses 42 so as to restrict the movement in the L3 direction. Thereby, the 1st end part 21 and the 2nd end part 22 are mutually fixed. Each protrusion 41 formed on the outer peripheral side surface 31 has a rotational symmetry of two or more times with respect to the rotation axis R3. In other words, each of the protrusions 41 is provided in a rotationally symmetrical manner for each fixed rotation angle with respect to the rotation axis R3. The relative positional relationship between the outer peripheral side surface 31 and the inner peripheral side surface 32 when the first end portion 21 and the second end portion 22 are fixed to each other is such that the inner peripheral side surface 32 is the rotation axis R3, that is, the rotational symmetry axis L3. , And the positional relationship when the outer peripheral side surface 31 is rotated at each fixed rotation angle. The outer peripheral side surface 31 and the inner peripheral side surface 32 are formed in shapes that can face each other over the entire circumference in any of the relative positional relationships.

  A plurality of protrusions may be formed on the inner peripheral side surface 32 so as to protrude toward the outer peripheral side surface 31, and a plurality of recesses corresponding to the plurality of protrusions may be formed on the outer peripheral side surface 31. That is, a plurality of protrusions are formed on one side surface of the outer peripheral side surface 31 and the inner peripheral side surface 32 so as to project toward the other side surface along a direction different from the common rotational symmetry axis L3. Yes. On the other side surface, a plurality of recesses are formed in which a plurality of protrusions can be inserted and fitted in the projecting direction. The plurality of protrusions can be fitted into the plurality of recesses in each of a plurality of relative positional relationships between the outer peripheral side surface 31 and the inner peripheral side surface 32, and the plurality of relative positional relationships are represented by the rotational symmetry axis L <b> 3. The rotation angle θ of the inner peripheral side surface 32 with respect to the outer peripheral side surface 31 is different from each other, and the outer peripheral side surface 31 and the inner peripheral side surface 32 can be overlapped with each other. In addition, each projection 41 (or each recess 42) is formed in a portion other than the outer peripheral side surface 31 in the first end portion 21, and each recess 42 (or in each portion other than the inner peripheral side surface 32 in the second end portion 22. Each protrusion 41) may be formed.

  Further, when the rotation axis R3 related to the rotation of the inner peripheral side surface 32 along the circumferential direction of the second end portion 22 is different from the rotational symmetry axis L3, the outer peripheral side surface 31 and the inner peripheral side surface 32 are the same rotationally symmetrical shape. Even if, the outer peripheral side surface 31 and the inner peripheral side surface 32 usually do not completely overlap. However, the first end portion 21 and the second end portion 22 can be fixed by bending the inner peripheral side surface 32 and overlapping the outer peripheral side surface 31. Therefore, even if the rotation axis R3 is different from the rotational symmetry axis L3, the usefulness of the present invention is not impaired. That is, the first end portion 21 and the second end portion 22 are different from the rotation axis R3 (rotation symmetry axis L3 or rotation symmetry axis L3) of the inner peripheral side surface 32 along the circumferential direction of the second end portion 22. In each of a plurality of relative positional relationships in which the rotation angle θ about the axis) differs from the outer peripheral side surface 31, the rotation angles θ are formed to be fixed to each other.

  The first cylindrical member 11 is a combination member in which a bowl-shaped first lid member 11a and a bowl-shaped first housing member 11b are combined and fixed, and the second cylinder member 12 is a bowl-shaped member. This is a combination member in which the second lid member 12a and the bowl-shaped second housing member 12b are combined and fixed (see FIGS. 1 and 4 to 7). The 1st cover member 11a and the 1st accommodating member 11b are each formed in each shape which divided | segmented the 1st cylindrical member 11 into two in the circumferential direction. Moreover, the 2nd cover member 12a and the 2nd accommodating member 12b are formed in each shape which divided | segmented the 2nd cylindrical member 12 into two in the circumferential direction.

  On one side wall of the pair of side walls of the first lid member 11a, a plurality of locking pieces 132 each having a locking claw at the tip are provided. Among the pair of side walls of the first housing member 11b, a plurality of locking frames 131 each having a locking hole are provided on one side wall that is overlapped with one side wall of the first lid member 11a. The locking piece 132 is inserted into the locking hole from one side of the locking frame 131, the locking claw protrudes to the other side, and is locked to the locking frame 131, so that the locking piece 132 is attached to the locking frame 131. Lock. Similarly, a plurality of locking frames 131 are provided on the other side wall of the first lid member 11a, and a plurality of locking pieces 132 are provided on the other side wall of the first housing member 11b. And each side wall of the 1st cover member 11a and the 1st accommodating member 11b is piled up, and the latching of each latching piece 132 provided in the 1st lid member 11a and the 1st accommodating member 11b is carried out. The claw is locked to each locking frame 131. Thereby, the 1st cover member 11a and the 1st accommodating member 11b are mutually fixed, and the 1st cylindrical member 11 is formed.

  Similarly, a plurality of locking frames 131 and locking pieces 132 are provided on the pair of side walls of the second lid member 12a, respectively, and the locking frame 131 and the locking pieces are also provided on the pair of side walls of the second housing member 12b. 132 are provided. Then, the side walls of the second lid member 12a and the second housing member 12b are overlapped with each other, and the locking claws of the locking pieces 132 are locked to the locking frames 131, whereby the second lid member 12a. And the second housing member 12b are fixed to each other to form the second tubular member 12.

  If at least 2nd cylindrical member 12 is a combination member among 1st cylindrical member 11 and 2nd cylindrical member 12, the inner peripheral side surface with respect to the outer peripheral side surface 31 of the 1st cylindrical member 11 in which the wire harness was penetrated The second cylindrical member 12a and the second accommodating member 12b are separately separated from the outside toward the axial direction of the first cylindrical member 11 so that the relative positional relationship of 32 becomes a desired positional relationship. 11 can be easily attached to each of the recesses 42. In addition, even when only the 1st cylindrical member 11 is a combination member among the 1st cylindrical members 11 and the 2nd cylindrical members 12, for example, the 2nd end part 22 of the 2nd cylindrical member 12 is possible. If it is formed of a highly flexible resin or the like, the first lid member 11a and the first lid 11a are connected to the first cylindrical member 12 while expanding the second end 22 of the second cylindrical member 12 outward from the inner space side of the second cylindrical member 12. The projections 41 can be fitted into the recesses 42 by forcing the accommodation member 11b separately in the direction of the rotational symmetry axis L3.

  Further, the first cylindrical member 11 (second cylindrical member 12) is combined so that a plurality of members each having a shape that is divided into three or more along the circumferential direction form a cylindrical body. Then, the first cylindrical member 11 (second cylindrical member 12) may be formed by being fixed. That is, at least one cylindrical member of the first cylindrical member 11 and the second cylindrical member 12 has a plurality of members formed in respective shapes obtained by dividing the cylindrical member into a plurality of circumferential directions. The combination member is combined and fixed so as to form a cylindrical body. In addition, even if both the 1st cylindrical member 11 and the 2nd cylindrical member 12 are integrally formed, while extending the 2nd end part 22 of the 2nd cylindrical member 12, 1st cylindrical shape By forcibly inserting the member 11 in the direction of the rotational symmetry axis L3, each projection 41 can be fitted into each recess 42, so that the usefulness of the present invention is not impaired.

  In the protectors 100A1 to 100A4 (see FIG. 8), the above-described relative positional relationships between the outer peripheral side surface 31 of the first cylindrical member 11 and the inner peripheral side surface 32 of the second cylindrical member 12 are different from each other. That is, in the protectors 100A1 to 100A4, the rotation angle θ of the inner peripheral side surface 32 with respect to the rotation axis R3 (rotation symmetry axis L3) is different from the outer peripheral side surface 31. And the extending direction (arrow K1 direction) of the outer peripheral side surface 31 and the inner peripheral side surface 32 is inclined with respect to the axis L1 (L2) of the first cylindrical member 11 (second cylindrical member 12). A rotationally symmetric axis L3 perpendicular to the extending direction is also inclined with respect to the axis L1 (L2). Therefore, as shown in FIG. 8, the protector 100 </ b> A changes the relative positional relationship described above between the outer peripheral side surface 31 of the first cylindrical member 11 and the inner peripheral side surface 32 of the second cylindrical member 12. By fixing the first end 21 and the second end 22 to each other, the bending angle of the second cylindrical member 12 with respect to the first cylindrical member 11 can be changed. Further, when the bending angle is different, the bending direction is also different. That is, the protector 100A can change the bending angle three-dimensionally.

  Further, an angle (an included angle) a1 in the extending direction (arrow K1 direction) of the outer peripheral side surface 31 with respect to the axis L1 direction of the first cylindrical member 11 and the inner peripheral side surface 32 of the second cylindrical member 12 with respect to the axis L2 direction. It is formed so that the angle (the included angle) a2 in the extending direction (arrow K1 direction) is the same angle (see FIG. 2). Thus, if the angle a1 and the angle a2 are the same angle, adjusting the positional relationship of the second end portion 22 with respect to the first end portion 21 makes the axis L1 direction and the axis L2 direction the same direction. The first end 21 and the second end 22 can be fixed to each other. Thereby, the shape of the protector 100A formed by the first tubular member 11 and the second tubular member 12 can be not only a bent shape but also a linear shape.

  Further, if the angle a1 and the angle a2 are 45 degrees with respect to each other, the angle in the axis L2 direction with respect to the axis L1 direction, that is, the bending angle of the protector 100A can be set to an angle in the range of 0 degree to 90 degrees. Therefore, the path of the wire harness inserted through the protector 100A can be restricted with more bending angles. Even if the angle a1 and the angle a2 are different from each other, the bending angle between the first cylindrical member 11 and the second cylindrical member 12 can be changed by changing the rotation angle θ of the inner peripheral side surface 32 with respect to the outer peripheral side surface 31. Since it can be changed, the usefulness of the present invention is not impaired.

  A cross-sectional shape perpendicular to the axis L1 direction of the main body portion other than the first end portion 21 in the first cylindrical member 11 and an axial L2 direction of the main body portion other than the second end portion 22 of the second cylindrical member 12. Each vertical cross-sectional shape is formed in an elliptical shape. Here, when the elliptical cylinder is cut in an oblique direction with respect to the axial direction, the shape of the cut end can be made circular by setting the cutting angle to a specific angle. Therefore, in the protector 100A, the rotational symmetry axis L3 is orthogonal to the oblique cut surface in which the cross-sectional shape of the oval cylindrical body portion is circular, and the outer peripheral side surface 31 (inner peripheral side surface 32) perpendicular to the rotational symmetry axis L3. If the first end portion 21 (second end portion 22) is formed so that the cross-sectional shape of the main body portion matches the circular outer peripheral shape, the cross-sectional shape perpendicular to the axis L1 direction of the main body portion is constant. The first end portion 21 (second end portion 22) can be formed at the end portion of the main body portion while maintaining an elliptical shape. Therefore, in each of the first cylindrical member 11 and the second cylindrical member 12, the main body portion having an elliptical cross section and the end portion having a circular cross section can be smoothly connected. Thereby, the shape of protector 100A can be simplified and manufacturing cost can be reduced. A circle has a shape having rotational symmetry n times (n is a natural number of 1 or more).

  The protector 100B is formed by sequentially arranging the first cylindrical member 11, the cylindrical member 13, the cylindrical member 14, and the second cylindrical member 12 in the axial direction, and opposing ends are fixed to each other. This is a single cylindrical body (see FIG. 9). On the other end side of the tubular member 13 (on the first end portion 21 side of the first tubular member 11), a second end portion 22 a having the same configuration as the second end portion 22 is formed. A first end 21 a having the same configuration as the first end 21 is formed on the side. Further, a second end 22a having the same configuration as the second end 22 is formed on the other end side (the first end 21a side of the tubular member 13) of the cylindrical member 14, and one end thereof is formed. A first end 21 b having the same configuration as the first end 21 is formed on the side.

  And the 1st end part 21 of the 1st cylindrical member 11, the 2nd end part 22a of the cylindrical member 13, the 1st end part 21a of the cylindrical member 13, the 2nd end part 22b of the cylindrical member 14, and a cylinder The relative positions of the first end 21b of the cylindrical member 14 and the second end of the second cylindrical member 12 are adjusted and fixed. Thereby, in protector 100B, a bending angle and a bending direction can be adjusted in each of the connection part of three edge parts. If a plurality of cylindrical members each having contact portions provided obliquely with respect to the axial direction are connected to both ends, such as the cylindrical members 13 and 14 of the protector 100B, the wires of a complicated routing path The harness can be protected more easily.

  In the cylindrical member 13, the outer diameters of the second end 22a and the first end 21a are set larger than the outer diameter of the main body portion (see FIG. 13). Similarly to the cylindrical member 13, the cylindrical member 14 is set such that the outer diameters of the first end portion 21 b and the second end portion 22 b are larger than those of the main body portion. Thereby, the diameter of the main-body part of each cylindrical member with which the protector 100B is provided is set to the same size. As described above, when connecting a plurality of cylindrical members each having the contact portions provided obliquely with respect to the axial direction at both ends, the diameters of the main body portions of the respective cylindrical members to be connected are mutually equal. If the same size is set, an increase in the types of cylindrical members can be suppressed even if the number of connected cylindrical members increases. In this case, as shown in FIG. 13, the end surfaces of the two cylindrical members are abutted with each other and the end surfaces of the two cylindrical members are fixed to each other. Is done. Therefore, for example, a locking piece formed at one end and having a locking claw at the tip is inserted into a locking hole formed at the other end along the rotationally symmetric axis L3 direction. A structure may be employed in which the first end and the second end are fixed to each other by being locked to the frame portion of the locking hole.

<Embodiment 2>
The protector 100C according to the second embodiment is configured to include a first cylindrical member 51 and a second cylindrical member 52 that are respectively formed of resin or the like (see FIGS. 10 to 12). The first end 61 on the one end side of the first tubular member 51 has an oblique direction (arrow K1 direction) with respect to the axis L1 direction (longitudinal direction, the wiring direction of the wire harness) of the first tubular member 51. A first flange portion 71 having an outer peripheral end surface (“first contact portion”) 81 extending in a band shape is provided. A second flange portion 72 is provided at the second end portion 62 on the other end side of the second cylindrical member 52.

  The second flange portion 72 has a bottom surface 92 extending in a band shape along an oblique direction (arrow K1 direction) with respect to the direction of the axis L2 (longitudinal direction, wiring direction of the wire harness) of the second cylindrical member 52. The hollow part 93 provided with is formed. The first cylindrical member 51 has the same structure as the first cylindrical member 11 of the protector 100A except for the first end 61. Further, the second tubular member 52 has the same structure as the second tubular member 12 of the protector 100A except for the second end portion 62.

  In the protector 100C, the first cylindrical member 51 and the second cylindrical member 52 form one cylindrical body in which the respective internal spaces communicate with each other with the outer peripheral end surface 81 and the bottom surface 92 in contact with each other. Thus, the first end 61 and the second end 62 are fixed to each other. A wire harness is inserted into the protector 100C and the path is restricted. Note that the protector 100C and the wire harness inserted through the protector 100C are wire harnesses with protectors.

  If the rotation angle of the second end portion 22 along the circumferential direction is changed with respect to the outer peripheral end surface 81, the bending angle and the bending direction of the second cylindrical member 52 with respect to the first cylindrical member 51 can be changed. . Therefore, by adjusting the rotation angle of the bottom surface 92 according to the bent path of the wired harness to be routed and fixing the first end portion 61 and the second end portion 62, the increase in the type of protector is suppressed. The wire harness that is bent and arranged in various angles and directions can be regulated.

  More specifically, the first end 61 has a positive symmetry having rotational symmetry with respect to the rotational symmetry axis L3 inclined with respect to the direction of the axis L1 (L2) of the first tubular member 51 (second tubular member 52). A first flange portion 71 having an octagonal outer peripheral end surface 81 is formed over the entire circumferential direction of the first end portion 61. The cross-sectional shape perpendicular to the rotational symmetry axis L3 of the outer peripheral end surface 81 is a regular octagon. The cross-sectional shape is not limited to a regular octagon but may be another regular polygon.

  A second flange portion 72 is formed integrally with the second end portion 62 over the entire circumferential direction. The second flange portion 72 includes a flange-like rear piece 113 and an annular front piece 114 provided at the second end 62. The front piece 114 is formed in an annular shape overlapping with the peripheral edge of the rear piece 113 in a strip shape when viewed from the direction of the rotational symmetry axis L3, and the outer edge of the rear piece 113 on the outer peripheral side of the rear piece 113 (See FIGS. 11 and 12). A recess 93 is formed between the front piece 114 and the rear piece 113 so as to cover the first flange portion 71 and be fitted to the first flange portion 71. The bottom surface 92 of the hollow portion 93 has a rotational symmetry of two or more times with respect to the rotational symmetry axis L3 common to the outer peripheral end surface 81 of the first flange portion 71. The bottom surface 92 has a shape that can be opposed to the outer peripheral end surface 81 over the entire circumference, such as a shape in which the unevenness of the outer peripheral end surface 81 is turned over so as to be able to overlap the outer peripheral side surface 31. That is, the rotational symmetry axes L3 of the outer peripheral end surface 81 and the bottom surface 92 coincide with each other. The direction of the arrow K1 oblique to the direction of the axis L1 (L2) of the first cylindrical member 51 (second cylindrical member 52) is a direction orthogonal to the direction of the rotational symmetry axis L3.

  The first end portion 61 and the second end portion 62 are formed so as to be fixable to each other in a plurality of different relative positional relationships. In each of the plurality of relative positional relationships, the rotation angles of the second flange part 72 with respect to the first flange part 71 about the rotation axis R3 are different from each other. That is, the rotation angles of the bottom surface 92 with respect to the outer peripheral end surface 81 are different from each other. The rotation axis R3 coincides with the rotational symmetry axis L3.

  Each of the plurality of relative positional relationships is a positional relationship in which the outer peripheral end surface 81 and the bottom surface 92 can overlap each other. The first flange portion 71 is fitted into the recess portion 93 so that the outer peripheral end surface 81 and the bottom surface 92 face each other over the entire circumference in one of the plurality of relative positional relationships. Thus, the first end 61 and the second end 62 are fixed to each other. And by the fitting of the first flange portion 71 and the recess portion 93, the circumferential direction of the bottom surface 92 (second flange portion 72) with respect to the outer peripheral end surface 81 (first flange portion 71) and the rotation axis R3 (rotation symmetry axis L3). ) Movement in each direction with respect to the direction is restricted. In other words, when the first flange portion 71 is fitted in the recess portion 93, the relative positional relationship between the outer peripheral end surface 81 of the first flange portion 71 and the bottom surface 92 of the recess portion 93 changes. In the circumferential direction and the rotation axis R3 (rotation symmetry axis L3) direction. Note that even if the outer peripheral end surface 81 and the bottom surface 92 cannot overlap each other over the entire circumference, and even if at least one of the outer peripheral end surface 81 and the bottom surface 92 is not rotationally symmetric, the recess 93 is bent. Since the first end portion 61 and the second end portion 62 can be fixed by, for example, forcing the first flange portion 71 into the recessed portion 93 of the second flange portion 72 and fitting it, the usefulness of the present invention can be improved. There is no loss. In addition, it is preferable that both side surface portions of the first flange portion 71 have rotational symmetry with respect to the rotational symmetry axis L <b> 3 similarly to the outer peripheral end surface 81. Further, even if the rotation axis R3 and the rotational symmetry axis L3 do not coincide with each other, the usefulness of the present invention is not impaired.

  The 1st cylindrical member 51 is a combination member of the 1st cover member 51a and the 1st accommodating member 51b similarly to the 1st cylindrical member 11 of protector 100A, and the 2nd cylindrical member 52 is the 2nd cylinder. Like the shaped member 12, it is a combination member of the second lid member 52a and the second housing member 52b (see FIGS. 10 and 11). Each of the lid member and the housing member includes a locking piece (not shown) and a locking frame that can lock the locking piece, and the locking piece is engaged with the locking frame in a state of being overlapped with each other. They are fixed to each other by stopping.

  In the case of protecting the protector 100C by inserting the wire harness into the protector 100C, for example, the first cover member 51b is covered with the first lid member 51a in a state where the wire harness is inserted through the first storage member 51b and fixed to each other. One cylindrical member 51 is formed. Then, the second lid member 52a and the second housing member 52b are separately provided so that the relative positional relationship between the outer peripheral end surface 81 of the first flange portion 71 and the bottom surface 92 of the recess portion 93 is a desired positional relationship. The second cylindrical member 52 is formed by attaching to the first cylindrical member 51 and fixing each other. The wire harness is fixed to the protector 100C by tape winding or the like so as not to move while being inserted into the protector 100C. Similarly to the protector 100A, each of the first cylindrical member 51 and the second cylindrical member 52 may be a combination member formed by three or more members. Further, at least one of the first tubular member 51 and the second tubular member 52 may be integrally formed.

  A protector 100D according to a modification of the protector 100C is formed so that the diameters of the main body portions of the first cylindrical member 51 and the second cylindrical member 53 that are fixed to each other are equal (see FIG. 14). The protector 100 </ b> D has a first flange portion formed at the first end portion 61 of the first tubular member 51 in a recess portion of the second flange portion 72 a formed at the second end portion 62 a of the second tubular member 53. The first tubular member 51 and the second tubular member 53 are fixed to each other by fitting the 71. The 2nd flange part 72a is formed so that the 1st flange part 71 can be fitted similarly to the 2nd flange part 72 of the protector 100C. Instead of the protector 100C, the configuration of the protector 100D may be employed.

  According to the protector concerning this Embodiment 1 or 2 as mentioned above, the 1st contact part (the outer peripheral side surface 31, the outer peripheral end surface 81) is extended in the diagonal direction with respect to the axial direction of the 1st cylindrical member. In addition, the second contact portion (the inner peripheral side surface 32, the bottom surface 92) extends in an oblique direction with respect to the axial direction of the second cylindrical member. Then, the first end portion and the second cylindrical member form one cylindrical body with the first contact portion and the second contact portion in contact with each other. The second end is fixed to each other. Thereby, if the rotation angle of the second contact portion along the circumferential direction of the second end portion is changed with respect to the first contact portion, the bending angle of the second cylindrical member with respect to the first cylindrical member is changed. can do. Therefore, by adjusting the rotation angle of the second abutting portion according to the bent path of the wired wiring harness and fixing the first end portion and the second end portion, an increase in the type of protector is suppressed. On the other hand, it is possible to regulate the route of the wire harness that is bent and arranged at various angles.

  Further, according to the protector according to the first or second embodiment as described above, the first contact portion and the second contact portion have two or more rotational symmetries, respectively, and are arranged around the entire circumference. Thus, it is formed in a shape that can be opposed. Then, the respective rotationally symmetric axes are opposed to each other over the entire circumference in a state where the respective axes of rotation symmetry are inclined with respect to the respective axial directions of the first cylindrical member and the second cylindrical member. Therefore, the first contact portion and the second contact portion can be easily brought into contact with each other.

  Moreover, according to the protector which concerns on this Embodiment 1 or 2 as mentioned above, a 1st end part and the said 2nd end part are the rotation angles of the 2nd contact part along the circumferential direction of a 2nd end part. Are formed so as to be fixable to each other in a plurality of relative positional relationships different from each other with respect to the first contact portion. Accordingly, the first end and the second end are fixed in a state where the relative positional relationship of the second abutting portion with respect to the first abutting portion is appropriately changed to one of the plurality of relative positional relationships. Thus, the bending angle of the second cylindrical member with respect to the first cylindrical member, that is, the bending angle of the protector can be easily changed.

  Moreover, according to the protector which concerns on this Embodiment 1 or 2 as mentioned above, the fluctuation | variation of the rotation angle of the 2nd contact part with respect to a 1st contact part, and the 2nd contact along the axial direction of a 2nd edge part. The first end and the second end are fitted and fixed to each other so as to restrict the movement of the contact portion relative to the first contact portion. Therefore, the fluctuation | variation of the bending angle of a protector can be controlled more strongly.

  Further, according to the protector according to the first embodiment as described above, one of the first end portion and the second end portion is along a direction different from the rotation axis related to the rotation angle of the second contact portion. A plurality of protrusions projecting toward the other are formed, and a plurality of recesses into which the plurality of protrusions are inserted in the projecting direction can be formed. The first end and the second end are fixed to each other by fitting each of the plurality of protrusions into the corresponding recess among the plurality of recesses. Therefore, by changing the relative positional relationship between the plurality of protrusions and the plurality of recesses in various ways, the bending angle of the protector can be changed variously, and the fluctuation of each bending angle can be changed. It can be strongly regulated.

  Moreover, according to the protector which concerns on this Embodiment 1 as mentioned above, several protrusion part has a rotational symmetry of 2 times or more regarding the rotating shaft of a 2nd contact part. Accordingly, if the plurality of recesses have the same rotational symmetry as the plurality of protrusions with respect to the rotation axis, the rotation angle of the second contact portion with respect to the first contact portion can be adjusted to be different at different rotation angles. The plurality of protrusions can be fitted into the plurality of recesses. The increase in the number of the plurality of protrusions and the plurality of recesses can be suppressed, the structure of the first end and the second end can be simplified, and the manufacturing cost of the protector can be reduced.

  Further, according to the protector according to the first embodiment as described above, the outer peripheral side surface of the first end portion and the inner peripheral side surface of the second end portion have two or more rotational symmetries, respectively, and are all mutually It is formed in a shape that can be opposed over the circumference. Each of the plurality of protrusions is provided in a rotationally symmetrical manner with respect to a rotational symmetry axis at a certain rotational angle. The plurality of relative positional relationships are the positional relationships when the second abutting portion is rotated with respect to the first abutting portion about the rotational symmetry axis for each of the predetermined rotation angles. The inner peripheral side surface is formed in a shape that can be opposed to each other over the entire circumference in any of a plurality of relative positional relationships. Therefore, it is possible to easily fit the plurality of protrusions to the plurality of concave portions while bringing the outer peripheral side surface and the inner peripheral side surface into contact with each other regardless of the bending angles of the protectors according to the plurality of relative positional relationships. it can.

  Moreover, according to the protector which concerns on this Embodiment 1 as mentioned above, while a 1st contact part is an outer peripheral side surface of a 1st end part, a 2nd contact part is an inner peripheral side surface of a 2nd end part. Yes, a plurality of protrusions are formed on one side surface of the outer peripheral side surface and the inner peripheral side surface, and a plurality of recesses are formed on the other side surface. Therefore, the first contact portion and the second contact portion are firmly in contact with each other by fitting the plurality of protrusions and the plurality of recesses formed directly on the first contact portion and the second contact portion. Is done. Further, the relative movement in the radial direction between the first contact portion and the second contact portion can also be restricted by the contact itself between the first contact portion and the second contact portion. Thereby, a 1st end part and a 2nd end part can be fixed more firmly, and the fluctuation | variation of the bending angle of a protector can be controlled more strongly.

  Moreover, according to the protector which concerns on this Embodiment 1 as mentioned above, each of several recessed part is a through-hole which penetrates the wall surface in which the said several recessed part is formed, and each of several protrusion part is multiple. Each of the recesses penetrates and fits into a corresponding recess. Therefore, since the contact portion between the projection and the recess can be increased, the first end and the second end can be more firmly fixed.

  Moreover, according to the protector which concerns on this Embodiment 1 as mentioned above, the cross-sectional shape perpendicular | vertical to the axial direction of main-body parts other than a 1st edge part among 1st cylindrical members, and 1st among 2nd cylindrical members. Since the cross-sectional shapes perpendicular to the axial direction of the main body portion other than the two end portions are each elliptical, the cross-sectional shape at a predetermined angle oblique to the axial direction can be made circular. Accordingly, the main body portion having an elliptical cross section and the end portion having a circular cross section can be smoothly connected.

  Moreover, according to the protector which concerns on this Embodiment 2 as mentioned above, the 1st flange part formed over the whole circumferential direction of a 1st edge part is a bowl over the whole circumferential direction of a 2nd edge part. The first end portion and the second end portion are fixed to each other by fitting into the recess of the second flange portion formed in the above manner. In this state, the respective rotational symmetry axes of the outer peripheral end surface of the first flange portion and the bottom surface of the hollow portion and the rotational shaft of the bottom surface are the axial directions of the first cylindrical member and the second cylindrical member, respectively. The outer peripheral end face and the bottom face each other over the entire circumference. Therefore, regardless of the rotation angle of the bottom surface with respect to the outer peripheral end surface, the outer peripheral end surface and the bottom surface can be easily brought into contact with each other. Thereby, the 1st end part and the 2nd end part can be firmly fixed, suppressing the change of the relative positional relationship of an outer peripheral end surface and a bottom face, ie, the change of the bending angle of a protector.

  Moreover, according to the protector which concerns on this Embodiment 2 as mentioned above, the outer peripheral end surface (1st contact part) of a 1st flange part is formed in the regular polygon shape which has rotational symmetry about a rotational symmetry axis. . Further, the bottom surface (second contact portion) of the hollow portion of the second flange portion is formed in a shape that can be opposed to the outer peripheral end surface over the entire circumference. Therefore, since the movement of the bottom surface of the hollow portion of the second flange portion with respect to the outer peripheral end surface of the first flange portion can be more reliably restricted, fluctuations in the bending angle of the protector can be further restricted.

  Moreover, according to the protector which concerns on this Embodiment 1 or 2 as mentioned above, the angle of the extension direction of the 1st contact part with respect to the axial direction of a 1st cylindrical member, and the axial direction of a 2nd cylindrical member The angle in the extending direction of the second contact portion is the same angle. Therefore, since the first end portion and the second end portion can be fixed while the axial direction of the first cylindrical member and the axial direction of the second cylindrical member are made the same direction, the first cylindrical member and the second cylindrical portion can be fixed. The shape of the cylindrical body formed by the cylindrical member, that is, the shape of the protector can be not only a bent shape but also a linear shape.

Therefore, the angle of the second cylindrical member in the axial direction relative to the axial direction of the first cylindrical member, that is, the bending angle of the protector can be set to an angle in the range of 0 to 90 degrees. Therefore, the path of the wire harness that is bent and arranged at various angles can be regulated.

  Further, according to the protector according to the first or second embodiment as described above, at least one of the first cylindrical member and the second cylindrical member includes a plurality of the cylindrical members in the circumferential direction. A plurality of members formed in each of the divided shapes are combined members that are combined and fixed so as to form a cylindrical body. Therefore, since the wire harness can be routed with respect to at least one of the first tubular member and the second tubular member in a state where the tubular member is not closed, the routing operation is facilitated. In addition, for example, the first end and the second end can be fixed by a fitting structure including a protrusion and a recess provided in the radial direction of the cylindrical member. Can be fixed more firmly.

  As mentioned above, although this invention was demonstrated in detail, above-described description is an illustration in all the aspects, Comprising: This invention is not limited to it. It is understood that countless variations that are not illustrated can be envisaged without departing from the scope of the present invention.
