DETAILED DESCRIPTION OF THE INVENTION

[0018] In each drawing, the dimensions of the components may be enlarged or reduced relative to the actual dimensions, for example, to facilitate understanding, and the dimensional ratios between the drawings may not be consistent. Note that in each drawing, for example, to facilitate understanding, some of the components may be omitted.

[0019] Terms including ordinal numbers such as "first" and "second" are used to describe various components, but these terms are used only to distinguish one component from another, and the components are not particularly limited by these terms. The number of components including ordinal numbers is not particularly limited, and may be, for example, one. Furthermore, the ordinal numbers used in the following specification and drawings may differ from the ordinal numbers described in the claims.

[0020] An embodiment of a container vehicle will be described below with reference to Figures 1 to 16. Note that the following embodiment is provided as an example to facilitate understanding of the configuration of the container vehicle, and is not intended to limit the configuration of the container vehicle.

[0021] 1 and 2, a container vehicle 1 may include, for example, a self-propelled towing vehicle 2 and a towed vehicle 10 that is not self-propelled and is towed by the towing vehicle 2. The combined vehicle of the towing vehicle 2 and the towed vehicle 10 that are coupled together is also referred to as a coupled vehicle 1.

[0022] The towing vehicle 2 may, for example, as in this embodiment, include a vehicle body 3 and a cargo handling device 4 connected to the vehicle body 3 and configured to move (load and unload) the container 8. The vehicle body 3 may, for example, as in this embodiment, include a driver's cab 3a arranged at the front, a vehicle body frame 3b arranged at the rear on which the container 8 is placed, and a plurality of wheels 3c.

[0023] In the following description and drawings, the first direction D1 is also referred to as the front-to-rear direction (also referred to as the "first lateral direction") D1, the second direction D2 is also referred to as the left-to-right direction (also referred to as the "second lateral direction") D2, and the third direction D3 is also referred to as the up-down direction D3. In other words, each of the directions D1 to D3 is a direction seen from the perspective of a person (driver) sitting in the driver's seat in the driver's cab 3a of the towing vehicle 2 (container vehicle 1) when the container vehicle 1 is traveling.

[0024] Of the front-to-rear direction D1, the direction of the arrow in the figure is the front direction, and the direction opposite to the arrow direction in the figure is the rear direction. Furthermore, of the left-to-right direction D2, the direction of the arrow in the figure is the left direction, and the direction opposite to the arrow direction in the figure is the right direction. Furthermore, of the up-down direction D3, the direction of the arrow in the figure is the up direction, and the direction opposite to the arrow direction in the figure is the down direction.

[0025] The cargo handling device 4 may include, for example, an arm 4a rotatably connected to the vehicle body 3, and a hook 4b fixed to the tip of the arm 4a, as in this embodiment. As a result, by rotating the arm 4a relative to the vehicle body 3 with the container 8 hooked onto the hook 4b, the container 8 can be transferred between the towing vehicle 2 and the towed vehicle 10, or loaded or unloaded between the towing vehicle 2 and the ground.

[0026] The towing vehicle 2 also includes an engine 5 and a drive switching unit 6 that can switch the destination of the drive power of the engine 5. The drive switching unit 6 can switch between a first state (travelable state, container immobile state) in which the drive power of the engine 5 is transmitted to the wheels 3c, and a second state (container movable state, travel immobile state) in which the drive power of the engine 5 is transmitted to the cargo handling device 4.

[0027] 1 to 3, the towed vehicle 10 includes a vehicle body 11 on which a container 8 is placed, and a towing device 12 that connects the vehicle body 11 to the towing vehicle 2. The towed vehicle 10 may also include a first stop device 20 and a second stop device 13 that stop the container 8 placed on the vehicle body 11, for example, as in this embodiment.

[0028] The vehicle body 11 may, for example, as in this embodiment, include a vehicle body frame 14 on which the container 8 is placed, and a plurality of wheels 15 spaced apart in the fore-and-aft direction D1. This allows the towed vehicle 10 to support its own weight with the wheels 15. Therefore, the towed vehicle 10 is generally a vehicle called a full trailer.

[0029] The towed device 12 may be connected to the front end of the vehicle body 11, as in this embodiment, and thereby be disposed at the front end of the towed vehicle 10. The towed device 12 may also be provided at its front end with a coupling portion 12a that is coupled to the towing vehicle 2, as in this embodiment.

[0030] 1, the towed device 12 may be configured to assume an unfolded position extending in the front-to-rear direction D1, so that the coupling part 12a moves forward from the vehicle body 11 and is positioned at a coupling position where it is coupled to the towing vehicle 2. As a result, the coupling part 12a is coupled to the towing vehicle 2, and the container vehicle 1 can travel with the towed vehicle 10 connected to the towing vehicle 2.

[0031] 2, the towed device 12 may be configured to bend into a stored position, so that the coupling portion 12a is positioned at a non-coupled position that is rearward of the coupled position. This allows the rear end of the towing vehicle 2 to approach the front end of the towed vehicle 10, making it possible to transfer the container 8 between the towing vehicle 2 and the towed vehicle 10.

[0032] 3, the second abutting device 13 may include a third abutting body 13a that abuts and stops the container 8 placed on the vehicle body 11, as in this embodiment. The third abutting body 13a may be arranged rearward of the container 8, as in this embodiment, and may be fixed immovably to the vehicle body 11 so as to abut and stop the container 8 in the fore-and-aft direction D1 (specifically, from the rear). The container 8 includes rollers 8a (hereinafter also referred to as "container rollers") that are guided by the vehicle body 11.

[0033] 4 and 5, the body frame 14 may include, for example, front and rear frames 14a extending in the front-rear direction D1 and left and right frames 14b extending in the left-right direction D2, as in this embodiment. Also, the container 8 may include, for example, a container frame 8b (see FIG. 8) extending in the front-rear direction D1 at its lower end, as in this embodiment.

[0034] The body frame 14 has mounting surfaces 14c, 14d on which the containers 8 are placed. For example, as in the present embodiment, the mounting surfaces 14c, 14d may have a first mounting surface 14c on which the container rollers 8a are placed and a second mounting surface 14d on which the container frame 8b is placed. As a result, the first mounting surface 14c is an upward-facing surface that supports the outer peripheral surfaces of the container rollers 8a from below, and the second mounting surface 14d is an upward-facing surface that supports the lower surfaces of the container frames 8b from below.

[0035] The first loading surface 14c also serves as a vehicle body guide surface 14c that guides the outer peripheral surface of the container roller 8a from below. The vehicle body frame 14 has a recess 14e that opens onto the vehicle body guide surface 14c. Although not particularly limited, the first loading surface 14c may be lower than the second loading surface 14d, for example, as in this embodiment.

[0036] 5 to 10, the first abutment device 20 includes abutment bodies 21, 22 that abut and stop the container 8 placed on the placement surfaces 14c, 14d, operation units 23, 24 that are operated to move relative to the vehicle body 11, and an operating unit 25 that connects the operation units 23, 24 and the abutment bodies 21, 22, and interlocks the abutment bodies 21, 22 as the operation units 23, 24 move relative to the vehicle body 11. Although not particularly limited, the operation units 23, 24 may be, for example, handles (e.g., lever handles) having grips, as in the present embodiment.

[0037] The operating unit 25 includes a first shaft portion 26 to which the first abutment body 21 and the first operating unit 23 are fixed, a second shaft portion 27 to which the second abutment body 22 and the second operating unit 24 are fixed, and tubular portions 28, 29 that are fixed to the vehicle body 11 and inserted into the shaft portions 26, 27. As a result, the operating unit 25 connects the operating units 23, 24 and the abutment bodies 21, 22 by the shaft portions 26, 27, i.e., by only mechanical elements, and the tubular portions 28, 29 rotatably support the shaft portions 26, 27.

[0038] Therefore, when the operating units 23, 24 are operated and move relative to the vehicle body 11, the shafts 26, 27 rotate about an axis in the front-to-rear direction D1 relative to the vehicle body 11, and the abutment stop bodies 21, 22 rotate about an axis in the front-to-rear direction D1 between the abutment stop position (the position shown in FIGS. 5 to 7) and the non-abutment stop position (the position shown in FIGS. 8 to 10). In this way, the abutment stop bodies 21, 22 move between the abutment stop position and the non-abutment stop position.

[0039] Moreover, the operating section 25 may include, for example, as in this embodiment, a connecting section 30 that connects the first shaft section 26 and the second shaft section 27. For example, as in this embodiment, the connecting section 30 may include a first fixed body 30a fixed to the first shaft section 26, a second fixed body 30b fixed to the second shaft section 27, and a long connecting body 30c rotatably connected to each of the first fixed body 30a and the second fixed body 30b.

[0040] As a result, since the connecting portion 30 connects the first shaft portion 26 and the second shaft portion 27, the operating portion 25 connects the first abutment body 21 and the second abutment body 22 only by the connecting portion 30 and the shaft portions 26, 27, that is, by mechanical elements. Therefore, the first abutment body 21 and the second abutment body 22 move in conjunction with each other, so that the positions (abutment position, non-abutment position) of the first abutment body 21 and the second abutment body 22 coincide with each other.

[0041] The number of the abutment bodies 21, 22 of the first abutment device 20 is not particularly limited, and may be, for example, two as in this embodiment, or may be, for example, one, or may be, for example, three or more. The number of operation units 23, 24 of the first abutment device 20 is also not particularly limited, and may be, for example, the same as the number of the abutment bodies 21, 22 as in this embodiment, or may be, for example, fewer than the number of the abutment bodies 21, 22, or may be, for example, more than the number of the abutment bodies 21, 22.

[0042] The first abutment device 20 also includes a position detection unit 31 that detects that the abutment bodies 21, 22 are positioned at the abutment positions. The position detection unit 31 may include, for example, as in this embodiment, a sensor (e.g., a photoelectric sensor, a proximity sensor, a contact sensor, etc.) 31a, a detectable body 31b that is detected by the sensor 31a, a first bracket 31c that fixes the sensor 31a to the vehicle body 11 (specifically, the vehicle body frame 14), and a second bracket 31d that fixes the detectable body 31b to the first shaft portion 26.

[0043] 5 to 7, when the abutment stop bodies 21, 22 are located at the abutment stop positions, portions of the abutment stop bodies 21, 22 are disposed above the placement surfaces 14c, 14d. The abutment stop bodies 21, 22 are provided with a first abutment stop portion 21b (only the first abutment stop portion 21b of the first abutment stop body 21 is shown) that abuts and stops the container 8. As a result, the abutment stop bodies 21, 22 abut and stop the container 8 placed on the placement surfaces 14c, 14d.

[0044] For example, as in this embodiment, the abutment bodies 21, 22 may be arranged forward of the container 8 and, when located at the abutment position, may abut and stop the container 8 in the front-to-rear direction D1 (specifically, from the front). As a result, the first and second abutment bodies 21, 22 of the first abutment device 20 and the third abutment body 13a (see FIG. 3) of the second abutment device 13 sandwich the container 8 in the front-to-rear direction D1. Therefore, it is possible to prevent the container 8 from moving in the front-to-rear direction D1 relative to the vehicle body 11.

[0045] Note that the towed vehicle 10 may be equipped with, for example, a stop device (not shown) that stops the container 8 by stopping it in the left-right direction D2 and the up-down direction D3 in addition to the first stop device 20 and the second stop device 13. This not only prevents the container 8 from moving in the front-back direction D1 relative to the vehicle body 11, but also prevents the container 8 from moving in the left-right direction D2 and the up-down direction D3 relative to the vehicle body 11.

[0046] 8 to 10, when the abutment bodies 21, 22 are located in the non-abutment positions, the abutment bodies 21, 22 are spaced apart from the container 8 placed on the placement surfaces 14c, 14d. When the abutment bodies 21, 22 are located in the non-abutment positions, the entire first abutment device 20 is disposed below the placement surfaces 14c, 14d.

[0047] This makes it possible to prevent the container 8 from colliding with the first abutting device 20 when loading or unloading the container 8 onto or from the placement surfaces 14c, 14d. Specifically, because the abutting bodies 21, 22 abut and stop the front end of the container 8, when the rear end of the towing vehicle 2 is brought close to the front end of the towed vehicle 10 and the container 8 is transferred between the towing vehicle 2 and the towed vehicle 10 (see FIG. 2), the abutting bodies 21, 22 can be positioned in the non-abutting position to prevent the container 8 from colliding with the first abutting device 20.

[0048] When the abutment stop bodies 21, 22 are located at the non-abutment stop positions, they are accommodated in the recessed portion 14e of the body frame 14 and are arranged at positions where they can guide the container rollers 8a. The abutment stop bodies 21, 22 are provided with flat abutment stop guide surfaces 21a, 22a that guide the container rollers 8a when located at the non-abutment stop positions.

[0049] As a result, when the container roller 8a passes through the recess 14e, the abutment bodies 21, 22 positioned in the non-abutment position guide the container roller 8a with the flat abutment guide surfaces 21a, 22a. Therefore, the container roller 8a passing through the recess 14e can be smoothly guided by the abutment guide surfaces 21a, 22a of the abutment bodies 21, 22.

[0050] The difference in position in the up-down direction D3 between the abutment guide surfaces 21a, 22a and the vehicle body guide surface 14c around the recess 14e (e.g., the height of the step) is not particularly limited. For example, the difference in position in the up-down direction D3 may be 26% or less of the diameter of the container roller 8a. Also, for example, the difference in position in the up-down direction D3 may be 50% or less of the maximum inner width dimension of the recess 14e in the front-rear direction D1. Also, for example, the difference in position in the up-down direction D3 may be 58 mm or less.

[0051] The abutment bodies 21, 22 are detachable from the vehicle body 11. For example, the abutment bodies 21, 22 may be configured to be detachable from the shaft portions 26, 27, or the abutment bodies 21, 22 and the shaft portions 26, 27 may be configured to be detachable from the cylindrical portions 28, 29.

[0052] As a result, as shown in Figures 6 and 11, the abutment bodies 21, 22 (only the first abutment body 21 is shown in Figures 6 and 11, and is shown by a two-dot chain line in Figure 11) can be attached to the car body 11 in a first orientation. The abutment body 21 is provided with a first abutment portion 21b that abuts and stops the container 8 when attached in the first orientation. The position of the first abutment portion 21b with respect to the car body 11 when the abutment body 21 is attached in the first orientation (the position shown in Figure 6, the position shown by a two-dot chain line in Figure 11) is referred to as a first abutment position.

[0053] 11, the abutment stop bodies 21, 22 (only the first abutment stop body 21 is shown in FIG. 11, and is shown by a solid line) can be attached to the car body 11 in a second orientation. The abutment stop body 21 is provided with a second abutment stop portion 21c that abuts and stops the container 8 when attached in the second orientation. The position of the second abutment stop portion 21c with respect to the car body 11 when the abutment stop body 21 is attached in the second orientation (the position shown by the solid line in FIG. 11) is referred to as a second abutment stop position.

[0054] At this time, the first abutment position of the first abutment portion 21b (the position shown by the two-dot chain line in FIG. 11) is different from the second abutment position of the second abutment portion 21c (the position shown by the solid line in FIG. 11). As a result, the attachment direction of the abutment bodies 21, 22 relative to the car body 11 can be changed, thereby making it possible to abut and stop containers 8 of different sizes.

[0055] For example, as in this embodiment, the first abutment position of the first abutment portion 21b may be forward of the second abutment position of the second abutment portion 21c. As a result, the length in the front-rear direction D1 of the container 8 against which the abutment body 21 attached in the first orientation can abut and be stopped is longer than the length in the front-rear direction D1 of the container 8 against which the abutment body 21 attached in the second orientation can abut and be stopped.

[0056] 12 and 13, the first abutment device 20 may include a holding portion 32 that holds the abutment bodies 21, 22 at the abutment position and the non-abutment position. As shown in FIG. 12 and FIG. 13, the holding portion 32 includes an insertion portion 33 that is inserted into the second shaft portion 27 and the second cylindrical portion 29.

[0057] The second cylindrical portion 29 has cylindrical openings 29a and 29b that are inserted into the insertion portion 33. The cylindrical openings 29a and 29b may have, for example, a first cylindrical opening 29a and a second cylindrical opening 29b that faces the first cylindrical opening 29a in the radial direction of the second cylindrical portion 29, as in this embodiment.

[0058] The second shaft portion 27 includes a first shaft opening 27a that communicates with the cylinder openings 29a, 29b and is inserted into the insertion portion 33 when the abutment bodies 21, 22 (only the second abutment body 22 is shown in FIGS. 12 and 13) are positioned at the abutment position, and a second shaft opening 27b that communicates with the cylinder openings 29a, 29b and is inserted into the insertion portion 33 when the abutment bodies 21, 22 are positioned at the non-abutment position. The first shaft opening 27a and the second shaft opening 27b may be formed to penetrate the second shaft portion 27 in the radial direction, for example, as in this embodiment.

[0059] 12, when the abutment bodies 21, 22 (only the second abutment body 22 is shown in FIG. 12) are located at the abutment position, the cylindrical openings 29a, 29b communicate with the first shaft opening 27a, and the insertion portion 33 is inserted into the cylindrical openings 29a, 29b and the first shaft opening 27a. This restricts rotation of the second shaft portion 27 relative to the second cylindrical portion 29. Furthermore, the connecting portion 30 (see FIGS. 5 and 8) also restricts rotation of the first shaft portion 26 relative to the first cylindrical portion 28, so the abutment bodies 21, 22 can be held at the abutment position.

[0060] On the other hand, as shown in Fig. 13, when the abutment bodies 21, 22 (only the second abutment body 22 is shown in Fig. 13) are located in the non-abutment position, the cylindrical openings 29a, 29b communicate with the second shaft opening 27b, and the insertion portion 33 is inserted into the cylindrical openings 29a, 29b and the second shaft opening 27b. This restricts rotation of the second shaft portion 27 relative to the second cylindrical portion 29. Furthermore, the connecting portion 30 (see Figs. 5 and 8) also restricts rotation of the first shaft portion 26 relative to the first cylindrical portion 28, so the abutment bodies 21, 22 can be held in the non-abutment position.

[0061] 12 to 14, the insertion portion 33 includes an insertion body portion 33a that is inserted across the second shaft portion 27 and the second tubular portion 29, and retaining portions 33b and 33c that are connected to the ends of the insertion body portion 33a and prevent it from coming off the second tubular portion 29. Note that the insertion portion 33 may be connected to the body frame 14 by, for example, a chain, a wire, or the like (not shown).

[0062] 12 and 13, when the first retaining portion 33b is positioned at the retaining position (the position indicated by the two-dot chain line in FIG. 14), the first retaining portion 33b prevents the second tubular portion 29 from coming off.

[0063] For example, as in this embodiment, the maximum outer width of the retaining portions 33b, 33c (the maximum outer width of the first retaining portion 33b when it is in the retaining position) may be larger than the maximum inner width of the cylindrical openings 29a, 29b. This allows the retaining portions 33b, 33c to abut against the outer peripheral surface of the second cylindrical portion 29.

[0064] 15, when the first retaining portion 33b is positioned at the insertion / removal position (the position indicated by the solid line in FIG. 14), the first retaining portion 33b enables insertion and removal into the second tubular portion 29 and the second shaft portion 27. In this way, by changing the position of the first retaining portion 33b, it is possible to switch between a state in which removal from the second tubular portion 29 is prevented and a state in which insertion and removal into the second tubular portion 29 and the second shaft portion 27 are enabled.

[0065] The shape of the cylindrical openings 29a, 29b is not particularly limited as long as it is configured to allow the insertion portion 33 to abut and be stopped in the circumferential direction of the second cylindrical portion 29. Although not particularly limited, the cylindrical openings 29a, 29b may be, for example, circular or polygonal openings, or may be, for example, groove-like openings that extend in the front-rear direction (axial direction of the second cylindrical portion 29) D1 and are partially open.

[0066] Furthermore, for example, like the second axial portion 27 and the second cylindrical portion 29, the first axial portion 26 and the first cylindrical portion 28 may also have openings (first and second axial openings, cylindrical openings) into which the insertion portion 33 is inserted. Furthermore, the openings (first and second axial openings, cylindrical openings) into which the insertion portion 33 is inserted may be provided, for example, only in the second axial portion 27 and the second cylindrical portion 29, or may be provided, for example, only in the first axial portion 26 and the first cylindrical portion 28.

[0067] 16, the container vehicle 1 may include, for example, an input unit 41 to which information is input, a control unit 42 that controls the units 6 and 43, and an output unit 43 that outputs information. The container vehicle 1 may also include, for example, a drive state detection unit (not shown) that detects the state switched by the drive switching unit 6.

[0068] The input unit 41 is not particularly limited, and may be, for example, a switch (push button switch, select switch, etc.), a touch panel, a steering wheel, pedals, etc. Furthermore, the input unit 41 may be provided only in the towing vehicle 2, for example, or only in the towed vehicle 10, or may be provided in both the towing vehicle 2 and the towed vehicle 10, for example.

[0069] The control unit 42 is not particularly limited, and may be configured with at least one of an electrical circuit (electrical hardware circuit, electrical software circuit), a hydraulic circuit, and a compressed air circuit. The control unit 42 may be provided only in the towing vehicle 2, or only in the towed vehicle 10, or both in the towing vehicle 2 and the towed vehicle 10.

[0070] For example, the drive switching unit 6 may be configured such that, by operating a switch while the clutch pedal in the driver's cab 3a (see FIGS. 1 and 2) is depressed, the drive switching unit 6 changes the connection destination of the clutch and switches between the first state and the second state. For example, in the first state (a state in which the vehicle can travel and the container cannot move), the drive of the engine 5 is transmitted to the wheels 3c, and in the second state (a state in which the container can move and the vehicle cannot travel), the drive of the engine 5 is transmitted to a hydraulic device that operates the cargo handling device 4.

[0071] The output unit 43 is not particularly limited, and may, for example, be equipped with a display unit (e.g., a monitor or indicator light) that displays information, or may, for example, be equipped with a sound output unit (e.g., a buzzer or speaker) that outputs information. The output unit 43 may, for example, be equipped only in the towing vehicle 2, or, for example, only in the towed vehicle 10, or, for example, in both the towing vehicle 2 and the towed vehicle 10.

[0072] When the position detection unit 31 detects the abutment bodies 21, 22 located at the abutment stop positions and the drive switching unit 6 is switched to the second state (container movable state, traveling disabled state), the output unit 43 outputs an alarm (for example, an alarm sound or alarm display). This allows the user to recognize that the abutment bodies 21, 22 are located at the abutment stop positions while the cargo handling device 4 is operable.

[0073] Therefore, for example, when the abutment stop bodies 21, 22 are located at the abutment stop positions, it is possible to prevent the cargo handling device 4 from being operated. As a result, it is possible to prevent the cargo handling device 4 from being operated erroneously.

[0074] Furthermore, when the position detection unit 31 does not detect the abutment bodies 21, 22 located at the abutment stop positions and the drive switching unit 6 is switched to the first state (travelable state, container immobilization state), the output unit 43 outputs an alarm (for example, an alarm sound or alarm display). This allows the user to recognize that the container vehicle 1 is in a travelable state and the abutment bodies 21, 22 are not located at the abutment stop positions.

[0075] Therefore, for example, when the abutment stop bodies 21, 22 are not positioned in the abutment stop position, it is possible to prevent the container vehicle 1 from traveling. As a result, it is possible to prevent the container vehicle 1 from traveling erroneously. In this way, it is possible to prevent erroneous operation.

[0076] As described above, the container vehicle 1, as in this embodiment, a vehicle body 11 on which a container 8 can be loaded; abutment bodies 21, 22 that are movable by rotating about an axis of the first direction D1 between an abutment position where the container 8 placed on the vehicle body 11 is abutted and stopped in a first direction (in this embodiment, the front-rear direction) D1 and a non-abutment position where the container 8 is separated from the vehicle body 11; and a holding portion 32 that holds the abutment bodies 21 and 22 at the abutment position. This configuration is preferable.

[0077] According to this configuration, the abutment stop bodies 21, 22 rotate about an axis in the first direction D1, and thereby the abutment stop bodies 21, 22 can move between an abutment stop position where they abut and stop the container 8 placed on the vehicle body 11 in the first direction D1, and a non-abutment stop position where they are separated from the container 8 placed on the vehicle body 11. Then, the holding portion 32 holds the abutment stop bodies 21, 22 at the abutment stop position, so the abutment stop bodies 21, 22 can be held at the abutment stop position.

[0078] In addition, in the container vehicle 1, as in this embodiment, The abutment bodies 21, 22 include a first abutment body 21 and a second abutment body 22, The container vehicle 1 includes an operating unit 25 that connects the first abutment body 21 and the second abutment body 22 so that the first abutment body 21 and the second abutment body 22 are interlocked. This configuration is preferable.

[0079] According to this configuration, the operating portion 25 connects the first abutment body 21 and the second abutment body 22, so that the first abutment body 21 and the second abutment body 22 move in conjunction with each other. This allows the positions (abutment position, non-abutment position) of the first abutment body 21 and the second abutment body 22 to coincide with each other.

[0080] In addition, the container vehicle 1, as in this embodiment, Shafts 26 and 27 to which the abutment bodies 21 and 22 are fixed and which rotate to rotate the abutment bodies 21 and 22 between the abutment position and the non-abutment position; and cylindrical portions 28 and 29 fixed to the vehicle body 11 and inserted onto the shaft portions 26 and 27. The holding portion 32 includes an insertion portion 33 that is inserted across the shaft portion 27 and the cylindrical portion 29, The cylindrical portion 29 has cylindrical openings 29a and 29b into which the insertion portion 33 is inserted. The shaft portion 27 is a first shaft opening 27a that communicates with the cylinder openings 29a and 29b and is inserted into the insertion portion 33 when the abutment bodies 21 and 22 are located at the abutment positions; and a second shaft opening 27b that communicates with the cylinder openings 29a and 29b and is inserted into the insertion portion 33 when the abutting bodies 21 and 22 are located at the non-abutting positions. This configuration is preferred.

[0081] According to this configuration, the abutment bodies 21, 22 are fixed to the shafts 26, 27, and therefore the abutment bodies 21, 22 rotate between the abutment position and the non-abutment position when the shafts 26, 27 rotate, thereby moving the abutment bodies 21, 22 between the abutment position and the non-abutment position.

[0082] When the abutment bodies 21, 22 are located at the abutment stop positions, the cylinder openings 29a, 29b communicate with the first shaft opening 27a, and the insertion portion 33 is inserted into the cylinder openings 29a, 29b and the first shaft opening 27a. This restricts the rotation of the shaft portions 26, 27 relative to the cylinder portions 28, 29, and therefore the abutment bodies 21, 22 can be held at the abutment stop positions.

[0083] On the other hand, when the abutment bodies 21, 22 are located at the non-abutment position, the cylinder openings 29a, 29b communicate with the second shaft opening 27b, and the insertion portion 33 is inserted into the cylinder openings 29a, 29b and the second shaft opening 27b. This restricts the rotation of the shaft portions 26, 27 relative to the cylinder portions 28, 29, and therefore the abutment bodies 21, 22 can be held at the non-abutment position.

[0084] In addition, in the container vehicle 1, as in this embodiment, The insertion portion 33 is an insertion body portion 33a that is inserted across the shaft portion 27 and the cylindrical portion 29; a retaining portion 33b connected to an end of the insertion body portion 33a and preventing the insertion body portion 33a from coming off the cylindrical portion 29; The retaining portion 33b is movably connected to the insertion body portion 33a so as to be movable between a retaining position that allows the retaining portion 33b to be retained from the tubular portion 29 and an insertion / removal position that allows the retaining portion 33b to be inserted into and removed from the tubular portion 29 and the shaft portion 27. This configuration is preferred.

[0085] According to this configuration, when the retaining portion 33b is positioned in the retaining position, the retaining portion 33b prevents the connector from coming out of the tubular portion 29. On the other hand, when the retaining portion 33b is positioned in the insertion / removal position, the retaining portion 33b allows the connector to be inserted into and removed from the tubular portion 29 and the shaft portion 27. As a result, by changing the position of the retaining portion 33b, it is possible to switch between a state in which the connector is prevented from coming out of the tubular portion 29 and a state in which the connector is inserted into and removed from the tubular portion 29 and the shaft portion 27.

[0086] In addition, the container vehicle 1, as in this embodiment, a position detection unit 31 that detects whether the abutment bodies 21, 22 are positioned at the abutment positions; a drive switching unit (6) that can switch between a first state in which the drive of the engine (5) is transmitted to the wheels (3c) and a second state in which the drive of the engine (5) is transmitted to the cargo handling device (4) that moves the container (8); and an output unit 43 that outputs an alarm when the position detection unit 31 detects the abutment bodies 21, 22 and the drive switching unit 6 is switched to the second state. This configuration is preferable.

[0087] According to this configuration, when the position detection unit 31 detects the abutment bodies 21, 22 and the drive switching unit 6 is switched to the second state, the output unit 43 outputs an alarm. This allows the user to recognize that the abutment bodies 21, 22 are located at the abutment positions while the cargo handling device 4 is in an operable state.

[0088] In addition, the container vehicle 1, as in this embodiment, a position detection unit 31 that detects whether the abutment bodies 21, 22 are positioned at the abutment positions; a drive switching unit (6) that can switch between a first state in which the drive of the engine (5) is transmitted to the wheels (3c) and a second state in which the drive of the engine (5) is transmitted to the cargo handling device (4) that moves the container (8); and an output unit 43 that outputs an alarm when the position detection unit 31 does not detect the abutment bodies 21, 22 and the drive switching unit 6 is switched to the first state. This configuration is preferred.

[0089] According to this configuration, when the position detection unit 31 does not detect the abutment bodies 21, 22 and the drive switching unit 6 is switched to the first state, the output unit 43 outputs an alarm. This allows the driver to recognize that the abutment bodies 21, 22 are not located at the abutment positions while the container vehicle 1 is in a state where it can travel.

[0090] In addition, in the container vehicle 1, as in this embodiment, The vehicle body 11 is a vehicle body guide surface 14c that guides the rollers 8a of the container 8 from below; a recess 14e that opens onto the vehicle body guide surface 14c, When the abutting bodies 21 and 22 are located at the non-abutting position, they are accommodated in the recess 14e and are positioned so as to be able to guide the roller 8a. This configuration is preferred.

[0091] According to this configuration, the car body 11 is provided with a recess 14e that opens to the car body guide surface 14c, and the abutment stop bodies 21, 22 are housed in the recess 14e when located at the non-abutment position. Furthermore, since the abutment stop bodies 21, 22 are disposed at positions that allow them to guide the rollers 8a of the container 8 when located at the non-abutment position, the rollers 8a of the container 8 are guided by the abutment stop bodies 21, 22 when passing through the recess 14e. This allows the rollers 8a to be smoothly guided by the abutment stop bodies 21, 22.

[0092] In addition, in the container vehicle 1, as in this embodiment, The abutment bodies 21, 22 are detachable from the vehicle body 11 so as to be attachable to the vehicle body 11 in a first orientation and a second orientation, The abutment bodies 21 and 22 are a first abutment portion 21b that abuts and stops the container 8 when the container is attached in the first orientation; a second abutment portion 21c that abuts and stops the container 8 when the container is attached in the second orientation, When the abutment bodies 21, 22 are attached in the first orientation, the position of the first abutment portion 21b relative to the vehicle body 11 is different from the position of the second abutment portion 21c relative to the vehicle body 11 when the abutment bodies 21, 22 are attached in the second orientation. This configuration is preferable.

[0093] According to this configuration, when the abutment bodies 21, 22 are attached in the first orientation, the position of the first abutment portion 21b relative to the car body 11 is different from the position of the second abutment portion 21c relative to the car body 11 when the abutment bodies 21, 22 are attached in the second orientation. As a result, by changing the attachment orientation of the abutment bodies 21, 22 relative to the car body 11, containers 8 of different sizes can be abutted and stopped appropriately.

[0094] In addition, in the container vehicle 1, as in this embodiment, The abutment bodies 21, 22 are provided with flat abutment guide surfaces 21a that guide the rollers 8a when positioned at the non-abutment positions. This configuration is preferable.

[0095] According to this configuration, when the abutment stop bodies 21, 22 are located in the non-abutment stop positions, the abutment stop guide surfaces 21a, 22a guide the rollers 8a of the container 8. Moreover, because the abutment stop guide surfaces 21a, 22a are flat, the abutment stop bodies 21, 22 can guide the rollers 8a even more smoothly.

[0096] In addition, the container vehicle 1, as in this embodiment, A towed vehicle (10) having a towing device (12) connecting the towing vehicle (2) and the vehicle body (11), The abutment bodies 21, 22 are provided on the towed vehicle 10. This configuration is preferable.

[0097] According to this configuration, the abutment stop bodies 21, 22 are provided on the towed vehicle 10. As a result, by positioning the abutment stop bodies 21, 22 in the non-abutment stop positions, it is possible to prevent the container 8 from colliding with the abutment stop bodies 21, 22 when loading or unloading the container 8 onto or from the towed vehicle 10.

[0098] In addition, the container vehicle 1, as in this embodiment, operating units 23, 24 that move relative to the vehicle body 11 when operated; and an operating unit 25 that connects the operating units 23, 24 and the abutment bodies 21, 22 and moves the abutment bodies 21, 22 between the abutment position and the non-abutment position in conjunction with the operating units 23, 24. This configuration is preferred.

[0099] According to this configuration, the operating unit 25 connects the operating units 23, 24 and the abutment stop bodies 21, 22. As a result, when the operating units 23, 24 are operated and move relative to the vehicle body 11, the abutment stop bodies 21, 22 move in conjunction with the operating units 23, 24 between the abutment stop position and the non-abutment stop position.

[0100] The container vehicle 1 is not limited to the configuration of the above-described embodiment, nor is it limited to the above-described effects. Furthermore, it goes without saying that various modifications can be made to the container vehicle 1 without departing from the spirit of the present invention. For example, it goes without saying that one or more of the configurations, methods, etc. relating to the various modified examples described below may be arbitrarily selected and adopted in the configurations, methods, etc. relating to the above-described embodiment.

[0101] (A) In the container vehicle 1 according to the above embodiment, for example, as shown in Fig. 17, the first abutting device 20 may be configured to include a guide portion 45 that guides the container roller 8a, and the guide portion 45 may be accommodated in the gap between the recess 14e and the abutting body 21 inside the recess 14e and disposed at a position where it can guide the container roller 8a. And, for example, as shown in Fig. 17, the guide portion 45 may be configured to be detachable from the recess 14e so that it can be attached to the recess 14e at a first position and a second position.

[0102] 17(a), when the abutment body 21 is attached to the vehicle body 11 in a first orientation, the guide portion 45 is attached to the recess 14e at a first position. As a result, when the abutment body 21 is positioned at the non-abutment position, the guide portion 45 is accommodated in the gap between the recess 14e and the abutment body 21 inside the recess 14e.

[0103] 17(b), when the abutment body 21 is attached to the vehicle body 11 in the second orientation, the guide portion 45 is attached to the recess 14e at the second position. As a result, when the abutment body 21 is positioned at the non-abutment position, the guide portion 45 is accommodated in the gap between the recess 14e and the abutment body 21 inside the recess 14e.

[0104] Furthermore, since the guide portion 45 is disposed at a position where it can guide the container rollers 8a, when the container rollers 8a pass through the recessed portion 14e, they are guided by the guide portion 45. As a result, when the container rollers 8a pass through the recessed portion 14e, the container rollers 8a can be smoothly guided by the guide portion 45 and the abutment body 21.

[0105] (B) Furthermore, in the container vehicle 1 according to the above embodiment, the holding portion 32 is configured to include an insertion portion 33 that is inserted across the shaft portion 27 and the cylindrical portion 29. However, the container vehicle 1 is not limited to such a configuration.

[0106] (B-1) For example, the holding portion 32 may be configured to include a pressing portion that is fixed to the tubular portion 29 and that presses and contacts the outer periphery of the shaft portion 27. An example of such a configuration is not particularly limited, but may be, for example, a configuration in which the pressing portion is a male screw member, the thread portion of the male screw member is screwed into a female screw hole provided in the tubular portion 29, and the tip end of the male screw member presses and contacts the outer periphery of the shaft portion 27. This makes it possible to hold the abutment bodies 21, 22 in the abutment position and the non-abutment position.

[0107] (B-2) For example, the holding portion 32 may be configured to have an elastic portion that applies an elastic restoring force to the abutment bodies 21 and 22.

[0108] (B-2-1) As an example of such a configuration, although not particularly limited, the holding section 32 may have the configuration shown in Fig. 18. The container vehicle 1 according to Fig. 18 will be described below.

[0109] As shown in Fig. 18, the holding portion 32 is provided with an elastic portion 46 that applies an elastic restoring force to the abutment bodies 21, 22 (only the first abutment body 21 is shown in Fig. 18) by connecting the operating portion 23 and the vehicle body 11 (specifically, the left and right frames 14b of the vehicle body frame 14). Although not particularly limited, as shown in Fig. 18, for example, the elastic portion 46 may be a helical spring that is constantly elastically deformed by extension when the abutment bodies 21, 22 move from the abutment position to the non-abutment position.

[0110] 18(a), when the abutment body 21 is located at the abutment position, the elastic portion 46 is elastically deformed to expand, and therefore generates an elastic restoring force to contract. Therefore, the elastic portion 46 applies an elastic restoring force to the abutment body 21 from the non-abutment position to the abutment position (counterclockwise in FIG. 18) via the operating portion 23 and the shaft portion 26. This allows the abutment bodies 21, 22 to be held at the abutment positions.

[0111] On the other hand, as shown in Figure 18(b), when the abutment body 21 is located in the non-abutment position, the elastic portion 46 is elastically deformed by extension, and therefore generates an elastic restoring force that causes the elastic portion 46 to contract. As a result, the elastic portion 46 applies an elastic restoring force from the abutment position to the non-abutment position (clockwise in Figure 18) to the abutment body 21 via the operating portion 23 and the shaft portion 26. This allows the abutment bodies 21, 22 to be held in the non-abutment position.

[0112] In this way, in the container vehicle 1, as shown in FIG. The holding portion 32 includes an elastic portion 46 that applies an elastic restoring force to the abutting bodies 21 and 22. When the abutment bodies 21, 22 are located at the abutment positions, the elastic portion 46 applies an elastic restoring force to the abutment bodies 21, 22 from the non-abutment position to the abutment positions, and when the abutment bodies 21, 22 are located at the non-abutment positions, the elastic portion 46 applies an elastic restoring force to the abutment bodies 21, 22 from the abutment position to the non-abutment position. The following configuration is also possible.

[0113] According to this configuration, when the abutment stop body 21 is located at the abutment stop position, the elastic portion 46 applies an elastic restoring force to the abutment stop body 21 moving from the non-abutment stop position to the abutment stop position. This makes it possible to hold the abutment stop bodies 21, 22 at the abutment stop position. On the other hand, when the abutment stop body 21 is located at the non-abutment stop position, the elastic portion 46 applies an elastic restoring force to the abutment stop body 21 moving from the abutment stop position to the non-abutment stop position. This makes it possible to hold the abutment stop bodies 21, 22 at the non-abutment stop position.

[0114] (B-2-2) In Fig. 18, the elastic portion 46 is configured to apply an elastic restoring force to the abutment bodies 21, 22 by connecting the operation portion 23 and the vehicle body 11. However, the elastic portion 46 is not limited to this configuration. For example, the elastic portion 46 may be configured to apply an elastic restoring force to the abutment bodies 21, 22 by connecting the abutment body 21 and the vehicle body 11.

[0115] (B-3) For example, the holding portion 32 may be configured to include a regulating body that abuts and stops the abutment bodies 21, 22 in the rotation direction of the abutment bodies 21, 22.

[0116] (B-3-1) As an example of such a configuration, although not particularly limited, the container vehicle 1 may have the configuration shown in Figures 19 to 29. The container vehicle 1 according to Figures 19 to 29 will be described below.

[0117] As shown in Figures 19 and 20, the container vehicle 1 is equipped with a moving part 51 that enables the abutment bodies 21, 22 to rotate relative to the vehicle body 11 and move in the fore-and-aft direction D1, a first abutment part 28c and a second abutment part 28d that are fixed to the vehicle body 11 and abut against the abutment bodies 21, 22 in the fore-and-aft direction D1 as the abutment bodies 21, 22 move in the fore-and-aft direction D1, and a holding part 32 that holds the abutment bodies 21, 22 in the abutment position.

[0118] 19 and 20 (as well as FIGS. 21 to 31), only the first abutment body 21, the moving portion 51, the contact portions 28c and 28d, and the holding portion 32 associated with the first abutment body 21 are shown, and the second abutment body 22, the moving portion, the contact portion, and the holding portion associated with the second abutment body 22 are not shown. Note that the second abutment body 22 may have the same configuration as the first abutment body 21, for example, or may have a different configuration. Furthermore, the moving portion, the contact portion, and the holding portion associated with the second abutment body 22 may have the same configuration as the moving portion 51, the contact portions 28c and 28d, and the holding portion 32 associated with the first abutment body 21, for example, or may have a different configuration.

[0119] The first contact portion 28c is located in front of the first abutment body 21. As a result, the first abutment body 21 moves forward, and the first abutment portion 28c abuts against the first abutted portion 21f of the first abutment body 21, so that the first abutment body 21 is located at a separated position farthest from the container 8 in the front-rear direction D1 (see FIGS. 20(b) and 23).

[0120] The second contact portion 28d is located rearward of the first abutment body 21. As a result, the first abutment body 21 moves rearward, and the second abutment portion 28d abuts against the second abutted portion 21g of the first abutment body 21, whereby the first abutment body 21 is located at an approach position (see FIGS. 19 and 20(a)) closest to the container 8 in the front-rear direction D1.

[0121] In this way, the first abutment body 21 is movable in the front-rear direction D1 between the first abutment portion 28c and the second abutment portion 28d. Specifically, the first abutment body 21 is movable in the front-rear direction D1 between an approach position (see FIGS. 19 and 20(a)) where it is closest to the container 8 in the front-rear direction D1 and a separated position (see FIGS. 20(b) and 23) where it is farthest from the container 8 in the front-rear direction D1.

[0122] Furthermore, a first distance L1 in the front-rear direction D1 between the first contact portion 28c and the second contact portion 28d is longer than a second distance L2 in the front-rear direction D1 (the width of the first contact body 21 in the front-rear direction D1) between the first contacted portion 21f and the second contacted portion 21g of the first contact body 21. This allows the contact body 21 to move in the front-rear direction D1 by a third distance L3 which is the difference between the first distance L1 and the second distance L2.

[0123] Although not particularly limited, as shown in Figures 19 and 20, for example, the moving part 51 may have a first shaft part 26 and a first tubular part 28, and the first tubular part 28 may have a front tubular part 28a that is fixed to the vehicle body 11 in front of the first abutment body 21 and inserted into the first shaft part 26, and a rear tubular part 28b that is fixed to the vehicle body 11 behind the first abutment body 21 and inserted into the first shaft part 26.

[0124] For example, the front and rear cylindrical portions 28a, 28b may support the first shaft portion 26 rotatably and movably in the front-rear direction D1, thereby supporting the first abutment body 21 rotatably and movably in the front-rear direction D1. Also, for example, the first abutment portion 28c may be provided at the rear end of the front cylindrical portion 28a, and the second abutment portion 28d may be provided at the front end of the rear cylindrical portion 28b.

[0125] 19, 21, and 22, the holding portion 32 is provided with a restricting body 47 that restricts the rotation of the first abutment body 21. The restricting body 47 is movable between a restricting position (see FIGS. 19 and 21(a)) where the restricting body 47 abuts and stops the first abutment body 21, which is located at the abutment stop position, in the rotational direction of the first abutment body 21, and a non-restricting position (see FIGS. 21(b) and 23) where the restricting body 47 is separated from the first abutment body 21, which is located at the abutment stop position.

[0126] Furthermore, as shown in Figures 19, 21 and 22, the holding portion 32 includes a support portion 48 that is fixed to the vehicle body 11 (specifically, the left and right frames 14b of the vehicle body frame 14) and supports the regulating body 47 so that it can move in the fore-and-aft direction D1, and a regulating body operating portion 49 that is operated to move the regulating body 47 relative to the support portion 48.

[0127] The support portion 48 may be configured to fix the position of the regulating body 47. Although not particularly limited, for example, the regulating body 47 may have a male thread portion 47e having a male thread formed on the outer periphery thereof, the support portion 48 may have a female thread hole 48a that screws into the male thread portion 47e, and the male thread portion 47e may be fixed to the female thread hole 48a.

[0128] The restrictor operating unit 49 may be configured, for example, to be fixed to the restrictor 47 and to rotate relative to the support unit 48 around an axis in the front-rear direction D1. Although not particularly limited, the restrictor operating unit 49 may be, for example, a handle (e.g., a lever handle) having a grip. When the restrictor operating unit 49 is rotated relative to the support unit 48 around an axis in the front-rear direction D1 and the male screw portion 47e is threadedly engaged with the female screw hole 48a, the restrictor 47 moves in the front-rear direction D1 relative to the support unit 48.

[0129] For example, when the male screw portion 47e is threadedly engaged with the female screw hole 48a and the restrictor 47 moves rearward relative to the support portion 48, the restrictor 47 moves to the restricting position as shown in FIG. 21(a) (see also FIG. 19). When the male screw portion 47e is threadedly engaged with the female screw hole 48a and the restrictor 47 moves forward relative to the support portion 48, the restrictor 47 moves to the non-restricting position as shown in FIG. 21(b) (see also FIG. 23). In this way, the restrictor 47 is movable in the front-to-rear direction D1 between the restricting position and the non-restricting position.

[0130] The regulating body 47 also includes a first regulating portion 47a that abuts against the first abutment body 21 in the rotational direction of the first abutment body 21, and a second regulating portion 47b that abuts against the first abutment body 21 in the front-rear direction D1. When the regulating body 47 is located at the regulating position, the first regulating portion 47a abuts against the first abutment body 21 located at the abutment position in the rotational direction of the first abutment body 21. When the regulating body 47 is located at the regulating position, the second regulating portion 47b abuts against the first abutment body 21 located at the abutment position in the front-rear direction D1.

[0131] The regulating body 47 and the first abutment body 21 may have, for example, engaging portions 47c, 21d that come into contact with each other in the rotational direction of the first abutment body 21 when the regulating body 47 is located at the regulating position and the first abutment body 21 is located at the abutment position. Although not particularly limited, for example, as shown in Fig. 21 , the first engaging portion 21d of the first abutment body 21 may have a recessed portion 21e that is recessed in the front-rear direction D1 (specifically, the rearward direction), and the second engaging portion 47c of the regulating body 47 may have an insertion portion 47d that is inserted into the recessed portion 21e.

[0132] As a result, when the insertion portion 47d is inserted into the recessed portion 21e, the outer periphery of the insertion portion 47d and the inner periphery of the recessed portion 21e come into contact in the rotation direction of the first abutment body 21 at a position away from the axis of rotation of the first abutment body 21 (the axis of the first shaft portion 26) as viewed in the front-rear direction D1. Therefore, the first abutment body 21 located at the abutment position is restricted from rotating by the engagement portions 47c, 21d. In this way, the first restricting portion 47a is formed by the outer periphery of the insertion portion 47d.

[0133] Furthermore, when the insertion portion 47d is inserted into the recessed portion 21e, the rear end of the insertion portion 47d abuts against the bottom of the recessed portion 21e in the front-to-rear direction D1. As a result, the first abutment body 21, which is located at the abutment position, is restricted from moving in the front-to-rear direction D1 (specifically, forward) by the engaging portions 47c, 21d. In this manner, the second restricting portion 47b is formed by the rear end of the insertion portion 47d.

[0134] For example, the depth L4 of the recess 21e may be greater than a third distance L3 (see FIG. 20) that the first abutment body 21 can move in the front-rear direction D1. Furthermore, the first abutment body 21 may be configured to include a first engaging portion 21j (see FIG. 19) that engages with the second engaging portion 47c of the regulating body 47 when the first abutment body 21 is attached to the vehicle body 11 in the second orientation (see FIG. 11).

[0135] Incidentally, while the first abutment body 21 abuts and stops the container 8 in the front-rear direction D1, the holding portion 32 abuts and stops the first abutment body 21 in the rotational direction of the first abutment body 21 in order to hold the first abutment body 21 at the abutment position. As a result, the direction in which the holding portion 32 abuts and stops the first abutment body 21 is different from the direction in which the first abutment body 21 abuts and stops the container 8. Therefore, for example, it is possible to prevent the force required for the holding portion 32 to hold the first abutment body 21 at the abutment position from becoming too large.

[0136] Next, the operation of the first abutment body 21 and the holding portion 32 will be described with reference to Figures 23 to 29. In Figures 23 to 29, a part of the first abutment body 21 is shown in vertical cross section.

[0137] As shown in Fig. 23, when the restricting body 47 is located in the non-restricting position, the restricting body 47 is separated from the first abutment body 21 located in the abutment position. As a result, when the restricting body 47 is located in the non-restricting position, the first abutment body 21 can move between the abutment position and the non-abutment position. In Fig. 23, the first abutment body 21 is located in the abutment position and between the close position and the separated position.

[0138] Then, by operating the restrictor operating portion 49, the restrictor 47 moves in the front-rear direction D1 (specifically, rearward) from the non-restricted position to the restricted position, as shown in Fig. 24. At this time, the rear end of the insertion portion 47d comes into contact with the bottom of the recessed portion 21e in the front-rear direction D1, and the first abutment body 21 is pushed rearward by the restrictor 47. Then, the second abutted portion 21g moves rearward until it abuts against the second abutment portion 28d, and the first abutment body 21 is positioned at the approach position.

[0139] As a result, when the restrictor 47 is positioned at the restricting position, the second restricting portion 47b (see FIG. 21) of the restrictor 47 abuts against and stops the first abutment body 21 from the side opposite to the container 8 in the front-rear direction D1 (specifically, from the front side). Therefore, it is possible to restrict the first abutment body 21 from moving from the approach position to the separated position (specifically, toward the front).

[0140] Moreover, when the regulating body 47 is positioned at the regulating position, the first regulating portion 47a (see FIG. 21) of the regulating body 47 abuts and stops the first abutment body 21 in the rotation direction of the first abutment body 21. When viewed in the front-rear direction D1, the position at which the first regulating portion 47a abuts and stops the first abutment body 21 is away from the axis of rotation of the first abutment body 21 (specifically, the axis of the first shaft portion 26), and therefore, it is possible to restrict the first abutment body 21 from moving from the abutment position toward the non-abutment position.

[0141] In this way, when the restricting body 47 is located at the restricting position, the first abutment body 21 located at the abutment stop position is restricted from rotating by the first restricting portion 47a and from moving in the front-rear direction D1 by the second restricting portion 47b. Therefore, the first abutment body 21 is held at the abutment stop position and the approach position.

[0142] Note that the method is not limited to the method in which the first abutment body 21 is moved to the approaching position by being pushed rearward by the regulating body 47, but for example, the first abutment body 21 located at the separated position may be moved to the approaching position by directly operating the first abutment body 21. In such a method, after the first abutment body 21 is moved to the approaching position, the regulating body 47 may be moved from the non-regulating position to the regulating position.

[0143] Furthermore, for example, when the first abutment body 21 located at the approaching position is separated from the container 8 as shown in Fig. 24, the container 8 may move forward while traveling, for example, as shown in Fig. 25. At this time, the restricting body 47 is located at the restricting position, thereby restricting the first abutment body 21 from moving from the approaching position toward the separated position, and the container 8 is stopped by the first abutment body 21 in the front-rear direction D1.

[0144] In response to this, in order to lower the container 8, the restrictor operating unit 49 is operated, and as shown in Fig. 26, the restrictor 47 is moved forward from the restricting position to the non-restricting position, whereby the first abutment body 21 is moved forward, and as a result, the first abutment body 21 moves away from the container 8 in the front-to-rear direction D1.

[0145] At this time, for example, after the restricting body 47 has moved to the non-restricting position, the first abutting body 21 may be moved forward by being directly operated. Alternatively, for example, the restricting body 47 and the first abutting body 21 may be moved forward together by the outer periphery of the insertion portion 47d and the inner periphery of the recessed portion 21e being in contact with each other under pressure.

[0146] When the restricting body 47 is located at the non-restricting position, it is spaced apart in the front-rear direction D1 from the first abutment body 21, which is located at the abutment position and also at the separated position. As a result, even if the first abutment body 21 is in abutment with the container 8 when the restricting body 47 is located at the restricting position as shown in Fig. 25, the first abutment body 21 can be separated from the container 8 by positioning the restricting body 47 at the non-restricting position as shown in Fig. 26. Therefore, the first abutment body 21 can be smoothly moved from the abutment position to the non-abutment position.

[0147] 27, the first abutment body 21 may abut against the container 8 at a position between the separated position and the approach position. Alternatively, in order to lower the container 8, as shown in FIG. 28, the first abutment body 21 can be separated from the container 8 by moving the first abutment body 21 toward the separated position after positioning the regulating body 47 at the non-regulating position. This allows the first abutment body 21 to be smoothly moved from the abutment position to the non-abutment position while the first abutment body 21 is separated from the container 8.

[0148] Note that a third distance L3 (see FIG. 20) over which the first abutment body 21 can move in the front-rear direction D1 is shorter than the depth L4 (see FIG. 21) of the recessed portion 21e. As a result, as shown in FIG. 29, even if, for example, the container 8 moves rearward while traveling and the first abutment body 21 moves to the approach position accordingly, it is possible to prevent the insertion portion 47d of the regulating body 47 from coming out of the recessed portion 21e of the first abutment body 21. Therefore, the regulating body 47 can reliably abut and stop the first abutment body 21 in the rotational direction of the first abutment body 21.

[0149] In this way, the container vehicle 1, as shown in FIGS. 19 to 29, a vehicle body 11 on which a container 8 can be loaded; an abutment stop body 21 that is movable by rotating about an axis of the first direction D1 between an abutment stop position where the container 8 placed on the vehicle body 11 is abutted and stopped in a first direction (front-rear direction in Figures 19 to 29) D1 and a non-abutment stop position where the container 8 is separated from the vehicle body 11; and a holding portion 32 that holds the abutment body 21 at the abutment position.

[0150] According to this configuration, the abutment stop body 21 rotates around an axis in the first direction D1, and thereby the abutment stop body 21 can move between an abutment stop position where it abuts and stops the container 8 placed on the vehicle body 11 in the first direction D1, and a non-abutment stop position where it is separated from the container 8 placed on the vehicle body 11. Then, the holding portion 32 holds the abutment stop body 21 at the abutment stop position, so the abutment stop body 21 can be held at the abutment stop position.

[0151] In addition, in the container vehicle 1, as shown in FIGS. 19 to 29, The holding portion 32 is provided with a restricting body 47 that restricts the rotation of the abutting stop body 21, The regulating body 47 is movable between a regulating position where it abuts against the abutment stop body 21 located at the abutment stop position in the rotational direction of the abutment stop body 21, and a non-regulating position where it is separated from the abutment stop body 21 located at the abutment stop position. The following configuration is also possible.

[0152] According to this configuration, when the regulating body 47 is located at the regulating position, the abutment stop body 21 located at the abutment stop position is abutted and stopped in the rotational direction of the abutment stop body 21. As a result, the abutment stop body 21 located at the abutment stop position is restricted from rotating, and is therefore held at the abutment stop position.

[0153] On the other hand, when the restricting body 47 is located in the non-restricting position, the restricting body 47 moves away from the abutment stop body 21 located in the abutment stop position, thereby allowing the abutment stop body 21 located in the abutment stop position to move to the non-abutment stop position.

[0154] In addition, in the container vehicle 1, as shown in FIGS. 19 to 29, the abutment body 21 is movable in the first direction D1 between an approach position closest to the container 8 in the first direction D1 and a distance position farthest from the container 8 in the first direction D1, The restriction body 47 is movable in the first direction D1 between the restriction position and the non-restriction position, The regulation body 47 is When the contact stop member 21 is located at the restricting position, the contact stop member 21, which is located at the contact stop position and the approach position, is contacted and stopped in the first direction D1, When the contact member 21 is located at the non-restricted position, the contact member 21 moves away from the contact member 21, which is located at the contact position and the separated position, in the first direction D1. The following configuration is also possible.

[0155] According to this configuration, when the restricting body 47 is located at the restricting position, the restricting body 47 abuts against the abutment stop body 21, which is located at both the abutment stop position and the approach position, in the first direction D1. As a result, when the restricting body 47 is located at the restricting position, it is possible to restrict the abutment stop body 21 from moving from the approach position toward the separated position.

[0156] On the other hand, when the regulating body 47 is located in the non-restricting position, the regulating body 47 moves away in the first direction D1 from the abutment stop body 21, which is located in both the abutment stop position and the separated position. As a result, when the regulating body 47 is located in the non-restricting position, the abutment stop body 21 can be moved from the close position toward the separated position, or the abutment stop body 21 can be moved from the abutment stop position to the non-abutment stop position.

[0157] In addition, in the container vehicle 1, as shown in FIGS. 19 to 29, The regulating body 47 and the abutting body 21 include engaging portions 47c and 21d that come into contact with each other in the rotational direction of the abutting body 21 when the regulating body 47 is located at the regulating position and the abutting body 21 is located at the abutting position, One of the engaging portion 47c of the regulating body 47 and the engaging portion 21d of the abutting body 21 (in FIGS. 19 to 29, the engaging portion 21d of the abutting body 21) has a recessed portion 21e recessed in the first direction D1, and the other (the engaging portion 47c of the regulating body 47) has an insertion portion 47d that is inserted into the recessed portion 21e. The following configuration is also possible.

[0158] According to this configuration, the insertion portion 47d of the engaging portion 47c is inserted into the recessed portion 21e of the engaging portion 21d, so that the engaging portions 47c and 21d can come into contact with each other in the rotational direction of the abutment stop body 21. As a result, the abutment stop body 21 located at the abutment stop position is restricted from rotating by the engaging portions 47c and 21d, and is therefore held at the abutment stop position.

[0159] (B-3-2) For example, in the container vehicle 1 according to Figures 19 to 29, the first engagement portion 21d of the abutment stop body 21 has a recessed portion 21e, and the second engagement portion 47c of the regulating body 47 has an insertion portion 47d that is inserted into the recessed portion 21e. However, the container vehicle 1 is not limited to this configuration. For example, the second engagement portion 47c of the regulating body 47 may have a recessed portion that is recessed in the first direction D1 (specifically, the forward direction), and the first engagement portion 21d of the abutment stop body 21 may have an insertion portion that is inserted into the recessed portion.

[0160] (B-3-3) For example, the container vehicle according to Figures 19 to 29 is configured to include both a holding portion 32 that holds the first abutment body 21 at the abutment stop position and a holding portion that holds the second abutment body 22 at the abutment stop position. However, the container vehicle 1 is not limited to this configuration.

[0161] For example, a configuration may be provided in which a holding portion is provided to hold only one of the first abutment body 21 and the second abutment body 22 at the abutment stop position. In such a configuration, for example, the container vehicle 1 is provided with an operating portion 25 (specifically, a connecting portion 30 that connects the first axle portion 26 and the second axle portion 27), so that as one abutment body 21 (22) is held at the abutment stop position, the other abutment body 22 (21) is also held at the abutment stop position.

[0162] (B-3-4) For example, in the container vehicle 1 according to Figures 19 to 29, the abutting body 21 is configured to be movable in a first direction (front-rear direction) between an approaching position and a separating position relative to the vehicle body 11. However, the container vehicle 1 is not limited to such a configuration. For example, the position of the abutting body 21 in the first direction (front-rear direction) relative to the vehicle body 11 may be fixed (unchangeable).

[0163] (B-3-5) Furthermore, for example, in the container vehicle 1 according to Figures 19 to 29, the regulating body 47 is configured to stop the abutment body 21 in the rotational direction of the abutment body 21 and to stop the abutment body 21 in the first direction D1 when the regulating body 47 is located at the regulating position. However, the container vehicle 1 is not limited to such a configuration.

[0164] For example, the restricting body 47 may be configured such that, when the restricting body 47 is located at the restricting position, it abuts against the abutment stop body 21 in the rotational direction of the abutment stop body 21, but moves away from the abutment stop body 21 in the first direction D1 and does not abut against the abutment stop body 21 in the first direction D1. Although not particularly limited, for example, when the restricting body 47 is located at the restricting position, the rear end of the insertion portion 47d may be located inside the recessed portion 21e and forward of the bottom of the recessed portion 21e.

[0165] (B-3-6) For example, in the container vehicle 1 according to Figures 19 to 29, the regulating body 47 moves between the regulating position and the non-regulating position by moving in the first direction D1. However, the container vehicle 1 is not limited to such a configuration.

[0166] For example, the regulating body 47 may be configured to move between the regulating position and the non-regulating position by moving in the left-right direction D2 or the up-down direction D3. In such a configuration, for example, the regulating body 47 may include a right regulating body located to the right of the abutment stop body 21 and a left regulating body located to the left of the abutment stop body 21, and the right regulating body and the left regulating body may be configured to be movable in the left-right direction D2 or the up-down direction D3 and to abut and stop the abutment stop body 21 in the rotational direction of the abutment stop body 21 by being positioned at the regulating position.

[0167] (B-3-7) For example, in the container vehicle 1 according to Figures 19 to 29, the front tubular portion 28a has a first contact portion 28c at its rear end, and the rear tubular portion 28b has a second contact portion 28d at its front end. However, the container vehicle 1 is not limited to this configuration.

[0168] For example, the body frame 14 (specifically, the left and right frames 14b) located in front of the abutment body 21 may be configured to have the first abutment portion 28c at its rear end. Also, for example, the body frame 14 (specifically, the left and right frames 14b) located behind the abutment body 21 may be configured to have the second abutment portion 28d at its front end. Also, for example, the holding portion 32 (specifically, the support portion 48) may be configured to have the first abutment portion 28c at its rear end.

[0169] (B-3-8) For example, in the container vehicle 1 according to Figures 19 to 29, the first abutted portion 21f is arranged at the frontmost position of the abutting body 21. However, the container vehicle 1 is not limited to such a configuration.

[0170] For example, the first abutted portion 21f may be arranged at a position rearward of the frontmost position of the abutment body 21. Although there is no particular limitation to such a configuration, for example, the abutment body 21 may have a portion recessed in the front-to-rear direction D1 (specifically, rearward), and the first abutted portion 21f may be arranged in the recessed portion.

[0171] (B-3-9) Furthermore, for example, in the container vehicle 1 according to Figures 19 to 29, the second abutted portion 21g is arranged at the rearmost position of the abutting body 21. However, the container vehicle 1 is not limited to such a configuration.

[0172] For example, the second abutted portion 21g may be arranged at a position forward of the rearmost position of the abutment body 21. Although there is no particular limitation to such a configuration, for example, the abutment body 21 may have a portion recessed in the front-to-rear direction D1 (specifically, forward), and the second abutted portion 21g may be arranged in the recessed portion.

[0173] (B-3-10) For example, in the container vehicle 1 according to Figures 19 to 29, the male threaded portion 47e of the regulating body 47 is threadedly engaged with the female threaded hole 48a of the support portion 48, so that the regulating body 47 moves in the first direction D1 between the regulating position and the non-regulating position. However, the container vehicle 1 is not limited to such a configuration.

[0174] For example, the holding unit 32 may be configured to include a drive source that moves the regulating body 47 in the first direction D1. Although not particularly limited, as an example of such a configuration, the holding unit 32 may have the configuration shown in Figures 30 and 31. The drive source 50 may be, for example, a cylinder as shown in Figures 30 and 31, or may be, for example, a motor or the like. Note that the container 8 is not shown in Figures 30 and 31.

[0175] (B-3-11) For example, in the container vehicle 1 according to Figures 19 to 29, the first restricting portion 47a is the outer periphery of the insertion portion 47d, and the second restricting portion 47b is the rear end portion of the insertion portion 47d. However, the container vehicle 1 is not limited to this configuration.

[0176] For example, the first restricting portion may be configured to abut and stop the right and left ends of the abutment stop body 21 located at the abutment stop position in the rotational direction of the abutment stop body 21, and the second restricting portion may abut and stop the front end of the abutment stop body 21 in the first direction D1. Although not particularly limited, as an example of such a configuration, the holding portion 32 may have the configuration shown in Figures 30 and 31.

[0177] As shown in Figures 30 and 31, the regulating body 47 may include, for example, a first regulating portion 47f that abuts and stops the right end portion 21h of the first abutment body 21 located in the abutment stop position in the rotational direction of the first abutment body 21, a first regulating portion 47g that abuts and stops the left end portion 21i of the first abutment body 21 located in the abutment stop position in the rotational direction of the first abutment body 21, and a second regulating portion 47h that abuts and stops the front end portion 21k of the first abutment body 21 in the first direction D1.

[0178] As shown in Fig. 30, when the restricting body 47 is located in the non-restricting position, the restricting body 47 is separated from the first abutment body 21 located in the abutment stop position. This allows the first abutment body 21 to move between the abutment stop position and the non-abutment stop position when the restricting body 47 is located in the non-restricting position. Note that in Fig. 30, the first abutment body 21 is located in the abutment stop position and also in the separated position.

[0179] 31 , one (right) first restricting portion 47f abuts and stops the abutment stop right end portion 21h of the first abutment body 21 in the rotational direction of the first abutment body 21, and the other (left) first restricting portion 47g abuts and stops the abutment stop left end portion 21i of the first abutment body 21 in the rotational direction of the first abutment body 21. In this way, the restricting body 47 can abut and stop the first abutment body 21 in the rotational direction of the first abutment body 21.

[0180] Furthermore, when the first abutment body 21 is located at the abutment stop position, the drive source 50 moves the regulating body 47 rearward toward the regulating position, whereby the second regulating portion 47h abuts and stops the abutment stop front end portion 21k of the first abutment body 21 in the first direction D1. As a result, the regulating body 47 abuts and stops the first abutment body 21 in the first direction D1.

[0181] (B-3-12) For example, in the container vehicle 1 according to Figures 19 to 29, the abutment stop body 21 abuts and stops the container 8 in the fore-and-aft direction D1, and moves between the abutment stop position and the non-abutment stop position by rotating about the fore-and-aft direction D1 as an axis. However, the container vehicle 1 is not limited to such a configuration.

[0182] For example, the abutment stop body 21 may be configured to abut against the container 8 in the left-right direction D2 and to move between the abutment stop position and the non-abutment stop position by rotating about the left-right direction D2 as an axis. Also, for example, the abutment stop body 21 may be configured to abut against the container 8 in the up-down direction D3 and to move between the abutment stop position and the non-abutment stop position by rotating about the up-down direction D3 as an axis.

[0183] (B-3-13) For example, in the container vehicle 1 according to Fig. 19 to Fig. 29, the regulating body 47 and the abutting body 21 may be provided with a screw mechanism that screws together. Although not particularly limited, for example, the insertion portion 47d of the regulating body 47 may be provided with a male thread on its outer periphery, and the recessed portion 21e of the abutting body 21 may be provided with a female thread on its inner periphery that screws together with the male thread of the insertion portion 47d.

[0184] (C) Furthermore, in the container car 1 according to the above embodiment, the entire abutment bodies 21, 22 are configured to be positioned below the placement surfaces 14c, 14d when the abutment bodies 21, 22 are positioned in the non-abutment positions. However, the container car 1 is not limited to this configuration. For example, a portion of the abutment bodies 21, 22 may be configured to be positioned above the placement surfaces 14c, 14d when the abutment bodies 21, 22 are positioned in the non-abutment positions.

[0185] (D) Furthermore, in the container vehicle 1 according to the above embodiment, when the abutment bodies 21, 22 are positioned in the abutment position, the insertion portion 33 is inserted into the tube openings 29a, 29b and the first shaft opening 27a, and when the abutment bodies 21, 22 are positioned in the non-abutment position, the insertion portion 33 is inserted into the tube openings 29a, 29b and the second shaft opening 27b. In other words, when the abutment bodies 21, 22 are positioned in the abutment position and the non-abutment position, the tube openings 29a, 29b into which the insertion portion 33 is inserted are the same, and the shaft openings 27a, 27b into which the insertion portion 33 is inserted are different. However, the container vehicle 1 is not limited to this configuration.

[0186] For example, the shaft portion 27 may have a third shaft opening into which the insertion portion 33 is inserted, and the tubular portion 29 may have a third tubular opening that communicates with the shaft opening and is inserted into the insertion portion 33 when the abutment bodies 21, 22 are located at the abutment position, and a fourth tubular opening that communicates with the tubular opening and is inserted into the insertion portion 33 when the abutment bodies 21, 22 are located at the non-abutment position. In other words, the shaft opening into which the insertion portion 33 is inserted may be the same when the abutment bodies 21, 22 are located at the abutment position and the non-abutment position, and the tubular opening into which the insertion portion 33 is inserted may be different.

[0187] (E) In addition, in the container vehicle 1 according to the above embodiment, the tubular portions 28, 29 are configured to be cylindrical. However, the container vehicle 1 is not limited to this configuration. For example, the tubular portions 28, 29 may be configured to be formed of blocks (e.g., cubic blocks, rectangular parallelepiped blocks) having cylindrical through-holes.

[0188] (F) In addition, in the container car 1 according to the above embodiment, the retaining portion 33b is configured to be movably connected to the insertion body portion 33a so as to be movable between the retaining position and the insertion / removal position. However, the container car 1 is not limited to this configuration. For example, the retaining portion 33b may be configured to be detachable from the insertion body portion 33a so as to be attachable to the insertion body portion 33a at the retaining position and the insertion / removal position.

[0189] (G) In addition, in the container vehicle 1 according to the above embodiment, the insertion portion 33 is configured to include an insertion main body portion 33a that is inserted across the shaft portion 27 and the tubular portion 29, and a retaining portion 33b that is connected to the end of the insertion main body portion 33a. However, the container vehicle 1 is not limited to this configuration.

[0190] For example, the insertion portion 33 may not be provided with the retaining portion 33b. Although not particularly limited, one example of such a configuration is that the insertion portion 33 is a male screw member, and the threaded portion of the male screw member is inserted into the cylindrical opening of the tubular portion 29 and threadedly engages with the female screw hole of the shank 27. According to such a configuration, the threaded portion of the male screw member forms an insertion main body portion 33a that is inserted across the shank 27 and the tubular portion 29. Moreover, according to such a configuration, the insertion portion 33 is fixed to the shank 27 by a screw mechanism, and therefore does not require the retaining portion 33b.

[0191] (H) Furthermore, in the container car 1 according to the above embodiment, when the abutment stop bodies 21, 22 are located in the abutment stop positions, portions of the abutment stop bodies 21, 22 are positioned above the loading surfaces 14c, 14d. However, the container car 1 is not limited to this configuration. For example, when the abutment stop bodies 21, 22 are located in the abutment stop positions, the entire abutment stop bodies 21, 22 may be positioned above the loading surfaces 14c, 14d.

[0192] (I) Furthermore, in the container vehicle 1 according to the above embodiment, the abutment bodies 21, 22, at least a portion of which is disposed above the loading surfaces 14c, 14d when positioned at the abutment position and the entirety of which is disposed below the loading surfaces 14c, 14d when positioned at the non-abutment position, are configured to abut and stop the front end of the container 8. However, the container vehicle 1 is not limited to this configuration.

[0193] The abutment body, which is positioned at least partially above the loading surfaces 14c, 14d when positioned in the abutment position and is positioned entirely below the loading surfaces 14c, 14d when positioned in the non-abutment position, may be configured to abut against the rear end of the container 8, or may be configured to abut against the middle part of the container 8 in the fore-and-aft direction D1, for example.

[0194] (J) In addition, in the container vehicle 1 according to the above embodiment, the abutment bodies 21, 22 that are movable between an abutment position and a non-abutment position abut and stop the container 8 in the fore-and-aft direction D1 and rotate around the axis of the fore-and-aft direction D1. However, the container vehicle 1 is not limited to this configuration.

[0195] For example, the abutment stop bodies 21, 22 movable between the abutment stop position and the non-abutment stop position may be configured to abut and stop the container 8 in the left-right direction D2 and rotate around the left-right direction D2 as an axis. Also, for example, the abutment stop bodies 21, 22 movable between the abutment stop position and the non-abutment stop position may be configured to abut and stop the container 8 in the up-down direction D3 and rotate around the up-down direction D3 as an axis.

[0196] (K) Furthermore, in the container vehicle 1 according to the above embodiment, the container vehicle 1 is a combination vehicle 1, and the abutting bodies 21, 22, at least a portion of which is disposed above the loading surfaces 14c, 14d when in the abutting position and which are disposed entirely below the loading surfaces 14c, 14d when in the non-abutting position, are provided only on the towed vehicle 10. However, the container vehicle 1 is not limited to this configuration.

[0197] For example, the container vehicle 1 may be a combination vehicle 1, and the abutting body, at least a portion of which is positioned above the loading surface when in the abutting position and the entirety of which is positioned below the loading surface when in the non-abutting position, may be provided only on the towing vehicle 2. Alternatively, the container vehicle 1 may be a combination vehicle 1, and the abutting body, at least a portion of which is positioned above the loading surface when in the abutting position and the entirety of which is positioned below the loading surface when in the non-abutting position, may be provided on both the towing vehicle 2 and the towed vehicle 10.

[0198] Also, for example, the container vehicle may be a towing vehicle 2 equipped with an abutting body that is at least partially positioned above the loading surface when in the abutting position and is entirely positioned below the loading surface when in the non-abutting position. Also, for example, the container vehicle may be a towed vehicle 10 equipped with an abutting body that is at least partially positioned above the loading surface when in the abutting position and is entirely positioned below the loading surface when in the non-abutting position.

[0199] Furthermore, for example, the container vehicle may be a self-propelled vehicle that has no towing capability, and is equipped with a stop body that is positioned at least partially above the loading surface when in the stop position and positioned entirely below the loading surface when in the non-stop position.

[0200] (L) Furthermore, in the container vehicle 1 according to the above embodiment, the towing vehicle 2 is configured to be able to load the container 8. However, the container vehicle 1 is not limited to this configuration. For example, the towing vehicle 2 may be configured to be unable to load the container 8, and only the towed vehicle 10 may be configured to be able to load the container 8.

[0201] (M) In addition, in the container car 1 according to the above embodiment, the operating unit 25 connects the first abutment body 21 and the second abutment body 22, and the first abutment body 21 and the second abutment body 22 are configured to move in conjunction with each other. However, the container car 1 is not limited to this configuration. For example, the operating unit 25 may be configured to separate the first abutment body 21 and the second abutment body 22, and the first abutment body 21 and the second abutment body 22 may each move individually between an abutment position and a non-abutment position.

[0202] (N) Furthermore, the container vehicle 1 according to the above embodiment is equipped with a drive switching unit 6, and the drive switching unit 6 is configured to be switchable between a first state in which the drive of the engine 5 is transmitted to the wheels 3c, and a second state in which the drive of the engine 5 is transmitted to the cargo handling device 4. However, the container vehicle 1 is not limited to such a configuration.

[0203] For example, the container vehicle 1 may not be provided with the drive switching unit 6. Although not particularly limited, one example of such a configuration is that the container vehicle 1 may be configured to be able to transmit the drive of the engine 5 to the wheels 3c and the cargo handling device 4 simultaneously.

[0204] (O) Furthermore, the container vehicle 1 according to the above embodiment is configured to include a position detection unit 31 that detects that the abutment bodies 21, 22 are located in the abutment position. However, the container vehicle 1 is not limited to this configuration.

[0205] For example, the container vehicle 1 may not be provided with a position detection unit 31 that detects that the abutment bodies 21, 22 are located in the abutment position. An example of such a configuration is not particularly limited, but may be provided with a position detection unit that detects that the abutment bodies 21, 22 are located in the non-abutment position.

[0206] In such a configuration, for example, the output unit 43 may be configured to output an alarm when the position detection unit 31 does not detect the abutment bodies 21, 22 in the non-abutment position and the drive switching unit 6 has switched to the second state (a state in which the drive of the engine 5 is transmitted to the cargo handling device 4). In addition, in such a configuration, for example, the output unit 43 may be configured to output an alarm when the position detection unit 31 detects the abutment bodies 21, 22 in the non-abutment position and the drive switching unit 6 has switched to the first state (a state in which the drive of the engine 5 is transmitted to the wheels 3c).

[0207] (P) In addition, in the container vehicle 1 according to the above embodiment, the output unit 43 is configured to output an alarm based on the detection of the abutment bodies 21, 22 by the position detection unit 31 and the switched state of the drive switching unit 6. However, the container vehicle 1 is not limited to such a configuration.

[0208] For example, the output unit 43 may be configured not to output an alarm based on the detection of the abutment bodies 21, 22 by the position detection unit 31 and the state switched by the drive switching unit 6. Although not particularly limited, one example of such a configuration may be a configuration in which the state of the drive switching unit 6 is switched by the control unit 42 based on the detection by the position detection unit 31.

[0209] For example, the drive switching unit 6 may be configured such that, when the position detection unit 31 detects the abutment bodies 21, 22 in the abutment stop positions, the control unit 42 switches the drive switching unit 6 to the first state (a state in which the drive of the engine 5 is transmitted to the wheels 3c). Also, for example, the drive switching unit 6 may be configured such that, when the position detection unit 31 does not detect the abutment bodies 21, 22 in the abutment stop positions, the control unit 42 switches the drive switching unit 6 to the second state (a state in which the drive of the engine 5 is transmitted to the cargo handling device 4).

[0210] (Q) In addition, in the container vehicle 1 according to the above embodiment, the abutting bodies 21, 22 are configured to be housed in the recess 14e and to be positioned so as to be able to guide the container roller 8a when they are in the non-abutting position. However, the container vehicle 1 is not limited to this configuration.

[0211] The abutment bodies 21, 22 may be configured, for example, to be disposed forward of the front end of the vehicle body 11 when positioned in the non-abutment position, or may be configured, for example, to be disposed rearward of the rear end of the vehicle body 11. In such a configuration, for example, the vehicle body 11 may not be provided with the recess 14e.

[0212] Further, for example, the abutment bodies 21, 22 may be configured to be housed in the recess 14e and to be positioned so as not to guide the container roller 8a when they are in the non-abutment position. In such a configuration, the abutment bodies 21, 22 do not have the abutment guide surface 21a.

[0213] (R) In the container car 1 according to the above embodiment, the abutment stop guide surface 21a is configured to be flat. However, the container car 1 is not limited to this configuration. For example, the abutment stop guide surface 21a may be configured to be uneven.

[0214] (S) In addition, in the container vehicle 1 according to the above embodiment, the abutment bodies 21, 22 are configured to be detachable from the vehicle body 11 so as to be attachable to the vehicle body 11 in a first orientation and a second orientation. However, the container vehicle 1 is not limited to such a configuration.

[0215] For example, the abutment bodies 21, 22 may be configured to be non-detachable from the vehicle body 11. In such a configuration, for example, the recess 14e may be configured to have a shape corresponding to the abutment bodies 21, 22 so as to reduce the gap between the recess 14e and the abutment bodies 21, 22 positioned in the non-abutment position.

[0216] (T) Furthermore, in the container vehicle 1 according to the above embodiment, both the first abutment body 21 and the second abutment body 22 are configured to be detachable from the vehicle body 11 so as to be attachable to the vehicle body 11 in a first orientation and a second orientation. However, the container vehicle 1 is not limited to such a configuration. For example, one of the first abutment body 21 and the second abutment body 22 may be configured to be detachable from the vehicle body 11 so as to be attachable to the vehicle body 11 in a first orientation and a second orientation, and the other may be configured to be non-detachable from the vehicle body 11.

[0217] (U) In addition, in the container vehicle 1 according to the above embodiment, the first abutment body 21 and the second abutment body 22 are configured to have the same shape when viewed in the left-right direction D2. However, the container vehicle 1 is not limited to this configuration. For example, the first abutment body 21 and the second abutment body 22 may be configured to have different shapes when viewed in the left-right direction D2.

[0218] (V) In addition, in the container vehicle 1 according to the above embodiment, the operating units 23, 24 are configured to move relative to the vehicle body 11 when operated, and the abutment bodies 21, 22 are interlocked with the operating units 23, 24. However, the container vehicle 1 is not limited to such a configuration.

[0219] For example, the operation units 23, 24 may be configured as switches or buttons, and when operated, the abutment bodies 21, 22 may be moved between the abutment position and the non-abutment position by a drive source (for example, a cylinder, a motor, etc.). In other words, the abutment bodies 21, 22 may not be configured to move in conjunction with the operation units 23, 24.

[0220] (W) In addition, in the container vehicle 1 according to the above embodiment, the abutment bodies 21, 22 and the operating units 23, 24 are fixed to the axle portions 26, 27, and are thereby fixed via the axle portions 26, 27. However, the container vehicle 1 is not limited to this configuration. For example, the operating units 23, 24 may be directly fixed to the abutment bodies 21, 22.

[0221] (X) For example, the order of execution of each step, such as the operations, procedures, steps, and stages, in the methods and apparatuses shown in the claims, specifications, and drawings, can be implemented in any order, as long as the result of a previous step is not used in a subsequent step. For example, even if a description is made using "first," "next," etc. for convenience, this does not mean that the steps must be executed in that order. [Explanation of symbols]
