In particular, the lower stay 13R is shown in the figure, but the lower stay 13L is similarly configured symmetrically. The lower stay 13 is formed by bending a single metal plate, and has a right side surface 13b, a left side surface 13c, and an upper surface 13d, and is formed in a U-shaped cross section. Further, a bent portion 53 extending from the upper surface 13d and bent downward is formed at the front portion, and the front surface of the bent portion 53 is a front end surface 13a of the lower stay 13 that comes into contact with the front leg 12R. . The rear portion of the right side surface 13b of the lower stay 13 serves as an opposing surface 13ba that faces and abuts the side plate 11R. The bent portion 53 may be formed to extend from the right side surface 13b or the left side surface 13c.

屈曲部53には、締結用穴36が2つ設けられる。対向面13baには、締結用穴57、58、59が設けられる。左側面13cには、締結用穴57、58、59に対応する位置に、ネジ取り付け用の大穴54、55、及び切欠部56が形成されている。図2に示すように、下側ステイ13の前端面13aは、前脚12Rの下部12Raの後面に当接し、該下部12Raに締結用穴36を介してネジ37で螺着される。また、下側ステイ13の対向面13baは、側板11Rの下部11Raの内側面(左側面)に当接し、該下部11Raに締結用穴57、58、59を介してネジ38で螺着される。その際、上記大穴54、55及び切欠部56は、ネジ38を工具で支持体ユニットSUの内側から螺合操作するための作業用逃げ部として機能する。なお、締結用穴36、57、58、59は、必ずしも穴でなくてもよく、切欠部であってもよい。   The bending portion 53 is provided with two fastening holes 36. Fastening holes 57, 58, and 59 are provided in the facing surface 13ba. On the left side surface 13c, screw-attached large holes 54, 55 and a notch 56 are formed at positions corresponding to the fastening holes 57, 58, 59. As shown in FIG. 2, the front end surface 13a of the lower stay 13 abuts on the rear surface of the lower portion 12Ra of the front leg 12R, and is screwed to the lower portion 12Ra with a screw 37 through a fastening hole 36. Further, the facing surface 13ba of the lower stay 13 abuts on the inner surface (left side surface) of the lower portion 11Ra of the side plate 11R, and is screwed to the lower portion 11Ra with a screw 38 through fastening holes 57, 58, 59. . At that time, the large holes 54 and 55 and the cutout portion 56 function as a working escape portion for screwing the screw 38 from the inside of the support unit SU with a tool. The fastening holes 36, 57, 58, 59 are not necessarily holes and may be notches.

このようにして、側板11R、前脚12R、下側ステイ13R及び上側ステイ20で側面視ロ字状の右側の枠体が完成する。同様に、左右対称の側板11L、前脚12L、下側ステイ13L及び上側ステイ20で、側面視ロ字状の枠体が完成する。そして、側板11Rの後部と側板11Lの後部とを、背面板14で連結固定することで(図2、図3参照)、それ自体で剛性の高い支持体ユニットSUの基本部分が完成する。   In this way, the right side frame body having a square shape in a side view is completed by the side plate 11R, the front leg 12R, the lower stay 13R, and the upper stay 20. Similarly, a frame body having a square shape in side view is completed with the laterally symmetrical side plates 11L, the front legs 12L, the lower stay 13L, and the upper stay 20.

図2、図6に示すように、山板41の内側には、屋根ユニットRUの前板部62(後述)と当接する当接部材50、51と、固定部材43とが固定されている。この固定部材43には、図6に示すように、屋根ユニットRUを取り付けるための屋根ユニット取り付け金具44が取り付けられている。屋根ユニット取り付け金具44については後述する。   As shown in FIGS. 2 and 6, abutting members 50 and 51 that abut a front plate portion 62 (described later) of the roof unit RU and a fixing member 43 are fixed to the inner side of the pile 41. As shown in FIG. 6, a roof unit mounting bracket 44 for mounting the roof unit RU is attached to the fixing member 43. The roof unit mounting bracket 44 will be described later.

図2、図3、図5(a)、(b)に示すように、受け部材30は、金属で一体に形成され、固着部31と、固着部31に対して段差を有する受け部32とで成る。固着部31がネジ35で側板11Rの内側面11Rcに螺着固定され、受け部32が、内側面11Rcから離間している。図3、図5(a)、(b)に示すように、受け部32には、2つの側面視U字状の受け口33(33A、33B)が形成され、各受け口33A、33Bには、それぞれ、上方に拡開した斜面で成るガイド部34(34A、34B)が連設されている。   As shown in FIGS. 2, 3, 5 (a) and 5 (b), the receiving member 30 is integrally formed of metal, and includes a fixing portion 31 and a receiving portion 32 having a step with respect to the fixing portion 31. It consists of The fixing portion 31 is screwed and fixed to the inner side surface 11Rc of the side plate 11R with a screw 35, and the receiving portion 32 is separated from the inner side surface 11Rc. As shown in FIGS. 3, 5A, and 5B, the receiving portion 32 is formed with two U-shaped receiving ports 33 (33A, 33B) in side view, The guide portions 34 (34A, 34B) each having a slope that spreads upward are continuously provided.

一方、鉤状部材45A、45Bは同様に構成され、受け口33A、33Bに対応して、山板41の側面41bに、外側方向に向かって突設されている。図5(a)、(b)に示すように、鉤状部材45A、45Bは、それぞれ、円柱状の首部45Aa、45Baと、これら首部45Aa、45Baより大径でボタン状の頭部45Ab、45Bbとから成る。図示はしないが、左側の山板41においても鉤状部材45A、45Bが外側方向に突設されると共に、受け部材30と左右対称の受け部材が側板11Lに設けられる。   On the other hand, the hook-shaped members 45A and 45B are configured in the same manner, and project from the side surface 41b of the mountain plate 41 toward the outer side corresponding to the receiving ports 33A and 33B. As shown in FIGS. 5 (a) and 5 (b), the hook-shaped members 45A and 45B include a columnar neck portion 45Aa and 45Ba, and a button-like head portion 45Ab and 45Bb larger in diameter than the neck portions 45Aa and 45Ba, respectively. It consists of. Although not shown in the drawing, the left side plate 41 is also provided with flange-like members 45A and 45B protruding outward, and a receiving member 30 and a receiving member symmetrical to the left and right are provided on the side plate 11L.

鍵盤楽器本体KBUの支持体ユニットSUへの組み付けは、通常、鍵盤楽器本体KBUに屋根ユニットRUを組み付ける前に行う。鉤状部材45A、45Bの首部45Aa、45Baが受け口33A、33Bに係合するように、目視で見当を付けて鍵盤楽器本体KBUを上方から降ろす。その際、鉤状部材45A、45B及び受け口33A、33Bが見えるので、両者を係合させることが容易である。そして、鉤状部材45A、45Bの首部45Aa、45Baが、ガイド部34A、34Bに案内されて、受け口33A、33Bに確実に嵌入される。これにより、支持体ユニットSUに対する鍵盤楽器本体KBUの前後及び左右方向の仮位置決めが容易になされる。その後、左右の山板41の底部41aを、各3カ所において締結用穴24を介してネジ25で上側ステイ20の上板部22に螺着することで、支持体ユニットSUに対する鍵盤楽器本体KBUの組み付けが完了する。   The keyboard instrument body KBU is usually assembled to the support unit SU before the roof unit RU is assembled to the keyboard instrument body KBU. The keyboard instrument body KBU is lowered from above with visual registration so that the neck portions 45Aa and 45Ba of the hook-like members 45A and 45B engage with the receiving openings 33A and 33B. At this time, since the hook-shaped members 45A and 45B and the receiving ports 33A and 33B are visible, it is easy to engage them. Then, the neck portions 45Aa and 45Ba of the hook-shaped members 45A and 45B are guided by the guide portions 34A and 34B and are securely inserted into the receiving ports 33A and 33B. Thereby, temporary positioning of the keyboard instrument main body KBU with respect to the support unit SU in the front-rear and left-right directions is facilitated. Thereafter, the bottom portions 41a of the left and right mountain plates 41 are screwed to the upper plate portion 22 of the upper stay 20 with screws 25 through the fastening holes 24 at the three locations, so that the keyboard instrument body KBU with respect to the support unit SU. Assembling is completed.

ここで、図5(a)、(b)に示す状態が、仮に、鍵盤楽器本体KBUを支持体ユニットSUに対して左右方向中央の位置に載置した状態であるとして、山板41の側面41bと側板11Rの内側面11Rcとの間隔を「A」、山板41の側面41bに対する背板46の側板11R方向への突出量を「B」、受け部32の内側面(左側面)と側板11Rの内側面11Rcとの距離を「C」、山板41の側面41bと頭部45Ab、45Bbの先端面(右側面)との距離を「D」、山板41の側面41bと頭部45Ab、45Bbの左側面との距離を「E」、受け部32の厚みを「F」としたとき、「D<B<A」という関係、及び「A−C+F<E」という関係が成り立つように、各部の寸法が設定されている。鍵盤楽器本体KBU及び支持体ユニットSUの左側においても同様である。   Here, assuming that the state shown in FIGS. 5A and 5B is a state in which the keyboard instrument main body KBU is placed at the center in the left-right direction with respect to the support unit SU, The distance between 41b and the inner side surface 11Rc of the side plate 11R is "A", the protruding amount of the back plate 46 in the direction of the side plate 11R with respect to the side surface 41b of the pile plate 41 is "B", and the inner side surface (left side surface) of the receiving portion 32 The distance between the inner surface 11Rc of the side plate 11R is “C”, the distance between the side surface 41b of the mountain plate 41 and the tip surfaces (right side surfaces) of the heads 45Ab and 45Bb is “D”, and the side surface 41b of the mountain plate 41 and the head. When the distance from the left side surface of 45Ab and 45Bb is “E” and the thickness of the receiving portion 32 is “F”, the relationship “D <B <A” and the relationship “A−C + F <E” seem to hold. The dimensions of each part are set. The same applies to the left side of the keyboard instrument body KBU and the support unit SU.

このような寸法設定により、鉤状部材45A、45Bを受け口33A、33Bに嵌入する際、背板46を側板11L、11R間に位置させて鍵盤楽器本体KBUを下降させれば、背板46の端面が側板11Rに接触することはあっても、鉤状部材45A、45B頭部45Ab、45Bbが側板11Rの内側面11Rcまたは受け部32と接触することがない。左側においても同様である。よって、組み付け作業時に鍵盤楽器本体KBU及び支持体ユニットSUに傷が付くおそれがほとんどない。   With such dimension setting, when the bowl-shaped members 45A and 45B are inserted into the receiving ports 33A and 33B, the back plate 46 is positioned between the side plates 11L and 11R, and the keyboard instrument body KBU is lowered, the back plate 46 Even if the end surface comes into contact with the side plate 11R, the flange members 45A, 45B head portions 45Ab, 45Bb do not come into contact with the inner side surface 11Rc or the receiving portion 32 of the side plate 11R. The same applies to the left side. Therefore, there is almost no possibility that the keyboard instrument body KBU and the support unit SU are damaged during the assembling work.

ところで、図5(a)に示すように、鍵盤楽器本体KBUにおいて、屋根ユニット取り付け金具44の上面部には、前後方向に長い保持穴44aが形成され、この保持穴44aの前部が、幅広部44aaとなっている。幅広部44aaは、下方に少し延びていて、前斜面44bの上部に開口している。屋根ユニット取り付け金具44の上面部は、後方にいくにつれて低くなっている(図6参照)。この保持穴44aには、後述する係合用ボルト64が係合し、屋根ユニットRUを鍵盤楽器本体KBUに固定する役割の一部を果たす。   By the way, as shown in FIG. 5A, in the keyboard instrument body KBU, a long holding hole 44a is formed in the top and bottom direction of the roof unit mounting bracket 44, and the front part of the holding hole 44a is wide. It is part 44aa. The wide portion 44aa extends slightly downward and opens at the top of the front slope 44b. The upper surface portion of the roof unit mounting bracket 44 is lowered toward the rear (see FIG. 6). Engaging bolts 64 described later are engaged with the holding holes 44a, and play a part of the role of fixing the roof unit RU to the keyboard instrument main body KBU.

[屋根ユニットRUの構成]
図6に示すように、屋根ユニットRUは、屋根板部61と、屋根板部61の前部から斜め前下方に延びる前板部62とが一体に形成され、さらに、前板部62の下部に譜面受け部材63が取り付けられて構成される。屋根板部61において、左右両端部の下面には、スペーサ65を介して、屋根ユニット取り付け金具44に対応する係合用ボルト64が取り付けられている。また、屋根板部61の左右両端部における後部下面には、固着用金具66が取り付けられている。さらに、前板部62の下部の後面には、側面視「く」字状の固定金具67の一片が2つのネジ52で固定され、この固定金具67の他片に、譜面受け部材63の下面がネジ69で固定されている。
[Configuration of roof unit RU]
As shown in FIG. 6, the roof unit RU includes a roof plate portion 61 and a front plate portion 62 that extends diagonally forward and downward from the front portion of the roof plate portion 61, and further, a lower portion of the front plate portion 62. The music score receiving member 63 is attached to the structure. In the roof plate portion 61, engagement bolts 64 corresponding to the roof unit mounting bracket 44 are attached to the lower surfaces of both left and right end portions via spacers 65. Further, fixing metal fittings 66 are attached to the rear lower surfaces of the left and right ends of the roof plate portion 61. Further, one piece of a fixing bracket 67 having a “<” shape in a side view is fixed to the rear surface of the lower portion of the front plate portion 62 with two screws 52, and the other surface of the musical score receiving member 63 is fixed to the other piece of the fixing bracket 67. Is fixed with a screw 69.

上記屋根ユニット取り付け金具44の保持穴44aは、係合用ボルト64の頭部より狭く、保持穴44aの幅広部44aaは、係合用ボルト64の頭部より広くなっている。屋根ユニットRUを鍵盤楽器本体KBUに組み付ける際には、屋根ユニットRUを前方から後方に移動させつつ、係合用ボルト64の頭部を保持穴44aの幅広部44aaに挿入し、山板41上を、屋根ユニットRUを後方にスライドさせる。屋根ユニット取り付け金具44の上面部は、後方にいくにつれて低くなっているので(図6参照)、屋根ユニットRUを後退させるほど、係合用ボルト64と保持穴44aとの係合により、係合用ボルト64の頭部が屋根ユニット取り付け金具44の上面部から下方への付勢力を受け、これにより、屋根ユニットRUが山板41側に押しつけられる。   The holding hole 44 a of the roof unit mounting bracket 44 is narrower than the head of the engaging bolt 64, and the wide portion 44 aa of the holding hole 44 a is wider than the head of the engaging bolt 64. When the roof unit RU is assembled to the keyboard instrument body KBU, the head of the engagement bolt 64 is inserted into the wide portion 44aa of the holding hole 44a while moving the roof unit RU from the front to the rear, Slide the roof unit RU backward. Since the upper surface portion of the roof unit mounting bracket 44 becomes lower as it goes rearward (see FIG. 6), the engagement bolt 64 and the holding hole 44a engage with each other as the roof unit RU is retracted. The 64 heads receive a downward urging force from the upper surface of the roof unit mounting bracket 44, whereby the roof unit RU is pressed against the pile 41 side.

そして、固着用金具66が背板46に当接するまで屋根ユニットRUを後退させる。このとき、屋根ユニットRUの前板部62も、当接部材50、51と当接する。この状態で、固着用金具66を背板46に螺着固定することで、屋根ユニットRUが鍵盤楽器本体KBUに組み付けられる。   Then, the roof unit RU is retracted until the fixing metal fitting 66 comes into contact with the back plate 46. At this time, the front plate portion 62 of the roof unit RU also contacts the contact members 50 and 51. In this state, the fixing unit 66 is screwed and fixed to the back plate 46, whereby the roof unit RU is assembled to the keyboard instrument body KBU.

また、前板部62の下部には、モニタ用スピーカ68(68L、68R)が内装されている(図1、図3も参照)。さらに、屋根板部61の上面には、可倒式の譜面板70が装着されている。   Further, a monitor speaker 68 (68L, 68R) is housed in the lower portion of the front plate portion 62 (see also FIGS. 1 and 3). Furthermore, a folding music score board 70 is mounted on the upper surface of the roof plate portion 61.

かかる構成において、製品としての鍵盤楽器1の納品等のための運搬時には、支持体ユニットSUと鍵盤楽器本体KBUとは組み付けられていない状態で梱包、搬送される。ペダルユニットPKU及びスピーカユニットSPUについても、搬送時には支持体ユニットSUの本体部分とは分離させておくことができるが、これらを組み付けた状態で梱包、搬送してもよい。また、屋根ユニットRUへの譜面板70の装着は、通常、梱包解除後に行われる。さらに、鍵盤楽器本体KBUは、支持体ユニットSUに一旦組み付けた後であっても、修理等の場合において、ネジ25を外して上側ステイ20との締結を解けば、容易に取り外すことができる。   In such a configuration, at the time of transportation for delivery of the keyboard instrument 1 as a product, the support unit SU and the keyboard instrument body KBU are packed and transported without being assembled. The pedal unit PKU and the speaker unit SPU can also be separated from the main body portion of the support unit SU at the time of transport, but may be packed and transported in a state where they are assembled. Moreover, mounting | wearing of the music score board 70 to the roof unit RU is normally performed after packing cancellation | release. Furthermore, even after the keyboard instrument body KBU is once assembled to the support unit SU, it can be easily removed by removing the screw 25 and releasing the fastening with the upper stay 20 in the case of repair or the like.

本実施の形態によれば、鍵盤楽器本体KBUを支持体ユニットSUに組み付ける際、鉤状部材45を受け口33に嵌入することで、鍵盤楽器本体KBUの前後及び左右方向の仮位置決めがなされ、その際、鉤状部材45の首部45Aa、45Baがガイド部34A、34Bに案内されて、受け口33A、33Bに確実に導かれる。それだけでなく、鉤状部材45を受け口33に嵌入するとき、これらの位置関係が目視で確認できるので、位置の見当を付けやすい。従って、指を挟む等の怪我をするおそれが少なく、また、鍵盤楽器本体KBUと支持体ユニットSUとが無用に接触することがないので、両者を傷付けるおそれも少ない。よって、怪我をしたり、鍵盤楽器本体KBUや支持体ユニットSUを傷付けたりすることなく、鍵盤楽器本体KBUを支持体ユニットSUに容易に組み付けることができる。   According to the present embodiment, when the keyboard instrument main body KBU is assembled to the support unit SU, the key instrument main body KBU is temporarily positioned in the front-rear and right-and-left directions by being inserted into the receiving port 33. At this time, the neck portions 45Aa and 45Ba of the flange-shaped member 45 are guided by the guide portions 34A and 34B and are reliably guided to the receiving ports 33A and 33B. In addition, when the hook-like member 45 is inserted into the receiving port 33, the positional relationship can be visually confirmed, so that the position can be easily registered. Therefore, there is little risk of injury such as pinching a finger, and the keyboard instrument main body KBU and the support unit SU are not unnecessarily contacted, so there is little risk of damaging both. Therefore, the keyboard instrument body KBU can be easily assembled to the support unit SU without causing injury or damaging the keyboard instrument body KBU or the support unit SU.

本実施の形態によればまた、鍵盤楽器本体KBUが支持体ユニットSUに対して着脱自在であるので、両者を切り離して搬送でき、しかも、支持体ユニットSUは、側板11L、11R、前脚12L、12R、下側ステイ13L、13R、上側ステイ20及び背面板14で連結されて、一体的なものとなってそれ自身高い剛性を有するので、鍵盤楽器本体KBUが着脱される際に安定しており、鍵盤楽器本体KBUの着脱作業が容易である。特に、下側ステイ13L、13Rが断面コ字状であって、前脚12と側板11の下部同士を連結するので、支持体ユニットSUの高い剛性が確保される。   According to the present embodiment, the keyboard instrument body KBU is also detachable from the support unit SU, so that both can be transported separately, and the support unit SU includes the side plates 11L and 11R, the front legs 12L, 12R, the lower stays 13L and 13R, the upper stay 20 and the back plate 14 are connected to each other and have a high rigidity. Therefore, the keyboard instrument body KBU is stable when being attached or detached. The keyboard instrument body KBU can be easily attached and detached. In particular, since the lower stays 13L and 13R have a U-shaped cross section and connect the lower portions of the front leg 12 and the side plate 11, high rigidity of the support unit SU is ensured.

なお、この観点からは、側板11L、11R同士を連結するものは、背面板14に限られず、例えば、棚板等であってもよく、上記鍵盤楽器本体KBUにおいては一部を成している部材の1つを、側板11L、11Rの連結に用いた構成であってもよい。

また、下側ステイ13は、前脚12の後面に当接し、妻土台のように前脚12より前方に出っ張ることがないので、つまずきにくく安全で、外観も良好である。さらに、下側ステイ13を前脚12、側板11にネジ37、38で締結固定する部分は、コ字状の下側ステイ13の内側に隠れるので、外部から見えにくく、外観が良好である。さらには、下側ステイ13の後部がペダルユニットPKUの逃げ部PKUaによっても隠れるので、外観が一層良好である。よって、鍵盤楽器本体KBUを支持する構造部分(支持体ユニットSU)の剛性を確保しつつ鍵盤楽器1の外観を向上させることができる。
From this point of view, what connects the side plates 11L and 11R is not limited to the back plate 14, but may be, for example, a shelf plate or the like, and forms part of the keyboard instrument body KBU. The structure used for connection of the side plates 11L and 11R may be sufficient as one of the members.

Further, the lower stay 13 is in contact with the rear surface of the front leg 12 and does not protrude forward from the front leg 12 like a wife base, so that it is hard to trip and is safe and has a good appearance. Furthermore, the portion where the lower stay 13 is fastened and fixed to the front leg 12 and the side plate 11 with screws 37 and 38 is hidden inside the U-shaped lower stay 13, so that it is difficult to see from the outside and the appearance is good. Furthermore, since the rear portion of the lower stay 13 is also hidden by the escape portion PKUa of the pedal unit PKU, the appearance is further improved. Therefore, it is possible to improve the appearance of the keyboard instrument 1 while ensuring the rigidity of the structural portion (support unit SU) that supports the keyboard instrument body KBU.

なお、ネジ37、38に代えて、ネジ以外の締結具を採用してもよい。   Note that fasteners other than screws may be employed instead of the screws 37 and 38.

なお、鉤状部材45と受け口33とは、例示した形状に限定されるものでなく、係合させる際に目視で確認でき、且つ鍵盤楽器本体KBUの仮位置決めができるような形状であればよい。例えば、図7に変形例を示すように、鉤状部材は、その先端部近傍に、下方に垂下した部分を有し、それ自身または山板41と共に、正面視で下方に開口した凹形状が形成されるような形状であればよい。また、受け口は、側面視において凹状に形成されていればよい。さらに、鉤状部材45及び受け口33の数も左右2つずつに限定されず、1つずつまたは3つずつ以上であってもよい。   Note that the hook-shaped member 45 and the receiving port 33 are not limited to the illustrated shapes, and may be any shapes that can be visually confirmed when engaged and can be used for temporary positioning of the keyboard instrument body KBU. . For example, as shown in a modified example in FIG. 7, the bowl-shaped member has a portion that hangs downward near the tip, and has a concave shape that opens downward in front view with itself or the mountain plate 41. Any shape that can be formed may be used. Moreover, the receiving port should just be formed in the concave shape in the side view. Furthermore, the number of the hook-shaped member 45 and the receiving port 33 is not limited to two each on the left and right, and may be one or three or more.

図7(a)は、鉤状部材の第1の変形例を示す正面図、同図(b)は側面図である。図7(c)は、鉤状部材の第2の変形例を示す正面図である。図7(d)は、鉤状部材の第3の変形例及び受け部材の変形例を示す平面図、同図(e)は正面視による断面図である。   Fig.7 (a) is a front view which shows the 1st modification of a bowl-shaped member, The same figure (b) is a side view. FIG.7 (c) is a front view which shows the 2nd modification of a bowl-shaped member. FIG.7 (d) is a top view which shows the 3rd modification of a bowl-shaped member, and the modification of a receiving member, The same figure (e) is sectional drawing by a front view.

例えば、鉤状部材45に代えて、図7(a)、(b)に示すように、L字状の鉤状部材145を設ける。鉤状部材145の先端部は、下方に垂下し、山板41との間に生じた凹形状部分が、受け口33と係合する。あるいは、図7(c)に示すように、鉤状部材245を設ける。鉤状部材245は、正面視において、それ自身に、正面視で下方に開口した逆U字状の凹形状部分を有し、この凹形状部分が、受け口33と係合する。   For example, instead of the hook-shaped member 45, as shown in FIGS. 7A and 7B, an L-shaped hook-shaped member 145 is provided. The distal end portion of the hook-shaped member 145 hangs downward, and the concave portion generated between the top plate 41 engages with the receiving port 33. Alternatively, as shown in FIG. 7C, a hook-like member 245 is provided. The hook-shaped member 245 has an inverted U-shaped concave portion that opens downward in the front view in the front view, and the concave portion engages with the receiving port 33.

あるいは、図7(d)、(e)に示すように、受け部材30に代えて受け部材130を設ける。受け部材130は、受け口33に代わる凹状の穴で成る受け口133を有すると共に、ガイド部34に代わる、受け口133に連設されるガイド部134を有する。さらに、鉤状部材45に代えて、L字状で、先端部が下方に垂下した鉤状部材345を設ける。この構成では、鉤状部材345の垂下した下端部がガイド部134に案内されて、受け口133に嵌入され、それにより、前後及び左右方向の仮位置決めがなされる。   Alternatively, as shown in FIGS. 7D and 7E, a receiving member 130 is provided instead of the receiving member 30. The receiving member 130 has a receiving port 133 formed of a concave hole in place of the receiving port 33, and has a guide portion 134 that is connected to the receiving port 133 instead of the guide portion 34. Further, instead of the hook-shaped member 45, a hook-shaped member 345 having an L shape and a tip portion depending downward is provided. In this configuration, the suspended lower end portion of the hook-shaped member 345 is guided by the guide portion 134 and is inserted into the receiving port 133, whereby temporary positioning in the front-rear and left-right directions is performed.

このように、これら変形例によっても、上記実施の形態と同様の効果を奏することができる。なお、このような変形例は例示であり、同様の機能を果たせば、他の形状、組み合わせも採用可能である。   As described above, the same effects as those of the above-described embodiment can also be obtained by these modified examples. In addition, such a modification is an illustration, and if the same function is performed, another shape and combination are also employable.
