Description

[Technical Field]

[0001] The present invention relates to a shackle for a disaster prevention vehicle that is attached to a disaster prevention vehicle used for rescue operations and firefighting operations, and a disaster prevention vehicle equipped with the same. [Background technology]

[0002] Conventionally, there are disaster prevention vehicles that are dispatched for rescue operations and firefighting operations when disasters such as fires, earthquakes, and accidents occur. Among such disaster prevention vehicles, there is one that is equipped with a storage compartment for storing equipment for rescue operations and firefighting operations, and a winch device for rescue operations (see, for example, Patent Document 1). The disaster prevention vehicle of Patent Document 1 is equipped with a winch device located behind the rear wheels of the vehicle and below the side wall of the storage compartment. The wire of this winch device is arranged so as to extend forward of the vehicle toward an external lead-out portion at the front of the vehicle. The external lead-out portion of the wire is also provided at the front of the vehicle.

[0003] The winch device is used, for example, to rescue a person trapped inside a vehicle involved in a traffic accident. In this case, the hook of the wire pulled out from the external pull-out section is hooked to an appropriate location on the vehicle, and the winch device is driven to move the vehicle or expand the space inside the vehicle.

[0004] Conventional disaster prevention vehicles such as those described in Patent Document 1 may be equipped with a disaster prevention vehicle shackle for connecting ropes and hooking. This disaster prevention vehicle shackle can be used when using a winch device. Furthermore, conventional disaster prevention vehicles may have such an external wire lead-out portion and disaster prevention vehicle shackle not only at the front of the vehicle but also at the rear of the vehicle.

[0005] A conventional shackle for a disaster prevention vehicle includes a shackle body formed in a U-shape and having a body hole at each end, and a shackle pin. The shackle for a disaster prevention vehicle is attached to a mounting member provided at the front or rear of the vehicle. Specifically, the mounting member is placed between the ends of the shackle body, and the shackle pin is inserted through the mounting hole and a pair of body holes of the mounting member, thereby blocking the open portion of the shackle body, thereby attaching the shackle for a disaster prevention vehicle to the mounting member. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Japanese Patent Application Publication No. 2023-160375 Summary of the Invention [Problem to be solved by the invention]

[0007] However, in conventional shackles for disaster prevention vehicles, there was no anti-sway mechanism for the shackle body relative to the mounting member. As a result, the shackle body would be violently shaken by the shaking of the body of the disaster prevention vehicle while it was traveling, and the shackle body would sometimes collide with the periphery of the mounting member. This could cause noise or damage to the periphery of the mounting member.

[0008] In addition, in conventional disaster prevention vehicle shackles, the shackle body is always suspended downward from the mounting member due to its own weight. Therefore, when attaching a rope or hooking the shackle body, it is necessary to change the orientation of the shackle body and maintain that position, which is cumbersome. Furthermore, in conventional disaster prevention vehicle shackles, when the load from the rope or hook is applied to the shackle body, high stress is generated in the shackle body and the mounting member, which causes damage to the mounting member and each part of the disaster prevention vehicle shackle.

[0009] The present invention has been made in consideration of the above-mentioned situation, and its purpose is to provide a shackle for a disaster prevention vehicle that does not generate noise while the vehicle is running, is easy to work with, and can suppress damage to each part of the shackle and its surrounding areas, and a disaster prevention vehicle equipped with the same. [Means for solving the problem]

[0010] The inventions disclosed in this specification to solve the above-mentioned problems are configured as follows: That is, a first invention is a shackle for a disaster prevention vehicle that is attached to a mounting member provided on a disaster prevention vehicle, comprising: a shackle body having a curved portion formed in a U-shape, a pair of shanks connected to the curved portion, and body holes formed at each end of the pair of shanks, a shackle bolt that is inserted into the mounting hole of the mounting member and the pair of body holes with the mounting member positioned between the pair of shanks to block an opening formed between the pair of shanks, a nut portion that threads onto the male thread of the shackle bolt in the block state, and an anti-vibration spacer that is fitted onto the shackle bolt and is positioned between the pair of shanks and the mounting member, the anti-vibration spacer being formed from a flexible member and configured to prevent the shackle body from swinging relative to the mounting member by tightening the nut portion in the block state.

[0011] According to the first aspect of the present invention, flexible anti-vibration spacers are disposed between both ends of the shackle body and the mounting member. The anti-vibration spacers are configured to prevent the shackle body from vibrating relative to the mounting member by tightening the nut while the shackle bolt is in a disconnected state. As a result, the anti-vibration spacers are sandwiched between the mounting member and both ends of the shackle body. Furthermore, when attempting to rotate the shackle body around the axis of the shackle bolt, large frictional forces can be generated between the mounting member and the anti-vibration spacers, and between both ends of the shackle body and the anti-vibration spacers. This prevents the shackle body from being violently shaken even if the body of the disaster prevention vehicle shakes while traveling. This prevents the shackle body from colliding with the periphery of the mounting member while the vehicle is traveling, thereby preventing noise and damage to the periphery of the mounting member.

[0012] In addition, since a large frictional force can be generated between the mounting member and the anti-vibration spacer, and between both ends of the shackle body and the anti-vibration spacer, when the shackle body is stopped at a desired rotation angle relative to the mounting member, it can self-maintain that position. This makes it easy to attach a rope to the shackle body or to attach a hook, making it easy to work with.

[0013] Furthermore, because flexible anti-vibration spacers are disposed between both ends of the shackle body and the mounting member, when the shackle body is pulled by the rope connected to the shackle body, both ends of the shackle body can flex flexibly in the axial direction of the shackle bolt. Furthermore, even if the orientation of both ends of the shackle body changes relative to the axial direction of the shackle bolt, the anti-vibration spacers can flexibly deform. This makes it possible to suppress the force moment generated at both ends of the shackle body. This also makes it possible to suppress the generation of stress due to the force moment at the center of the shackle body. As a result, damage to the shackle body can be suppressed. It is possible.

[0014] The second invention is a disaster prevention vehicle equipped with the shackle for a disaster prevention vehicle of the first invention, comprising a chassis frame extending in the fore-and-aft direction of the vehicle and a mounting base fixed to the end of the chassis frame in the fore-and-aft direction of the vehicle, wherein the mounting member has the mounting hole portion and the fastening hole portion and is formed in a strip shape, the mounting hole portion is provided at one end of the mounting member, the mounting member is positioned so that the mounting hole portion and its surrounding area are exposed to the outside of the vehicle and the fastening hole portion is located inside the vehicle, and is attached to the mounting base by a fastening member inserted through the fastening hole portion.

[0015] According to the second aspect of the present invention, the shackle for a disaster prevention vehicle can be fixed using a chassis frame with high strength. In addition, the fastening portion of the mounting member to the mounting base is hidden inside the vehicle, which improves the appearance of the vehicle.

[0016] The third invention is characterized in that, in the second invention, a winch device is provided having an external wire pull-out portion at the front end and / or rear end of the vehicle, and the mounting member is arranged in the vicinity of the external wire pull-out portion.

[0017] According to the third invention, the shackle for the disaster prevention vehicle is positioned near the outside-vehicle pull-out portion of the wire of the winch device, so that the shackle for the disaster prevention vehicle can be effectively used in conjunction with the use of the winch device, contributing to improved workability.

[0018] A fourth invention is the third invention, wherein the vehicle exterior lead-out portion is attached to the mounting base.

[0019] According to the fourth invention, the mounting base, which has a highly strong structure, can be used to fix the outside-vehicle pull-out portion of the winch device's wire and to fix the mounting member of the shackle for the disaster prevention vehicle, thereby efficiently improving the overall strength. [Effects of the Invention]

[0020] The shackle for a disaster prevention vehicle and the disaster prevention vehicle according to the present invention do not generate noise while the vehicle is running, are easy to use, and can suppress damage to each part of the shackle for a disaster prevention vehicle and its surrounding areas.

FIG. 6 is a front view of the shackle 100 for a disaster prevention vehicle according to this embodiment. In this specification, the front of the shackle 100 for a disaster prevention vehicle is the surface arranged so that the insertion direction of the shackle bolt 102 is from the left to the right as shown in FIG. 6. FIG. 7 is a rear view of the shackle 100 for a disaster prevention vehicle. FIG. 8 is a left side view of the shackle 100 for a disaster prevention vehicle. FIG. 9 is a right side view of the shackle 100 for a disaster prevention vehicle. FIG. 10 is a plan view of the shackle 100 for a disaster prevention vehicle. FIG. 11 is a bottom view of the shackle 100 for a disaster prevention vehicle. The structure of the shackle 100 for a disaster prevention vehicle will be described in detail based on FIGS. 4 to 11.

[0030] The shackle 100 for a disaster prevention vehicle is attached to a mounting member 11 provided on the disaster prevention vehicle 1. As shown in FIGS. 4 to 11, the shackle 100 for a disaster prevention vehicle includes a metal shackle body 101, a metal shackle bolt 102, a metal nut portion 105, and an anti-vibration spacer 104. As shown in FIG. 4, the shackle body 101 has a curved portion 101b formed in a U-shape, a pair of shaft portions 101c, 101c connected to the curved portion 101b, and body holes 101a formed at each end of the pair of shaft portions 101c, 101c. The shackle body 101 of this embodiment is what is called a bow type, with the central portion bulging out in an arc-like shape more than both end portions. With the mounting member 11 positioned between both ends (the pair of shanks 101c, 101c) of the shackle body 101, the shackle bolt 102 is inserted through the mounting hole 11a of the mounting member 11 and the pair of body holes 101a, 101a, thereby setting the open portion O (see FIG. 14) formed between the pair of shanks 101c, 101c to the closed state C. The shackle bolt 102 has a male threaded portion 102b formed on one end and a head portion 102a formed on the other end. A slip-out prevention mounting hole 102c is provided at the tip of the male threaded portion 102b.

[0031] The anti-vibration spacer 104 is made of a flexible material. For example, the anti-vibration spacer 104 is made of nitrile rubber (NBR). However, the anti-vibration spacer 104 may be made of other flexible materials. For example, it may be made of natural rubber (NR), chloroprene rubber (CR), butyl rubber (IIR), ethylene propylene rubber (EPDM), etc. As shown in FIG. 5, the anti-vibration spacer 104 is ring-shaped and has a spacer hole 104a formed in its center. As shown in FIG. 4, the anti-vibration spacer 104 is fitted onto the shackle bolt 102 using the spacer hole 104a. The anti-vibration spacer 104 is disposed between the pair of shaft portions 101c, 101c and the mounting member 11. A pair of anti-vibration spacers 104 are provided along one side surface and the other side surface of the mounting member 11.

[0032] The nut portion 105 is threadedly engaged with the male thread portion 102b of the shackle bolt 102 in the disengaged state C. When the nut portion 105 is threadedly engaged with the male thread portion 102b, a retaining pin 103 is attached to the retaining mounting hole 102c, thereby preventing the nut portion 105 from falling off the shackle bolt 102. When the nut portion 105 is tightened in the disengaged state C, the nut portion 105 is configured to prevent the shackle body 101 from vibrating relative to the mounting member 11. Specifically, when the nut portion 105 is tightened, the anti-vibration spacers 104 are sandwiched between the mounting member 11 and both ends of the shackle body 101. When an attempt is made to rotate the shackle body 101 around the axis of the shackle bolt 102, large frictional forces are generated between the mounting member 11 and the anti-vibration spacers 104, and between both ends of the shackle body 101 and the anti-vibration spacers 104.

[0033] The shackle 100 for a disaster prevention vehicle having the above configuration is attached to a front attachment member 111 at the front end of the vehicle, as shown in Fig. 2. In this embodiment, the shackle 100 for a disaster prevention vehicle at the front end of the vehicle is attached so as to be exposed to the outside when viewed from the side of the vehicle, as shown in Fig. 1. In addition, the shackle 100 for a disaster prevention vehicle is attached to a rear attachment member 112 at the rear end of the vehicle, as shown in Figs. 3 and 4. In this embodiment, the shackle 100 for a disaster prevention vehicle at the rear end of the vehicle is attached so as to be hidden inside the vehicle when viewed from the side of the vehicle, as shown in Fig. 1.

[0034] As shown in Figures 3 and 4, the shackle 100 for a disaster prevention vehicle at the rear end of the vehicle is accommodated in an accommodating recess 71 of the rear bumper 7. The accommodating recess 71 is open to the rear of the vehicle and is rectangular when viewed from the rear of the vehicle. A bottom hole 71a is provided in the bottom wall of the accommodating recess 71. The rear mounting member 112 is arranged to pass through the bottom hole 71a in the fore-and-aft direction of the vehicle.

[0035] Fig. 12 is a side view of essential parts showing the attachment state of the front attachment member 111 and the shackle 100 for the disaster prevention vehicle at the front end of the disaster prevention vehicle 1. Fig. 13 is a side view of essential parts showing the attachment state of the rear attachment member 112 and the shackle 100 for the disaster prevention vehicle at the rear end of the disaster prevention vehicle 1. Of the attachment members 11 of this embodiment, the front attachment member 111 used at the front end of the vehicle is formed in a band-like shape as shown in Fig. 12. The front attachment member 111 is disposed near the front external lead-out portion 82. The front attachment member 111 has one attachment hole 11a and three fastening holes 11b lined up along the longitudinal direction.

[0036] The mounting holes 11a of the front mounting member 111 are provided at the front end. The fastening holes 11b are provided at equal intervals from the center to the rear end. The front mounting member 111 is attached to the mounting base 91. Specifically, the front mounting member 111 is attached to the front mounting base 91 with fastening members 12 that are inserted through the fastening holes 11b. The front mounting member 111 is positioned so that the mounting holes 11a on the front side of the vehicle and the surrounding area are exposed to the outside of the vehicle, and the fastening holes 11b on the rear side of the vehicle are located inside the vehicle.

[0037] In this embodiment, the front mounting base 91 extends in the vehicle width direction. The front mounting base 91 is used to secure the front externally drawn portion 82 of the winch device 8. The front mounting base 91 is formed sturdy because it is subjected to a large load by the front wire 84 drawn out from the front externally drawn portion 82. The rear end of the front mounting base 91 is fixed to the front end of the chassis frame 2 by welding or the like. The chassis frame 2 is formed sturdy and has the strength to support the cab 4 and the storage shed 5. Therefore, the front mounting member 111 is configured to stably support the shackle 100 for a disaster prevention vehicle even if a large tensile force is applied to the shackle body 101 of the shackle 100 for a disaster prevention vehicle.

[0038] Of the mounting members 11 of this embodiment, the rear mounting member 112 used at the rear end of the vehicle is formed in a strip shape, as shown in FIG. 13 . The rear mounting member 112 is disposed near the rear vehicle-exterior drawing portion 83. The length of the rear mounting member 112 is shorter than the length of the front mounting member 111. The rear mounting member 112 has one mounting hole 11a and two fastening holes 11b lined up along the longitudinal direction. The mounting hole 11a of the rear mounting member 112 is provided at the rear end. The fastening holes 11b are provided at equal intervals from the center to the front end. The rear mounting member 112 is attached to the mounting base 92. Specifically, the rear mounting member 112 is attached to the rear mounting base 92 by fastening members 12 inserted through the fastening holes 11b. The rear mounting member 112 is arranged so that the mounting hole 11a on the rear side of the vehicle and the area nearby are exposed to the outside of the vehicle, and the fastening hole 11b on the front side of the vehicle is located inside the vehicle.

[0039] In this embodiment, the rear mounting base 92 is formed in the shape of a rectangular plate with the vertical direction as the longitudinal direction. The upper end of the rear mounting base 92 is attached to the subframe 3 by welding. The lower end of the rear mounting base 92 extends to a height position of the chassis frame 2. A hole (not shown) is formed in the lower end of the rear mounting base 92. The rear mounting member 112 is attached using the fastening member 12 by utilizing this hole.

[0040] Fig. 14 is a perspective view for explaining the force acting on the shackle body 101 of the shackle 100 for a disaster prevention vehicle according to this embodiment. In the shackle 100 for a disaster prevention vehicle in the disconnected state C, as shown in Fig. 14, a tightening force F1 acts on both ends of the shackle body 101 in a direction that contracts the open portion O by tightening the nut portion 105. The tightening force F1 also acts on the anti-vibration spacers 104 via both ends of the shackle body 101. In response to this tightening force F1, both ends of the shackle body 101 receive a reaction force F2 from the anti-vibration spacers 104.

[0041] Here, because the anti-vibration spacer 104 is formed from a flexible material, even if both ends of the shackle body 101 actually bend in a direction that shortens the open portion O or if the orientation of both ends of the shackle body 101 changes relative to the axial direction of the shackle bolt 102, the anti-vibration spacer 104 can flexibly deform. Therefore, even if both ends of the shackle body 101 bend or the orientation of both ends of the shackle body 101 changes, a sudden increase in the reaction force F2 can be suppressed. This also suppresses the force moment generated at both ends of the shackle body 101. As a result, when a tensile force F3 is generated from a rope or the like connected to the shackle body 101, stress generated in the inner region A and outer region B of the arc-shaped central portion of the shackle body 101 can be suppressed.

[0042] As described above, the shackle 100 for an emergency vehicle according to this embodiment is attached to the attachment member 11 provided on the emergency vehicle 1. The shackle 100 for a disaster prevention vehicle comprises: a shackle body 101 having a curved portion 101b formed in a U-shape, a pair of shanks 101c, 101c connected to the curved portion 101b, and a body hole portion 101a formed at each end of the pair of shanks 101c, 101c; a shackle bolt 102 that is inserted into the mounting hole portion 11a of the mounting member 11 and the pair of body holes 101a, 101a when the mounting member 11 is positioned between the pair of shanks 101c, 101c, thereby bringing the opening O formed between the pair of shanks 101c, 101c into a blocked state C; a nut portion 105 that is threaded onto the male thread portion 102b of the shackle bolt 102 in the blocked state C; and an anti-vibration spacer 104 that is fitted onto the shackle bolt 102 and is positioned between the pair of shanks 101c, 101c and the mounting member 11. The anti-vibration spacer 104 is formed from a flexible member, and is configured to prevent the shackle body 101 from vibrating relative to the mounting member 11 by tightening the nut portion 105 in the disconnected state C.

[0043] According to the above configuration, the anti-vibration spacer 104 is sandwiched between the mounting member 11 and both ends of the shackle body 101. Furthermore, when the shackle body 101 is attempted to rotate around the axis of the shackle bolt 102, a large frictional force can be generated between the mounting member 11 and the anti-vibration spacer 104, and between both ends of the shackle body 101 (the pair of shafts 101c, 101c) and the anti-vibration spacer 104. This prevents the shackle body 101 from being violently shaken even if the body of the disaster prevention vehicle 1 shakes while it is traveling. This prevents the shackle body 101 from colliding with the periphery of the mounting member 11 while the vehicle is traveling, thereby preventing noise generation and damage to the periphery of the mounting member 11.

[0044] Furthermore, large frictional forces can be generated between the mounting member 11 and the anti-vibration spacers 104, and between both ends of the shackle body 101 and the anti-vibration spacers 104, so that when the shackle body 101 is stopped at a desired rotation angle relative to the mounting member 11, that position can be self-maintained. This makes it easy to attach a rope to the shackle body 101 or to attach a hook to it, improving workability.

[0045] Furthermore, because flexible anti-vibration spacers 104 are disposed between both ends of the shackle body 101 and the mounting member 11, when the shackle body 101 is pulled by the rope connected to the shackle body 101, both ends of the shackle body 101 can flex flexibly in the axial direction of the shackle bolt 102. Furthermore, even if the orientation of both ends of the shackle body 101 changes relative to the axial direction of the shackle bolt 102, the anti-vibration spacers 104 can flexibly deform. This makes it possible to suppress the force moment generated at both ends of the shackle body 101. This makes it possible to suppress the generation of stress due to the force moment at the arc-shaped central portion of the shackle body 101. As a result, damage to the shackle body 101 can be suppressed.

[0046] In the above embodiment, the disaster prevention vehicle 1 includes a chassis frame 2 extending in the longitudinal direction of the vehicle, and a mounting base 9 fixed to an end of the chassis frame 2 in the longitudinal direction of the vehicle. The mounting member 11 has a mounting hole 11a and a fastening hole 11b and is formed in a strip shape. The mounting hole 11a is provided at one end of the mounting member 11. The mounting member 11 is positioned so that the mounting hole 11a and its neighboring portion are exposed to the outside of the vehicle and the fastening hole 11b is located inside the vehicle, and is attached to the mounting base 9 by a fastening member 12 inserted through the fastening hole 11b.

[0047] According to the above configuration, the shackle 100 for the disaster prevention vehicle can be fixed using the high-strength chassis frame 2. In addition, the fastening portion of the mounting member 11 to the mounting base 9 is hidden inside the vehicle, which improves the appearance of the vehicle.

[0048] In the above embodiment, the disaster prevention vehicle 1 is equipped with a winch device 8 having a front external pull-out portion 82 at the front end of the vehicle and a rear external pull-out portion 83 at the rear end of the vehicle. The mounting members 11 are disposed near the front external pull-out portion 82 and the rear external pull-out portion 83, respectively.

[0049] According to the above configuration, the shackle 100 for the disaster prevention vehicle is positioned near the front external pull-out portion 82 and the rear external pull-out portion 83 of the winch device 8, so that the shackle 100 for the disaster prevention vehicle can be effectively used in accordance with the use of the winch device 8, contributing to improved workability.

[0050] In the above embodiment, the front externally extending portion 82 is attached to the front mounting base 91. According to this configuration, the front mounting base 91, which has a highly strong structure, can be used to fix both the front externally extending portion 82 and the front mounting member 111 of the disaster prevention vehicle shackle 100, thereby efficiently improving the overall strength.

[0051] FIG. 15 is a side view showing an anti-vibration spacer 204 of a modified shackle for a disaster prevention vehicle 200. FIG. 16 is a schematic diagram for explaining the attachment of the modified shackle for a disaster prevention vehicle 200 to the attachment member 11. The anti-vibration spacer 204 of the shackle for a disaster prevention vehicle 200 has a space hole 204a and an annular protrusion 204b formed around the space hole 204a. The presence or absence of the annular protrusion 204b is a major difference from the anti-vibration spacer 104 described above. Furthermore, the anti-vibration spacer 204 is formed so that the thickness of the portion radially outward of the annular protrusion 204b is thicker than that of the anti-vibration spacer 104. The material of the anti-vibration spacer 204 is the same as that of the anti-vibration spacer 104. The shackle for a disaster prevention vehicle 200 has the same structure as the shackle for a disaster prevention vehicle 100 except for the anti-vibration spacer 204.

[0052] The shackle 200 for a disaster prevention vehicle has a thick anti-vibration spacer 204 press-fitted between the pair of shafts 101c, 101c of the shackle body 101 and the mounting member 11, thereby generating a large frictional force between the both ends of the shackle body 101 (the pair of shafts 101c, 101c) and the anti-vibration spacer 204. As shown in Figure 16, the anti-vibration spacer 204 is attached to the position of the body hole 101a of the shackle body 101 (arrow A in Figure 16). At this time, the annular protrusion 204b of the anti-vibration spacer 204 is inserted inside the body hole 101a of the shackle body 101, that is, fitted into the open portion O of the body hole 101a of the shackle body 101.

[0053] In this way, the two anti-vibration spacers 204, 204 are attached to the open portion O side of the shaft portion 101c of the shackle body 101. In this state, each anti-vibration spacer 204 protrudes toward the center of the open portion O by an amount equal to the press-fitting dimension difference df from the normal attachment position of the attachment member 11. The shackle body 101 with the two anti-vibration spacers 204, 204 attached is attached by press-fitting each anti-vibration spacer 204 between the shaft portion 101c of the shackle body 101 and the attachment member 11 (arrow B in Figure 16). During this press-fitting, the annular protrusion 204b of the anti-vibration spacer 204 prevents the relative position of the body hole 101a of the shackle body 101 and the anti-vibration spacer 204 from shifting. That is, the two anti-vibration spacers 204, 204 can be press-fitted while suppressing misalignment up to the position where the shackle bolt 102 is inserted into the mounting hole 11a of the mounting member 11 (arrow C in FIG. 16). This makes it easier to insert the shackle bolt 102.

[0054] The embodiments disclosed herein are illustrative in all respects and are not intended to be limiting. The technical scope of the present invention is not to be interpreted solely by the above-described embodiments, but is defined by the claims. The technical scope of the present invention also includes all modifications within the scope and meaning equivalent to the claims.

[0055] For example, in the above embodiment, the shackle 100 for a disaster prevention vehicle is attached to the front attachment member 111 at the front end of the disaster prevention vehicle 1 and to the rear attachment member 112 at the rear end of the vehicle. The present invention is not limited to this, and the shackle for a disaster prevention vehicle may be provided at only one of the front end and rear end of the disaster prevention vehicle. Furthermore, the shackle for a disaster prevention vehicle may not be provided at either the front end or rear end of the disaster prevention vehicle, but may be attached to another location on the disaster prevention vehicle.

[0056] In the above embodiment, the front mounting member 111 of the shackle 100 for a disaster prevention vehicle is fixed to the front mounting base 91. The front external drawable portion 82 is also fixed to this front mounting base 91. However, the present invention is not limited to this, and the mounting member of the shackle for a disaster prevention vehicle may be attached to the disaster prevention vehicle in any manner.
