Although illustration is omitted, minute unevenness is formed on the surface of the contact surface 962A. Therefore, when the housing 2 is installed on the installation surface, the adhesion between the surface of the installation surface and the contact surface 962A of the leg portion 90 is improved.

固定部９７は、第一部分９６１と一体に形成されている。固定部９７は、本体部９７１と、一対の突出部９７２，９７２とを備える。本体部９７１は、第一部分９６１の上面９６１Ａの中央部から上方に突出する略円柱状に形成されている。平面視において、本体部９７１の直径は、第一部分９６１の直径よりも小さい。一対の突出部９７２，９７２は、本体部９７１の前部及び後部において、側面視で下部に底辺を有する直角三角形状に設けられた、本体部９７１の外方に向けて突出する部分である。図８に示すように、一対の突出部９７２の最下部の前後方向の長さＬは、当接部９６の直径より短い。すなわち、当接部９６は、固定部９７の下側において固定部９７よりも外方に張り出して設けられる。このため、当接部９６の当接面９６２Ａは、所定の広さを有して設置面に当接できる。突出部９７２の最下部には、略水平に延びる面部である下面部９７２Ａが形成されている。図８に示すように、当接部９６の上面９６１Ａと突出部９７２の下面部９７２Ａとの間には、長さＫの隙間が形成される。本実施形態において、長さＫは約２．４mmである。 The fixed portion 97 is formed integrally with the first portion 961 . The fixed portion 97 includes a body portion 971 and a pair of projecting portions 972 , 972 . The body portion 971 is formed in a substantially columnar shape that protrudes upward from the central portion of the upper surface 961A of the first portion 961 . In plan view, the diameter of the main body portion 971 is smaller than the diameter of the first portion 961 . The pair of protruding portions 972 , 972 are portions protruding outward from the body portion 971 , which are provided in the front and rear portions of the body portion 971 in the shape of a right-angled triangle having a base at the bottom when viewed from the side. As shown in FIG. 8 , the length L of the lowermost portion of the pair of projecting portions 972 in the front-rear direction is shorter than the diameter of the contact portion 96 . That is, the contact portion 96 is provided below the fixed portion 97 so as to protrude outward from the fixed portion 97 . Therefore, the contact surface 962A of the contact portion 96 can contact the installation surface with a predetermined width. A lower surface portion 972A, which is a surface portion extending substantially horizontally, is formed at the lowest portion of the projecting portion 972 . As shown in FIG. 8, a gap of length K is formed between the upper surface 961A of the contact portion 96 and the lower surface portion 972A of the projecting portion 972. As shown in FIG. In this embodiment, length K is approximately 2.4 mm.

For this reason, an operator who manufactures the stove 1 passes through the holes 711 , 721 , 731 , 741 , and 801 one by one through the pair of projecting portions 972 , 972 from below. The fixing portion 97 is inserted through the 731, 741, and 801 from below to above. Both of the pair of protrusions 972, 972 pass through the holes 711, 721, 731, 741, 801 from below to above, so that the protrusions 972, 972 extend to the outside of the holes 711, 721, 731, 741, 801 in plan view. The lowermost portions of the pair of protrusions 972 protrude. As a result, the fixing portion 97 does not come off downward from the holes 711 , 721 , 731 , 741 , and 801 . In this manner, the legs 91, 92, 93, 94, and 95 are attached to the left front leg attachment portion 72, the left rear leg attachment portion 73, the right rear leg attachment portion 74, and the center leg attachment portion 80, respectively. . In a state in which the legs 90 are attached to the left front leg attachment portion 72, the left rear leg attachment portion 73, the right rear leg attachment portion 74, and the center leg attachment portion 80, the fixing portion 97 is inserted into the holes 711, 721, 731, 741, The contact portion 96 is arranged above the hole 801 and below the holes 711, 721, 731, 741, 801 (see FIGS. 4 and 5).

このように、筐体２の底面部２５の四隅に設けられた脚部９１，９２，９３，９４と、底面部２５の四隅から離間した中央部に設けられた脚部９５とによって、筐体２が設置面に対して支持される。ユーザがコンロ１の使用時に点火操作を行った場合、操作つまみ１１及び操作つまみ１１に嵌合する操作軸６３２が筐体２に対して後方に押し込まれる。コンロ１は、グリルを備えず小型に構成されているため、コンロ１の重量は一般的なコンロの重量に比べて軽い。また、左右の操作軸６３２，６３２は、コンロ１の左右方向における中央部から左方又は右方にずれた位置に配置された状態で前後方向に延びている。このため、点火操作によって操作軸６３２が後方に押し込まれることに応じて、筐体２を後方に押し込む力が、筐体２の左右方向における中央部から左右方向にいずれかにずれた位置に対して作用しやすい。 In this way, the legs 91, 92, 93, and 94 provided at the four corners of the bottom surface portion 25 of the housing 2 and the leg portion 95 provided at the central portion away from the four corners of the bottom surface portion 25 make the housing 2 is supported against the installation surface. When the user performs an ignition operation while using the stove 1 , the operation knob 11 and the operation shaft 632 fitted to the operation knob 11 are pushed backward with respect to the housing 2 . Since the stove 1 is compact without a grill, the weight of the stove 1 is lighter than that of a general stove. Further, the left and right operation shafts 632 , 632 extend in the front-rear direction while being arranged at positions deviated leftward or rightward from the central portion of the stove 1 in the left-right direction. Therefore, when the operation shaft 632 is pushed rearward by the ignition operation, the force pushing the housing 2 rearward is shifted from the central portion of the housing 2 in the left-right direction to any position in the left-right direction. easy to act.

コンロ１は、筐体２の底面部２５の四隅に加えて、底面部２５の中央部にも脚部９５を備える。よって、点火操作が行われた場合であっても、コンロ１が位置ずれすることが抑制される。また、前述したように、脚部９０の当接面９６２Ａには微細な凹凸が形成されているので、設置面と当接面９６２Ａとの間の密着性による摩擦力によっても、コンロ１の位置ずれが軽減される。 The stove 1 has legs 95 in the central portion of the bottom portion 25 in addition to the four corners of the bottom portion 25 of the housing 2 . Therefore, even when the ignition operation is performed, displacement of the stove 1 is suppressed. In addition, as described above, since the contact surface 962A of the leg portion 90 is formed with fine irregularities, the position of the stove 1 is also affected by the frictional force due to the close contact between the installation surface and the contact surface 962A. Misalignment is reduced.

図１０を参照して、筐体２に取り付けられた脚部９０の配置について説明する。直線Ｍは、筐体２の底面部２５の四隅に設けられた脚部９１，９２，９３，９４のうち最下部の当接面９６２Ａの上下方向における位置を示す。前述したように、中央脚取付部８０の底面８０２は、左前脚取付部７２、左後脚取付部７３、右後脚取付部７４及び中央脚取付部８０における底面７１２，７２２，７３２，７４２よりも上方に配置される。このため、図１０のＷ領域内に示すように、底面部２５の中央部に取り付けられた脚部９５の最下部である当接面９６２Ａは、直線Ｍよりも僅かに上方に配置される。筐体２の製造時において、脚部９５の最下部である当接面９６２Ａは、直線Ｍよりも約０．５mm上方に配置される。 The arrangement of the legs 90 attached to the housing 2 will be described with reference to FIG. A straight line M indicates the vertical position of the lowermost contact surface 962A of the legs 91 , 92 , 93 , and 94 provided at the four corners of the bottom surface portion 25 of the housing 2 . As described above, the bottom surface 802 of the central leg mounting portion 80 is located below the bottom surfaces 712 , 722 , 732 , 742 of the left front leg mounting portion 72 , the left rear leg mounting portion 73 , the right rear leg mounting portion 74 and the center leg mounting portion 80 . are also placed above. Therefore, as shown in the region W of FIG. 10, the contact surface 962A, which is the lowest portion of the leg portion 95 attached to the central portion of the bottom portion 25, is arranged slightly above the straight line M. At the time of manufacturing the housing 2, the contact surface 962A, which is the lowermost portion of the leg portion 95, is arranged above the straight line M by about 0.5 mm.

前述したように、筐体２の底面部２５には、コンロバーナ４を底面部２５に取り付けるための取付台３０，３０が設けられる（図２及び図３参照）。このため、コンロバーナ４の重量による荷重が取付台３０を介して底面部２５に加わる。取付台３０の壁部３６及び上側部３７は、天板３を下側から支持するので、天板３の重量による荷重が取付台３０の脚部３１を介して内側固定部３９に加わる。特に、調理中等のコンロ１の使用時には、バーナヘッド４２，４２の火炎の熱によって天板３のバーナ開口の近傍の部分が熱膨張し、バーナ開口同士の間の位置である天板３の中央部が下方に変位するように変形する熱歪みが生じやすい。このため、内側固定部３９に、天板３による荷重がより多く加わりやすくなり、この荷重が脚部３１を介して筐体２の底面部２５の中央部に加わりやすい。コンロ１はこのような状況で使用を継続されるので、使用期間の経過に応じて、底面部２５の中央部が徐々に下方に変位するように変形しやすい。仮に、中央脚取付部８０の底面８０２を直線Ｍの位置と同じ位置に予め設けた場合には、底面部２５の中央部が下方に沈み込むことで、脚部９５の当接面９６２Ａが脚部９１，９２，９３，９４それぞれの当接面９６２Ａよりも下方に突出する可能性がある。この場合、コンロ１が設置面に対して設置された状態で、コンロ１に、がたつきが生じる可能性がある。 As described above, the mounting bases 30, 30 for mounting the stove burner 4 on the bottom portion 25 of the housing 2 are provided (see FIGS. 2 and 3). Therefore, a load due to the weight of the stove burner 4 is applied to the bottom surface portion 25 via the mount 30 . Since the wall portion 36 and the upper portion 37 of the mounting base 30 support the top plate 3 from below, the load due to the weight of the top plate 3 is applied to the inner fixing portion 39 via the leg portions 31 of the mounting base 30 . In particular, when the stove 1 is used for cooking, etc., the heat of the flames of the burner heads 42, 42 thermally expands the portion of the top plate 3 near the burner openings, and the central portion of the top plate 3, which is the position between the burner openings, expands. Thermal strain is likely to occur in which the portion is deformed so as to be displaced downward. Therefore, a larger load from the top plate 3 is likely to be applied to the inner fixed portion 39 , and this load is likely to be applied to the central portion of the bottom portion 25 of the housing 2 via the legs 31 . Since the stove 1 is continuously used in such a situation, the central portion of the bottom portion 25 tends to be deformed so as to be gradually displaced downward as the period of use elapses. If the bottom surface 802 of the central leg mounting portion 80 were previously provided at the same position as the straight line M, the central portion of the bottom surface portion 25 would sink downward, causing the contact surface 962A of the leg portion 95 to move downward. There is a possibility of protruding downward from the contact surface 962A of each of the portions 91, 92, 93, and 94. In this case, there is a possibility that the stove 1 will rattle when it is installed on the installation surface.

このことを踏まえて、コンロ１は、中央脚取付部８０の底面８０２を、右前脚取付部７１、左前脚取付部７２、左後脚取付部７３、及び右後脚取付部７４における底面７１２，７２２，７３２，７４２よりも上方になるように予め形成している。これにより、コンロ１の使用期間の経過に応じて底面部２５の中央部が下方に変位した場合に、脚部９５の当接面９６２Ａが、脚部９１，９２，９３，９４，９５の当接面９６２Ａと上下方向において同じ位置になり、コンロ１が設置面に対して安定して設置される。 Based on this, the stove 1 is configured such that the bottom surface 802 of the central leg mounting portion 80 is replaced with the bottom surfaces 712, 712, 712, 712, It is formed in advance so as to be above 722 , 732 , 742 . As a result, when the central portion of the bottom portion 25 is displaced downward with the passage of the usage period of the stove 1, the contact surface 962A of the leg portion 95 is brought into contact with the leg portions 91, 92, 93, 94, and 95. It becomes the same position in the vertical direction as the contact surface 962A, and the stove 1 is stably installed with respect to the installation surface.

なお、前述したように、脚部９５の当接部９６の上面９６１Ａと突出部９７２の下面部９７２Ａとの間には、長さＫの隙間が形成される（図８参照）。図１０のＷ領域に示すように、脚部９５は、中央脚取付部８０の底面８０２を、突出部９７２の下面部９７２Ａと当接部９６の上面９６１Ａとの間に挟んだ状態で、中央脚取付部８０に固定される。当接部９６の上面９６１Ａと突出部９７２の下面部９７２Ａとの間の長さが長さＫであることに起因して、突出部９７２の下面部９７２Ａ、中央脚取付部８０の底面８０２、当接部９６の上面９６１Ａとのそれぞれの間に隙間が生じる。この隙間が中央脚取付部８０に対する脚部９５の上下方向における遊びとして作用する。 As described above, a gap of length K is formed between the upper surface 961A of the contact portion 96 of the leg portion 95 and the lower surface portion 972A of the projecting portion 972 (see FIG. 8). As shown in region W in FIG. 10 , the leg portion 95 sandwiches the bottom surface 802 of the central leg mounting portion 80 between the lower surface portion 972A of the projecting portion 972 and the upper surface 961A of the contact portion 96, and the center It is fixed to the leg attachment portion 80 . Due to the length K between the upper surface 961A of the contact portion 96 and the lower surface portion 972A of the projecting portion 972, the lower surface portion 972A of the projecting portion 972, the bottom surface 802 of the central leg mounting portion 80, A gap is generated between the contact portion 96 and the upper surface 961A. This gap acts as play in the vertical direction of the leg portion 95 with respect to the central leg mounting portion 80 .

よって、コンロ１の使用期間があまり経過しておらず、中央脚取付部８０の底面８０２が右前脚取付部７１、左前脚取付部７２、左後脚取付部７３及び右後脚取付部７４における底面７１２，７２２，７３２，７４２よりも上方に配置された状態であっても、脚部９１，９２，９３，９４，９５のいずれの当接面９６２Ａも設置面に当接しうる。このように、コンロ１は、コンロ１の使用期間がいずれであっても、五つの脚部９０によって、設置面に対して安定して支持される。設置面には歪みや微細な凹凸等が生じていることもあるが、底面部２５の四隅及び中央部に設けられる脚部９０が、底面部２５に対して上下方向の遊びを有して設けられるので、設置面の歪みや凹凸を遊びによって吸収し、筐体２が安定して設置面に支持される。また、脚部９０の当接面９６２Ａを最下部に有する第二部分９６２は、第一部分９６１よりも硬度が低いエラストマーで構成されているので、第二部分９６２が設置面に対してクッションの役割を果たす。これにより、設置面に対する筐体２の安定性が向上する。 Therefore, the period of use of the stove 1 has not passed much, and the bottom surface 802 of the central leg mounting portion 80 is not in the right front leg mounting portion 71, the left front leg mounting portion 72, the left rear leg mounting portion 73, and the right rear leg mounting portion 74. Even in the state of being arranged above the bottom surfaces 712, 722, 732, 742, the contact surfaces 962A of any of the legs 91, 92, 93, 94, 95 can contact the installation surface. Thus, the stove 1 is stably supported on the installation surface by the five legs 90 no matter how long the stove 1 is used. Although the installation surface may be distorted or slightly uneven, the legs 90 provided at the four corners and the center of the bottom surface 25 are provided with play in the vertical direction with respect to the bottom surface 25. Therefore, the distortion and unevenness of the installation surface are absorbed by play, and the housing 2 is stably supported on the installation surface. In addition, the second portion 962 having the contact surface 962A of the leg portion 90 at the bottom is made of an elastomer having a hardness lower than that of the first portion 961, so the second portion 962 acts as a cushion for the installation surface. fulfill This improves the stability of the housing 2 with respect to the installation surface.

以上説明したように、コンロ１は、筐体２の底面部２５の四隅における右前脚取付部７１、左前脚取付部７２、左後脚取付部７３及び右後脚取付部７４に、脚部９１，９２，９３，９４を備える。また、コンロ１は、底面部２５の中央部における中央脚取付部８０にも、脚部９５を備える。このため、コンロ１が薄型の筐体２を採用し、コンロ１自体の重量が比較的軽くても、点火操作において燃料調整部６３の操作軸６３２が後方に押し込みながら回動された場合にコンロ１に位置ずれが生じ難い。 As described above, the stove 1 has legs 91 attached to the right front leg attachment portion 71, the left front leg attachment portion 72, the left rear leg attachment portion 73, and the right rear leg attachment portion 74 at the four corners of the bottom portion 25 of the housing 2. , 92, 93, 94. The stove 1 also has a leg portion 95 on the central leg attachment portion 80 in the central portion of the bottom portion 25 . For this reason, even if the stove 1 adopts the thin housing 2 and the weight of the stove 1 itself is relatively light, when the operation shaft 632 of the fuel adjustment unit 63 is pushed backward and rotated during the ignition operation, the stove will 1 is less likely to be misaligned.

コンロ１において、左右の燃料調整部６３，６３の操作軸６３２，６３２は、それぞれ、コンロ１の左右方向における中央部から左方又は右方にずれた位置に配置された状態で前後方向に延びている。このため、点火操作によって操作軸６３２が後方に押し込まれることに応じて、筐体２を後方に押し込む力が、筐体２の左右方向における中央部から左右方向にいずれかにずれた位置に対して作用しやすい。中央脚取付部８０及び脚部９５は、筐体２の底面部２５のうち左右方向における中央部に設けられるので、左右の操作軸６３２，６３２のいずれが操作された場合にも、コンロ１に位置ずれが生じ難い。 In the stove 1, the operation shafts 632, 632 of the left and right fuel adjustment portions 63, 63 extend in the front-rear direction while being arranged at positions shifted leftward or rightward from the central portion of the stove 1 in the left-right direction. ing. Therefore, when the operation shaft 632 is pushed rearward by the ignition operation, the force pushing the housing 2 rearward is shifted from the central portion of the housing 2 in the left-right direction to any position in the left-right direction. easy to act. Since the central leg mounting portion 80 and the leg portion 95 are provided in the central portion in the horizontal direction of the bottom surface portion 25 of the housing 2, the stove 1 can be operated even when either of the left and right operation shafts 632, 632 is operated. Displacement is less likely to occur.

コンロ１は、筐体２の底面部２５のうち、コンロ１全体の重心の位置となりやすい左右のバーナ本体４０，４０のそれぞれの間の位置に中央脚取付部８０を設ける。このため、底面部２５の四隅の脚部９１，９２，９３，９４に加えて、中央脚取付部８０に脚部９５が取り付けられることによって、点火操作時におけるコンロ１の位置ずれが抑制される。 The stove 1 is provided with a central leg mounting portion 80 at a position between the left and right burner bodies 40, 40, which tends to be the center of gravity of the entire stove 1, in the bottom portion 25 of the housing 2. - 特許庁Therefore, in addition to the legs 91, 92, 93, and 94 at the four corners of the bottom surface 25, the legs 95 are attached to the central leg attachment 80, thereby suppressing displacement of the stove 1 during the ignition operation. .

コンロ１において、取付台３０，３０のそれぞれにおける壁部３６及び上側部３７が、天板３を下側から支持している。また、コンロ１の使用時には、天板３の中央部に熱歪みが生じやすいので、筐体２の底面部２５の中央部は、使用期間の経過に応じて、天板３からの荷重によって下方に沈み込むように変形しやすい。このような場合であっても、コンロ１は、製造時において、脚部９５の最下部である当接面９６２Ａが、直線Ｍよりも僅かに上方に配置されるように底面部２５を構成している。よって、コンロ１は、その使用状況に応じて、筐体２を設置面に対して安定して設置することができる。 In the stove 1, the wall portion 36 and the upper portion 37 of each of the mounts 30, 30 support the top plate 3 from below. Also, when the stove 1 is in use, the central portion of the top plate 3 is likely to be thermally distorted. It is easy to deform as if it were sinking into. Even in such a case, the bottom portion 25 of the stove 1 is configured so that the contact surface 962A, which is the lowest portion of the leg portion 95, is arranged slightly above the straight line M at the time of manufacture. ing. Therefore, the stove 1 can stably install the housing 2 on the installation surface according to the usage conditions.

底面部２５において、右前脚取付部７１、左前脚取付部７２、左後脚取付部７３、右後脚取付部７４及び中央脚取付部８０のそれぞれに対して、脚部９０が上下方向における遊びを有して取り付けられる。よって、コンロ１の設置面に凹凸等、僅かに歪みが生じている場合であっても、コンロ１は、筐体２を設置面に対して安定して設置できる。 In the bottom surface portion 25, the leg portion 90 has play in the vertical direction with respect to each of the right front leg attachment portion 71, the left front leg attachment portion 72, the left rear leg attachment portion 73, the right rear leg attachment portion 74, and the center leg attachment portion 80. mounted with Therefore, even if the mounting surface of the stove 1 is slightly distorted such as unevenness, the housing 2 of the stove 1 can be stably mounted on the mounting surface.

脚部９０において、当接部９６が固定部９７よりも外方に張り出して設けられるので、当接部９６の当接面９６２Ａは、所定の広さを有して設置面に当接できる。よって、設置面に対して筐体２が安定して設置される。 In the leg portion 90, the contact portion 96 is provided so as to protrude outward from the fixed portion 97, so that the contact surface 962A of the contact portion 96 can contact the installation surface with a predetermined width. Therefore, the housing 2 is stably installed on the installation surface.

脚部９０の当接部９６のうち第一部分９６１は所定の硬度を有する合成樹脂で構成されるので、当接部９６は一定の強度を有する。また、第二部分９６３は第一部分９６１よりも硬度が低いエラストマーで構成されるので、コンロ１の設置面に対して第二部分９６３がクッションの役割を果たし、設置面に対する筐体２の安定性が向上する。また、第二部分９６３の最下部にあたる当接面９６２Ａには、微細な凹凸が形成されるので、筐体２が設置面に設置された状態で、設置面と当接面９６２Ａとの間の密着性が向上する。このため、点火操作時にコンロ１の位置ずれが生じ難い。 Since the first portion 961 of the contact portion 96 of the leg portion 90 is made of a synthetic resin having a predetermined hardness, the contact portion 96 has a certain strength. In addition, since the second portion 963 is made of an elastomer having a hardness lower than that of the first portion 961, the second portion 963 serves as a cushion against the installation surface of the stove 1, and the stability of the housing 2 against the installation surface. improves. In addition, since fine unevenness is formed on the contact surface 962A corresponding to the lowest part of the second portion 963, when the housing 2 is installed on the installation surface, there is a gap between the installation surface and the contact surface 962A. Adhesion is improved. Therefore, the position of the stove 1 is less likely to be displaced during the ignition operation.

In the above embodiment, the leg portion 90 has vertical play with respect to the right front leg attachment portion 71, the left front leg attachment portion 72, the left rear leg attachment portion 73, the right rear leg attachment portion 74, and the center leg attachment portion 80. It is preferable that the length K is longer than the thickness of the bottom surface portion 25 of the housing 2 , especially the thickness of the bottom surface 802 of the central leg mounting portion 80 , in order to be fixed to the housing 2 .

脚部９１，９２，９３，９４，９５の全てが筐体２の底面部２５に対して遊びを有して取り付けられなくてもよい。例えば、中央脚取付部８０に対して脚部９５が遊びを有して取り付けられ、その他の脚部９１，９２，９３，９４が右前脚取付部７１、左前脚取付部７２、左後脚取付部７３及び右後脚取付部７４のそれぞれに対して遊びを有さずに取り付けられてもよい。 All of the legs 91 , 92 , 93 , 94 , 95 do not have to be attached to the bottom portion 25 of the housing 2 with play. For example, the leg portion 95 is attached with play to the central leg attachment portion 80, and the other leg portions 91, 92, 93, and 94 are attached to the right front leg attachment portion 71, the left front leg attachment portion 72, and the left rear leg attachment portion. It may be attached to each of the portion 73 and the right rear leg attachment portion 74 without play.

コンロ１は、脚部９１，９２，９３，９４，９５として脚部９０を共通して用いているが、例えば、筐体２の底面部２５の四隅に設けられる脚部９１，９２，９３，９４と、底面部２５の中央部に設けられる脚部９５とが異なる形状を有していてもよい。 The stove 1 uses the legs 90 in common as the legs 91, 92, 93, 94, and 95. For example, the legs 91, 92, 93, 94 and the leg portion 95 provided in the central portion of the bottom portion 25 may have different shapes.

上記実施形態では、中央脚取付部８０の底面８０２の上下方向における位置が、右前脚取付部７１、左前脚取付部７２、左後脚取付部７３及び右後脚取付部７４それぞれの底面７１２，７２２，７３２，７４２の上下方向における位置よりも下方に設けられる。この状態で、右前脚取付部７１、左前脚取付部７２、左後脚取付部７３、右後脚取付部７４及び中央脚取付部８０に対して、脚部９０が共通して取り付けられることによって、脚部９５の当接面９６２Ａが脚部９１，９２，９３，９４の当接面９６２Ａよりも上方に配置される。この点、底面７１２，７２２，７３２，７４２，８０２のそれぞれが上下方向において同じ位置に設けられてもよい。この場合、中央脚取付部８０に対して右前脚取付部７１、左前脚取付部７２、左後脚取付部７３及び右後脚取付部７４に取り付けられる脚部よりも上下方向の長さが短い脚部が取り付けられてもよい。これによって、筐体２の底面部２５の四隅に取り付けられる脚部の最下部よりも底面部２５の中央部に取り付けられる脚部の最下部が上方に配置されてもよい。 In the above embodiment, the positions of the bottom surface 802 of the central leg mounting portion 80 in the vertical direction are the bottom surfaces 712 of the right front leg mounting portion 71, the left front leg mounting portion 72, the left rear leg mounting portion 73, and the right rear leg mounting portion 74, respectively. It is provided below the positions of 722, 732, and 742 in the vertical direction. In this state, the leg portion 90 is commonly attached to the right front leg attachment portion 71, the left front leg attachment portion 72, the left rear leg attachment portion 73, the right rear leg attachment portion 74, and the central leg attachment portion 80. , the contact surface 962A of the leg 95 is arranged above the contact surfaces 962A of the legs 91, 92, 93, and 94. As shown in FIG. In this regard, each of the bottom surfaces 712, 722, 732, 742, 802 may be provided at the same position in the vertical direction.
