Description

  The present invention relates to a wing vehicle in which a wing plate in which a roof plate portion and a side plate portion of a closed box type carrier are integrated is provided on both sides of the carrier so as to be openable and closable. The present invention relates to a wing plate presser device that is mounted along the vertical direction on the outer side of the lift plate of the cargo bed in order to prevent the bulge from bulging outward.

  A wing vehicle is a luggage carrier vehicle having a closed box-shaped carrier. As shown in FIG. 1 and FIG. 2, the sealed box-shaped cargo bed includes a pair of left and right tilt plates 73 connected to both sides of a base plate 71 through a plurality of hinges 72 so as to be openable and closable laterally, A front plate 74 and a rear plate 75 erected and fixed at both ends in the front-rear direction of the plate 71, and a center connecting the upper end portions of the front plate 74 and the rear plate 75 and the central portion in the vehicle width direction. A frame 76 and a wing plate 77 that is integrally integrated with a top plate portion 77a and a side plate portion 77b so as to be substantially L-shaped in a side view, and is pivotally connected to the center frame 76. ing. With the wing plate 77 closed, the side plate portion 77b of the wing plate 77 and both end portions in the front-rear direction of the tilt plate 73 are locked to the front plate 74 and the rear plate 75 by the locking devices 78 and 79, respectively.

  When the wing vehicle is inclined in the vehicle width direction both during travel and when it is stopped, the side plate portion 77b of the wing plate 77 bulges outward. In order to prevent this, one or a plurality of wing plate pressing devices are attached to the outside of the tilt plate 73, and the pressed plate 81 attached to the lower end of the side plate portion 77b of the wing plate 77 is pressed from the outside. In the wing plate pressing device described above, there are a type in which the pressing plate slides in the vertical direction and a type in which the pressing plate rotates in the vehicle width direction within a vertical plane. The former has the advantage that the overall thickness of the device can be reduced, but if the side plate of the wing plate bulges outward and the bulge amount is greater than a certain value, the wing alone can be used by the operator. The plate retainer cannot be operated.

  As one of the latter wing plate pressing devices A ', the one described in Patent Document 1 is known. 18 and 19, the base member V ′ of the wing plate pressing device A ′ has a shape in which a concave portion 82 is provided at the center so that the base member V ′ can be fitted into the concave portion 73 a formed in the tilt plate 73. A bracket member 83 is fixed to the bottom surface of the recess 82 of the base member V ′, and a hook (locked claw) 84 is fixed to the bracket member 83. The pressing member D ′ is supported by the lower end portion of the bracket member 83 so as to be rotatable about the first fulcrum shaft 85, and the upper end portion thereof is bent toward the front side, and the concave portion 82 of the base member V ′. A pressing portion 87 for sandwiching the presser plate 81 is formed between the upper flange portion 86 and the portion of the pressing member D ′ corresponding to the hook 84 so that the hook 84 faces the front side. An opening 88 is formed.

The first lock member R ₁₁ ′ is connected to a second fulcrum shaft 89 of the bracket member 83 between the hook 84 and the first fulcrum shaft 85 so that the upper end portion (tip portion) is rotatable. Further, a long hole 91 in the longitudinal direction is provided below. The second locking member R ₁₂ ′ has a hook 84 inserted and locked in a locking hole 92 at its upper end (tip), and its lower end inserted through the long hole 91 of the first locking member R ₁₁ ′. It is connected to the first lock member R ₁₁ ′ via the connecting pin 93. The first lock member R ₁₁ ′ is elastically provided with a compression spring 94 between the second fulcrum shaft 89 and the connection pin 93 in order to bias the connection portion with the second lock member R ₁₂ ′ downward. Has been.

The first lock member R ₁₁ ′ is moved beyond the “neutral position” where the locking point 95 between the second lock member R ₁₂ ′ and the hook 84, the second fulcrum shaft 89, and the connecting pin 93 are aligned. When the base member V ′ is turned, the second lock member R ₁₂ ′ is maintained in the locked state in which the second lock member R ₁₂ ′ is engaged with the hook 84 by the restoring force of the compression spring 94. Note that, in FIGS. 18 and 19, 96 'shows a pair of pivot shaft bracket which is fixed to, in FIG. 19 (b), H _1' member D pressing to support the second pivot shaft 89, The height from the recessed part 82 of the base member V 'to the 2nd fulcrum shaft 89 is shown.

In the locked state, the wing plate pressing device has a structure in which the base member V ′, the bracket member 83, the first lock member R ₁₁ ′ and the second lock member R ₁₂ ′ are stacked in a superimposed manner. A structure in which a second fulcrum shaft 89 that supports the first lock member R ₁₁ ′ so as to be rotatable with respect to the base member V ′ is arranged at a position that is much higher than the presser member D ′ with respect to the member V ′. is there. For this reason, the total height (H ₀ ′) of the wing plate presser A ′ is increased. The loading platform width in the wing vehicle is wider than the total height of the wing plate presser A ′ attached to the outside of the tilt plate 73 with respect to the loading platform width, and it is necessary to keep this widened vehicle width within the regulation value. is there.

Therefore, it is necessary to form a recess 73a that accommodates most of the thickness direction of the wing plate pressing device A ′ by machining the tilt plate 73 formed by integrating and stacking the metal extrusion molding materials. There is a problem that not only labor and cost are required for machining, but also the strength of the tilt plate 73 is reduced due to the formation of the recess 73a.
FIG. 3 of JP-A-9-119410

  An object of the present invention is to reduce the overall height of a wing plate pressing device mounted on the outer side of a tilting plate of a wing wheel so that it can be mounted on the outer side of the tilting plate as it is.

  The invention of claim 1 for solving the above-described problem is a wing vehicle in which a wing plate in which a top plate portion and a side plate portion of a closed box type carrier are integrated is provided on both sides of the carrier so as to be opened and closed. A wing plate presser device that is mounted along the vertical direction on the outer side of the tilt plate of the cargo bed to prevent the center portion in the front-rear direction of the side plate portion of the wing plate from bulging outward. In order to hold the base member, which has a pawl and is fixed to the outside of the tilt plate, and the presser plate provided at the lower end of the side plate portion of the wing plate, the upper member opens and closes to the base member. A presser member that is movably connected; and a lock member that includes a lock claw that can be locked with the locked claw and that is connected to the presser member via a link member. Lock the pawl to the pawl of the base member and In the locked state in which the lock member is rotated beyond the neutral position, the pressed plate is pressed between the base member and each upper end portion of the presser member. The connection point with the presser member, which is the rotation fulcrum of the link member, is arranged within the thickness range of the presser member so that the presser member and the lock member can be substantially overlapped, and the overall thickness is reduced. It is characterized by being.

  According to the first aspect of the present invention, in the locked state, the connection point of the link member with the presser member, which is the rotation fulcrum of the link member, is disposed within the thickness range of the presser member. Since the three members of the presser member, the lock member, and the link member are arranged so that they can be substantially overlapped, the overall thickness of the wing plate presser device can be reduced. As a result, it can be mounted directly on the outside of the tilt plate.

  According to a second aspect of the present invention, in the first aspect of the present invention, the base member has a locking claw formed at the upper end portion, and a fulcrum plate portion serving as a rotation fulcrum of the presser member at the lower end portion. A bracket member that is integrally formed by standing on the front side is fixed, and an opening obtained by inserting the entire bracket member is formed in the presser member.

  According to the invention of claim 2, since the thickness of the bracket member does not increase the overall thickness of the wing plate pressing device, the overall thickness of the wing plate pressing device can be further reduced.

  According to a third aspect of the present invention, in the first or second aspect of the present invention, the locking claw is integrally formed on the back side of the upper end portion of the lock member, and is locked with the locking claw in the locked state. The to-be-latched claw is configured to be covered with a lock member.

  According to the third aspect of the present invention, in the locked state, there is a member in which the locked claw formed integrally with the base member is covered with the lock member, and the member largely protrudes from the upper surface of the wing plate pressing device to the near side. This eliminates the overall thickness of the wing plate presser.

  According to a fourth aspect of the present invention, in the invention according to any one of the first to third aspects, the tension spring is connected between the connecting portion of the link member on the side opposite to the fulcrum of the link member and the back surface of the lock member. The locked state is maintained by the restoring force of the tension spring, and the link member is covered with the lock member in the locked state. For this reason, since the link member is covered with the lock member in the locked state, the link member is protected.

  According to a fifth aspect of the present invention, in any one of the first to fourth aspects of the present invention, the lock member is provided with an external stop mechanism that maintains a locked state with respect to the presser member. For this reason, since the overall thickness of the wing plate presser is made as thin as possible, the inclination angle of the lock member with respect to the base member in the neutral position is reduced, and the reliability of the lock in the locked state of the wing plate presser is somewhat reduced. However, the lock state of the presser device can be ensured by adopting the external stop mechanism that keeps the lock member locked to the presser member.

  According to a sixth aspect of the present invention, in any one of the first to fifth aspects of the present invention, when the tilt plate is reversed, the lock member rotates with respect to the presser member so that the upper end of the lock member is located at the back of the loading platform. It is characterized by having a rotation preventing member that prevents the projection from projecting to the side. For this reason, when the tilting plate is reversed, it is possible to prevent the locking member from colliding with various devices such as the fuel tank existing on the reversing locus of the locking member constituting the wing plate pressing device. Equipment is protected.

  According to the present invention, the connection point with the presser member, which is the rotation fulcrum of the link member, is arranged within the thickness range of the presser member so that the presser member and the lock member can substantially overlap in side view, Since the overall thickness is reduced, it can be directly mounted on the outer side of the tilt plate without machining a recess in the tilt plate.

  Hereinafter, the present invention will be described in more detail with reference to the best mode.

The base member V ₁ was formed of a flat metal plate, pressing surface 1 to the portion to be the upper portion in the attached state is formed by raised slightly on the surface. A bracket member B ₁ is integrally fixed to the base member V ₁ at substantially the center in both the vertical direction and the width direction by welding. The bracket member B ₁ is bent to a front side so that the upper end of the metal plate is bent at an acute angle with the base member V ₁ to form the locked claw 2. Thus, both side portions in the width direction are bent at a substantially right angle toward the front side to form a fulcrum plate portion 3 (see FIGS. 3 and 4).

The holding member D ₁ is formed by bending a metal plate, and an opening 4 is formed for allowing the entire bracket member B ₁ to face the front side without interfering with the bracket member B ₁ in the locked state. In addition, both ends in the width direction of the metal flat plate are bent substantially at right angles to the front side over the entire length in the vertical direction to form an outer folding plate portion 5, and the outer folding in the substantially lower half portion in the vertical direction. The inner bent portion that is bent to the near side inside the bent plate portion 5 is a portion that functions as the fulcrum plate portions 6 and 7. At the upper end of the presser member D ₁ , a presser plate 81 is inserted between the presser surface 1 of the base member V ₁ in the “locked state” where the presser member D ₁ and the base member V ₁ are substantially parallel. A presser portion 8 for forming a space that can be formed is formed (see FIG. 6). As shown in FIGS. 3 to 6, the lower end portion of the pressing member D ₁ is connected to a pair of fulcrum plate portions 3 formed on the bracket member B ₁ so as to be rotatable in the vehicle width direction via a fulcrum shaft 10. Has been. With this configuration, the pressing member D ₁ is rotatably connected to the base member V ₁ . The fulcrum shaft 10 connecting the lower end portion of the presser member D ₁ and the pair of fulcrum plate portions 3 penetrates the lower end portions of both the outer bent plate portion 5 and the fulcrum plate portion 6 of the presser member D _1. Yes. 3, 4, and 6, reference numeral 9 denotes a resin plate fixed to the back surface side of the pressing portion 8 of the pressing member D ₁ .

The lock member R ₁ is connected to the pair of fulcrum plate portions 7 of the presser member D ₁ via the link member L ₁ . The lock member R ₁ is a member formed by bending a metal plate so that the cross-section is a flat U-shape, and both end portions in the width direction of the plate-like main body plate portion 11 are on the back side. The folded plate portion 12 is bent, and only the upper end portion is partially narrower than the other portions, and the locking claw 13 is connected to the locked claw 2 on the back side. The main body plate portion 11 has an acute angle so that it can be locked and is integrally attached by welding. The widths of both the pawl 2 and the pawl 13 are set so that both the pawl 2 and the pawl 13 avoid the interference with the presser member D ₁ in the “locked state”. It is formed to be slightly narrower than the width of _one opening 4 (see FIG. 5). Here, as shown in the schematic cross-sectional view of FIG. 9, the width of the lock member R ₁ is smaller than the inner width of the outer bent plate portion 5 of the presser member D ₁ , in "bent plate portion 12 of the locking member R ₁ is located inside the outer bent plate portion 5 of the pressing member D _1, and the member D ₁ holding the locking member R ₁ in a side view may substantially overlap It has a structure like this.

The rear surface of the locking member R ₁ of the main plate portion 11, cross section is fixed connecting bracket 14 is that the shape of the substantially C, the oppositely disposed pair of upright plates 15 in the longitudinal direction, the locking member R ₁ A long hole 16 is formed along the longitudinal direction (vertical direction when the pressing device A ₁ is mounted), and a hooking piece 18 for hooking one end of the tension spring 17 is formed at the upper end of the connecting bracket 14. ing. On the other hand, the link member L ₁ includes a link body 20 in which a pair of link parts 21 are integrally connected by a connection plate part 22, and a connection pin 24 that connects tip ends of the pair of link parts 21. The base end portion of each link portion 21 of the link body 20 is connected to the fulcrum plate portion 7 of the pressing member D ₁ via a pair of fulcrum pins 23, and the connecting pin 24 connecting the distal end portion of each link portion 21. Are inserted into a pair of long holes 16 formed in the connecting bracket 14 on the back surface of the lock member R ₁ . Further, a tension spring 17 for maintaining the “locking state” of the presser device A ₁ is hooked between the connecting pin 24 and the hooking piece 18 of the connecting bracket 14. Here, as shown in FIGS. 6 to 9, in order to reduce the thickness of the presser device A _1, the shaft center of the pressing member D ₁ and the link member L ₁ and the fulcrum pin 23 which connects the, the retainer is disposed within the thickness range of the members D _1. With this configuration, the lock member R ₁ is coupled to the pair of fulcrum plate portions 7 of the pressing member D ₁ via the link member L ₁ .

Therefore, as shown in FIG. 3 and FIG. 4, as shown by the two-dot chain line in FIG. 7 after the holding member D ₁ is in the “open state” and the tilt plate 73 is rotated downward. The locking point between the locking claw 13 and the locked claw 2 in a state where the locking claw 13 at the upper end of the lock member R ₁ and the locked claw 2 fixed to the base member V ₁ are locked. When the lock member R ₁ is rotated toward the base member V ₁ centering on P ₁ , the “neutral position (in which the action line of the tension spring 17 and each link portion 21 of the link member L ₁ are parallel to each other). The position shown by the solid line in FIG. 7) ”is exceeded and the“ locked state ”shown in FIGS. 6 and 8 is reached. In the "locked state", and the connecting pin 24 of the hinge member H _1, located fulcrum pin 23 of the hinge member H ₁ is between the catching piece 18 of the tension spring 17 which is formed on the rear surface of the locking member R _1, Rock member R ₁ is almost parallel to the base member V _1, by the restoring force of the tension spring 17, and Hikakaritometsume second locking claws 13 and the base member V ₁ of the locking member R ₁ is engaged The “locked state” is maintained.

In the "locked state", as shown in FIG. 9 (b), the pressing member D ₁ and the locking member R ₁ and has substantially overlap in side view, yet the bracket member is secured to the base member V ₁ B ₁ is not entering the opening 4 of the pressing member D _1, the thickness of the bracket member B ₁ represents becomes irrelevant arrangement in overall height (H ₀₎ of the wing plate presser device a ₁ of the "locked state". The link member L ₁ and the fulcrum pin 23 connecting the link member L ₁ to the pressing member D ₁ are both space portions formed by the main body plate portion 11 and the bracket member B _{1 of the} lock member R _1. Is housed in. With these configurations, the overall height (H ₀ ) of the wing plate presser device A ₁ in the “locked state” can be reduced, and the presser device A ₁ can be made thinner.

In Example 1, the height (H ₁ ) from the upper surface of the base member V ₁ to the axis of the fulcrum pin 23 is (12 mm) in FIG. 9 (A), and the pressing member D ₁ and the locking member R ₁ The heights (H ₂ ) and (H ₃ ) are (17 mm) and (13.5 mm), respectively, and the total height (H ₀ ) of the wing plate presser A ₁ is (20 mm). For this reason, the base member V ₁ can be mounted on the outside of the tilt plate 73 by the plurality of mounting bolts 25 without machining the outer surface of the tilt plate 73.

The lock at the lower end of the member R _1, in a state where the Hikakaritometsume 2 secured to the base member V ₁ and the locking claw 13 of the locking member R ₁ is locked, the locking member R ₁ is a bracket member A slip-off prevention device E ₁ for preventing the slippage from B ₁ and ensuring the “lock state” is mounted. The stopper device E ₁ is slidably received in the stopper plate housing portion 27 at the lower end of the lock member R ₁ in a state of being biased upward by the restoring force of the compression spring 26; A locked portion 29 formed at the lower end portion of the pair of left and right fulcrum plate portions 3 of the bracket member B ₁ and locked with the locking portion 28a at the upper end of the outer stopper plate 28 in the “locked state”. Composed. Sliding guide part 27a which opens on both sides is formed in the outer stopper plate accommodating portion 27 of the locking member R _1, slidably received slide piece 28b provided on both sides of the outer stopper plate 28 to the slide guide portion 27a Has been. On the other hand, the front end surface of the lower end portion of the pair of left and right fulcrum plate portions 3 of the bracket member B ₁ becomes a sliding surface 31 that slides the upper end surface (tip surface) of the outer stopper plate 28 immediately before locking. In addition, the large stepped portion at the end of the sliding surface 31 is a locked portion 29.

For this reason, when the lock member R ₁ is rotated to the base member V ₁ side beyond the “neutral position”, the outer stop plate 28 that has slid on the sliding surface 31 of the fulcrum plate portion 3 is slid. When the end of the moving surface 31 is passed, the outer retaining plate 28 protrudes upward by the restoring force of the compression spring 26 and is latched by the latched portion 29 formed on the fulcrum plate portion 3, and the lock member R _1. Can be prevented from coming out of the "locked state". Moreover, by the generation of sound "click" when the outer stop plate 28 passes through the end portion of the sliding surface 31, it can be confirmed that the operator is stopped device E ₁ out acts.

Further, in the first embodiment, the latching claw 2 is fixed to the base member V ₁ with an acute angle obliquely upward, and the latching claw 13 is inclined on the back side of the distal end portion of the lock member R _1. It is formed at an acute angle with respect to the main body plate portion 11 downward. With this structure, the locking claw 13 of the locking member R ₁ is locked to the locked claw 2 of the base member V ₁ when locked. Thus, since the lock member R ₁ is rotated and locked to the base member V ₁ side, the engaging portion is difficult to come off. Further, the locking claw 13 is integrally formed on the back surface side of the distal end portion of the lock member R ₁ , and the locked claw 2 does not protrude from the upper surface of the lock member V _{1 in} the “locked state”. Even with this structure, the wing plate presser A ₁ can be thinned.

In the locking structure of the locked claw 2 and the locking claw 32 shown in FIG. 10, only the distal end portion of the lock member R ₁ is formed in a flat cylindrical shape, and the flat cylindrical portion is the locking claw 32. It has become. Therefore, there is an advantage that a more reliable locking structure between the locking claw 32 and Hikakaritometsume second locking member R ₁ at the time of locking.

In the wing plate presser device A 1 having the configuration of the first embodiment, in order to avoid interference with the bracket member B ₁ in the “locked state”, the entire length of the wing plate presser device A ₁ excluding the presser portion 8 at the upper end of the presser member D ₁ is provided. An opening 4 is formed. When the tilting plate 73 is reversed due to the opening 4, as shown in FIG. 15, it is connected via the pressing member D ₂ (D ₁ ) and the hinge member H ₂ (H ₁ ). The lock member R ₂ (R ₁ ) is rotated clockwise in the state shown in FIG. 15, and the tip of the lock member R ₂ (R ₁ ) enters the opening 4, so that the tilt plate 73 is reversed. In the state, the obliquely upper portion of the lock member R ₂ (R ₁ ) protrudes to the back side of the loading platform, collides with various devices G such as a fuel tank existing in the portion, and damages or damages the various devices. There is a bug that will let you. The locking member R ₂ (R ₁ ) rotates in the above direction because the center of gravity of the locking member R ₂ (R ₁ ) suspended from the link member L ₂ (L ₁ ) This is due to the presence of the detachment prevention device E ₂ (E ₁ ) on the side of the connection pin 24 that constitutes the link member L ₂ (L ₁ ).

FIG. 11 is a perspective view of the “open state” of the wing plate pressing device A ₂ of the _second embodiment, and FIG. 12 is a perspective view of the pressing member D ₂ to which the rotation preventing torsion bar 41 is mounted as viewed from the back side. FIG. 13 is a side view of the wing plate presser A ₂ immediately before the final inversion position of the tilt plate 73, and FIG. 14 is a side view of the wing plate presser A ₂ in the final inversion position of the tilt plate 73. FIG. 15 is a side view of the final inversion position of the wing plate presser A ₂ without the rotation preventing torsion bar 41. The wing plate presser A ₂ of the _second embodiment is different from the presser A _{1 of the} first embodiment described above in that the lock member R ₂ is engaged in the opening 4 of the presser member D ₂ when the tilt plate 73 is reversed. A structure provided with a rotation prevention torsion bar (rotation prevention member) 41 that prevents the portion of the pawl 13 from entering and prevents the lock member R ₂ from rotating significantly with respect to the presser member D ₂ . Since the other configurations are substantially the same or the same, the same or the same parts are denoted by the same reference numerals, and only the configuration and the operation of the rotation prevention torsion bar (rotation prevention member) 41 are provided. explain.

As shown in FIGS. 10 and 11, the presser member D ₂ is formed by connecting the upper ends of a pair of rail members 42 having a U-shaped cross section opened to the front side at a predetermined interval in the width direction by the presser 8. Thus, the opening 4 is formed between the pair of left and right rail members 42. Hinge member H ₂ is connected via a fulcrum pin 43 inwardly bent plate portion 42a of the rail member 42 of the pressing member D _2, is connected the lock member R ₂ to the pressing member D ₂ through the dying member H ₂ Yes. As shown in FIG. 12, a torsion bar support bracket 44 is integrally attached to the back surface of the lock member R ₂ , and the central connection portion 41 a of the rotation-preventing torsion bar 41 having a U-shape in front view includes engaging portion 41b for the entire reverse direction was the U-shaped torsion bar 41 is formed, the central connecting portion 41a of the torsion bar 41 is held between the back surface and a torsion bar supporting bracket 44 of the pressing member D ₂ is, the hooking piece 45 formed on the pressing member D _2, engaging portion 41b formed in a central portion of the central coupling portion 41a of the rotation preventing torsion bar 41 is hooked. A pair of leg portions 41c which constitutes a rotation preventing torsion bar 41 is accommodated in each rail member 42 of the pressing member D ₂ respectively, the portion corresponding to the tip portion of the leg portion 41c of each rail member 42 covers Covered with a plate 46. Other configurations are the same as those of the wing plate presser A _{1 of the} first embodiment.

For this reason, in the wing plate presser A ₂ , a rotation prevention torsion bar that prevents the portion of the locking claw 13 at the tip of the presser member D ₂ from entering the opening 4 of the lock member R ₂ when the tilt plate 73 is reversed. Since (rotation preventing member) 41 is provided, as shown in FIGS. 13 and 14, each leg portion 41 c of the torsion bar 41 is accommodated in each rail member 42 constituting the presser member D ₂ . When the tilting plate 73 is reversed, the locking claw 13 at the tip of the locking member R ₂ is prevented from entering the opening 4 of the pressing member D ₂ . As a result, in the immediately preceding final turning position of the tilt plate 73, the locking member R ₂ with respect to the pressing member D ₂ holding the suspended state to the fulcrum shaft 10 is in a state of maintaining a substantially parallel (absolute space the If the reference, the locking member R ₂ is substantially vertical). Therefore, if they do not have the rotation preventing torsion bar (rotation preventing member) 41, preventing the locking member of equipment G and the locking member R ₂ present on the inverting locus of R ₂ that collides The devices G are protected. Moreover, the elasticity of the torsion bar 41, in the reverse when the tilt plate 73, when the locking member R ₂ with respect to the pressing member D ₂ is rotated, the locking member R ₂ that collides with the pressing member D ₂ Therefore, the wing plate presser A ₂ is also protected.

The pressing member D ₃ has substantially the same configuration as the pressing member D _{2 of the} second embodiment, and the hinge member L ₃ is connected to the inner bent plate portion 42 a of each rail member 42 of the pressing member D ₃ via a pair of fulcrum pins 43. ₃ is connected, and the lock member R ₃ is connected to the pressing member D ₃ via the hinge member L ₃ . A connection bracket 52 is integrally attached to the back surface of the lock member R ₃ , and a rotation prevention spring 51 in which a spring wire is bent is attached to an upper end portion of the connection bracket 52 so as to protrude upward. The anti-rotation spring 51 has a contact portion 51a formed by bending the central portion of the spring wire into a mountain shape, and parallel portions 51b and 51c having different lengths are continuously formed on the contact portion 51a. The base end portions of the portions 51b and 51c are bent inward to form a support portion 51d, and the parallel portions 51b and 51c are disposed outside the both side surfaces of the upper end portion of the connection bracket 52, and the support portions 51d are interposed therebetween. An anti-rotation spring 51 is attached to the upper end of the connection bracket 52.

The anti-rotation spring 51 is formed by bending a spring wire. Since the lengths of the parallel portions 51b and 51c are different, the tip of the anti-rotation spring 51 is reversed when the tilt plate 73 is reversed. after the contact portion 51a is in contact with the pressing surface 1 of the pressing member D ₃ is rotation prevention spring 51, by being torsionally deformed without being rotated around the respective support portions 51d, The distal end portion of the lock member R ₃ is prevented from entering the opening 4 of the presser member D ₃ . In the wing plate presser A _{3 according to the} third embodiment, the lock member R ₃ protrudes to the back side of the loading platform and collides with various devices G when the tilt plate 73 is reversed by the rotation prevention spring 51 having a very simple configuration. And the collision of the lock member R _{3 with} the presser member D ₃ can be mitigated by the elasticity of the rotation preventing spring 51.

In the second and third embodiments, when the tilt plate 73 is reversed, the leading end of the lock member R ₂ (R ₃ ) protrudes toward the tilt plate 73 through the opening 4 of the presser member D ₂ (D ₃ ). The anti-rotation member 41 includes the anti-rotation torsion bar 41 and the anti-rotation spring 51. The anti-rotation member includes a lock member and a holding member when the tilt plate 73 is reversed. It is necessary to be able to prevent the position substantially parallel to be greatly exceeded, and any configuration may be used as long as this condition is satisfied.
