　締結具１３０は、車体フレーム８のサイドレール１８１と支持フレーム６のサイドレール１６１とを上下から挟んで支持する一対の挟持部としての挟持パッド１３２と、一対の挟持パッド１３２間の距離を変化させることにより、一対の挟持パッド１３２による車体フレーム８及び支持フレーム６に対する押圧力を調整する調整部としての調整ユニット１３４と、を備える。以下、一対の挟持パッド１３２のうち、支持フレーム６側の挟持パッド１３２を上側パッド１３２Ｕと称し、車体フレーム８側の挟持パッド１３２を下側パッド１３２Ｌと称する。 The fastener 130 changes the distance between the pair of sandwiching pads 132 and the pair of sandwiching pads 132 as a pair of sandwiching portions that sandwich and support the side rails 181 of the vehicle body frame 8 and the side rails 161 of the support frame 6 vertically. Thus, an adjusting unit 134 is provided as an adjusting unit that adjusts the pressing force of the pair of sandwiching pads 132 against the vehicle body frame 8 and the support frame 6. Hereinafter, among the pair of sandwiching pads 132, the sandwiching pad 132 on the support frame 6 side is referred to as the upper pad 132U, and the sandwiching pad 132 on the vehicle body frame 8 side is referred to as the lower pad 132L.
　調整ユニット１３４は、上下端部にめねじが形成された左右一対の軸部としてのスタッドボルト１３１と、スタッドボルト１３１のめねじに螺合されるおねじが形成された複数のナット１３３と、を有する。左右一対のスタッドボルト１３１は、車体フレーム８及び支持フレーム６のサイドレール１８１，１６１を挟むように、サイドレール１８１，１６１の左右に配置される。 The adjustment unit 134 includes a stud bolt 131 as a pair of left and right shaft parts having internal threads formed at upper and lower ends, and a plurality of nuts 133 with external threads formed to be engaged with the internal threads of the stud bolt 131. Have. The pair of left and right stud bolts 131 are disposed on the left and right of the side rails 181 and 161 so as to sandwich the side rails 181 and 161 of the vehicle body frame 8 and the support frame 6.
　スタッドボルト１３１の上端部は、上側パッド１３２Ｕの貫通孔に挿通され、ナット１３３が螺合される。スタッドボルト１３１の下端部は、下側パッド１３２Ｌの貫通孔に挿通され、ナット１３３が螺合される。このため、ナット１３３の締め付け量を調整することにより、一対の挟持パッド１３２間の距離を調整することができる。すなわち、車体フレーム８と支持フレーム６とを一対の挟持パッド１３２で挟んだ状態でナット１３３の締め付け量を調整することにより、一対の挟持パッド１３２による挟持力（フレームに対する押圧力）を調整することができる。 The upper end portion of the stud bolt 131 is inserted into the through hole of the upper pad 132U, and the nut 133 is screwed. The lower end portion of the stud bolt 131 is inserted into the through hole of the lower pad 132L, and the nut 133 is screwed. For this reason, by adjusting the tightening amount of the nut 133, the distance between the pair of holding pads 132 can be adjusted. That is, by adjusting the tightening amount of the nut 133 in a state where the vehicle body frame 8 and the support frame 6 are held between the pair of holding pads 132, the holding force (pressure on the frame) by the pair of holding pads 132 is adjusted. Can.
　固定部１２０は、締結具１３０と係合可能であり、平板１２１と一対の円柱１２２とを有する。平板１２１は矩形平板状であり、円柱１２２は円柱状である。一対の円柱１２２は、平板１２１の前後端部に溶接により固着される。平板１２１は、支持フレーム６のサイドレール１６１の上面６ａに載置され、溶接により支持フレーム６に固着される。 The fixing portion 120 is engageable with the fastener 130 and has a flat plate 121 and a pair of cylinders 122. The flat plate 121 has a rectangular flat plate shape, and the cylinder 122 has a cylindrical shape. The pair of cylinders 122 is fixed to the front and rear end portions of the flat plate 121 by welding. The flat plate 121 is placed on the upper surface 6 a of the side rail 161 of the support frame 6 and fixed to the support frame 6 by welding.
　図５Ａに示すように、固定部１２０には、平板１２１と一対の円柱１２２とにより、左右側部及び上部が開放された凹部１２９が形成される。平板１２１の上面が凹部１２９の底面を形成し、一対の円柱１２２の対向する内側の円周面が凹部１２９の側面を形成する。 As shown to FIG. 5A, the recessed part 129 by which the left-right side part and upper part were open | released is formed in the fixing | fixed part 120 by the flat plate 121 and a pair of circular cylinder 122. As shown in FIG. The upper surface of the flat plate 121 forms the bottom of the recess 129, and the opposing inner circumferential surfaces of the pair of cylinders 122 form the side of the recess 129.
　凹部１２９の内寸法Ｗｉ、すなわち一対の円柱１２２間の最短距離は、上側パッド１３２Ｕの前後方向寸法Ｗｐと同一か僅かに大きい寸法（公差を加味した寸法）に設定される。 The inner dimension Wi of the recess 129, that is, the shortest distance between the pair of cylinders 122, is set to a dimension (a dimension taking into account a tolerance) the same as or slightly larger than the longitudinal dimension Wp of the upper pad 132U.
　図５Ｂに示すように、固定部１２０に形成された凹部１２９には、上側パッド１３２Ｕが嵌入する。つまり、上側パッド１３２Ｕの下端部は、固定部１２０の凹部１２９に嵌入する嵌入部として機能する。締結具１３０は、固定部１２０の凹部１２９の前側の側部を構成する円柱１２２と上側パッド１３２Ｕの前端面とが接触することにより、支持フレーム６に対する前方への移動が規制される。締結具１３０は、凹部１２９の後側の側部を構成する円柱１２２と上側パッド１３２Ｕの後端面とが接触することにより、支持フレーム６に対する後方への移動が規制される。 As shown in FIG. 5B, the upper pad 132U is fitted into the recess 129 formed in the fixing portion 120. That is, the lower end portion of the upper pad 132U functions as a fitting portion to be fitted into the concave portion 129 of the fixing portion 120. The forward movement of the support frame 6 with respect to the support frame 6 is restricted by the contact between the circular column 122 forming the front side of the recess 129 of the fixing portion 120 and the front end surface of the upper pad 132U. The movement of the fastener 130 in the rearward direction with respect to the support frame 6 is restricted by the contact between the cylinder 122 forming the rear side of the recess 129 and the rear end surface of the upper pad 132U.
　このように、締結具１３０は、固定部１２０の凹部１２９と上側パッド１３２Ｕとが係合することにより、支持フレーム６に対する前後方向への移動が規制される。換言すれば、締結具１３０に対する支持フレーム６の前後方向への移動が規制される。つまり、締結具１３０によって、車体フレーム８に対する支持フレーム６の前後方向への移動が規制される。 Thus, the movement of the fastener 130 in the front-rear direction with respect to the support frame 6 is restricted by the engagement of the concave portion 129 of the fixing portion 120 and the upper pad 132U. In other words, movement of the support frame 6 in the front-rear direction with respect to the fastener 130 is restricted. That is, the movement of the support frame 6 in the front-rear direction with respect to the vehicle body frame 8 is restricted by the fastener 130.
　固定部１２０に凹部１２９を設け、この凹部１２９に上側パッド１３２Ｕを嵌入させる簡素な構成で、支持フレーム６に対する締結具１３０の前後方向移動を規制することができる。支持フレーム６自体に凹部を形成せず、支持フレーム６とは別部材である固定部１２０に凹部１２９を形成するようにしたので、支持フレーム６の強度が低下することはない。 The simple structure in which the recessed portion 129 is provided in the fixing portion 120 and the upper pad 132U is fitted into the recessed portion 129 can restrict the longitudinal movement of the fastener 130 with respect to the support frame 6. Since the recess is not formed in the support frame 6 itself, and the recess 129 is formed in the fixing portion 120 which is a separate member from the support frame 6, the strength of the support frame 6 is not reduced.
　図６に示すように、左右一対のスタッドボルト１３１間の最短距離であるボルト間寸法Ｗｂは、固定部１２０の平板１２１の左右幅寸法Ｗｆと同一か僅かに大きい寸法（公差を加味した寸法）に設定される。 As shown in FIG. 6, the inter-bolt dimension Wb, which is the shortest distance between the pair of left and right stud bolts 131, is equal to or slightly larger than the left-right width dimension Wf of the flat plate 121 of the fixed portion 120 (dimension in consideration of tolerance) Set to
　左右一対のスタッドボルト１３１は、固定部１２０の平板１２１の左右に配置される。換言すれば、左右一対のスタッドボルト１３１間に、固定部１２０の平板１２１が配置される。締結具１３０は、平板１２１の右端面１２１Ｒと右側のスタッドボルト１３１とが接触することにより、支持フレーム６に対する左方への移動が規制される。締結具１３０は、平板１２１の左端面１２１Ｌと左側のスタッドボルト１３１とが接触することにより、支持フレーム６に対する右方への移動が規制される。 The pair of left and right stud bolts 131 are disposed on the left and right of the flat plate 121 of the fixed portion 120. In other words, the flat plate 121 of the fixing portion 120 is disposed between the pair of left and right stud bolts 131. Movement of the fastener 130 in the left direction with respect to the support frame 6 is restricted by contact between the right end surface 121R of the flat plate 121 and the stud bolt 131 on the right side. By the left end surface 121L of the flat plate 121 and the left stud bolt 131 coming into contact with each other, the movement of the fastener 130 to the right with respect to the support frame 6 is restricted.
　このように、締結具１３０は、平板１２１の左右端部と左右一対のスタッドボルト１３１とが係合することにより、支持フレーム６に対する左右方向への移動が規制される。換言すれば、締結具１３０に対する支持フレーム６の左右方向への移動が規制される。つまり、締結具１３０によって、車体フレーム８に対する支持フレーム６の左右方向への移動が規制される。 In this manner, the left and right end portions of the flat plate 121 and the pair of left and right stud bolts 131 engage with each other, whereby the movement of the fastener 130 in the left-right direction with respect to the support frame 6 is restricted. In other words, the lateral movement of the support frame 6 with respect to the fastener 130 is restricted. That is, the movement of the support frame 6 relative to the vehicle body frame 8 in the left-right direction is restricted by the fastener 130.
　固定部１２０の平板１２１の左右端部に左右一対のスタッドボルト１３１を係合させる簡素な構成で、支持フレーム６に対する締結具１３０の左右方向移動を規制することができる。 The simple configuration in which the left and right stud bolts 131 are engaged with the left and right end portions of the flat plate 121 of the fixing portion 120 can restrict the lateral movement of the fastener 130 with respect to the support frame 6.
　支持フレーム６は、サイドレール１６１にクロスメンバ１６２が溶接された溶接構造物である。したがって、支持フレーム６を製造する過程で、固定部１２０を支持フレーム６に溶接しておくことができる。このため、支持フレーム６を車体フレーム８に組み付ける工程において、溶接作業が発生することがない。 The support frame 6 is a welded structure in which the cross member 162 is welded to the side rail 161. Therefore, in the process of manufacturing the support frame 6, the fixing portion 120 can be welded to the support frame 6. Therefore, no welding operation occurs in the process of assembling the support frame 6 to the vehicle body frame 8.
　支持フレーム６には、車体フレーム８に組み付けられる工程の前に、油圧機器、燃料装置、電装品等が予め取り付けられている。このため、車体フレーム８に支持フレーム６を組み付ける際に溶接作業を行うと、溶接作業時に発生する溶接スパッタが周囲に配置される油圧機器（ポンプ、ホース、バルブ等）、燃料装置（燃料タンク、燃料ホース等）、電装品（コントローラ、ケーブル等）に付着するおそれがある。このため、組み付け工程において溶接作業を行う場合、周辺機器に対して十分な養生を施す必要があり、作業が煩雑になる。 A hydraulic device, a fuel device, an electrical component and the like are attached to the support frame 6 in advance before the process of being assembled to the vehicle body frame 8. Therefore, if welding work is performed when assembling the support frame 6 to the vehicle body frame 8, hydraulic equipment (pumps, hoses, valves, etc.) around which weld spatter generated during welding work is disposed, fuel device (fuel tank, It may adhere to fuel hoses, etc., electrical components (controllers, cables, etc.). For this reason, when performing a welding operation in the assembly process, it is necessary to sufficiently cure the peripheral equipment, and the operation becomes complicated.
　これに対して、本実施形態では、上述のとおり、車体フレーム８に支持フレーム６を組み付ける際、溶接作業を必要としない。このため、溶接スパッタの付着に起因した品質不良が発生するおそれがなく、養生も不要である。つまり、本実施形態によれば、車体フレーム８に対する支持フレーム６の組立作業性を向上することができ、かつ、品質の高いミキサ車１００を提供することができる。 On the other hand, in the present embodiment, when assembling the support frame 6 to the vehicle body frame 8 as described above, no welding operation is required. For this reason, there is no possibility that the quality defect resulting from adhesion of a welding spatter will occur, and curing is also unnecessary. That is, according to this embodiment, the assembly workability of the support frame 6 with respect to the vehicle body frame 8 can be improved, and the mixer car 100 with high quality can be provided.
　また、予め固定部１２０が支持フレーム６に溶接されているので、車体フレーム８に支持フレーム６を組み付ける工程において、作業者は、締結具１３０の位置決めを容易に行うことができる。 Further, since the fixing portion 120 is welded to the support frame 6 in advance, the worker can easily position the fastener 130 in the process of assembling the support frame 6 to the vehicle body frame 8.
　上述した第１実施形態によれば、次の作用効果を奏する。 According to the above-described first embodiment, the following effects can be obtained.
　（１）固定部１２０に締結具１３０が係合することにより、支持フレーム６に対する締結具１３０の前後左右方向への移動が規制される。換言すれば、締結具１３０に対する支持フレーム６の前後左右方向への移動が規制される。つまり、本実施形態によれば、車両の発進、停止に伴う衝撃、及び車両の走行中の振動等に起因する車体フレーム８に対する支持フレーム６の位置ずれを防止できる締結装置１１０及びこれを備えるミキサ車１００を提供することができる。 (1) The fastener 130 is engaged with the fixing portion 120 to restrict movement of the fastener 130 relative to the support frame 6 in the front-rear and left-right directions. In other words, the movement of the support frame 6 in the front-rear and left-right directions with respect to the fastener 130 is restricted. That is, according to the present embodiment, the fastening device 110 capable of preventing the positional deviation of the support frame 6 with respect to the vehicle body frame 8 caused by the shock accompanying the start and stop of the vehicle and the vibration during traveling of the vehicle A car 100 can be provided.
　＜第１実施形態の変形例＞
　上記第１実施形態では、固定部１２０に凹部１２９が一つ設けられる例について説明したが、本発明はこれに限定されない。固定部１２０に複数の凹部を設け、上側パッド１３２Ｕに複数の凸部を設けてもよい。たとえば、上記第１実施形態を次のように変形してもよい。 Modification of First Embodiment
Although the said 1st Embodiment demonstrated the example in which the one recessed part 129 is provided in the fixing | fixed part 120, this invention is not limited to this. The fixing portion 120 may be provided with a plurality of concave portions, and the upper pad 132U may be provided with a plurality of convex portions. For example, the first embodiment may be modified as follows.
　本変形例では、一対の円柱１２２を平板１２１に取り付けることに代えて、図７Ａ及び図７Ｂに示すように、固定部２２０の平板２２１に凹凸部２２９が形成される。凹凸部２２９は、山部（凸部）２２９ａと谷部（凹部）２２９ｂとが交互に配置された波状に形成される。 In the present modification, instead of attaching the pair of cylinders 122 to the flat plate 121, as shown in FIGS. 7A and 7B, the uneven portion 229 is formed on the flat plate 221 of the fixing portion 220. The uneven portion 229 is formed in a wave shape in which peak portions (convex portions) 229 a and valley portions (concave portions) 229 b are alternately arranged.
　上側パッド２３２Ｕは、直方体部材に係合板２３８が固着されてなる。係合板２３８には、固定部２２０の凹凸部２２９に係合する凹凸部２３９が形成される。凹凸部２３９は、山部（凸部）２３９ａと谷部（凹部）２３９ｂとが交互に配置された波状に形成される。このような変形例によれば、複数の凹部（２２９ｂ，２３９ｂ）と凸部（２２９ａ，２３９ａ）とが嵌合することにより、上記第１実施形態と同様、締結具２３０と支持フレーム６の相対的な前後方向の移動が規制される。 In the upper pad 232U, an engagement plate 238 is fixed to a rectangular parallelepiped member. The engagement plate 238 is formed with an uneven portion 239 engaged with the uneven portion 229 of the fixed portion 220. The uneven portion 239 is formed in a wave shape in which peak portions (convex portions) 239 a and valley portions (concave portions) 239 b are alternately arranged. According to such a modification, by fitting the plurality of concave portions (229b, 239b) and the convex portions (229a, 239a), the relative position between the fastener 230 and the support frame 6 is the same as in the first embodiment. Forward and backward movement is restricted.
　＜第２実施形態＞
　図８を参照して、本発明の第２実施形態に係る締結装置３１０について説明する。以下では、上記第１実施形態と異なる点を中心に説明し、図中、上記第１実施形態で説明した構成と同一の構成または相当する構成には同一の符号を付して説明を省略する。 Second Embodiment
A fastening device 310 according to a second embodiment of the present invention will be described with reference to FIG. In the following description, differences from the first embodiment are mainly described, and in the figure, the same reference numerals are given to the same or corresponding components as the components described in the first embodiment, and the description is omitted. .
　第１実施形態では、一つの固定部１２０に対して一つの凹部１２９が設けられる例について説明した。これに対して、第２実施形態では、一つの固定部３２０に対して複数の凹部３２９が設けられる。 In the first embodiment, an example in which one recess 129 is provided for one fixing portion 120 has been described. On the other hand, in the second embodiment, a plurality of recesses 329 are provided for one fixing portion 320.
　第１実施形態では、車体フレーム８に支持フレーム６を組み付ける作業の前段階において、固定部１２０が支持フレーム６に予め溶接されていた。このため、スタッドボルト１３１は、固定部１２０により所定の位置に位置決めされる。しかしながら、ミキサ車１００は、仕様によって車体フレーム８の形状が異なる場合がある。 In the first embodiment, the fixing portion 120 is pre-welded to the support frame 6 in the front stage of the work of assembling the support frame 6 to the vehicle body frame 8. Therefore, the stud bolt 131 is positioned at a predetermined position by the fixing portion 120. However, the shape of the vehicle body frame 8 may differ depending on the specifications of the mixer vehicle 100.
　第１実施形態では、スタッドボルト１３１が配置される位置にスタッドボルト１３１に干渉してしまう障害物（たとえば、ボルト、リブ等）が存在する場合、固定部１２０の位置を変更する必要が生じる。この場合、固定部１２０を支持フレーム６から取り外し、障害物を回避してスタッドボルト１３１を配置できる位置に固定部１２０を再度溶接しなければならない。 In the first embodiment, when there is an obstacle (for example, a bolt, a rib or the like) that interferes with the stud bolt 131 at the position where the stud bolt 131 is disposed, the position of the fixing portion 120 needs to be changed. In this case, the fixing portion 120 must be removed from the support frame 6, and the fixing portion 120 must be welded again at a position where the stud bolt 131 can be disposed while avoiding an obstacle.
　本第２実施形態の締結装置３１０では、上記問題点を解決するために、固定部３２０に、締結具１３０と係合可能な凹部３２９が前後方向に複数並んで設けられる。 In the fastening device 310 of the second embodiment, in order to solve the above-mentioned problems, a plurality of recessed portions 329 engageable with the fastener 130 are provided in the fixing portion 320 in the front-rear direction.
　締結具１３０は、複数の凹部３２９（３２９ａ，３２９ｂ，３２９ｃ，３２９ｄ）のうちの一つに上側パッド１３２Ｕが係合することにより、支持フレーム６に対する前後方向への移動が規制される。 Movement of the fastener 130 in the front-rear direction with respect to the support frame 6 is restricted by the upper pad 132U being engaged with one of the plurality of recesses 329 (329a, 329b, 329c, 329d).
　本第２実施形態では、一枚の矩形状の平板３２１に５本の円柱１２２が前後方向に等間隔で溶接されている。各円柱１２２は、左右方向に延在するように配置される。隣り合う円柱１２２と、平板３２１とにより凹部３２９が形成される。 In the second embodiment, five cylinders 122 are welded to the one rectangular flat plate 321 at regular intervals in the front-rear direction. Each cylinder 122 is arranged to extend in the left-right direction. The concave portion 329 is formed by the adjacent cylinders 122 and the flat plate 321.
　車体フレーム８には、障害物３９０が設けられており、凹部３２９ｄに上側パッド１３２Ｕを嵌合させた場合、スタッドボルト１３１と障害物３９０とが干渉してしまう。このため、凹部３２９ａに上側パッド１３２Ｕを嵌合させることにより、スタッドボルト１３１と障害物３９０との干渉を回避することができる。 The body frame 8 is provided with an obstacle 390, and when the upper pad 132U is fitted in the recess 329d, the stud bolt 131 and the obstacle 390 interfere with each other. Therefore, by fitting the upper pad 132U to the recess 329a, interference between the stud bolt 131 and the obstacle 390 can be avoided.
　このような第２実施形態によれば、第１実施形態の作用効果に加え、次の作用効果を奏する。 According to the second embodiment, in addition to the effects of the first embodiment, the following effects are achieved.
　（２）固定部３２０に対する締結具１３０の係合位置を簡単に調整することができ、固定部３２０の取り外し作業及び再溶接作業が発生することを防止できる。つまり、本第２実施形態によれば、種々の仕様の車体フレーム８に対して適合可能な汎用性の高い締結装置３１０を提供することができる。 (2) The engagement position of the fastener 130 with respect to the fixed portion 320 can be easily adjusted, and the occurrence of the removal operation and the re-welding operation of the fixed portion 320 can be prevented. That is, according to the second embodiment, it is possible to provide a highly versatile fastening device 310 that can be adapted to the vehicle body frame 8 of various specifications.
　＜第２実施形態の変形例＞
　上記第２実施形態では、複数の凹部３２９のうちの一つに上側パッド１３２Ｕの下側部分が係合することにより、支持フレーム６に対する締結具１３０の前後方向への移動が規制される例について説明したが、本発明はこれに限定されない。複数の凹部３２９のうちの少なくとも一つに締結具１３０が係合すればよい。たとえば、上記第２実施形態を次のように変形してもよい。 Modification of Second Embodiment
In the second embodiment, the lower portion of the upper pad 132U is engaged with one of the plurality of concave portions 329, thereby restricting the movement of the fastener 130 with respect to the support frame 6 in the front-rear direction. Although described, the present invention is not limited thereto. The fastener 130 may be engaged with at least one of the plurality of recesses 329. For example, the second embodiment may be modified as follows.
　本変形例では、複数の円柱１２２を平板３２１に取り付けることに代えて、図９Ａに示すように、固定部４２０の平板４２１に凹凸部４２９が形成される。凹凸部４２９は、山部（凸部）４２９ａと谷部（凹部）４２９ｂとが交互に配置される。 In the present modification, instead of attaching the plurality of cylinders 122 to the flat plate 321, as shown in FIG. 9A, the uneven portion 429 is formed on the flat plate 421 of the fixed portion 420. In the uneven portion 429, peak portions (convex portions) 429a and valley portions (concave portions) 429b are alternately disposed.
　上側パッド４３２Ｕは、直方体部材に係合板４３８が固着されてなる。係合板４３８には、固定部４２０の凹凸部４２９に係合する凹凸部４３９が形成される。凹凸部４３９は、山部（凸部）４３９ａと谷部（凹部）４３９ｂとが交互に配置される。 In the upper pad 432U, an engagement plate 438 is fixed to a rectangular parallelepiped member. The engagement plate 438 is formed with an uneven portion 439 engaged with the uneven portion 429 of the fixed portion 420. In the uneven portion 439, peak portions (convex portions) 439a and valley portions (concave portions) 439b are alternately disposed.
　固定部４２０には５つの谷部４２９ｂが形成されるのに対し、係合板４３８には、谷部４２９ｂに係合可能な山部４３９ａが３つ形成される。このような変形例によれば、図９Ｂ及び図９Ｃに示すように、５つの谷部４２９ｂのうちの３つの谷部４２９ｂと、３つの山部４３９ａと、が嵌合することにより、上記第２実施形態と同様、締結具４３０と支持フレーム６の相対的な前後方向の移動が規制される。 While five valleys 429 b are formed in the fixing portion 420, three ridges 439 a engageable with the valleys 429 b are formed in the engagement plate 438. According to such a modification, as shown in FIG. 9B and FIG. 9C, the third valley portion 429b of the five valley portions 429b and the three peak portions 439a are engaged with each other, thereby Similar to the second embodiment, relative longitudinal movement of the fastener 430 and the support frame 6 is restricted.
　＜第３実施形態＞
　図１０を参照して、本発明の第３実施形態に係る締結装置５１０について説明する。以下では、上記第２実施形態と異なる点を中心に説明し、図中、上記第２実施形態で説明した構成と同一の構成または相当する構成には同一の符号を付して説明を省略する。なお、第３実施形態では、第２実施形態で説明した円柱１２２が設けられず、平板５２１が固定部５２０を構成する。 Third Embodiment
A fastening device 510 according to a third embodiment of the present invention will be described with reference to FIG. In the following description, differences from the second embodiment are mainly described, and in the figure, the same components as or corresponding components to the components described in the second embodiment are given the same reference numerals, and the description thereof is omitted. . In the third embodiment, the cylinder 122 described in the second embodiment is not provided, and the flat plate 521 constitutes the fixing portion 520.
　上記第２実施形態では、固定部３２０の平板３２１の左右端部と左右一対のスタッドボルト１３１とが接触することにより、支持フレーム６に対する締結具１３０の左右方向への移動が規制される。これに対して、本第３実施形態では、平板５２１の左右端部と、左右一対のスタッドボルト１３１とは接触しない。 In the second embodiment, when the left and right end portions of the flat plate 321 of the fixing portion 320 and the pair of left and right stud bolts 131 contact, the movement of the fastener 130 relative to the support frame 6 in the left and right direction is restricted.
