According to this configuration, the gaps between the plurality of electric wires are filled with the sheet material having self-adhesive properties. Thereby, it is possible to suppress liquid such as water from entering the inside of the cylindrical member through the gaps between the plurality of electric wires. Further, the second tape member is wound around the outer periphery of the first end of the cylindrical member and the outer periphery of the portion of the first tape member disposed outside the cylindrical member. This second tape member can close the gap between the inner peripheral surface of the cylindrical member and the outer peripheral surface of the first tape member. Therefore, it is possible to suppress the liquid from entering the inside of the cylindrical member through the gap between the inner circumferential surface of the cylindrical member and the outer circumferential surface of the first tape member. Furthermore, the sheet material functioning as a waterproof member is wound around the outer periphery of the electric wire member, and the second tape member functioning as a waterproof member is wound around the outer periphery of the cylindrical member and the outer periphery of the first tape member. . Therefore, compared to the conventional configuration in which a grommet is provided on the outside of the exterior member, it is possible to suppress the overall size of the wire harness from increasing. Therefore, while maintaining waterproof performance, it is possible to suitably suppress the increase in size of the wire harness. Note that the term "cylindrical" in this specification includes not only one in which a peripheral wall is continuously formed over the entire circumferential direction, but also one in which a plurality of parts are combined to form a cylindrical shape. In this specification, "cylindrical" includes those with a circular outer edge shape, those with a flat outer edge shape, and those with a polygonal outer edge shape, and includes any closed shape whose outer edge shape is connected by a straight line or a curved line. say something.

[2] In the above [1], it is preferable that the second tape member is wound around the outer periphery of the electric wire member at a portion exposed from the cylindrical member and the first tape member.
According to this configuration, the second tape member includes the outer periphery of the first end of the cylindrical member, the outer periphery of the first tape member exposed from the cylindrical member, and the electric wire exposed from the cylindrical member and the first tape member. It is wrapped around the outer circumference of the member. As a result, the entire outer periphery of the first tape member exposed from the cylindrical member is covered with the second tape member, and a maze structure is formed between the first tape member and the second tape member. Therefore, the waterproof property of the second tape member can be improved.

[3] In [1] or [2] above, the outer periphery of the cylindrical member in the portion exposed from the second tape member, the outer periphery of the second tape member, and the portion exposed from the second tape member. It is preferable to further include a third tape member wound around the outer periphery of the electric wire member.

According to this configuration, the third tape member is wound from the outer periphery of the cylindrical member exposed from one end of the second tape member to the outer periphery of the electric wire member exposed from the other end of the second tape member. As a result, the entire outer periphery of the second tape member is covered with the third tape member, and a labyrinth structure is formed between the second tape member and the third tape member. Therefore, the second tape member and the third tape member can suitably suppress liquid from entering the inside of the cylindrical member through the gap between the inner circumferential surface of the cylindrical member and the outer circumferential surface of the first tape member.

[4] The wire harness of the present disclosure includes a cylindrical member, an electric wire member passing through the cylindrical member, a sheet material having self-fusion properties and wound around the outer periphery of the electric wire member, and the sheet material. a first tape member wrapped around the outer periphery of the cylindrical member; a cylindrical holder that fits inside the first axial end of the cylindrical member and surrounds the outer periphery of the first tape member; an outer periphery of the first end of the cylindrical member, an outer periphery of the holder at a portion disposed outside the cylindrical member, and an outer periphery of the first tape member at a portion exposed from the holder or exposed from the holder. a second tape member wrapped around the outer periphery of the electric wire member of the section, the electric wire member having a plurality of electric wires, and the sheet material filling gaps between the plurality of electric wires. The outer circumferential surface of the holder has a lower coefficient of friction than the outer circumferential surface of the first tape member.

According to this configuration, the same effects as in the above [1] can be achieved. Furthermore, the outer circumferential surface of the holder surrounding the outer circumference of the first tape member has a lower coefficient of friction than the outer circumferential surface of the first tape member. Thereby, when inserting the holder into the inside of the cylindrical member, the holder easily slides against the inner circumferential surface of the cylindrical member. Therefore, workability when inserting the holder into the cylindrical member can be improved.

[5] In the above [4], the holder is provided so as to cover the entire outer periphery of the first tape member, and the second tape member is provided so as to cover the entire outer periphery of the first end of the cylindrical member. It is preferable that the electric wire member is wound around an outer periphery of the holder in a portion disposed outside the cylindrical member and an outer periphery of the electric wire member in a portion exposed from the holder.

According to this configuration, the entire first tape member is housed inside the holder. Further, the second tape member is wound around the outer periphery of the first end of the cylindrical member, the outer periphery of the portion of the holder disposed outside the cylindrical member, and the outer periphery of the portion of the electric wire member exposed from the holder. . This second tape member can close the gap between the inner circumferential surface of the cylindrical member and the outer circumferential surface of the holder, and also close the gap between the inner circumferential surface of the holder and the outer circumferential surface of the electric wire member. Can be done. For this reason, liquid may enter the inside of the cylindrical member through the gap between the inner circumferential surface of the cylindrical member and the outer circumferential surface of the holder, and the gap between the inner circumferential surface of the holder and the outer circumferential surface of the electric wire member. can be suppressed.

[6] In the above [4] or [5], the holder has a holder-side first end and a holder-side second end in the axial direction of the holder, and the holder-side first end is The holder-side second end is located outside the cylindrical member, and the holder-side first end is located inside the holder-side second end. It is preferable that the first end on the holder side is formed to become thinner toward the open end.

According to this configuration, the holder-side first end portion, which is the portion of the holder that is first inserted into the inside of the cylindrical member, is formed in a tapered shape. This makes it easier to insert the holder inside the cylindrical member. Therefore, workability when inserting the holder into the inside of the cylindrical member can be improved.

[7] In the above [6], it is preferable that the holder-side second end portion has an engaging portion that engages with an axial end surface of the cylindrical member in the axial direction of the cylindrical member.
According to this configuration, the holder-side second end portion is provided with the engaging portion that engages with the axial end surface of the cylindrical member. Therefore, when inserting the holder into the cylindrical member, the holder can be easily positioned in the axial direction of the cylindrical member. Thereby, workability when inserting the holder into the inside of the cylindrical member can be improved.

[8] In any one of [4] to [7] above, the holder has a first divided body and a second divided body, and the holder has a first divided body and a second divided body. It is preferable that the divided bodies are combined to form a cylindrical shape.

According to this configuration, the holder is formed into a cylindrical shape that surrounds the first tape member by the first divided body and the second divided body. Thereby, even though the holder is cylindrical, the holder is divided into the first divided body and the second divided body, so that the holder can be retrofitted to a wire member or the like. That is, since the holder is divided into the first divided body and the second divided body, for example, after wrapping the sheet material and the first tape member around the outer periphery of the electric wire member, the holder can be attached to the electric wire member. Is possible. As a result, the workability of assembling the wire harness can be improved.

[9] In any one of [1] to [8] above, the first tape member extends the length of the sheet material from the outer periphery of the electric wire member exposed from one end in the length direction of the sheet material. It is preferable that the electric wire member is wound around the outer periphery of the electric wire member exposed from the other end in the width direction.

According to this configuration, the first tape member is wound so as to cover the entire outer periphery of the sheet material. With this first tape member, the sheet material can be suitably protected.
[10] In any one of [1] to [9] above, the plurality of electric wires include a plurality of first electric wires and a second electric wire different from the first electric wire, and the electric wire member , a cylindrical braided member surrounding the outer periphery of the plurality of first electric wires; the sheet material fills a gap between the plurality of first electric wires inside the braided member and connects the braided member and the first electric wires; A first sheet material that fills the gap between the first electric wire, a second sheet material that covers the outer periphery of the braided member, and a third sheet that fills the gap between the second electric wire and the second sheet material. It is preferable that the material is formed integrally with the material.

According to this configuration, the first sheet material fills the gaps between the plurality of first electric wires and the gaps between the braided member and the first electric wires. Moreover, the outer periphery of the braided member is covered with the second sheet material. Furthermore, the third sheet material fills the gap between the second electric wire and the second sheet material. Then, the first sheet material, the second sheet material, and the third sheet material are integrated. These first sheet materials, second sheet materials, and third sheet materials create gaps between the plurality of first electric wires, gaps between the braided member and the first electric wires, and gaps between the second electric wires and the second sheet materials. It is possible to suppress liquid from entering the inside of the cylindrical member through the gap.

[11] In any one of [1] to [10] above, the plurality of electric wires are arranged along a first direction, and the cross-sectional shape of the cylindrical member is perpendicular to the first direction. It is preferable to form a flat shape that is longer in the first direction than in the second direction.

According to this configuration, the cross-sectional shape of the cylindrical member is formed into a flat shape that is long in the first direction in which the plurality of electric wires are lined up. Therefore, the size of the cylindrical member can be reduced in the second direction compared to the case where the dimension along the first direction and the dimension along the second direction in the cross section of the cylindrical member are equal to each other.

In addition, in FIG. 3, in order to make it easy to understand the first sheet material 61, the second sheet material 62, and the third sheet material 63, they are distinguished by solid lines. However, in reality, the interface between the first sheet material 61, the second sheet material 62, and the third sheet material 63 may disappear, and the boundary may not be clear.

(Configuration of first tape member 70)
As shown in FIG. 2, the first tape member 70 is wound around, for example, the outer periphery of the sheet material 60 and the outer periphery of the portion of the electric wire member 20 exposed from the sheet material 60. The first tape member 70 is, for example, from the outer circumferential surface of the electric wire member 20 exposed from one longitudinal end of the sheet material 60 to the outer circumferential surface of the electric wire member 20 exposed from the other longitudinal end of the sheet material 60. Continuously wrapped around the area. The first tape member 70 is formed, for example, to cover the entire outer periphery of the sheet material 60.

The first tape member 70 is, for example, spirally wound around the outer peripheral surfaces of the sheet material 60 and the electric wire member 20, with the adhesive layer facing inward in the radial direction. Although detailed illustrations are omitted in FIGS. 2 and 3, the first tape member 70 is attached to the outer peripheral surfaces of the sheet material 60 and the electric wire member 20, for example, so that the first tape member 70 partially overlaps in the width direction. wrapped in a spiral. That is, the first tape member 70 has an overlap-wound structure. Here, the overlapping winding structure is a structure in which the tape member is spirally wound so that predetermined portions in the width direction of the tape member overlap each other. In an overlap-wound structure, the ratio of the width of the later-wound portion to the total width of the earlier-wound portion is called the wrap margin. As the overlap winding, for example, half-wrap winding in which half of the width of the tape member is overlapped can be adopted. Note that the wrap allowance in half-wrap winding is 1/2. The first tape member 70 of this embodiment has a half-wrap structure.

For example, a part of the first tape member 70 in the length direction is accommodated inside the cylindrical member 50, and the remaining part of the first tape member 70 extends from the first end 51. It is provided so as to be pulled out to the outside of the cylindrical member 50. The first tape member 70 has a function of protecting the sheet material 60, for example. The first tape member 70 has, for example, a function of covering the outer peripheral surface of the adhesive sheet material 60.

The electric wire member 20, sheet material 60, and first tape member 70 described above constitute the insertion member 15 that is inserted into the inside of the cylindrical member 50.
(Configuration of second tape member 80)
The second tape member 80 is wound around the outer periphery of the first end 51 of the cylindrical member 50 and the outer periphery of the first tape member 70 at a portion disposed outside the cylindrical member 50. That is, the second tape member 80 is wound around the outer peripheral surface of the first end 51 and the outer peripheral surface of the first tape member 70 drawn out from the first end 51 to the outside of the cylindrical member 50 . The second tape member 80 is formed to close the gap between the inner peripheral surface of the cylindrical member 50 and the outer peripheral surface of the first tape member 70. The second tape member 80 is a waterproof member that prevents liquid such as water from entering the inside of the cylindrical member 50 through the gap between the inner circumferential surface of the cylindrical member 50 and the outer circumferential surface of the first tape member 70. functions as The second tape member 80 of this embodiment is also wrapped around the outer circumferential surface of the electric wire member 20 in the portion exposed from the first tape member 70. That is, the second tape member 80 of the present embodiment is continuous in the range from the outer peripheral surface of the first end 51 to the outer peripheral surface of the electric wire member 20 exposed from the cylindrical member 50 and the first tape member 70. is wrapped around. The second tape member 80 of this embodiment is formed to cover the entire outer periphery of the first tape member 70 exposed from the cylindrical member 50.

The second tape member 80 is, for example, spirally wound around the outer peripheral surfaces of the cylindrical member 50, the first tape member 70, and the electric wire member 20, with the adhesive layer facing inward in the radial direction. The second tape member 80 has, for example, an overlap-wound structure. The second tape member 80 has, for example, a half-wrap structure in most of the lengthwise direction of the second tape member 80 . For example, a plurality of second tape members 80 are arranged such that the entire width of the second tape member 80 is overlapped at the unrolled portion where the second tape member 80 is unwound from the outer circumferential surface of the cylindrical member 50 to the outer circumferential surface of the first tape member 70. It is wrapped around. That is, the second tape member 80 at the unwinding portion is wound around the outer circumferential surface of the first tape member 70 multiple times by overlapping winding with a wrap margin of 1. In addition, in the overlap winding structure in which the wrap margin is 1, the second tape member 80 is spirally wound around the outer peripheral surface of the first tape member 70.

Here, since there is a step between the outer circumferential surface of the cylindrical member 50 and the outer circumferential surface of the first tape member 70, the second tape member 80 wound around the unwinding portion is wrinkled due to the step. is more likely to occur. When wrinkles occur in the second tape member 80, a gap is created between the outer circumferential surface of the first tape member 70 and the inner circumferential surface of the second tape member 80, and the waterproof property of the second tape member 80 is reduced. On the other hand, since the second tape member 80 is spirally wound multiple times at the unwinding portion, a gap is created between the outer circumferential surface of the first tape member 70 and the inner circumferential surface of the second tape member 80. This can be suitably suppressed.

As shown in FIG. 3, the second tape member 80, for example, covers the entire outer peripheral surface of the cylindrical member 50 in the circumferential direction. For example, the second tape member 80 covers the entire outer peripheral surface of the first tape member 70 in the circumferential direction. The second tape member 80 is formed to close the gap between the inner peripheral surface of the cylindrical member 50 and the outer peripheral surface of the first tape member 70 over the entire circumferential direction. Note that in FIG. 3, illustration of the overlapping winding structure of the second tape member 80 is omitted.

(Configuration of third tape member 90)
As shown in FIG. 2, the third tape member 90 cooperates with the second tape member 80 to close the gap between the inner peripheral surface of the cylindrical member 50 and the outer peripheral surface of the first tape member 70. is formed. The third tape member 90 has an outer periphery of the cylindrical member 50 in a portion exposed from the second tape member 80, an outer periphery of the second tape member 80, and an outer periphery of the electric wire member 20 in a portion exposed from the second tape member 80. wrapped around it. That is, the third tape member 90 includes a wire that is exposed from the outer peripheral surface of the cylindrical member 50 that is exposed from one end of the second tape member 80 in the length direction, and an electric wire that is exposed from the other end of the second tape member 80 in the length direction. It is continuously wound around the outer peripheral surface of the member 20. The third tape member 90 is formed to cover the entire outer periphery of the second tape member 80.

The third tape member 90 is, for example, spirally wound around the outer peripheral surfaces of the cylindrical member 50, the second tape member 80, and the electric wire member 20, with the adhesive layer facing inward in the radial direction. Although detailed illustrations are omitted in FIGS. 2 and 3, the third tape member 90 has, for example, an overlap-wound structure. The third tape member 90 of this embodiment has a half-wrap structure.

In this way, the first end 51 of the cylindrical member 50 is provided with a waterproof structure including the sheet material 60, the first tape member 70, the second tape member 80, and the third tape member 90. Note that the second end 52 of the cylindrical member 50 shown in FIG. 1 may also be provided with a waterproof structure similar to the waterproof structure provided on the first end 51.

(Method for manufacturing wire harness 10)
Next, a method for manufacturing the wire harness 10 will be described.
First, as shown in FIG. 4, an electric wire member 20 having a first electric wire member 30 and a second electric wire member 40 is prepared. At this time, the sheet material 60 before self-fusion is attached to the longitudinally intermediate portion of the electric wire member 20.

As shown in FIG. 5, the sheet material 60 before self-fusion has a first sheet material 61 that surrounds the outer periphery of the plurality of electric wires 31 inside the braided member 35. The sheet material 60 before self-fusion has a second sheet material 62 surrounding the outer periphery of the braided member 35 . The sheet material 60 before self-fusion has a third sheet material 63 that surrounds the outer periphery of the second sheet material 62 and the outer periphery of the electric wire 41 . Note that before self-fusion, the gaps between the plurality of electric wires 31, the gaps between the electric wires 31 and the braided member 35, and the gaps between the braided member 35 and the electric wire 41 are filled with the sheet material 60. Not yet.

Subsequently, by pressing the first sheet material 61, the second sheet material 62, and the third sheet material 63 toward the inside in the radial direction, the first sheet material 61 and the second sheet material 63 are bonded together using their self-fusing properties. The material 62 and the third sheet material 63 are integrated. Thereby, the sheet material 60 shown in FIG. 3 can be formed. That is, the sheet material 60 can be formed to fill the gaps between the plurality of electric wires 31, the gaps between the electric wires 31 and the braided member 35, and the gaps between the braided member 35 and the electric wires 41. For example, when the second sheet material 62 is pressurized toward the braided member 35, the second sheet material 62 enters the mesh 36 of the braided member 35, and the second sheet material 62 connects to the first sheet material 61 through the mesh 36. be integrated. In this step, vibration may be applied to the first sheet material 61, the second sheet material 62, and the third sheet material 63, or the first sheet material 61, the second sheet material 62, and the third sheet material may be vibrated. The material 63 may also be heated.

Next, in the step shown in FIG. 6, the first tape member 70 is wrapped around the outer circumferential surface of the electric wire member 20 and the outer circumferential surface of the sheet material 60. When wrapping the first tape member 70, for example, the first tape member 70 is pulled out from the spiral structure, and the pulled out first tape member 70 is spirally wrapped around the outer peripheral surfaces of the electric wire member 20 and the sheet material 60. wrapped in a shape. As shown in FIG. 7, the first tape member 70 of the present embodiment extends from the outer peripheral surface of the electric wire member 20 exposed from one longitudinal end of the sheet material 60 to the other longitudinal end of the sheet material 60. The wire member 20 is continuously half-wound over the range from the wire member 20 to the exposed outer circumferential surface of the wire member 20. Through the above steps, the insertion member 15 having the electric wire member 20, the sheet material 60, and the first tape member 70 is formed.

Subsequently, in the step shown in FIG. 8, the insertion member 15 is inserted into the inside of the cylindrical member 50. The insertion member 15 is inserted into the cylindrical member 50 such that a portion of the sheet material 60 and the first tape member 70 in the length direction is inserted into the cylindrical member 50 . In the structure of this step, a gap is created between the inner peripheral surface of the cylindrical member 50 and the outer peripheral surface of the insertion member 15, specifically, the outer peripheral surface of the first tape member 70.

Next, the second tape member 80 is wrapped around the outer circumferential surface of the first end 51 of the cylindrical member 50 and the outer circumferential surface of the insertion member 15 pulled out from the first end 51 to the outside of the cylindrical member 50. The second tape member 80 is spirally wound around the outer peripheral surfaces of the cylindrical member 50 and the insertion member 15 along the traveling direction P1 along the length direction of the electric wire member 20. That is, the second tape member 80 extends from the starting end side in the traveling direction P1 (cylindrical member 50 side on the right side in the figure) to the terminal end side in the traveling direction P1 (the right side in the figure) with respect to the outer peripheral surfaces of the cylindrical member 50 and the insertion member 15. It is wound spirally toward the center left side). As shown in FIG. 9, the second tape member 80 of this embodiment includes the wire member 20 exposed from the outer peripheral surface of the first end 51 of the cylindrical member 50 and the first tape member 70. Continuous overlapping winding is applied to the area up to the outer circumferential surface. Through this step, the gap between the inner circumferential surface of the cylindrical member 50 and the outer circumferential surface of the insertion member 15 is closed by the second tape member 80.

Next, in the step shown in FIG. 10, the third tape member 90 is applied to the outer circumferential surface of the cylindrical member 50, the outer circumferential surface of the second tape member 80, and the outer circumferential surface of the electric wire member 20 exposed from the second tape member 80. Wrap it around. Through the above steps, the wire harness 10 of this embodiment can be manufactured.

Next, the effects of this embodiment will be explained.
(1-1) The wire harness 10 includes a cylindrical member 50, an electric wire member 20 that passes through the cylindrical member 50, a sheet material 60 that has self-fusion properties and is wrapped around the outer periphery of the electric wire member 20, The first tape member 70 is wound around the outer periphery of the sheet material 60. The wire harness 10 includes a second tape member wound around the outer periphery of the first end 51 in the axial direction of the cylindrical member 50 and the outer periphery of the first tape member 70 in a portion disposed outside the cylindrical member 50. 80. The sheet material 60 is formed to fill the gaps between the plurality of

electric wires

31 and 41 that the electric wire member 20 has.

According to this configuration, the gap between the plurality of

electric wires

31 and 41 is filled with the sheet material 60 having self-adhesive properties. Thereby, it is possible to suppress liquid such as water from entering the inside of the cylindrical member 50 through the gap between the plurality of

electric wires

31 and 41. Further, the second tape member 80 is wound around the outer periphery of the first end portion 51 of the cylindrical member 50 and the outer periphery of the portion of the first tape member 70 disposed outside the cylindrical member 50. This second tape member 80 can close the gap between the inner peripheral surface of the cylindrical member 50 and the outer peripheral surface of the first tape member 70. Therefore, it is possible to suppress the liquid from entering the inside of the cylindrical member 50 through the gap between the inner circumferential surface of the cylindrical member 50 and the outer circumferential surface of the first tape member 70 . Furthermore, the sheet material 60 functioning as a waterproof member is wound around the outer periphery of the electric wire member 20, and the second tape member 80 functioning as a waterproof member is wrapped around the outer periphery of the cylindrical member 50 and the first tape member 70. It has a structure that can be wrapped around it. Therefore, compared to the conventional configuration in which a grommet is provided on the outside of the exterior member, the size of the entire wire harness 10 can be suppressed from increasing in size. Therefore, while having waterproof performance, it is possible to suitably suppress the increase in the size of the wire harness 10.

(1-2) The second tape member 80 is connected to the outer periphery of the first end 51 of the cylindrical member 50, the outer periphery of the first tape member 70 exposed from the cylindrical member 50, the cylindrical member 50 and the first tape. It is wound around the outer periphery of the electric wire member 20 exposed from the member 70. As a result, the entire outer periphery of the first tape member 70 exposed from the cylindrical member 50 is covered with the second tape member 80, and a maze structure is formed between the first tape member 70 and the second tape member 80. Therefore, the waterproof property of the second tape member 80 can be improved.

(1-3) The third tape member 90 is wound from the outer periphery of the cylindrical member 50 exposed from one end of the second tape member 80 to the outer periphery of the electric wire member 20 exposed from the other end of the second tape member 80. As a result, the entire outer periphery of the second tape member 80 is covered with the third tape member 90, and a maze structure is formed between the second tape member 80 and the third tape member 90. Therefore, the second tape member 80 and the third tape member 90 prevent liquid from entering the inside of the cylindrical member 50 through the gap between the inner circumferential surface of the cylindrical member 50 and the outer circumferential surface of the first tape member 70. This can be suitably suppressed.

(1-4) The first tape member 70 is wound around the sheet material 60 and the electric wire member 20 so as to cover the entire outer periphery of the sheet material 60. With this first tape member 70, the sheet material 60 can be suitably protected. Furthermore, since the outer circumferential surface of the sheet material 60 that serves as the adhesive surface can be covered with the first tape member 70, workability when inserting the electric wire member 20 to which the sheet material 60 is attached into the inside of the cylindrical member 50 can be improved. .

(1-5) The first sheet material 61 fills the gaps between the plurality of electric wires 31 and the gaps between the braided member 35 and the electric wires 31. Furthermore, the outer periphery of the braided member 35 is covered with the second sheet material 62 . Furthermore, the third sheet material 63 fills the gap between the electric wire 41 and the second sheet material 62. Then, the first sheet material 61, the second sheet material 62, and the third sheet material 63 are integrated to form the sheet material 60. These first sheet material 61, second sheet material 62, and third sheet material 63 create gaps between the plurality of electric wires 31, gaps between the braided member 35 and the electric wires 31, and gaps between the electric wires 41 and the second sheet material 62. It is possible to suppress liquid from entering the inside of the cylindrical member 50 through the gap therebetween.

(1-6) The cross-sectional shape of the cylindrical member 50 is formed into a flat shape that is longer in the Y-axis direction (first direction) where the plurality of

electric wires

31 and 41 are lined up than in the Z-axis direction (second direction). Therefore, the size of the cylindrical member 50 in the Z-axis direction can be reduced compared to a case where the dimension along the Y-axis direction and the dimension along the Z-axis direction in the cross section of the cylindrical member 50 are equal to each other.
