  As described above, the cord-like body held by the cord-like body holding tool is not always stationary during use, and depending on its use, it may be moved greatly while being held by the cord-like body holding tool. is there. For example, the partition wall 100 shown in FIGS. 16 and 17 is a floor plate constituting the floor of the cab of the work machine, and the cord 110 is disposed outside the cab and the inside of the cab. When the control box is slidable in the front-rear direction on the floor plate, the pipe is connected to a valve (for example, a pilot valve) included in the control box disposed in the The cord 110, which is the hydraulic pipe, is greatly shaken in the front-rear direction. In this regard, the conventional 80 and 90 shown in FIGS. 16 and 17 have the following problems to be solved.

  First, the holder 90 shown in FIG. 17 can stably hold the cord 110 in a state of being fixed to the partition wall 100, but on the other hand, the cord-like body 110 with respect to the partition wall 100. In order to fix the angle to a specific angle (generally 90 °), each of the cords 110 is swung in a direction along the partition wall 100 (vertical direction in FIG. 17) as shown by a two-dot chain line in FIG. Accordingly, the cord 110 is subjected to bending deformation with a high curvature (that is, with a small curvature radius). When such a bending with a high curvature is repeatedly applied to the cord-like body 110, the cord-like body 110 or the holder 90 holding the cord 110 may be damaged.

  On the other hand, in the holder 80 shown in FIG. 16, since the bending deformation of the intermediate portion 86 of the grommet 82 allows the relative displacement of the partition plate 82 with respect to the partition wall 100, even if some fluctuation occurs in the cord-like body 110. When the partition plate 82 follows this, bending deformation with a high curvature of the cord 110 can be avoided. However, the partition plate 82 is located at a position that is highly separated from the partition wall 100 with the intermediate portion 86 therebetween, and is moved to the same extent as the deflection of the cord-like body 110 at that position. It is difficult to hold each cord 110 in a stable state.

  The present invention relates to a cord-like body holder for holding a cord-like body inserted through the through-hole while closing the through-hole provided in the partition wall of the work machine, and stably holding the cord-like body It is another object of the present invention to provide a machine that can flexibly allow the movement of the cord-like body and a work machine equipped with the cord-like holder.

  The cord holder provided by the present invention is made of an elastic material, and has an entire circumference around the inner peripheral surface of the insertion hole surrounding the cord insertion hole through which the cord can be inserted and the peripheral portion of the through hole of the partition wall. A grommet having a sealing surface that can be closely attached to the partition wall, and a fixture that fixes the grommet to the partition wall while closely contacting the seal surface to a peripheral portion of the through hole of the partition wall. The grommet has a cable body holding portion that has the insertion hole inner peripheral surface and holds the cable body inserted through the cable body insertion hole, and surrounds the cable body holding portion and the seal surface A fixing portion fixed to the partition wall in a state where the seal surface is in close contact with the partition wall, and continuously interposed over the entire circumference between the cord-like body holding portion and the fixing portion. A connecting portion that connects the cord-like body holding portion and the fixing portion to each other within a region inside the rod-like body holding portion. The connecting portion is configured such that the cord-like body holding portion is in the region inside the fixing portion, and the reference is viewed from a specific reference direction in a direction orthogonal to the normal direction of the seal surface with respect to the fixing portion. And a shape that can be elastically deformed so as to allow tilting in an allowable tilting direction orthogonal to both the direction and the normal direction.

  According to this cord-like body holding tool, the cord-like body can be closed while the cord-like body is inserted into the through-hole while the cord-like body is held, and the cord-like body can be stably held. It is possible to flexibly tolerate the inclination of the cord-like body with respect to the partition wall. Specifically, in the state where the fixing portion is fixed to the partition so that the sealing surface of the fixing portion in the grommet is in close contact with the peripheral portion of the through hole in the partition, The cord-like body inserted through the body insertion hole can be held. Further, the connecting portion is continuously interposed over the entire circumference between the cord holding portion and the fixing portion, thereby closing the through hole in the entire grommet together with the cord holding portion and the fixing portion. The cable-shaped body held by the cable-shaped body holding part can be elastically deformed so as to allow the inclination of the cable-shaped body holding part with respect to the fixed part. It is possible to flexibly allow tilting in the tilting allowable direction with respect to the partition wall on which the fixing portion is fixed. In addition, the cord-like body holding portion allows the inclination of the cord-like body by tilting in the region inside the fixing portion while being accompanied by elastic deformation of the connecting portion. Compared with the one in which the partition plate 81 holds the cord-like body 100 at a position far away from the partition wall and the base portion 85 fixed to the partition wall, such as the holder 80, it is stable while allowing the inclination of the cord-like body. Holding can be performed.

  Here, “the cord holding part is tilted in the area inside the fixing part” means that the entire cord holding part is in the area inside the fixing part up to the normal direction of the seal surface. Is not intended to limit the cable body to be completely accommodated in the normal direction, and the cord body holding portion is included in a state in which at least a part of the cord body holding portion is included in the region inside the fixing portion in the normal direction. This is intended to include all aspects in which the inclination of is allowed.

The connecting portion has a thin-walled portion that can be bent and deformed in regions located on both sides of the cable-shaped body holding portion in at least the inclination-allowing direction of the connecting portion, and the bending-permitting is allowed by the deformation of the thin-walled portion. It permits the inclination of the cord-like body holding portion in the direction.

In the first invention of this application, further the thin portion extends along the normal direction of the sealing surface, of the wick member holding portion to the fixed portion by bending deformation in a direction perpendicular thereto It allows the slope. This shape allows the thin-walled portion to bend and deform so as to allow the inclination of the cable-shaped body holding part within a limited area between the cable-shaped body holding part and the fixing part surrounding the cable-shaped body holding part. . In other words, it is possible to allow the inclination of the cable-shaped body holding part while suppressing the distance between the cable-shaped body holding part and the fixed part and avoiding an increase in the size of the grommet.

In the second invention of this application, further, both outer portions of the cord-shaped body holding portion in the reference direction of the connecting portion constitute a thick portion that is thicker than the thin portion, and inclination of the cord-like holding member by a combination of the torsional deformation of the thick portions and the bending deformation of the thin portion its permissible operating. The combination of the thin part and the thick part makes it possible to limit the direction in which the cord holding part is inclined to the inclination allowable direction. In other words, it is possible to suppress the cord-like body holding portion from being inclined in the reference direction.

In the third invention of this application, further, at least one of the portions of the fixed portion located on both sides of the cord-shaped body holding portion with respect to the reference direction is the cord-shaped body with respect to the tilt allowable direction of the fixed portion. By having an inclination restricting portion protruding in a direction away from the sealing surface than the portions located on both sides of the holding portion, the inclination restricting portion abuts on the cord-like body or a portion of the grommet inclined together with the cord-like body. It regulates the inclination of the wick member to the reference direction. This inclination regulating part can also limit the inclination direction of the cord holding part to the inclination allowable direction by suppressing the cord holding part and the cord holding part held by the inclination restricting part from inclining in the reference direction. To.

The cord holder according to the fourth invention of the present application further clamps the grommet from both outer sides in the reference direction so that the inner peripheral surface of the cord holder holds the cord. Ru Bei clamp member to elastically deform so as to be in close contact with the outer peripheral surface of e. The clamp member can more reliably hold the cord-like body by the cord-like body holding portion by promoting close contact between the inner circumference surface of the cord-like body holding portion and the outer circumference surface of the cord-like body. it can. In addition, since the direction in which the clamp member clamps the grommet is the reference direction, that is, the direction orthogonal to the allowable tilt direction, the external force for the clamp is applied to the inclination of the cable-shaped body holding portion in the allowable tilt direction. The applied resistance can be kept small.

  Furthermore, in the cord-like body holder that includes the clamp member and the fixing portion has the tilt regulating portion, the clamp member is located further outside the tilt regulating portion and the tilt regulating portion is moved from the outside. By having an inclination restriction reinforcing portion that reinforces the inclination restriction portion by supporting it, it becomes possible to more reliably restrict the inclination of the cord-like body in the reference direction.

  Further, in the cord-like body holder provided with the clamp member, the fastening portion connected to the clamp member so that the fixture is integrally displaced with the clamp member, and the fastening portion and the partition wall are sealed. It is preferable to include a fastener that fastens the grommet to the partition while the seal surface is in close contact with the partition by fastening in a direction along the normal direction of the surface. The combination of the clamp member and the fastened portion makes it possible to realize both the clamping of the grommet and the fixing to the partition wall with a small number of parts.

  Further, the present invention is a work machine, a cab, a floor plate of the cab and a floor plate that forms a partition that separates the inside and the outside of the cab and has a through hole, A seat installed on the floor plate in the cab so as to be movable in a specific seat movement direction along the floor plate, a seat side device provided to move integrally with the seat, and the cab An external device provided outside, a cable-like body arranged to connect the sheet-side device and the external device through a through hole of the floor plate, and the cable-like body holding tool.

  In this work machine, as the seat and the seat side device move in the seat moving direction in the driver's cab, a cord-like body that connects the seat side device and an external device outside the driver's cab is the seat. The grommet is allowed to tilt in the grommet with respect to the cable body holding portion and the cable body held by the cable body holding portion in the tilt allowable direction that matches the sheet moving direction. Further, it is possible to suppress damage to the cords or the grommets holding the cords due to the deflection of the cords.

  As described above, according to the present invention, there is provided a cord-like body holding tool for holding a cord-like body inserted through the through-hole while closing the through-hole provided in the partition wall of the cab of the work machine. A cord capable of flexibly allowing movement of the cord-like body while stably holding the cord-like body, and the cord-like cord holder having the cord-like cord holder functioning effectively A work machine is provided.

  Preferred embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 shows a main part of a work machine in which a cord-like holder according to an embodiment of the present invention is used. The work machine includes a swivel frame 2, a cab 4 mounted on the swivel frame 2, and a control valve 6. The cab 4 is surrounded by a plurality of partition walls, and the interior and the exterior of the cab 4 are separated by the partition walls. The control valve 6 is a hydraulic device mounted on the revolving frame 2 at a position behind the cab 4. The control valve 6 corresponds to an external device provided outside the cab 4.

  In the driver's cab 4, a seat base 11, a seat 17 that is a driver's seat, and a slide mechanism 12 are provided. The seat 17 is installed on the seat base 11. The slide mechanism 12 is interposed between the seat 17 and the seat base 11, and the seat 17 moves in a specific sheet moving direction with respect to the seat base 11, in this embodiment, the front-rear direction of the work machine. The sheet 17 and the sheet base 11 are coupled so as to be able to slide. Specifically, the sheet 17 is allowed to slide between a front end position shown in FIG. 2 and a rear end position shown in FIG.

  A control box 13 is attached to the seat 17 so as to slide integrally therewith. The control box 13 includes an operation lever 14 that can be rotated, and a pilot valve 15 that is a seat-side device that outputs a pilot pressure in response to the operation of the operation lever 14. The pilot valve 15 is connected to the control valve 6 through a plurality of hydraulic pipes 16 each constituting a cord-like body. The hydraulic piping 16 according to this embodiment is made of a material that is flexible and relatively flexible, such as a rubber hose.

  Since the pilot valve 15 is in the cab 4 and the control valve 6 is behind or outside the cab 4, the hydraulic pipe 16 connecting them to each other passes through the partition wall of the cab 4. Routed. In this embodiment, a through hole 18 is provided in the floor plate 10 constituting the floor of the cab 4 in the partition, and the hydraulic pipe 16 is inserted into the through hole 18 so that the cab 4 is inserted. It is routed across the country. Accordingly, as the seat 17 and the control box 13 attached thereto slide and move in the front-rear direction between the front end position shown in FIG. 2 and the rear end position shown in FIG. As shown in FIG. 3, the hydraulic pipes 16 are bent and deformed so as to be swung in the front-rear direction, and the inclination of the hydraulic pipes 16 with respect to the floor plate 10 changes.

  This work machine further includes a holder HD corresponding to the cord-like holder according to the present invention. The holder HD holds the hydraulic pipe 16 in a state of being fixed on the floor plate 10, and closes the inside of the cab 4 by closing the through hole 18.

  Note that the cords held by the cord holder according to the present invention are not limited to the hydraulic pipe 16. The cable-like body may be any cable as long as it is routed through the partition wall of the cab, and may be, for example, another hydraulic pipe, a water pipe, or a cable for electrical connection. Moreover, the partition to which the cord-shaped body holder according to the present invention is fixed is not limited to the floor plate 10 but may be another partition, for example, a side wall that surrounds the cab from the side.

  The holder HD according to the embodiment includes a grommet 20 as shown in FIGS. 4 to 14, a clamp portion, and a fixture. The clamp part includes a first clamp member 30A and a second clamp member 30B, and the fixture includes a fastened part 38, and a bolt 44 and a nut 46, which are fasteners.

  The grommet 20 is formed of an elastic material such as rubber, and includes a pipe holding portion 22 corresponding to a cord-like body holding portion, a fixing portion 23 fixed to the floor plate 10, and a connecting portion 25. Have.

  The pipe holding part 22 is a part that comes into direct contact with and holds the respective hydraulic pipes 16 and has a block shape, here a substantially rectangular parallelepiped shape. A plurality of pipe insertion holes 21 are formed so as to penetrate the pipe holding part 22 along the vertical direction (the normal direction of the seal surface in the present invention). Each has an inner peripheral surface surrounding it. The hydraulic piping 16 can be inserted into each piping insertion hole 21, and the diameter of the piping insertion hole 21 can be in close contact with the outer peripheral surface of the hydraulic piping 16 to be inserted therethrough. In addition, the outer diameter of the hydraulic pipe 16 is set to be approximately the same.

  The number and arrangement of the pipe insertion holes 21 are not limited, but in this embodiment, the pipe insertion holes 21 are respectively formed at a total of six locations. Specifically, each pipe insertion hole 21 is arranged across two rows that are in the horizontal direction along the floor plate 10 and are arranged in the first arrangement direction indicated by the arrow A1 in FIG. 4, and each row has three pipe insertion holes. 21 and the pipe insertion holes 21 in each row are arranged in the horizontal direction perpendicular to the first arrangement direction and in the second arrangement direction indicated by the arrow A2 in FIG.

  The fixing part 23 has a frame shape surrounding the pipe holding part 22 at a predetermined small distance from the outer peripheral surface of the pipe holding part 22, and is integrally connected to the pipe holding part 22 via the connecting part 25. . In other words, the fixing portion 23 surrounds the wiring area of the hydraulic pipe 16. The fixing portion 23 has a flat lower surface, and the lower surface constitutes a seal surface 23 a that can be in close contact with the upper surface of the peripheral edge of the through hole 18 in the floor plate 10 over the entire circumference. The seal surface 23 a may be continuous over the entire circumference so as to surround the through hole 18, and may be configured only by a part of the lower surface of the fixing portion 23 within a range satisfying this condition. Of the lower end portion of the fixing portion 23, the portions positioned on both outer sides of the tilt allowable direction corresponding to the second arrangement direction (the longitudinal direction of the work machine as will be described later) are orthogonal to the seal surface 23 a. It protrudes outward along the inclination allowable direction, and this protruding portion constitutes a displacement restricting protrusion 23b.

  The fixing portion 23 further includes a pair of positioning portions 23d. These positioning portions 23d are portions that protrude downward from the seal surface 23a, and are portions that allow rough positioning of the grommet 20 with respect to the floor plate 10 by being loosely fitted into the through holes 18. .

  The pipe holding part 22 according to this embodiment includes a contact blocking part 24. The contact blocking part 24 is a part for blocking each hydraulic pipe 16 held by the pipe holding part 22 from contacting the first and second clamp members 30A, 30B. Specifically, the contact blocking portion 24 rises upward from the peripheral portion of the pipe holding portion 22, that is, away from the seal surface 23 a, and has a shape surrounding each hydraulic pipe 16 held by the pipe holding portion 22. .

  While the connecting portion 25 is interposed over the entire circumference between the pipe holding portion 22 and the fixing portion 23, the pipe holding portion 22 and the fixing portion 23 are mutually connected in a region inside the fixing portion 23. It is a part to connect. Therefore, the connecting portion 25 can completely block the through hole 18 in cooperation with the pipe holding portion 22 and the fixing portion 23.

  As a feature of the holder HD, the connecting portion 25 is configured such that the pipe holding portion 22 is fixed in the direction perpendicular to the normal direction of the seal surface and viewed from a reference direction parallel to the first arrangement direction. It has a shape that can be elastically deformed so as to allow tilting in the tilt allowable direction orthogonal to the reference direction within the region inside the portion 23. The reference direction is a direction indicated by an arrow A1 in FIG. 4, and is a vertical direction on the paper surface in FIGS. 5 and 7, and a depth direction on the paper surface in FIGS. The tilt allowable direction is a direction parallel to the second arrangement direction indicated by an arrow A2 in FIG. 4 and is a direction orthogonal to both the normal direction of the seal surface 23a and the reference direction. In FIGS. 5 to 7 and 9, it is the left-right direction on the paper.

  Here, the positioning portion 23d is loosely fitted inside the through hole 18, so that the reference direction of the grommet 20 is matched with the horizontal direction of the work machine, that is, the direction orthogonal to the moving direction of the seat 17, The position of the positioning portion 23d is set so that the tilt allowable direction matches the front-rear direction of the work machine, that is, the direction parallel to the moving direction of the seat 17. That is, the holder HD according to this embodiment is designed to be installed on the work machine so that the allowable tilting direction matches the front-rear direction of the work machine and the reference direction matches the left-right direction of the work machine. Has been.

  Regarding the connecting portion 25, “allowing the pipe holding portion 22 to tilt within the region inside the fixing portion 23” means that the pipe holding portion 22 as a whole is fixed in the vertical direction, which is the normal direction of the seal surface. It is not intended to limit that it is completely contained in the region inside the portion 23, but in a state where at least a part of the pipe holding portion 22 is included in the region inside the fixed portion 23 in the vertical direction. This is intended to include all aspects in which the inclination of the pipe holding portion 22 is allowed. Therefore, the pipe holding part 22 is not limited to the one completely accommodated inside the fixing part 23 in the vertical direction as shown in FIG. 9. For example, the lower end of the pipe holding part 22 is lower than the lower end of the fixing part 23. The upper end of the pipe holding part 22 may protrude beyond the upper end of the fixed part 23.

  Specifically, the shape of the connecting portion 25 partially includes a thin portion 25a as shown in FIG. As shown in FIG. 7, the thin portion 25a extends in the vertical direction, that is, the direction along the normal direction of the seal surface 23a, and has a shape in which the thickness direction is orthogonal to the normal direction. Specifically, the thin portion 25 a has a shape that extends upward from the lower end of the inner surface of the fixed portion 23 along the normal direction of the seal surface 23 a and is connected to the outer surface of the pipe holding portion 22. As shown in FIGS. 13 and 14, the thin portion 25a is bent and deformed in the thickness direction of the thin portion 25a, thereby allowing the pipe holding portion 22 to be inclined with respect to the fixing portion 23 in the bending direction.

  A pair of grooves 27 that open downward as shown in FIGS. 7 and 9 are formed in the connecting portion 25, and a portion of the connecting portion 25 that is located just outside the grooves 27 has the thin-walled portion 25 a. It is composed. That is, the region where each groove 27 is formed coincides with the region where the thin portion 25 a exists in the connecting portion 25.

  In this embodiment, as shown in FIG. 7, the regions where the grooves 27 are formed are respectively located on both outer sides of the pipe holding portion 22 in the tilting allowable direction (left and right direction in FIG. 7) of the connecting portion 25. It is a pair of area | region including the part to locate. Specifically, each groove 27 includes a first portion 27a extending in the reference direction (vertical direction in FIG. 7) perpendicular to the allowable tilt direction on both outer sides of the pipe holding portion 22 with respect to the allowable tilt direction, and a first portion 27a. A pair of second portions 27b extending inwardly from both ends of the portion 27a along the tilt allowable direction (the left-right direction in FIG. 7), and the thin portion 25a exists just outside each groove 27. ing. In other words, a portion of the connecting portion 25 where the groove 27 is interrupted, that is, a portion interposed between the second portion 27b of one groove 27 and the second portion 27b of the other groove 27. The portions located on both outer sides of the reference direction (vertical direction in FIG. 7) constitute a thick portion 25b that does not have the thin portion 25a and has a larger thickness than the thin portion 25. .

  The shape of the connecting part 25 in which the thin part 25a and the thick part 25b are mixed makes it possible to limit the direction in which the inclination of the pipe holding part 22 with respect to the fixing part 23 is allowed to the inclination allowable direction. To do. Specifically, the inclination of the pipe holding part 22 in the allowable inclination direction is allowed by a combination of the deformation of the thin part 25a in the allowable inclination direction and the torsional deformation of the thick part 25b. The inclination of the pipe holding part 22 in the reference direction, which is the direction in which the both thick parts 25b are arranged, is hardly allowed. However, the connection part which concerns on this invention is not limited to what has both the said thin part 25a and the said thick part 25b. For example, when it is not necessary to limit the inclination direction of the pipe holding part 22, the thin part 25a may exist over the entire circumference.

  As described above, as a means for limiting the inclination direction of the pipe holding portion 22, the fixing portion 23 has a pair of inclination regulating portions 23c. These inclination regulating portions 23c are portions of the fixing portion 23 that are located on both sides of the pipe holding portion 22 with respect to the reference direction, and of the fixing portion 23, the cord holding portion with respect to the inclination allowable direction. It is a part which protrudes upwards from the part located in the both sides, ie, the direction away from the said seal surface 23a. These inclination restricting portions 23c come into contact with a portion of the grommet 20 that is inclined together with the hydraulic piping 16, specifically, the contact blocking portion 24 included in the piping holding portion 22, thereby the hydraulic piping in the reference direction. 16 inclination is regulated. In addition, the said inclination control part 23c may contact | abut directly to the said hydraulic piping 16 which is a cord-like body, for example, and the inclination may be controlled, when the said contact prevention part 24 does not exist.

  The grommet 20 according to this embodiment is provided with a first cut 26A and a second cut 26B for facilitating the insertion of the hydraulic pipe 16 into each pipe insertion hole 21. These cut lines 26A and 26B are located at the pipe insertion holes 21 located at one outer end of the pipe insertion holes 21 in the respective rows in the pipe holding portion 22 (in FIG. 5 and FIG. 7, at the right end of each row, respectively). All the grommets 20 including the pipe holding part 22, the contact blocking part 24, the connecting part 25, and the fixing part 23 across the pipe insertion hole 21) in the direction along the inclination allowable direction and outside the fixing part 23. A straight line leading to the end.

  Each cut 26A, 26B divides the grommet 20 in a direction perpendicular to the axial direction of the pipe insertion hole 21 and in a direction perpendicular to the direction in which the cuts 26A, 26B extend (reference direction in this embodiment). Is. This division makes it possible to insert the hydraulic pipe 16 into each pipe insertion hole 21 from the side through the division point. The cuts 26A and 26B may be those that completely cross the grommet 20, that is, those that completely divide the grommet 20 into a plurality of portions.

  The cuts 26 </ b> A and 26 </ b> B according to this embodiment are inclined in the reference direction with respect to the axial direction of the pipe insertion hole 21. However, this inclination is not necessarily required. The cuts 26A and 26B themselves can be omitted.

  The first clamp member 30 </ b> A and the second clamp member 30 </ b> B constitute the clamp part, and are clamped together to clamp the grommet 20 from the outside. The clamp part according to this embodiment clamps the grommet 20 from both sides of the reference direction, that is, a direction orthogonal to the tilt allowable direction.

  Specifically, the first clamp member 30A has a flat plate shape that extends in the allowable tilt direction orthogonal to the reference direction, and is in the upright direction with respect to the side surface of the grommet 20 (in the direction of the arrow A1 in FIG. 4). It has a shape that can be contacted from one side of the direction. Bolt insertion holes 32 through which the bolts 40 can be inserted are formed at both ends in the longitudinal direction of the first clamp member 30 </ b> A, and the nuts 42 screwed into the bolts 40 are aligned with the bolt insertion holes 32. Further, the first clamp member 30A is fixed to the outer surface (surface opposite to the surface facing the grommet 20) by welding or the like.

  The second clamp member 30B is similarly plate-shaped and has a band shape surrounding the grommet 20 from the side opposite to the first clamp member 30A. Specifically, the second clamp member 30B integrally includes a clamp plate portion 33, a pair of side plate portions 35 and 35, and a fastening portion 37, and has a uniform height dimension over the entire longitudinal direction thereof (described above). A dimension parallel to the axial direction of the pipe insertion hole 21 and parallel to the normal line of the seal surface 23a).

  The clamp plate portion 33 is a portion extending in a direction parallel to the first clamp member 30A, that is, a direction parallel to the tilt allowable direction, and the grommet 20 is upright from a side opposite to the first clamp member 30A. It has a shape that can contact the side surface. The both side plate portions 35, 35 pass from both ends of the clamp plate portion 33 along both sides of the grommet 20 along a direction parallel to the reference direction, more specifically, both displacements of the fixing portion 23 in the grommet 20. It passes above the restricting protrusion 23b and extends toward the first clamp member 30A. Accordingly, the upper surfaces of both displacement regulating protrusions 23b are in contact with the lower end surfaces of the both side plate portions 35, 35, whereby the second clamp member 30B is displaced downward relative to the grommet 20 (that is, the floor plate 10 which is a partition wall). Relative displacement in the direction of approaching.

  In other words, both displacement restricting protrusions 23b are portions protruding outward from the outer peripheral surface of the pipe holding portion 22 which is a clamped portion clamped by the first and second clamp members 30A and 30B, Positioning of the first and second clamp members 30A and 30B with respect to the grommet 20 and the first and second clamp members by contact between the displacement restricting protrusion 23b and the first and second clamp members 30A and 30B. The regulation of the downward relative displacement of the grommets 20 of 30A and 30B is realized.

  Each fastening portion 37 is a portion fastened to the first clamp member 30 </ b> A, and protrudes outward from an end portion of the both side plate portions 35, 35 opposite to the clamp plate portion 33. To do. These fastening portions 37 are respectively provided with bolt insertion holes 37a, and the bolts 40 are inserted in the bolt insertion holes 37a and the corresponding bolt insertion holes 32 of the first clamp member 30A. Both the fastening portions 37 can be fastened to the first clamp member 30A by being screwed into the nut 42 and tightened.

  Here, the length of the side plate portions 35, that is, the dimension in a direction parallel to the reference direction, is determined by fastening both the fastening portions 37 to the first clamp member 30A. And the first clamp member 30A can clamp the grommets 20 in the first arrangement direction, and each inner periphery of the pipe holding portion 22 of the grommets 20 regardless of the presence of the cuts 26. The grommet 20 is set to a dimension that allows the grommet 20 to be elastically deformed in the compression direction until the surface is in close contact with the outer peripheral surface of each hydraulic pipe 16 over the entire circumference. Moreover, the space | interval between the said side-plate parts 35 and 35, ie, the space | interval of the said inclination tolerance direction, is set slightly larger than the dimension of the grommet 20 of the said direction. This is because the clamp in the reference direction by the first and second clamp members 30A and 30B, that is, the elastic compressive deformation of the grommet 20 in the same direction causes the grommet 20 to expand in a tilt allowable direction orthogonal to the reference direction. In anticipation of allowance for expansion.

  The fastened portion 38 is a portion fastened to the floor plate 10 in the thickness direction of the floor plate 10, that is, the normal direction thereof. In this embodiment, the fastened portion 38 is integrally connected to the first clamp member 30 </ b> A. . The fastened portion 38 extends along with the first clamp member 30A in a direction parallel to the allowable tilting direction, and extends outward from the lower end of the first clamp member 30A (opposite to the grommet 20). That is, the fastened portion 38 according to this embodiment forms an L-shaped cross section that is continuous with the first clamp member 30A. In other words, in this embodiment, the first clamp member 30A and the fastened portion 38 are configured by a single plate member having an L-shaped cross section.

  A plurality of bolt insertion holes 39 arranged along the longitudinal direction are formed in the fastened portion 38. On the other hand, a plurality of bolt insertion holes 19 are formed in the floor plate 10 at positions corresponding to the bolt insertion holes 39, respectively, and the bottom plate of the floor plate 10 is illustrated at positions corresponding to the bolt insertion holes 19, respectively. A nut 46 as shown in Fig. 4 is fixed by welding or the like. A bolt 44 as a fastener is inserted into the bolt insertion hole 39 and the bolt insertion hole 19 from above, and is screwed into the nut 46 to be tightened. Fastened to the floor plate 10 along the vertical direction parallel to the normal line of the seal surface 23a.

  Here, the height dimension of the fixing portion 23 in the grommet 20, that is, the dimension from the upper surface of the displacement restricting protrusion 23 b to the seal surface 23 a in the fixed portion 23 is the upper surface of the displacement restricting protrusion 23 b. The fastening surface 38 is fastened to the floor plate 10 in a state where the lower end surfaces of the both side plate portions 35, 35 of the second clamp member 30B are in contact with each other, and the sealing surface is accompanied by elastic compression deformation of the grommet 20. 23 a is set so as to be pressed against and closely contact the upper surface of the peripheral edge of the through hole 18 in the floor plate 10. Specifically, the height dimension of the displacement regulating protrusion 23b is set to be slightly larger than the vertical distance between the lower end surfaces of the side plate portions 35, 35 and the lower surface of the fixed portion 39.

  It should be noted that the relationship between the fastened part and the clamp part is not limited as long as the fastened part is fastened to the partition wall so as to be integrally displaced with each other so that the sealing surface of the grommet is in close contact with the partition wall. It is not limited to the aspect comprised by a single member like the to-be-fastened part 38 and 30 A of 2nd clamp members. For example, the to-be-fastened part and the clamp part may be connected in such a manner that they cannot be displaced relative to each other using a fastener or other connecting tool.

  Next, the usage procedure and operation of the holder HD will be described. This holder HD can be used, for example, by the following procedure.

  1) Each hydraulic pipe 16 is inserted through the through hole 18 of the floor plate 10 which is a partition wall.

  2) The grommet 20 is opened along the cuts 26A and 26B, and each hydraulic pipe 16 is inserted into each pipe insertion hole 21 from the side, that is, in a direction orthogonal to the axial direction of the hydraulic pipe 16 as shown in FIG. Are inserted from the direction indicated by the arrow A2 (the direction parallel to the allowable tilt direction). As a result, the hydraulic pipe 16 is inserted into each pipe insertion hole 21.

  3) The first clamp member 30 </ b> A and the clamp plate portion 33 of the second clamp member 30 </ b> B are applied to the grommet 20 from both outer sides of the reference direction orthogonal to the tilt allowable direction. Further, the fastening portion 37 of the second clamp member 30B and the first clamp member 30A are fastened by using bolts 40 and nuts 42, which are clamp fasteners. By this fastening, the distance between the first clamp member 30A and the clamp plate portion 33 of the second clamp member 30B is reduced, and the clamping of the grommet 20 in the reference direction is realized.

  The clamp elastically compresses and deforms the grommet 20 so that the inner peripheral surface of the grommet 20, that is, the inner peripheral surface surrounding each pipe insertion hole 21 is brought into close contact with the outer peripheral surface of each hydraulic pipe 16. This close contact ensures the holding of each hydraulic pipe 16 by the pipe holding part 22 of the grommet 20 and enhances the sealing performance between the pipe holding part 22 and each hydraulic pipe 16.

  This clamping is performed at a position where the lower surfaces of the both side plate portions 35, 35 of the second clamp member 30B come into contact with the upper surfaces of both displacement restricting protrusions 23b of the fixing portion 23 of the grommet 20. This abutment more reliably restricts the downward relative displacement of the clamp members 30A and 30B relative to the grommet 20, that is, restricts the relative displacement toward the floor plate 10.

  4) The grommet 20 is placed on the floor plate 10 at a position where the positioning portion 23 d of the grommet 20 is fitted into the through hole 18. As a result, the lower surface of the fixing portion 23 of the grommet 20, that is, the seal surface 23 a is in contact with the entire upper surface of the peripheral portion of the through hole 18 in the floor plate 10. At this time, the allowable inclination direction of the grommet 20 matches the front-rear direction of the work machine, and the reference direction of the grommet 20 matches the left-right direction of the work machine.

  5) In the above state, the fastened portion 38 that is integrally connected to the first clamp member 30A is fastened to the floor plate 10 using the bolts 44 and nuts 46 that are fixing fasteners. By this fastening, the first and second clamp members 30A, 30B are displaced downward, that is, in a direction approaching the floor plate 10, integrally with the fastened portion 38, and both side plate portions 35, 35 of the second clamp member 30B are grommets 20. By pressing the displacement restricting protrusion 23 b of the fixed portion 23 from above, the seal surface 23 a of the fixed portion 23 is brought into close contact with the peripheral portion of the through hole 18 in the floor plate 10. Thereby, installation of the holder HD on the floor plate 10 which is a partition is completed.

  The holder HD can close the through hole 18 while holding the hydraulic pipe 16 in a state where each hydraulic pipe 16 that is a cord-like body is inserted into the through hole 18 of the floor plate 10, and The inclination of the hydraulic pipe 16 with respect to the floor plate 10 can be flexibly allowed while the pipe 16 is stably held.

  Specifically, in a state where the fixing portion 23 is fixed to the floor plate 10 so that the seal surface 23a of the fixing portion 23 in the grommet 20 is in close contact with the peripheral portion of the through hole 18 in the floor plate 10. The pipe holding part 22 can hold each hydraulic pipe 16 which is a cord-like body inserted through the pipe insertion hole 21.

  Further, the connecting portion 25 of the grommet 20 is continuous over the entire circumference between the pipe holding portion 22 and the fixing portion 23, thereby enabling the grommet 20 to close the through hole 18 and fixing the grommet 20. By elastically deforming the pipe holding part 22 with respect to the part 23, the hydraulic pipe 16 held by the pipe holding part 22 is fixed to the fixing part 23 and further to the fixing part 23. It is possible to flexibly allow the floor plate 10 to be tilted in the tilt allowable direction.

  Specifically, in this working machine, the seat 17 shown in FIGS. 1 to 3 and the control box 13 attached thereto are operated between the front end position shown in FIG. 2 and the rear end position shown in FIG. As the machine slides in the front-rear direction, each hydraulic pipe 16 that connects the pilot valve 15 that is a seat-side device included in the control box 13 and the control valve 6 that is an external device greatly swings in the front-rear direction. However, as shown in FIG. 13 and FIG. 14, the pipe holding part 22 that holds the hydraulic pipe 16 following the movement of the hydraulic pipe 16 is fixed by the elastic deformation of the connecting part 25. It is allowed to incline in the front-rear direction, that is, the allowable inclination direction with respect to the portion 23, and this is a damage to the hydraulic pipe 16 and the grommet 20 that holds the hydraulic pipe 16. To enable the avoidance of progress.

  More specifically, the bending portion of each thin portion 25a located on both sides of the pipe holding portion 22 in the allowable inclination direction of the connecting portion 25 and the reference direction orthogonal to the allowable inclination direction. The pipe in which the combination of the thick wall portions 25b located on both sides of the pipe holding portion 22 and the torsional deformation around the rotation axis in the reference direction flexibly follows the movement of the hydraulic pipe 16. The inclination of the holding part 22 with respect to the fixing part 23 is allowed. The combination of the bending deformation of the thin portion 25a and the torsional deformation of the thick portion 25b suppresses the inclination of the pipe holding portion 22 in the reference direction orthogonal to the inclination while allowing the inclination of the pipe holding portion 22 in the allowable inclination direction. Make it possible. That is, the direction in which the inclination of the pipe holding part 22 is allowed can be limited to the allowable inclination direction. Therefore, it is possible to restrict the hydraulic pipe 16 from being swung in the reference direction (outside or inside in the working machine according to this embodiment).

  In addition, the pipe holding part 22 allows the inclination of the hydraulic pipe 16 by inclining within the region inside the fixing part 23 while being accompanied by the elastic deformation of the connecting part 25, and is shown in FIG. Compared with the conventional holding tool 80 in which the partition plate 81 holds the cord-like body 100 at a position far away from the partition wall and the base 85 fixed thereto, the stability of the cord-like body is allowed while allowing the rope-like body to be inclined. Can be held.

  Furthermore, in the holder HD according to this embodiment, portions of the fixing portion 23 that are located on both sides of the pipe holding portion 22 with respect to the reference direction are the pipe holding portion with respect to the tilt allowable direction of the fixing portion 23. And an inclination restricting portion 23c that protrudes upward (that is, in a direction away from the seal surface) from the portions located on both sides of the contact holding portion 24 included in the pipe holding portion 22. By abutting, the inclination of the hydraulic pipe 16 in the reference direction is regulated. Therefore, this inclination regulating part 23c also makes it possible to limit the inclination direction of the pipe holding part 22 to the allowable inclination direction. These inclination restricting portions 23c may be omitted depending on the specification, or only one of them may be provided.

  On the other hand, in the holder HD according to this embodiment, the first and second clamp members 30A and 30B constituting the clamp portion are fastened to each other in the reference direction, so that the grommet 20 is disposed on both outer sides in the reference direction. And the grommet 20 is elastically deformed so that the inner peripheral surface of the pipe holding portion 22 is in close contact with the outer peripheral surface of the hydraulic pipe 16, and thereby the hydraulic pipe 16 is moved by the pipe holding portion 22. Make retention more certain. In addition, since the direction in which the clamp members 30A and 30B clamp the grommet 20 is the reference direction orthogonal to the inclination allowable direction, the external force for the clamp is inclined by the pipe holding portion 22 in the inclination allowable direction. Can be kept small.

  Furthermore, in the clamp part according to this embodiment, the second clamp member 30B of the first clamp members 30A and 30B constituting the clamp part has an inclination restriction reinforcing part 33a, and the inclination restriction reinforcing part 33a is The inclination restricting portion 23c is reinforced by supporting the inclination restricting portion 23c from the outside located further outside the inclination restricting portion 23c. This makes it possible to more reliably regulate the inclination of the hydraulic pipe 16 in the reference direction (specifically, the outside of the work machine). This inclination restriction reinforcing portion may be omitted, may be provided on the first clamp member 30A, or may be provided on both the first and second clamp members 30A, 30B.

  Further, the fixture of the holder HD according to this embodiment includes a fastened portion 38 connected to the first clamp member 30A so as to be displaced integrally with the first clamp member 30A, the fastened portion 38 and the floor. A fastener for fixing the grommet 20 to the floor plate 10 while the plate 10 is fastened to the floor plate 10 by fastening the plate 10 in a direction along the normal direction of the seal surface 23a. Therefore, it is possible to both clamp the grommet 20 and fix it to the floor plate 10 with a small number of parts.

  In the present invention, the shape of the grommet can be changed as appropriate. For example, the shape of the connecting portion may be any shape that allows the inclination of the cord-like body holding portion with respect to the fixed portion in at least the inclination allowable direction. For example, the connecting portion 25 of the grommet 20 according to the above embodiment has a thin portion 25a extending upward from the fixing portion 23 toward the pipe holding portion 22, but the connecting portion 251 of the grommet 201 shown in FIG. Thus, it may have a thin portion 25 a extending downward from the fixing portion 23 toward the pipe holding portion 22.

  Alternatively, the thin-walled portion according to the present invention extends from the fixed portion toward the cord-shaped body holding portion in parallel with the tilt allowable direction and bends and deforms in the thickness direction, that is, the direction parallel to the normal direction of the seal surface. It may be a thing. However, as shown in FIG. 9 and FIG. 15, the thin portion 25 a extending in the direction parallel to the normal line of the seal surface 23 a is formed between the fixed portion 23 and the pipe holding portion 22 within the region inside the fixed portion 23. A large inclination of the pipe holding part 22 can be allowed while being arranged in a limited space.

  The inclination restricting portion 23c and the positioning portion 23d in the grommet 20 can be omitted as appropriate. Further, the displacement restricting protrusion 23b can be omitted. For example, when the relative displacement of the clamp members 30A and 30B with respect to the grommet 20 (relative displacement in the direction approaching the floor plate 10) can be restricted only by the biting of the first and second clamp members 30A and 30B into the grommet 20. For this, the displacement restricting protrusion 23b is not necessarily required. Alternatively, like the grommet 201 shown in FIG. 15, the lower end of the outer peripheral portion of the fixed portion 23 forms a flange portion 23 f that protrudes outward, and this flange portion 23 f is directly fastened to a partition wall such as the floor plate 10. It may be a thing.
