  By the way, in the above-mentioned patent document 1, since the flexible fluid pipe is bent and arranged at the upper part of the nozzle body, complicated stress is applied to the flexible fluid pipe as the nozzle body advances and retreats, and the nozzle body and its A large space is required between the case of the upper housing and there is a problem that in reality it cannot be made compact.

  Therefore, the present invention has been made to solve such a problem, and it is an object of the present invention to provide a human body local cleaning device that can minimize the occupied space of the flexible fluid pipe and suppress the height of the upper portion of the nozzle body. is there.

According to a first aspect of the present invention, there is provided a human body local washing device including a movement drive unit that can move forward and backward along the upper surface of a housing, a nozzle body disposed in the movement drive unit, and a washing water in the nozzle body. Two U-shaped flexible fluid pipes that are connected to an inlet provided on the side of the movement drive unit and that are engaged with the housing below the movement drive unit. The flexible fluid pipes are juxtaposed to each other and attached to the housing in a state adjacent to each other via a pipe holder, and the inflection points of the juxtaposed flexible fluid pipes follow and move as the nozzle body advances and retreats. In addition, the flexible fluid pipe is engaged with the housing at an intermediate position and has a substantially S-shape .

The flexible fluid pipe of the human body local cleaning device according to claim 2 may be configured to be vertically attached to the pipe line holder.
The flexible fluid pipe of the human body local cleaning device according to claim 3 is configured such that an end portion is connected to the introduction port provided in a side portion of the movement drive unit along a forward and backward direction of the movement drive unit. Good.

According to the present invention, a nozzle body having a movement drive unit that can be expanded and contracted from a housing, an injection port disposed at a lower portion of the movement drive unit, and an introduction port of cleaning water disposed at an upper portion, and one end of the nozzle A flexible fluid pipe connected to the inlet of the nozzle body and having another portion attached to the housing, and supplying cleaning water to the inlet of the nozzle body, the flexible fluid pipe having one end Is connected to an inlet of the nozzle body provided in a planar direction along the upper surface of the housing on which the nozzle body moves, and a flexible fluid pipe is positioned below the plane along the upper surface of the housing on which the nozzle body moves. In addition, by fixing the nozzle body to the housing below the plane along the housing upper surface where the nozzle body moves, it is substantially U-shaped two-dimensionally or three-dimensionally. Because are disposed, wherein the upper portion of the nozzle body possibly flexible fluid tube to move without any, or contact movement inside a casing covering the housing, does not collide. Also, since the nozzle body is curved in a substantially U shape in two or three dimensions, the inflection point moves without stopping at a specific portion as the nozzle body moves, and stress is applied only to a specific position. Since it does not enter, the life can be extended.
Further, if the flexible fluid pipe is substantially S-shaped, there are two inflection points due to repeated inflections on the second floor, and the inflection points that move as the nozzle body moves are dispersed. Therefore, since stress does not enter only at a specific position, the life can be extended.

According to the second aspect of the present invention, when the flexible fluid pipe is vertically attached to the pipe line holder, a plurality of substantially U-shapes are maintained when viewed partially. However, the installation in which the two fluid pipes are vertical makes the two fluid pipes bendable to the left and right around the vertical, so that the inflection is overall and distributed inflection. Therefore, since the stress does not enter only a specific position, the life can be extended.
Moreover, since the flexible fluid pipe of Claim 3 is connected to the introduction port provided in the side part of the movement drive part along the advance and retreat direction of the movement drive part, it is only in a specific position. Since there is no stress, the life can be extended.

FIG. 9 is an enlarged cross-sectional view taken along line ZZ in the plan view (b) of the bidet nozzle body of the human body local cleaning device according to the first embodiment of the present invention.

First, the shower nozzle side as a human body local cleaning device will be described with reference to FIGS. 1, 2, 4 to 7.
1, 2, and 4 to 7, the housing 2 is a gist of the human body local cleaning device 10 according to the first embodiment, and is formed of synthetic resin or aluminum to which various parts can be attached. . The shower motor 11 rotates the pinion 12 that moves the shower nozzle body 20 through one or more gears in the forward or reverse direction, and the rack 21 that meshes with the pinion 12 moves the shower nozzle body 20 in the vertical direction (that Slide in the length direction). That is, the housing 2 is formed with a guide groove (not shown) for guiding the shower nozzle body 20 in the length direction in which the shower nozzle body 20 slides, and the shower nozzle body 20 meshes with the guide groove. The shower nozzle body 20 performs a linear motion along a guide groove (not shown). The shower nozzle body 20 has two surfaces formed by parallel upper and lower opposing surfaces as a linear plane, and a rack 21 is formed on the lower surface thereof. The rack 21 is formed beyond the range in which the shower nozzle body 20 is slid in the vertical direction. As described above, the range in which the rack 21 is disposed on the shower nozzle body 20 forms a moving drive unit 22 that moves the shower nozzle body 20 by rotating the pinion 12 forward or backward.

  By providing a fluid pipe 42 inside the shower nozzle body 20, a first passage 20 a and a second passage 20 b are defined inside the shower nozzle body 20. The base end side of the first passage 20a (second passage 20b) is connected to a discharge port (not shown) of a water channel switching valve 90 that also serves as a flow rate adjustment valve via a port 25a (25b) and a hose 41a (41b). ing. Thus, the hot water pumped to the input port 90a of the water channel switching valve 90 is supplied only to the hose 41a (hose 41a and 41b) and only the port 25a (port 25a and After being introduced into only the first passage 20a (the first passage 20a and the second passage 20b) via 25b), the fuel is injected from the injection guide 37 that wraps with the injection roller 36 toward the collar. By changing the pressure, flow rate and passage of the hot water, the washing area and the ejection height can be changed.

  In addition, in the present embodiment, the movement drive unit 22 has two planes that are parallel planes as rectilinear planes depending on the ease of recognition of the shower nozzle body 20, but at least one plane is required when the present invention is implemented. That is, it is sufficient if the lower surface is a flat surface and the rack 21 is formed using the flat surface. Of course, this plane may have only the root surface between the teeth as a plane. Therefore, the movement drive unit 22 engages with the rack 21 and can be extended and retracted from the housing 2 by the rotation of the pinion 12 fixed to be rotatable.

  Below the movement drive unit 22 of the shower nozzle body 20, there is a small-diameter portion 26 having a diameter smaller than the diameter of the movement drive unit 22 and having a cylindrical outer periphery. An O-ring 27 is disposed near the lower end of the outer periphery of the small diameter portion 26. An engagement piece 28 having a substantially cylindrical shape and a height of about 1 to 3 mm is disposed closer to the movement drive unit 22 than the central portion of the small diameter portion 26. The engagement piece 28 is not limited to a cylindrical shape, and may be a chamfered polygonal column. In any case, it is necessary to have a structure with high mechanical strength.

  The small-diameter portion 26 of the shower nozzle body 20 has a nozzle cover 30 that is mounted so as to cover the small-diameter portion 26. The nozzle cover 30 has an inner diameter that elastically contacts the O-ring 27, and is a length that guides the engagement piece 28 disposed in the small-diameter portion 26 to a predetermined position when the nozzle cover 30 is inserted in the length direction of the shower nozzle body 20. Rotation formed by partially forming a groove having a predetermined width in the rotation direction continuously from the direction guide slit 31 and the length direction guide slit 31 and less than the width of the engagement piece 28 disposed in the small diameter portion 26. A guide slit 33 having a direction guide slit 32 is provided.

  Further, when the longitudinal direction guide slit 31 is rotated from the longitudinal direction guide slit 31 to the rotational direction guide slit 32 in use, engagement with the engaging piece 28 is performed by a snap operation, and the rotational direction guide slit 32 is engaged. It engages with the piece 28. In the present embodiment, the rotation angle of the nozzle cover 30 has an outer shape in which the upper surface of the shower nozzle body 20 is also a flat surface. Therefore, the outer peripheral shape of the movement drive unit 22 of the shower nozzle main body 20 and the outer peripheral shape of the nozzle cover 30 are the same. That is, when the upper plane of the shower nozzle body 20 is coincident with the upper plane of the movement drive unit 22 and the nozzle cover 30, the engagement position is obtained. This can be confirmed visually or by touch.

As shown in FIG. 7, the fluid pipe 42 according to the present embodiment passes through the movement drive unit 22, protrudes from the small diameter portion 26 at the lower end of the movement drive unit 22, and is mounted inside the nozzle cover 30. It is connected to the injection guide 35. An ejection port 36 is provided in the ejection guide 35, and the cleaning water of the fluid pipe 42 is ejected from the ejection port 36 of the ejection guide 35. Note that an ejection guide port 37 of the nozzle cover 30 is located at the ejection port 36 and covers positions other than the ejection port 36.
Therefore, there is a possibility that the nozzle cover 30 may become dirty, but the nozzle cover 30 can always be kept clean by removing the nozzle cover 30 and washing it.

  As described above, the shower nozzle body 20 of the human body local cleaning device 10 according to the present embodiment has one surface as a flat surface, the rack 21 is formed on the flat surface, and the rotation of the pinion 12 that is rotatably fixed and meshes with the rack 21. Thus, the movement drive unit 22 that can be expanded and contracted from the housing 2, a small diameter part 26 that is formed at the tip of the movement drive unit 22 with a diameter smaller than the diameter of the movement drive unit 22, and whose outer periphery is formed into a cylinder, and a small diameter part 26 and an engaging piece 28 disposed on 26. Moreover, it has the movement drive part 22 which can be expanded-contracted from the housing 2, the injection port 36 arrange | positioned under the movement drive part 22, and the inlets 25a and 25b of the washing water arrange | positioned above.

The two inlets 25a and 25b on the upper side of the movement drive unit 22 of the shower nozzle body 20 are:
It extends so as to be parallel to the moving direction of the shower nozzle body 20. The two introduction ports 25a and 25b are parallel to a virtual plane formed by an angle θ formed by the axis of the center of movement of the shower nozzle body 20 with respect to the horizontal plane, that is, a plane along the upper surface of the housing 2. Two inlets 25a and 25b are provided. Of course, the connecting portion of the two fluid pipes 41 connected to the two inlets 25a and 25b is to insert the two flexible fluid pipes 41 along the two inlets 25a and 25b. Thus, the shower nozzle main body 20 is attached in parallel with a plane along the upper surface of the housing 2 formed at an angle θ formed by the axis of the moving center.
In addition, when implementing this invention, the attachment state parallel to the plane along the housing 2 upper surface at this time does not mean parallel to the length direction of the nozzle body 20 for showers, but planar As a result, the shower nozzle body 20 may be opened at a specific angle in the length direction or may be at a right angle. It suffices if the angle is parallel to or less than the axis of the center of the shower nozzle body 20 as viewed from the side.

  The upper ends of the two fluid pipes 41 are attached to the two inlets 25a and 25b, but the opposite sides are bent in a substantially U shape and are relatively below the inlets 25a and 25b. It is attached to the pipe line holder 3 made of a flexible material. In the present embodiment, the attachment height h of the pipe holder 3 is set to h≈H / 2 with respect to the height of the introduction ports 25a and 25b of the normal shower nozzle body 20. The pipe holder 3 is attached so that the two fluid pipes 41 are vertical. The other ends of the two fluid pipes 41 to which the pipe holder 3 is attached are connected to the water path switching valve 90 in a substantially S shape. That is, when viewed partially, a plurality of substantially U shapes are maintained. The attachment in which the two fluid pipes 41 are vertical is such that the two fluid pipes 41 can bend right and left around the vertical. Depending on the length of the fluid pipe 41 of the book, it may be attached to be inclined toward the inflection point a or the inflection point b on the substantially U-shaped side.

  In the retracted state of the shower nozzle body 20, the inflection point a of the two fluid pipes 41 is at the illustrated position, which is a substantially U-shaped inflection point. However, as shown in FIG. 5, in the operation state when the shower nozzle main body 20 moves downward and the cleaning water in the fluid pipe 42 is jetted from the jet port 36 of the jet guide 35, the two fluid pipes 41. The inflection point moves to the inflection point b side on the pipe holder 3 side where the attachment is performed. At this time, the inflection point a and the inflection point b of the two fluid pipes 41 become substantially U-shaped inflection points. A substantially U-shape is maintained in two dimensions or three dimensions.

  The two flexible fluid pipes 41 are connected at one end to the inlets 25a and 25b of the shower nozzle body 20 provided in the plane direction along the upper surface of the housing 2 where the shower nozzle body 20 moves. Fixed to the housing 2 at a lower position than the plane along the upper surface of the housing 2 on which the main body 20 moves, and arranged in a substantially U shape in a two-dimensional or three-dimensional manner such as a plane or a vertical plane. Moreover, the shower nozzle body 20 moves within the range of the inflection point a to the inflection point b without stopping at a specific portion.

Therefore, since the shower nozzle body 20 is fixed to the housing 2 at a position below the plane along the upper surface of the housing 2 to which the shower nozzle body 20 moves, it is arranged in a substantially U shape two-dimensionally or three-dimensionally. The possibility that the two fluid pipes 41 collide with or slide on the inner surface of the casing 1 above the plane along the upper surface of the housing 2 where the shower nozzle body 20 moves can be eliminated. Further, as the shower nozzle body 20 moves up and down, it moves within the range of the inflection point a to the inflection point b without stopping at a specific portion, so that stress is concentrated on only a specific position. Without being distributed, external force is applied and the life of the fluid pipe 41 can be extended.
Here, the casing 1 covers the entire components attached to the housing 2 such as the bidet nozzle body 60 and the fluid pipe 54 as well as the housing 2, the shower nozzle body 20, and the two fluid pipes 41. Depending on the embodiment, other components may be stored.

  Here, the human body local cleaning device 10 according to the present embodiment includes a movement drive unit 22 that can be expanded and contracted from the housing 2, an ejection port 36 disposed below the movement drive unit 22, and washing water disposed above. The shower nozzle body 20 having the inlet ports 25a and 25b, one end of which is connected to the inlet ports 25a and 25b of the shower nozzle body 20, and the other part fixed to the housing 2, and the shower nozzle body And a flexible fluid pipe 41 for supplying washing water to the 20 inlets 25a and 25b. The flexible fluid pipe 41 has a shower provided at one end in a plane direction along the upper surface of the housing 2 to which the shower nozzle body 20 moves. Connected to the inlets 25a, 25b of the nozzle body 20 for the shower and below the plane along the upper surface of the housing 2 to which the nozzle body 20 for the shower moves By fixing to the housing 2, it is arranged two-dimensionally or three-dimensionally in a substantially U shape, and the inflection point moves without stopping at a specific part as the shower nozzle body 20 moves. Is.

  Further, in the shower nozzle body 20 of the human body local cleaning device 10 in the above embodiment, the two introduction ports 25a and 25b are disposed on the upper part of the movement drive unit 22, but the present invention is carried out. In this case, the range of the movement drive unit 22 is not clear, but it may be above the lower end where the rack 21 of the present embodiment is formed. That is, since the flexible fluid pipe 41 can be mounted on the movement drive unit 22 of the shower nozzle body 20, the upper part of the movement drive unit 22 does not mean the upper end of the movement drive unit 22, but the movement drive unit 22. This means the injection port 36 disposed on the lower side and the cleaning water introduction ports 25 a and 25 b disposed on the upper side of the injection port 36.

  According to the human body local cleaning device 10 in the present embodiment, the mobile drive unit 22 that can be expanded and contracted from the housing 2, the spray port 36 that is disposed below the mobile drive unit 22, and the top of the spray port 36 are disposed. Shower nozzle body 20 having cleaning water inlets 25a and 25b, one end connected to inlets 25a and 25b of shower nozzle body 20, and the other part fixed to housing 2, And a flexible fluid pipe 41 for supplying cleaning water to the inlets 25a and 25b of the nozzle body 20, and the flexible fluid pipe 41 has one end in a planar direction along the upper surface of the housing 2 where the shower nozzle body 20 moves. Connected to the inlets 25a and 25b of the provided shower nozzle body 20, along the upper surface of the housing 2 to which the shower nozzle body 20 moves The flexible fluid pipe 41 is located below the surface, and is fixed to the housing 2 below the plane along the upper surface of the housing 2 to which the shower nozzle body 20 moves. Since it is arranged in a U-shape, there is no possibility that the flexible fluid pipe 41 moves to the inner surface of the casing 1 at the upper part of the shower nozzle body 20, and it is substantially U-shaped two-dimensionally or three-dimensionally. Since the inflection point moves without stopping at a specific part as the shower nozzle body 20 moves, the stress is not applied only at a specific position, thus extending the life. can do.

  Moreover, since at least one surface is made flat except for the small-diameter portion 26 of the shower nozzle main body 20 and a rack 21 is formed there, the shower nozzle main body 20 rotates the pinion 12 fixed to the housing 2 rotatably. By this, the housing 2 can be expanded and contracted freely. The distal end of the movement drive unit 22 of the shower nozzle body 20 is formed with a smaller diameter than the movement drive unit 22, and the outer periphery is a small diameter part 26 formed in a cylindrical shape. The nozzle cover 30 that is mounted so as to cover the small-diameter portion 26 of the shower nozzle main body 20 has an inner diameter that elastically contacts the O-ring 27 when inserted in the length direction of the shower nozzle main body 20, and the length direction guide slit 31. Guides the engagement piece 28 disposed in the small diameter portion 26 to a predetermined position. Thereafter, when the engagement piece 28 is guided to the rotation direction guide slit 32 formed continuously from the length direction guide slit 31 and further rotated, a snap operation is performed to engage with the engagement piece 28. At this time, the nozzle cover 30 can recognize that both are locked as a hand sensation by engaging the engagement piece 28 with the engagement piece 28 of the small diameter portion 26 of the shower nozzle body 20 by the snap operation. Also, the position where the position of the engagement piece 28 of the small diameter portion 26 of the shower nozzle body 20 and the position of the rotation direction guide slit 32 after the snap operation of the nozzle cover 30 is in the engaged state where the snap operation is completed. Therefore, the engagement between the shower nozzle body 20 and the nozzle cover 30 can be recognized by visually confirming the position. The nozzle cover 30 has a continuous shape similar to the outer shape in which at least one surface of the shower nozzle body 20 is a flat surface, and can be recognized visually.

Next, the bidet nozzle side as the human body local cleaning device will be described with reference to FIGS. 1, 3, 4, 8 and 9.
1, 3, 4, 8, and 9, the bidet motor 51 rotates the pinion 52 that moves the bidet nozzle body 60, and the bidet nozzle body 60 is moved in the vertical direction by the rack 61 that meshes with the pinion 52. To be moved. The bidet motor 51 rotates the pinion 52 that moves the bidet nozzle body 60 forward or backward via one or more gears, and slides the bidet nozzle body 60 up and down by a rack 61 that meshes with the pinion 52. It is to be moved. In this bidet nozzle body 60, two surfaces formed by upper and lower opposing parallel surfaces are linear planes, and a rack 61 is formed on a lower surface thereof. The rack 61 is formed beyond the range in which the bidet nozzle body 60 is slid in the vertical direction. As described above, the range in which the rack 61 is disposed on the bidet nozzle body 60 forms a movement drive unit 62 that moves the bidet nozzle body 60 by rotating the pinion 52 forward or backward.

  Since the bidet nozzle body 60 is preferably a soft jet as a bidet, unlike the above-described shower nozzle body 20, it is not necessary to reduce the fluid resistance, so one fluid pipe 54 is connected, The upper end of the movement drive unit 62 of the bidet nozzle body 60 is connected via a connection end 65. That is, the bidet nozzle body 60 is provided with one introduction port 55 at the top of the movement drive unit 62 provided with the rack 61, and further, one fluid pipe 54 is connected to the introduction port 55, The cleaning water passage from the water passage switching valve 90 to the bidet nozzle body 60 is used. In the present embodiment, the connection end 65 disposed at the upper end of the movement drive unit 62 to which the flexible fluid pipe 54 is connected forms a flow path for supplying cleaning water via the inside of the movement drive unit 62 directly. doing.

  In the present embodiment, the movement driving unit 62 has two parallel planes as straight planes because of the ease of recognizing the bidet nozzle main body 60, but at least one plane, that is, the lower plane is a plane. The rack 61 may be formed on the plane. Of course, this plane may have only the root surface between the teeth as a plane. Therefore, the movement drive unit 62 is engaged with the rack 61, and can be extended and retracted from the housing 2 by the rotation of the pinion 52 that is rotatably fixed.

  At the lower end of the movement drive unit 62 of the bidet nozzle body 60, there is a small-diameter portion 66 having a diameter smaller than that of the movement drive unit 62 and having an outer periphery formed in a cylindrical shape. An O-ring 67 is disposed near the lower end of the outer periphery of the small diameter portion 66. An engagement piece 68 having a substantially cylindrical shape and a height of about 1 to 3 mm is disposed closer to the movement drive unit 62 than the central portion of the small diameter portion 66. The engagement piece 68 is not limited to a cylindrical shape, and may be a chamfered polygonal column. In any case, it is necessary to have a structure with high mechanical strength. Both are the same as the configuration of the shower nozzle body 20.

  The small-diameter portion 66 of the bidet nozzle main body 60 has a nozzle cover 70 that is mounted so as to cover the small-diameter portion 66. The nozzle cover 70 has an inner diameter that elastically contacts the O-ring 67, and is a length that guides the engagement piece 68 disposed in the small diameter portion 66 to a predetermined position when the nozzle cover 70 is inserted in the length direction of the bidet nozzle body 60. A rotation formed continuously from the direction guide slit 71 and the length direction guide slit 71 to have a predetermined width in the rotation direction and partially formed by a groove having a width equal to or smaller than the width of the engagement piece 68 disposed in the small diameter portion 66. A guide slit 73 having a direction guide slit 72 is provided.

  Further, when the nozzle cover 70 is inserted into the small-diameter portion 66 and rotated from the longitudinal direction guide slit 71 to the rotational direction guide slit 72, a snap operation is performed between the rotational direction guide slit 72 and the engagement piece 68. The rotation direction guide slit 72 is engaged with the engagement piece 68. In the present embodiment, the rotation angle of the nozzle cover 70 has an outer shape in which the upper surface of the bidet nozzle body 60 is also flat. Therefore, the outer peripheral shape of the movement drive unit 62 of the bidet nozzle main body 60 and the outer peripheral shape of the nozzle cover 70. That is, when the upper plane of the bidet nozzle body 60 coincides with the upper plane of the movement drive unit 62 and the nozzle cover 70, the engagement position is obtained. This can be confirmed visually or by touch. Further, the position where the position of the engagement piece 68 of the small diameter portion 66 of the bidet nozzle body 60 and the position of the rotation direction guide slit 72 after the snap operation of the nozzle cover 70 is in the engaged state where the snap operation is completed. Therefore, the engagement between the bidet nozzle body 60 and the nozzle cover 70 can be recognized by visually confirming the position.

  By being connected in this way, the washing water passing through the inside of the movement drive unit 62 is guided to the inside of the nozzle cover 70 connected to the small diameter portion 66 at the lower end of the movement drive unit 62, Injected from a plurality of formed injection ports 76.

  Here, one inlet 55 on the upper side of the movement drive unit 62 of the bidet nozzle body 60 extends so as to be parallel to the moving direction of the bidet nozzle body 60. The introduction port 55 is provided with one introduction port 55 in parallel with a plane along the upper surface of the housing 2 formed at an angle θ formed by a central axis of movement of the bidet nozzle body 60 with respect to a horizontal plane. . Since the connecting portion of one fluid pipe 54 connected to one inlet 55 is naturally one flexible fluid pipe 54 inserted along one inlet 55, the bidet nozzle The mounting state is parallel to a plane along the upper surface of the housing 2 formed at an angle θ formed by the axis of movement of the main body 60.

  The upper end of the fluid pipe 54 is attached to the introduction port 55. However, the fluid pipe 54 is spirally bent and guided to the pipeline guide 4 below the introduction port 55. Being guided by the pipe guide 4 prevents a part of the flexible fluid pipe 54 wound spirally from being separated from the pipe guide 4. In the present embodiment, the other end of the flexible fluid pipe 54 is connected to the water channel switching valve 90. That is, when viewed partially, a plurality of substantially U shapes are maintained.

  In the retracted state of the bidet nozzle body 60, the inflection point of the fluid pipe 54 changes as a change in the spiral diameter. However, as shown in FIG. 4, in the operation state when the bidet nozzle body 60 moves downward and the washing water of the fluid pipe 54 is jetted from the jet nozzle 76, the inflection point of the fluid pipe 54 is The diameter of the fluid pipe 54 is changed by being regulated by the pipe guide 4 that has been attached, and the entire fluid pipe 54 becomes an inflection point. However, in any state of the bidet nozzle body 60, it is two-dimensionally or three-dimensionally. Maintains a substantially U-shape.

  At this time, one end of the flexible fluid pipe 54 is connected to the inlet 55 of the bidet nozzle body 60 provided in the plane direction along the upper surface of the housing 2 where the bidet nozzle body 60 moves. It is arranged in a substantially U shape two-dimensionally or three-dimensionally by being attached to the conduit guide 4 of the housing 2 at a lower position than a plane along the upper surface of the housing 2.
