[0004] In the methods disclosed in Patent Documents 1 to 4, when a bending load is applied to the fishing core or core material, the end of the pipe-shaped tube that comes into contact with the fishing core or core material may be damaged. The grip or tube, etc., has a axial hole with a space between the inner surface of the tube and the outer surface of the core material. The hole facing the core material is cylindrical, and the opposite end is fixed with a cylindrical bushing. When attaching the tube of a pipe-shaped grip, pipe, or pipe-shaped reel seat to the core material, a space is formed between the inner surface of the tube and the outer surface of the core material, and cylindrical bushings are used to secure both ends. Because both ends of each tube are fixed with cylindrical bushings, when the core material is bent and a load is applied, a gap forms between the outer surface of the bushing and the connecting surface of the tube, causing damage to the tube.

[0021] Embodiment 1 A component 3 according to an embodiment of the present invention will be described below with reference to the drawings. For ease of understanding, mutually orthogonal XYZ coordinates will be set and referenced as appropriate.

[0022] The core material 1 includes a fishing core and is used in a fishing rod together with a fishing line, a float, a fishing hook, etc. to catch fish. As shown in FIGS. 1A to 1C, the core material 1 is a rod-shaped member extending in an axial direction A1. However, this is not limited thereto. The core material 1 may be used in any fishing implement that requires the core material 1 to bend. The core material 1 may be, for example, the core material of a golf club. A cylindrical first tubular body 100 is attached to the core material 1 by a part 3 that attaches a grip-pipe-pipe type reel seat 2 to the core material 1. The first tubular body 100 is a tubular body that constitutes the grip-pipe-pipe type reel seat 2. However, this is not limited thereto. The first tubular body 100 may be any tubular body having a grip or pipe shape that can be attached to the core material 1. The inner diameter of the first tubular body 100 is larger than the diameter of the core material 1. A frame pipe 2a may be provided inside the first tubular body 100. The frame pipe 2a of the first pipe 100 is provided to increase the rigidity of the first pipe 100 by adhering closely to the cylindrical inner peripheral surface of the first pipe 100. The first pipe 100 has an axial hole at one end of the cylindrical shape facing the core material 1 in the axial direction A1, and the diameter of the inner peripheral surface of the cylindrical portion of the first pipe 100 is larger than the diameter of the axial hole. However, this is not limited to this. The first pipe 100 may have another shape.

[0023] The parts 3 are used in pairs. The two parts 3 are attached to the core material 1, and then the first tubular body 100 is attached. The two parts 3 are individually attached to both ends of the first tubular body 100 in the axial direction A1. The two parts 3 have the same structure and are attached in opposite directions in the axial direction A1. However, this is not limited to this. The two parts 3 may have different structures. For example, if one part 3 has a structure that does not allow the core material 1 to pass through it, the other part 3 has a structure that allows the core material 1 to pass through it. The part 3 will be described below based on the part 3 on the +Y side of the first tubular body 100. As shown in FIGS. 2 and 3 , the part 3 includes a connecting portion 10, a main body portion 20, and a first fitting portion 30. The part 3 may also be used in combination with a cylindrical, bush-like part.

[0024] The connecting portion 10 is a cylindrical member. The connecting portion 10 is attached to the core material 1. The connecting portion 10 is tapered toward the core of the core material 1. The surface of the connecting portion 10 on the -Y axis side is inclined toward the +Y axis direction as it approaches the core of the core material 1. The surface of the connecting portion 10 on the +Y axis side is inclined toward the -Y axis direction as it approaches the core of the core material 1. However, this is not limited to this. For example, as shown in FIG. 4, the connecting portion 10 may be a protrusion having a triangular or semicircular YZ cross section. The outer diameter of the connecting portion 10 is constant and is smaller than the inner diameter of the first tubular body 100 as shown in FIG. 5. The length A1 of the outer peripheral surface of the connecting portion 10 in the axial direction is designated D1 as shown in FIG. 2. The length D1 of the outer peripheral surface of the connecting portion 10 can be selected depending on the ease of bending of the core material 1 and the intended use. An axial hole 11 is formed in the connecting portion 10.

[0025] As shown in Figures 2 and 3, the axial hole 11 is a through hole formed in the axial direction A1. However, this is not limited to this. The axial hole 11 may also be a blind hole formed in the axial direction A1 from the -Y side surface of the connection part 10. The diameter of the axial hole 11 is large enough to allow the core material 1 to be inserted therein. Specifically, the diameter of the axial hole 11 is approximately the same as or slightly larger than the diameter of the core material 1.

[0026] The inner peripheral surface of the axial hole 11 or its apex area faces the core material 1. An adhesive member (not shown), which is an elastic adhesive, is attached to the inner peripheral surface of the axial hole 11 to bond it to the core material 1. However, this is not limited to this. The adhesive member attached to the inner peripheral surface of the axial hole 11 may be a soft adhesive member that is flexible enough to not peel off even when the adhesive surface is bent. The length of the inner peripheral surface of the axial hole 11 in the axial direction A1 is d1. The length d1 of the inner peripheral surface of the axial hole 11 is shorter than the length D1 of the outer peripheral surface of the connection portion 10. Therefore, when the core material 1 is bent, the area where the inner peripheral surface of the axial hole 11 presses the core material 1 is reduced, and the load on the connection portion 10 is reduced. Furthermore, since the volume of the connection portion 10 is reduced, the component 3 can be made lighter.

[0027] The main body 20 is a member having a cylindrical shape. The main body 20 is attached to the outer peripheral surface of the connection part 10. The main body 20 has a pair of side surfaces in the axial direction A1, one main body side surface 20a on the -Y side and the other main body side surface 20b on the +Y side. The outer diameter of the main body 20 is equal to or smaller than the outer diameter of the first tubular body 100. A main body hole 21 is formed in the main body 20.

[0028] The main body hole 21 is a through hole formed in the axial direction A1. However, this is not limited to this. The main body hole 21 may also be a blind hole formed in one of the main body side surfaces 20a in the axial direction A1. The diameter of the main body hole 21 is large enough to allow the connection part 10 to be inserted therein for connection. Specifically, the diameter of the main body hole 21 is approximately the same as or slightly larger than the outer diameter of the connection part 10. The inner peripheral surface of the main body hole 21 faces at least a portion of the outer peripheral surface of the connection part 10.

[0029] The first fitting portion 30 is a cylindrical member. The outer diameter of the first fitting portion 30 is constant and is larger than the outer diameter of the connection portion 10 and is approximately the same as or slightly smaller than the inner diameter of the first tubular body 100. As shown in FIG. 2 , the first fitting portion 30 is connected to the outer circumferential surface of the main body portion 20 and attached to the connection portion 10 via the main body portion 20. However, this is not limited thereto. The first fitting portion 30 does not have to be connected to the main body portion 20 and attached to the connection portion 10 via the main body portion 20. Specifically, when the outer diameter of the main body portion 20 is smaller than the outer diameter of the first tubular body 100, the first fitting portion 30 is connected to the outer circumferential surface of the main body portion 20. When the outer diameter of the main body portion 20 is approximately the same as the outer diameter of the first tubular body 100, as shown in FIG. 3 , the first fitting portion 30 is connected to the other main body side surface 20b of the main body portion 20 and attached to the connection portion 10. The first fitting portion 30 has a first fitting hole 31 formed therein.

[0030] As shown in FIGS. 2 and 3 , the first fitting hole 31 is a through hole formed in the axial direction A1. However, this is not limited thereto. The first fitting hole 31 may be a blind hole formed in the axial direction A1 from the -Y side surface of the first fitting portion 30. The diameter of the first fitting hole 31 is equal to or greater than the outer diameter of the connection portion 10. Specifically, when the outer diameter of the main body portion 20 is smaller than the outer diameter of the first tubular body 100, the diameter of the first fitting hole 31 is approximately the same as the outer diameter of the main body portion 20, and the inner circumferential surface of the first fitting hole 31 faces the outer circumferential surface of the main body portion 20. When the outer diameter of the main body portion 20 is approximately the same as the outer diameter of the first tubular body 100, the diameter of the first fitting hole 31 is approximately the same as the outer diameter of the connection portion 10, and the inner circumferential surface of the first fitting hole 31 faces the outer circumferential surface of the connection portion 10.

[0031] The main body 20 and the first fitting portion 30 are combined to form a single ring 40. When the outer diameter of the main body 20 is smaller than the inner diameter of the first tubular body 100, the ring 40 is connected so that the main body 20 is positioned inside the first fitting hole 31 of the first fitting portion 30. When the outer diameter of the main body 20 is approximately the same as the inner diameter of the first tubular body 100, the ring 40 is connected so that the first fitting portion 30 is positioned on the +Y side of the main body 20, as shown in FIG. As shown in FIG. 2, when the outer diameter of the main body 20 is smaller than the inner diameter of the first tubular body 100, the annular body 40 comprises only the main body hole 21. When the outer diameter of the main body portion 20 is approximately the same as the inner diameter of the first tubular body 100, the main body hole 21 is a through hole, and a continuous hole consisting of the main body hole 21 and the first fitting hole 31 is formed, as shown in Figure 3. The length of the annular body 40 in the axial direction A1 is approximately the same as the length of the connecting portion 10 in the axial direction A1.

[0032] Next, the manner in which the component 3 is used will be described.

[0033] First, the components 3 are assembled as shown in Figures 2 and 3. Specifically, the main body 20 and the first fitting portion 30, each with an adhesive attached, are connected to form the ring 40, and the connecting portion 10, with an adhesive attached to its outer surface (not shown), is inserted into the hole in the ring 40. The connecting portion 10 and the ring 40 are then fixed together with the adhesive. However, this is not limited to this. When the main body 20 and the first fitting portion 30 are a single unit, or when the connecting portion 10 and the ring 40 are a single unit, the integrated portions do not need to be assembled. Another component 3 is assembled using the same procedure. At least one of the two components 3 has a structure that allows the core material 1 to penetrate.

[0034] Next, as shown in FIG. 5, the core material 1 is inserted into one of the parts 3. Specifically, the core material 1 is inserted into the axial hole 11 of the connecting portion 10 of the one of the parts 3. The one of the parts 3 is fixed with the adhesive material so that the core material 1 faces the first opposing surface 11b of the axial hole 11 to which the adhesive material is attached. Then, the first tubular body 100 is inserted so that the core material 1 passes through the opening of the first tubular body 100. Furthermore, an adhesive material is attached to the outer peripheral surface of the ring body 40 of the one of the parts 3, and the first tubular body 100 is fitted into the interior through the opening on the +Y side.

[0035] Finally, the core material 1 is inserted into the other part 3, which is turned in the opposite direction in the axial direction A1. Specifically, the core material 1 is inserted into the axial hole 11 of the connecting portion 10 of the other part 3. The other part 3 is fixed with the adhesive, with the core material 1 facing the first opposing surface 11b of the axial hole 11 to which the adhesive material is attached. Then, the adhesive material is attached to the outer peripheral surface of the ring body 40 of the other part 3, and the other part 3 is fitted into the first tube 100 through the opening on the -Y side. The outer peripheral surface of the ring body 40 of the other part 3 faces the inner peripheral surface of the first tube 100 and is fixed with the adhesive. In this way, the first tube 100 is attached to the core material 1 by the two parts 3.

[0036] Although one of the components 3 is attached to the first tubular body 100 after the other component 3 is attached to the first tubular body 100, this is not limitative. The other component 3 may be attached to the first tubular body 100 after the one component 3 is attached to the first tubular body 100.

[0037] When the axial hole 11, main body hole 21, or first fitting hole 31 of one part 3 or the other part 3 is a blind hole, the axial hole 11, main body hole 21, and first fitting hole 31 of the other part are through holes.

[0038] As described above, in the component 3 according to the first embodiment, the ring 40 is fitted inside the first tubular body 100, and the core 1 is inserted into the axial hole 11 of the connecting portion 10 and supported by the first opposing surface 11b of the axial hole 11. As a result, as shown in FIG. 5(b), even if misalignment occurs between the core 1 and the two connecting portions 10 when the core 1 is bent, cracking is suppressed, the core 1 is fixed, and gaps are less likely to form between the core 1 and the connecting portions 10. Specifically, in the tubular body of a conventional cylindrical grip / pipe / pipe-type reel seat, when the core 1 is bent, load is applied to the bushings fixed to both ends of the tubular body, creating gaps between the outer circumferential surfaces of the bushings and the connecting surfaces of the tubular body, which can damage the tubular body. However, in the core material 1 and first tube body 100 using the part 3 of this embodiment 1, when the core material 1 bends and shifts inward beyond the axial holes 11 of the two connecting parts 10, the space created by the inclination of both sides of the inner surface of the axial hole 11 in the Y-axis direction allows the core material 1 to shift, so that the part 3 is less likely to be subjected to load, the part 3 and the first tube body 100 are less likely to be damaged, the core material 1 is fixed, and gaps are less likely to occur between the core material 1 and the connecting parts 10.

[0039] Embodiment 2 In the first embodiment, the end grain surface 100a on the -Y side of the first pipe 100 and the end grain surface 100b on the +Y side of the first pipe 100 were not covered. Furthermore, as shown in FIGS. 6 to 8, the end grain surfaces 100a, 100b of the first pipe 100 may be covered by the main body 20. A component 3 according to a second embodiment of the present invention will be described below with reference to the drawings. Differences from the first embodiment will be mainly described. Other than the differences described, the second embodiment is the same as or equivalent to the first embodiment.

[0040] The main body 20 is attached to the first fitting 30. The outer diameter of the main body 20 is approximately the same as or slightly larger than the outer diameter of the first tubular body 100. The main body 20 has a pair of side surfaces in the axial direction A1: one main body side surface 20a and the other main body side surface 20b. The one main body side surface 20a of the main body 20 faces and covers the end grain surface 100b on the +Y side of the first tubular body 100. The one main body side surface 20a of the main body 20 prevents cracking of the end grain surface 100b on the +Y side of the first tubular body 100. The other main body side surface 20b of the main body 20 forms the end surface of the cylindrical grip pipe consisting of the first tubular body 100. A main body hole 21 is formed in the main body 20.

[0041] The main body hole 21 is a through hole formed in the axial direction A1. However, this is not limited thereto. The main body hole 21 may be a blind hole formed in one of the main body side surfaces 20a in the axial direction A1, as shown in FIG. 8(a). The diameter of the main body hole 21 is large enough to allow the first fitting portion 30 to be inserted and connected. Specifically, the diameter of the main body hole 21 is approximately the same as or slightly larger than the outer diameter of the first fitting portion 30. The inner circumferential surface of the main body hole 21 faces a part of the outer circumferential surface of the first fitting portion 30. However, this is not limited thereto. As shown in FIG. 9(a), the main body hole 21 may have two portions with different diameters, and the diameter of one portion of the main body hole 21 may be approximately the same as or slightly larger than the outer diameter of the connection portion 10, and the diameter of the other portion of the main body hole 21 may be approximately the same as or slightly larger than the outer diameter of the first fitting portion 30. The connecting portion 10 is connected to one portion of the main body hole 21, and the first fitting portion 30 is connected to the other portion, and the first fitting portion 30 does not have to be connected to the connecting portion 10. The inner peripheral surface of one portion of the main body hole 21 faces the outer peripheral surface of the connecting portion 10, and the inner peripheral surface of the other portion faces the outer peripheral surface of the first fitting portion 30.

[0042] As shown in Figures 6 to 8, the connection part 10 and the main body part 20 are separate bodies. However, this is not limited to this. The main body part 20 and the first fitting part 30 may be a single body (not shown), or may be integral. The connection part 10 and the main body part 20 are fixed by an adhesive member made of epoxy adhesive applied to a part of the outer circumferential surface of the connection part 10. However, this is not limited to this. The connection part 10 and the main body part 20 only need to be fixed so as not to be misaligned. The main body part 20 and the first fitting part 30 may be fixed by, for example, a fixing metal fitting. The adhesive member may be, for example, a liquid adhesive.

[0043] The first fitting portion 30 is a cylindrical member. The first fitting portion 30 is attached to the connection portion 10. The outer diameter of the first fitting portion 30 is constant and is larger than the outer diameter of the connection portion 10, and is approximately the same as or slightly smaller than the inner diameter of the first tubular body 100. A first fitting hole 31 is formed in the first fitting portion 30.

[0044] The first fitting hole 31 is a through hole formed in the axial direction A1. However, this is not limited thereto. The first fitting hole 31 may be a blind hole formed in the axial direction A1 from the -Y side surface of the first fitting portion 30. The diameter of the first fitting hole 31 is large enough to allow the connection portion 10 to be inserted therein for connection. Specifically, the diameter of the first fitting hole 31 is approximately the same as or slightly larger than the outer diameter of the connection portion 10. At least a portion of the inner circumferential surface of the first fitting hole 31 faces the outer circumferential surface of the connection portion 10.

[0045] The connecting portion 10 and the first fitting portion 30 are combined so that the connecting portion 10 is located at the +Y side end of the first fitting hole 31 of the first fitting portion 30. However, this is not limited to this. The connecting portion 10 and the first fitting portion 30 may be combined so that the inner circumferential surface of the first fitting hole 31 of the first fitting portion 30 faces the outer circumferential surface of the connecting portion 10. The connecting portion 10 and the first fitting portion 30 may be combined, for example, so that they are located at the center inside the first fitting hole 31 of the first fitting portion 30. The connecting portion 10 and the first fitting portion 30 may be combined so that the entire outer circumferential surface of the connecting portion 10 faces the entire inner circumferential surface of the first fitting hole 31 of the first fitting portion 30, for example, if the length in the axial direction A1 of the inner circumferential surface of the first fitting hole 31 is equal to the length D1 in the axial direction A1 of the outer circumferential surface of the connecting portion 10. The connecting portion 10 and the first fitting portion 30 are separate bodies. However, this is not limited to this. The connecting portion 10 and the first fitting portion 30 may be, for example, a single body (not shown) or an integrated body. Furthermore, the connecting portion 10 and the first fitting portion 30 may be a single body or an integrated body, and the main body 20 may also be a single body or an integrated body. The connecting portion 10 and the first fitting portion 30 are fixed by an adhesive member attached to the outer circumferential surface of the connecting portion 10.

[0046] The main body portion 20 and the first fitting portion 30 are combined so that the +Y side end of the first fitting portion 30 is located inside the main body hole 21 of the main body portion 20. The main body portion 20 and the first fitting portion 30 are combined so that a portion of the outer surface of the first fitting portion 30 faces the inner circumferential surface of the main body hole 21 of the main body portion 20. The main body portion 20 and the first fitting portion 30 are combined so that at least the -Y side end of the first fitting portion 30 protrudes from one of the main body side surfaces 20a of the main body portion 20. The main body portion 20 and the first fitting portion 30 are separate bodies. However, this is not limited to this. The main body portion 20 and the first fitting portion 30 may be a single body or an integrated body (not shown). Furthermore, the main body portion 20 and the first fitting portion 30 may be a single body or an integrated body (not shown), and the connection portion 10 may also be a single body or an integrated body (not shown). The main body portion 20 and the first fitting portion 30 are fixed together by an adhesive member applied to a part of the outer circumferential surface of the first fitting portion 30 .

[0047] The lengths in the axial direction A1 of the connecting portion 10, the main body portion 20, and the first fitting portion 30 are formed such that the length D1 of the outer peripheral surface of the connecting portion 10 is equal to the length of the main body portion 20 in the axial direction A1, and the length of the first fitting portion 30 in the axial direction A1 is longer than the length D1 of the outer peripheral surface of the connecting portion 10 and the length of the main body portion 20 in the axial direction A1. However, this is not limited to this. The lengths in the axial direction A1 of the connecting portion 10, the main body portion 20, and the first fitting portion 30 may be, for example, such that the length D1 of the outer peripheral surface of the connecting portion 10 is longer than the length of the main body portion 20 in the axial direction A1, but is equal to or shorter than the length D1 of the first fitting portion 30 in the axial direction A1. The lengths in the axial direction A1 of the connecting portion 10, the main body portion 20, and the first fitting portion 30 may be, for example, such that the length D1 of the outer peripheral surface of the connecting portion 10 is shorter than the length of the main body portion 20 in the axial direction A1.

[0048] Next, a description will be given of how the component 3 according to the second embodiment is used.

[0049] First, the component 3 is assembled. Specifically, as shown in FIGS. 6 and 7 , the first fitting portion 30, which has an adhesive member attached to its outer periphery, is inserted into the main body hole 21 of the main body 20, and the connecting portion 10, which has an adhesive member attached to its outer periphery, is inserted into the first fitting hole 31 of the first fitting portion 30. The connecting portion 10, the main body 20, and the first fitting portion 30 are then fixed together with the adhesive member. However, this is not limited to this. The connecting portion 10, the main body 20, and the first fitting portion 30 may be a single or integral body, or the main body 20 and the first fitting portion 30 may be a single or integral body, or the connecting portion 10, the first fitting portion 30, and the main body 20 may all be a single or integral body. In this case, the single or integral parts do not need to be assembled. Another component 3 is assembled using the same procedure. At least one of the two components 3 has a structure that allows the core material 1 to penetrate through it.

[0050] Next, the core material 1 is inserted into one of the components 3. Specifically, the core material 1 is inserted into the axial hole 11 of the connecting portion 10 of the one of the components 3. The core material 1 faces the first opposing surface 11b of the axial hole 11, to which the adhesive material is attached, and they are fixed together with the adhesive material. Then, the first tube 100 is inserted so that the core material 1 passes through the opening of the first tube 100. Furthermore, an adhesive material is attached to the outer peripheral surface of the first fitting portion 30 protruding from one of the body side surfaces 20a of the main body portion 20 of the one of the components 3, and the first tube 100 is fitted into the +Y side opening of the first tube 100, so that the +Y side butt end surface 100b of the first tube 100 faces one of the body side surfaces 20a of the main body portion 20 and covers it. The outer peripheral surface of the first fitting portion 30 of the one of the components 3 faces the inner peripheral surface of the first tube 100 and is fixed together with the adhesive material.

[0051] Finally, the core material 1 is inserted into the other part 3, which is oriented in the opposite direction in the axial direction A1. Specifically, the core material 1 is inserted into the axial hole 11 of the connecting portion 10 of the other part 3. The other part 3 is fixed with the adhesive, with the core material 1 facing the first opposing surface 11b of the axial hole 11 to which the adhesive material is attached. Then, the adhesive material is attached to the outer peripheral surface of the first fitting portion 30 protruding from one main body side surface 20a of the main body portion 20 of the other part 3, and the other part 3 is fitted into the first tubular body 100 through the opening on the -Y side, so that the end face 100a on the -Y side of the first tubular body 100 faces one main body side surface 20a of the main body portion 20 of the other part 3 and covers it. The outer peripheral surface of the first fitting portion 30 of the other part 3 faces the inner peripheral surface of the first tubular body 100 and is fixed with the adhesive material. As a result, the first tubular body 100 is attached to the core material 1 by the two parts 3 .

[0052] Although one of the components 3 is attached to the first tubular body 100 after the other component 3 is attached to the first tubular body 100, this is not limitative. The other component 3 may be attached to the first tubular body 100 after the one component 3 is attached to the first tubular body 100.

[0053] When the axial hole 11, the first fitting hole 31, or the main body hole 21 of one part 3 or the other part 3 is a blind hole, the axial hole 11, the first fitting hole 31, and the main body hole 21 of the other part are through holes.

[0054] As described above, in the component 3 according to the second embodiment, as shown in Fig. 6(c), the end grain surface 100b on the +Y side of the first tubular body 100 is covered by facing one of the body side surfaces 20a of one component 3, and the end grain surface 100a on the -Y side of the first tubular body 100 is covered by facing one of the body side surfaces 20a of the other component 3. This allows the end grain surface 100a on the -Y side of the first tubular body 100 and the end grain surface 100b on the +Y side of the first tubular body 100 to be protected by the component 3, making it possible to suppress cracking.

[0055] Embodiment 3 In the second embodiment described above, the first fitting portion 30 is inserted into the main body hole 21 of the main body portion 20. However, this is not limited to this. As shown in FIGS. 10(a) and 10(b), only the connection portion 10 may be inserted into the main body hole 21 of the main body portion 20, and the first fitting portion 30 may not face the main body portion 20. Below, a component 3 according to the third embodiment of the present invention will be described using the drawings. Differences from the second embodiment will be mainly described. Other than the differences described, the component 3 is the same as or equivalent to the second embodiment.

The two parts 3 are attached to both ends of the first tubular body 100 in the axial direction A1. The two parts 3 have the same structure and are attached in opposite directions in the axial direction A1. However, this is not limited to this. The two parts 3 may have different structures. For example, if one part 3 has a structure that does not allow the core material 1 to pass through it, the other part 3 has a structure that allows the core material 1 to pass through it. The parts 3 will be described below based on the part 3 on the +Y side of the first tubular body 100. As shown in FIGS. 10(a) and 10(b), the part 3 includes a connecting portion 10, a main body portion 20, a first fitting portion 30, and a first groove portion 50.

[0057] The length D1 of the outer peripheral surface of the connecting portion 10 in the axial direction A1 is longer than the sum of the length of the outer peripheral surface of the first fitting portion 30 in the axial direction A1 and the length of the outer peripheral surface of the main body portion 20 in the axial direction A1.

[0058] The first fitting portion 30 is attached to the end portion on the -Y side of the connection portion 10. The first fitting portion 30 has a first fitting hole 31 formed therein.

[0059] The inner circumferential surface of the first fitting hole 31 faces at least a part of the outer circumferential surface of the connection part 10 .

[0060] The main body portion 20 is attached to the end portion on the +Y side of the connection portion 10. The main body portion 20 is disposed at a distance from the first fitting portion 30. The main body portion 20 is a separate body from the connection portion 10. However, this is not limited to this. The main body portion 20 may be, for example, a single body (not shown) or integral with the connection portion 10. The main body portion 20 may be, for example, a single body (not shown) or integral with the connection portion 10 and the first fitting portion 30. A main body hole 21 is formed in the main body portion 20.

[0061] The main body hole 21 is a through hole formed in the axial direction A1. However, this is not limited thereto. The main body hole 21 may also be a blind hole formed in one of the main body side surfaces 20a in the axial direction A1. Furthermore, as shown in FIG. 11 , the main body hole 21 may be a blind hole formed by: an outer ring portion 20c in the main body 20, which has a cylindrical shape and has a through hole formed in the axial direction A1 that is larger in diameter than the main body hole 21; an inner ring portion 20d in the main body 20, which has a cylindrical shape and is disposed inside the through hole of the outer ring portion 20c and has a through hole formed in the axial direction A1 that is equal in diameter to the main body hole 21; and a cover portion 20e that closes the through hole of the outer ring portion 20c. The diameter of the main body hole 21 is large enough to allow the connecting portion 10 to be inserted and connected, as shown in FIG. 10 . Specifically, the diameter of the main body hole 21 is approximately the same as or slightly larger than the outer diameter of the connecting portion 10. The inner peripheral surface of the main body hole 21 faces a part of the outer peripheral surface of the connection part 10 .

[0062] The connecting part 10 and the main body part 20 are combined so that the +Y side end of the connecting part 10 is located inside the main body hole 21 of the main body part 20. The connecting part 10 and the main body part 20 are combined so that a part of the outer surface of the connecting part 10 faces the inner surface of the main body hole 21 of the main body part 20. The connecting part 10 and the main body part 20 are combined so that at least the -Y side end of the connecting part 10 protrudes from one of the main body side surfaces 20a of the main body part 20.

[0063] The first groove portion 50 is formed between the main body portion 20 and the first fitting portion 30, which are arranged apart from each other. The first groove portion 50 is formed by the exposed outer peripheral surface of the connection portion 10, the side surface on the +Y side of the first fitting portion 30, and one main body side surface 20a of the main body portion 20.

[0064] As described above, in the component 3 according to the third embodiment, the main body 20 and the first fitting portion 30 are disposed at a distance from each other, and the first groove 50 is formed between one main body side surface 20a of the main body 20 and the first fitting portion 30. As a result, when the first fitting portion 30, which has an adhesive member applied to its outer circumferential surface, is fitted into the first tubular body 100 through the opening on the +Y side, the excess adhesive member is removed into the first groove 50, and the outer circumferential surface of the first fitting portion 30 and the inner circumferential surface of the first tubular body 100 can be fixed evenly.

[0065] Embodiment 4 In the above-described second embodiment, the component 3 is attached only to the first tube 100. However, this is not limited to this. The component 3 may be attached to both the first tube 100 and another tube, the second tube 200. The second tube 200 has an axial hole at one end of its cylindrical shape that faces the core material 1 in the axial direction A1, and the diameter of the inner circumferential surface of the cylindrical portion of the second tube 200 is larger than the diameter of the axial hole. The component 3 according to the fourth embodiment of the present invention will be described below with reference to the drawings. Differences from the second embodiment will be mainly described. Other than the differences described, the second embodiment is the same or equivalent to the second embodiment.

[0066] After the part 3 is attached to the core 1, the first tubular body 100 and the second tubular body 200 are attached. The part 3 is attached to the +Y side end of the first tubular body 100 and the -Y side end of the second tubular body 200. As shown in FIGS. 12(a) to 12(c), the part 3 includes a connecting portion 10, a main body portion 20, and a first fitting portion 30.

[0067] The main body hole 21 of the main body portion 20 is a through hole formed in the axial direction A1. The diameter of the main body hole 21 is large enough to allow the first fitting portion 30 to be inserted and connected. Specifically, the diameter of the main body hole 21 is approximately the same as or slightly larger than the outer diameter of the first fitting portion 30. The inner circumferential surface of the main body hole 21 faces a part of the outer circumferential surface of the first fitting portion 30.

[0068] The main body portion 20 and the first fitting portion 30 are combined so that the center of the first fitting portion 30 in the axial direction A1 is located inside the main body hole 21 of the main body portion 20. The main body portion 20 and the first fitting portion 30 are combined so that a portion of the outer peripheral surface of the first fitting portion 30 faces the inner peripheral surface of the main body hole 21 of the main body portion 20. The main body portion 20 and the first fitting portion 30 are combined so that at least the -Y side end of the first fitting portion 30 protrudes from one main body side surface 20a of the main body portion 20. Furthermore, the main body portion 20 and the first fitting portion 30 are combined so that at least the +Y side end of the first fitting portion 30 protrudes from the other main body side surface 20b of the main body portion 20.

[0069] The -Y side end of the first fitting portion 30 protrudes from one of the body side surfaces 20a of the body portion 20. An adhesive member is attached to the outer peripheral surface of the -Y side end of the first fitting portion 30. The -Y side end of the first fitting portion 30 is fitted into the interior of the first pipe 100 through an opening on the +Y side, and covers the +Y side butt end surface 100b of the first pipe 100, facing one of the body side surfaces 20a of the body portion 20.

[0070] The +Y side end of the first fitting portion 30 protrudes from the other main body side surface 20b of the main body portion 20. An adhesive member is attached to the outer peripheral surface of the +Y side end of the first fitting portion 30. The +Y side end of the first fitting portion 30 is fitted into the interior through the -Y side opening of the second pipe 200, and covers the -Y side butt end surface 200a of the second pipe 200 by facing it to the other main body side surface 20b of the main body portion 20. The outer peripheral surface of the +Y side end of the first fitting portion 30 faces the inner peripheral surface of the second pipe 200 and is fixed thereto by an adhesive member.

[0071] As described above, in component 3 according to the fourth embodiment, at least the −Y side end of first fitting portion 30 protrudes from one body side surface 20a of body portion 20, and at least the +Y side end of first fitting portion 30 protrudes from the other body side surface 20b of body portion 20. This allows the −Y side end of first fitting portion 30 to be fitted inside first tubular body 100, and the +Y side end of first fitting portion 30 to be fitted inside second tubular body 200, thereby connecting first tubular body 100 and second tubular body 200. Then, by covering the end grain surface 100b on the +Y side of the first pipe 100 with one of the main body side surfaces 20a of the main body portion 20 and covering the end grain surface 200a on the -Y side of the second pipe 200 with the other main body side surface 20b of the main body portion 20, the end grain surface 100b on the +Y side of the first pipe 100 and the end grain surface 200a on the -Y side of the second pipe 200 can be protected by part 3 and cracks can be suppressed.

[0072] The component 3 according to the fourth embodiment is used in combination with the component 3 according to the first, second, or third embodiment, and the first fitting portion 30 of the component 3 according to the first or second embodiment can be fitted into the first tubular body 100 through the opening on the -Y side and the opening on the +Y side of the second tubular body 200. As a result, even if misalignment occurs between the core material 1 and the two connecting portions 10 when the core material 1 is bent, cracks are suppressed, the core material 1 is fixed, and gaps are less likely to occur between the core material and the connecting portions 10.

[0073] Embodiment 5 In the second embodiment described above, the first fitting portion 30 is inserted into the main body hole 21 of the main body 20, and the component 3 is attached only to the first tubular body 100. However, this is not limited to this. Only the connection portion 10 may be inserted into the main body hole 21 of the main body 20, and the first fitting portion 30 may not face the main body 20. Furthermore, the component 3 may be attached to both the first tubular body 100 and the second tubular body 200, which is another tubular body. The component 3 according to the fifth embodiment of the present invention will be described below with reference to FIG. 13. Differences from the first embodiment will be mainly described. Other than the differences described, the component 3 is the same as or equivalent to the second embodiment.

[0074] After the part 3 is attached to the core material 1, the first tube 100 and the second tube 200 are attached. The part 3 is attached to the +Y side end of the first tube 100 and the -Y side end of the second tube 200. As shown in FIG. 13 , the part 3 includes a connection part 10, a main body part 20, a first fitting part 30, a first groove part 50, a second fitting part 60, and a second groove part 70.

[0131] Embodiment 12 In the above-described first to eleventh embodiments, the first tubular body 100 is cylindrical. However, this is not limited thereto. The first tubular body 100 may be provided with a partition wall portion 110a that forms an intersecting surface 120 perpendicular to the axial direction A1. The first tubular body 100 according to the twelfth embodiment of the present invention will be described below with reference to the drawings. Differences from the first to eleventh embodiments will be mainly described. Other than the differences described, the first tubular body 100 is the same as or equivalent to the first to eleventh embodiments.

[0132] As shown in FIG. 18, the first pipe 100 includes a main body 101 and a partition wall 110a formed at an end 110 of the main body 101 on the −Y side.

[0133] The main body 101 has a cylindrical shape. The main body 101 has a constant diameter. The main body 101 has a through-hole formed in the axial direction A1.

[0134] The partition wall 110a stands from the end 110 on the -Y side of the main body 101 in a direction intersecting with the core material 1. The side surface on the -Y side of the partition wall 110a forms an intersecting surface 120 that is perpendicular to the axial direction A1. An insertion hole 111 is formed in the partition wall 110a.

[0135] The insertion hole 111 is a through hole formed in the axial direction A1. The diameter of the insertion hole 111 is large enough to insert the core material 1. Specifically, the diameter of the insertion hole 111 is approximately the same as or slightly larger than the diameter of the core material 1. The diameter of the insertion hole 111 is shorter than the diameter of the inner circumferential surface of the first tubular body 100. An adhesive member is attached to the inner circumferential surface of the insertion hole 111. The inner circumferential surface of the insertion hole 111 faces the core material 1.

[0136] The core member 1 and the first pipe body 100 are fixed together by an adhesive member applied to the inner circumferential surface of the insertion hole 111 .

[0137] Embodiment 13 In the above-described embodiment 12, the first pipe 100 is provided with a partition wall 110a. Furthermore, the first pipe 100 may be formed with an insertion portion 112 that is inserted into another pipe (not shown). The first pipe 100 according to embodiment 13 of the present invention will be described below with reference to the drawings. Differences from embodiment 12 will be mainly described. Other than the differences described, the first pipe 100 is the same as or equivalent to embodiment 12.

[0138] An insertion portion 112 is formed on the core material 1 side of the partition wall portion 110a shown in FIG.

[0139] The insertion portion 112 has a cylindrical shape. The insertion portion 112 protrudes from the -Y side surface of the partition portion 110a. The insertion portion 112 is inserted into another pipe body (not shown) or the component 3 according to the first, second, or fifth embodiment. An insertion hole 111 is formed extending from the insertion portion 112.

[0140] The partition wall 110a of the first pipe 100 is formed with an insertion portion 112. However, this is not limitative and the insertion portion 112 may be an insertion piece separate from the partition wall 110a.

[0141] Embodiment 14 In the above-described embodiment 12, the first tubular body 100 is provided with a partition wall 110a. Furthermore, the first tubular body 100 may be formed with an insertion groove 113 into which another tubular body (not shown) or the component 3 according to embodiment 1, 2, or 5 is inserted. The following describes the first tubular body 100 according to embodiment 14 of the present invention with reference to the drawings. Differences from embodiment 12 will be mainly described. Other than the differences described, the first tubular body 100 is the same as or equivalent to embodiment 12.

[0142] 20 is formed with an insertion groove 113. The insertion groove 113 forms an insertion portion 112 in the partition wall 110a that does not protrude from the intersecting surface 120.

[0143] The insertion groove 113 is a round groove when viewed from the front. The insertion groove 113 is formed on the side surface on the -Y side of the partition wall portion 110a. An end portion of another tube (not shown) or the component 3 according to the first, second, or fifth embodiment is inserted into the insertion groove 113.

[0144] Embodiment 15 In the above-described embodiment 12, an insertion hole 111 is formed in the partition wall portion 110a. Furthermore, as shown in FIG. 21, the length d2 of the inner peripheral surface of the insertion hole 111 in the axial direction A1 may be shorter than the maximum length D2 of the partition wall portion 110a in the axial direction A1. A first tubular body 100 according to embodiment 15 of the present invention will be described below with reference to the drawings. Differences from embodiment 12 will be mainly described. Other than the differences described, the first tubular body 100 according to embodiment 15 is the same as or equivalent to embodiment 12.

[0145] The partition wall portion 110a is formed with an outer partition wall portion 110b, an inner partition wall portion 110c, and an axial core side end portion 110d.

[0146] The shaft-core side end 110d is an end formed in the core direction of the core material 1. The shaft-core side end 110d is inclined in a tapered shape toward the core direction of the core material 1. The surface on the -Y axis side of the shaft-core side end 110d is inclined toward the +Y axis direction as it approaches the core direction of the core material 1. The surface on the +Y axis side of the shaft-core side end 110d is inclined toward the -Y axis direction as it approaches the core direction of the core material 1. However, this is not limited to this. The shaft-core side end 110d may be, for example, a protrusion whose YZ cross section has a semicircular shape.

[0147] The outer partition wall portion 110b is the outer portion of the partition wall portion 110a. The outer partition wall portion 110b is continuous with the outer peripheral surface of the first pipe 100.

[0148] The inner partition wall portion 110c is the inner portion of the partition wall portion 110a. The inner partition wall portion 110c is continuous with the inner circumferential surface of the first tubular body 100. The length from the upper end to the lower end of the inner partition wall portion 110c is shorter than the length from the upper end to the lower end of the outer partition wall portion 110b.

[0149] The second opposing surface 111b, which is the inner circumferential surface of the insertion hole 111, faces the core material 1. An adhesive member, such as an elastic adhesive, is attached to the second opposing surface 111b of the insertion hole 111 to adhere to the core material 1. However, this is not limited to this. The adhesive member attached to the second opposing surface 111b of the insertion hole 111 may be a soft adhesive member that is flexible enough to not peel off even when the adhesive surface is bent. The length of the second opposing surface 111b of the insertion hole 111 in the axial direction A1 is d2. The length d2 of the second opposing surface 111b is shorter than the maximum length D2 of the partition wall portion 110a in the axial direction A1. Therefore, when the core material 1 is bent, the area where the second opposing surface 111b presses the core material 1 is reduced, and the load on the connection portion 10 is reduced. Furthermore, since the volume of the partition wall portion 110a is reduced, the first pipe body 100 can be made lighter.

[0150] Embodiment 16 In the above-described embodiment 15, the first tubular body 100 has a cylindrical shape, and the diameter of the main body 101 is constant. However, this is not limited to this. The partition wall portion 110a of the first tubular body 100 may have at least one of the inner diameter and the outer diameter decreasing toward the -Y axis direction. Hereinafter, the first tubular body 100 according to embodiment 16 of the present invention will be described with reference to the drawings. Differences from embodiment 15 will be mainly described. Other than the differences described, the first tubular body 100 is the same as or equivalent to embodiment 15.

[0151] As shown in Fig. 22, the first tubular body 100 has a cylindrical shape. At least one of the inner and outer diameters of the partition wall 110a of the first tubular body 100 decreases toward the -Y axis direction. An insertion hole 111 is formed in the partition wall 110a on the -Y side of the first tubular body 100.

[0152] The axial core side end 110d of the partition 110a is tapered toward the core of the core material 1. The surface on the -Y axis side of the axial core side end 110d is inclined toward the +Y axis direction as it approaches the core of the core material 1. The surface on the +Y axis side of the axial core side end 110d is inclined toward the -Y axis direction as it approaches the core of the core material 1. However, this is not limited to this. The axial core side end 110d may be, for example, a protrusion whose YZ cross section is semicircular. The outer partition 110b, which is the outer portion of the partition 110a, is continuous with the outer peripheral surface of the first tubular body 100. The inner partition 110c, which is the inner portion of the partition 110a, is continuous with the inner peripheral surface of the first tubular body 100. The length from the upper end to the lower end of the inner partition wall portion 110c of the partition wall portion 110a is shorter than the length from the upper end to the lower end of the outer partition wall portion 110b.

[0153] The insertion hole 111 is a through hole formed in the axial direction A1. The diameter of the insertion hole 111 is large enough to insert the core material 1. Specifically, the diameter of the insertion hole 111 is approximately the same as or slightly larger than the diameter of the core material 1. The diameter of the insertion hole 111 is shorter than the diameter of the inner circumferential surface of the first tubular body 100. An adhesive member is attached to the inner circumferential surface of the insertion hole 111. The inner circumferential surface of the insertion hole 111 faces the core material 1.

[0154] The inner peripheral surface of the insertion hole 111 faces the core material 1. An adhesive material, which is an elastic adhesive, is applied to the inner peripheral surface of the insertion hole 111 to adhere to the core material 1. However, this is not limited to this. The adhesive material applied to the inner peripheral surface of the insertion hole 111 may be a soft adhesive material that is flexible enough to not peel off even when the adhesive surface is bent. The length of the inner peripheral surface of the insertion hole 111 in the axial direction A1 is d2. The length d2 of the inner peripheral surface of the insertion hole 111 is shorter than the maximum length D3 of the partition wall portion 110a in the axial direction A1. Therefore, when the core material 1 is bent, the area where the inner peripheral surface of the insertion hole 111 presses the core material 1 is reduced, and the load on the first tubular body 100 is reduced. Furthermore, since the volume of the partition wall portion 110a is reduced, the first tubular body 100 can be made lighter.

[0155] Other embodiments Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments.

[0156] For example, in the first and 15 embodiments, on the -Y side of the first tubular body 100, the first opposing surface 11b of the axial hole 11 or the second opposing surface 111b of the insertion hole 111 is fixed to the core material 1 with an adhesive. However, this is not limited to this. When the core material 1 is fixed to the first tubular body 100 with the part 3 on the +Y side of the first tubular body 100, the diameter of the axial hole 11 or the insertion hole 111 may be larger than the diameter of the core material 1. When the core material 1 is bent, the range of motion of the core material 1 is increased, which reduces the load on the connection part 10 or the first tubular body 100 and makes the connection part 10 or the first tubular body 100 less likely to be damaged.

[0157] In the first embodiment, the component 3 is attached to the -Y side end of the first tubular body 100 and the +Y side end of the first tubular body 100. However, this is not limited to this. The component 3 may be attached to one of the -Y side end of the first tubular body 100 and the +Y side end of the first tubular body 100, and a bushing may be attached to the other.

[0158] In the thirteenth and fourteenth embodiments, the component 3 according to the first, second, or fifth embodiment is inserted into the insertion portion 112 or the insertion groove 113. However, this is not limited to this. The component 3 according to the third, fourth, or sixth to eleventh embodiment may also be inserted into the insertion portion 112 or the insertion groove 113.

[0159] The present invention allows various embodiments and modifications without departing from the broad spirit and scope of the present invention. The above-described embodiments are for the purpose of explaining the present invention and are not intended to limit the scope of the present invention. [Explanation of symbols]
