[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a drop-in stove, and more particularly to a drop-in stove that is effective for a sealed type in which an operation unit is disposed on a top plate.
[0002]
[Prior art]
As shown in Fig. 7, the drop-in stove used in the system kitchen, etc. is accommodated in the opening (30) formed in the countertop (31) that is continuous with the cooking table and sink, and the stove part composed of a control device, a burner, etc. A so-called drop-in stove is generally used in which the upper open main body case (2) is dropped and fixed. FIG. 7 is a partial end view of the right end of a conventional drop-in stove. Although not shown, the operation unit for operating the control device is disposed on the top plate, and in order to prevent the hot air from leaking below the counter top (31) from the main body case (2), the main body case (2) This is a sealed drop-in stove in which almost no through holes or the like are formed in the wall.
[0003]
In particular, the illustrated one is a type in which the open part of the main body case (2) dropped into the opening (30) is covered with a heat-resistant glass plate (1) as a top plate, and the periphery of the opening (30) is provided. Is provided with a frame (3) for holding the glass plate (1).
The outer periphery flange (21) projects horizontally on the outer periphery of the upper end of the main case (2), and the outer periphery flange (21) is supported on the periphery of the opening (30) via the packing (P) for preventing spillage. By doing so, the main body case (2) is housed in a suspended state in the opening (30).
[0004]
The frame (3) includes a first flange (3a) having a substantially inverted U-shaped cross-section covering the periphery of the opening (30) of the countertop (31) and a second flange (horizontally extending into the opening (30)). 3b).
In this case, first, the main body case (2) is dropped into the opening (30), and the outer peripheral flange (21) is locked to the periphery of the opening (30) via the packing (P). Then, the frame (3) in which the glass plate (1) as the top plate is placed on the second flange (3b) is opened so that the first flange (3a) covers the upper side of the outer peripheral flange (21) ( Install at the periphery of 30). The gap between the edge of the glass plate (1) and the inner surface of the vertical surface (34) of the first flange (3a) is filled with silicon adhesive (5), and the glass plate (1) and the frame The body (3) is adhered.
[0005]
[Problems to be solved by the invention]
In the drop-in stove having such a configuration, the main body case (2) is completely sealed, and therefore primary air necessary for burning the burner accommodated in the main body case (2) cannot be taken in.
Therefore, in the front and left / right directions of the stove, the outer peripheral end (35) of the first flange (3a) is more outward than the outer peripheral flange (21) on the upper surface of the countertop (31), as shown in FIG. As shown in FIG. 8, on the rear side, which is not directly visible, the outer peripheral end (35) of the first flange (3a) and the upper surface of the countertop (31) There is a gap between them. This gap functions as an intake port (33) for combustion air.
[0006]
However, with the increase in the calorie of the burner, there is a problem that the combustion air is insufficient only at the rear air intake port (33).
According to the first and fourth aspects of the present invention, “an upper body case having an outer peripheral flange supported on the periphery of the opening formed in the countertop and a first flange covering the upper portion of the outer peripheral flange are provided. A frame, a top plate supported by the frame and covering the upper part of the main body case, and a gas burner in which an air suction portion is provided below the top plate and a flame hole protrudes above the top plate. In the drop-in stove provided, combustion air can be sufficiently taken into the main body case from between the counter top and the frame body, and displacement of the frame body from the main body case can be prevented. The challenge is to make it.
[0007]
[Means for Solving the Problems]
In order to solve the above technical problem, the means of the invention according to claim 1 is as follows: “The frame body is partially supported at a height at which the lower edge of the outer peripheral edge of the frame body does not contact the upper surface of the countertop. Positioning means for positioning the frame body on the outer peripheral flange by providing the supporting means to either the outer peripheral flange or the frame body and engaging the support means in a horizontal direction, It is provided on either the outer peripheral flange or the frame so that the supporting means is not blocked by the positioning means ”.
[0008]
By supporting the outer peripheral flange of the main body case around the periphery of the opening formed in the countertop, the main body case is housed in a suspended state in the opening. When the first flange of the frame is placed so as to cover the outer peripheral flange, the frame is partially above the outer peripheral flange by support means provided on either the outer peripheral flange or the frame. And the support means engages with the positioning means provided on the other of the outer peripheral flange and the frame body, and the frame body has a lower end of the outer peripheral end thereof. It will be positioned on the outer peripheral flange in a state of being lifted from the upper surface of the counter top.
[0009]
At this time, if the lower end of the outer periphery of the frame is lifted from the countertop over the entire circumference, the combustion air can be sucked from the entire circumference, so that the amount of suction is maximized. When it is not necessary to suck in combustion air from the entire circumference, only the lower end of the outer peripheral end on the front side of the frame body is placed on the countertop, and the lower end of the outer peripheral end on the rear side and the left and right sides can be floated. good. Alternatively, the outer peripheral end of either the rear side or the left and right following this may be floated. In this case, the frame body is installed in a state where the outer peripheral end is lifted from the counter top in two continuous directions.
[0010]
In the conventional configuration, when two or more continuous lower ends of the outer peripheral lower ends of the rectangular frame are floated, the frame cannot be stably installed. Even if two or more continuous lower ends of the outer periphery of the body are floated, it can be stably installed.
When the support means is provided on the outer peripheral flange side, the positioning means is provided on the frame body side. When the support means is provided on the frame body side, the positioning means is The support means and the positioning means may be integrated with the outer peripheral flange or the frame body, or may be separate from each other.
[0011]
Further, the support means is partially provided in the circumferential direction between the upper and lower outer flanges of the main body case and the first flange of the frame body, and the positioning means does not block between the support means. Therefore, the gap communicates with the main body case. And the primary air for combustion can be taken in in a main body case from the said clearance gap.
[0012]
Further, when the outer peripheral edge of the frame body is lifted over the entire circumference, the frame body does not contact the countertop, so that the radiant heat from the stove burner conducts heat to the countertop through the frame body. There is nothing to do.
Further, if a boil-out prevention packing is interposed between the outer peripheral flange and the counter top, boil-out during cooking does not enter the main body case from the gap.
[0013]
According to a second aspect of the present invention, in the configuration of the first aspect of the invention, “the support means is a support protrusion formed on each flange surface projecting in the front-rear direction and the left-right direction of the outer peripheral flange, The positioning means is a convex portion that hangs down from the lower surface of the first flange so as to engage with the support protrusions in the horizontal direction when the first flange is supported by the support protrusions. It is a feature.
[0014]
Since the drop-in stove has a rectangular parallelepiped shape, the main body case is a rectangular box that is open upward, and the flange surface projects in the front-rear direction and the left-right direction from the four sides of the upper end open portion of the main body case. . Also, the first flange of the frame body has a rectangular frame shape corresponding thereto, and by providing a support protrusion as a support means on each flange surface of the outer peripheral flange, the rectangular frame-shaped first flange is provided. Each side of one flange is supported by the support protrusion.
[0015]
Further, since the convex portion as the positioning means provided on the lower surface of the first flange is engaged with the inner side surface or the outer side surface of the support projection, the frame is supported by the support projection. In addition, the convex portion functions as a stopper.
According to a third aspect of the present invention, in the configuration of the second aspect of the present invention, “the convex portion is a ridge formed over the entire circumference of the lower surface of the first flange, The height is set to be lower than that of the support protrusions, and the height of the protrusions is set to be lower than the height of the support protrusions even when the protrusions are formed on the entire circumference. Thus, the ridges do not block between the support protrusions, and the air taken in from the gaps is sent between the support protrusions and below the ridges into the main body case. be able to.
[0016]
In addition, the frame having a configuration in which the first flange is provided with a ridge on the lower surface can be manufactured by a mold material by extrusion molding, and no post-processing of the mold material is required.
According to a fourth aspect of the present invention, in the configuration of the first aspect of the present invention, “the support means is a support protrusion formed so as to hang from the lower surface of the first flange, and the positioning means is The ridges are formed on the outer peripheral flange over the entire circumference, and the height of the ridges is set to be lower than the height of the support protrusions. A supporting projection suspended from the lower surface of one flange is placed on the outer peripheral flange of the main body case, and a protrusion is provided over the entire circumference on the outer peripheral flange. , And functions as a positioning means, and even if spilled or the like enters from the gap between the outer peripheral end of the frame and the countertop, it is dammed by the ridges.
[0017]
According to a fifth aspect of the present invention, there is provided a supporting means for partially supporting the frame body at a height at which a lower edge of the outer peripheral end of the frame body does not contact the upper surface of the countertop. And a positioning means for positioning the frame body in the main body case is provided so as to be interposed between the main body case and the frame body ”.
[0018]
Regarding an aspect in which the frame body is partially supported on the outer peripheral flange by the support means in a state where the frame body is lifted from the upper surface of the countertop over two or more continuous outer peripheral end lower edges. This is the same as the action of Item 1.
Further, the frame body is positioned within the main body case by the positioning means interposed between the main body case and the frame body.
[0019]
The supporting means and the positioning means may be formed separately and provided on the outer peripheral flange or the frame body, respectively, and the integrally formed one of the outer peripheral flange or the frame body may be used. It is good also as a structure provided in.
According to a sixth aspect of the present invention, in the configuration of the fifth aspect of the invention, the frame is provided with a hanging wall that enters the body case on the inner periphery of the first flange, The positioning means is a projecting portion that projects from one side of the hanging wall or the main body case to the other side ”.
[0020]
The frame body is supported in a state where the outer peripheral end lower edge is lifted from the counter top by the outer peripheral flange of the main body case or a support protrusion protruding from the frame body, and the hanging wall enters the main body case, The drooping wall and the side wall of the main body case face each other. Since a protrusion as a positioning means protrudes on each surface of the hanging wall or the side wall, a gap corresponding to the height of the protruding portion is provided between the hanging wall and the main body case. As a result, the hanging wall is positioned in the main body case.
[0021]
According to the seventh aspect of the present invention, the supporting projection and the protruding portion are integrally provided in the means of the sixth aspect of the invention. A support plate having an L-shaped cross section composed of a horizontal piece and an upright piece is attached to each flange surface projecting in the left-right direction so that the tip of the horizontal piece abuts on the drooping wall, and the protrusion is attached to the horizontal surface. It is characterized by having the tip of the piece and the support protrusion as the upright piece ”.
[0022]
Since the drop-in stove has a rectangular parallelepiped shape, the main body case becomes an open rectangular box having four side walls, and the flange surface projects in the front-rear direction and the left-right direction from each upper side to form an outer peripheral flange. Yes. In response to this, the first flange of the frame is also a rectangular frame, and four hanging walls are suspended from the four sides on the inner circumference side.
[0023]
By attaching the support plate configured in a substantially L shape to each flange surface at a position where the tip of the horizontal piece comes into contact with the hanging wall, the tip of the horizontal piece is placed in the main body case. Projecting from four directions, whereby the hanging wall is positioned between the opposing side walls of the main body case. That is, the front end of the horizontal plate functions as the protruding portion of claim 6, and the upright portion is supported by the support of claim 6 by placing the first flange on the top of the upright portion of the support plate. It will function as a protrusion.
[0024]
The invention of claim 8 is characterized in that, among the configurations of the inventions of claims 1 to 4, “the thickness of the support means in the inner and outer directions is set larger than that of the positioning means”. .
Between the first flange of the frame and the outer peripheral flange of the main body case, the positioning means is engaged only from either the inside or the outside of the support means, thereby positioning the frame. For example, when both of them are thin plate-like, or when the frame body is displaced, that is, one positioning means engages inside one support means, and the positioning means on the opposite side corresponds to it. Even when it is placed so as to engage with the outside of the support means, the deviation is small, so it is difficult to recognize the erroneous installation of the frame. If the thickness of the support means is set to be large, when the frame body is displaced and installed, the magnitude of the displacement becomes large, so that it is possible to easily recognize erroneous installation of the frame body, and Support strength can be increased.
[0025]
In order to increase the thickness of the support means in the inner and outer directions, as in the configuration of the invention according to claim 9, "the support means is a plate-like peripheral protrusion along the circumferential direction of the outer peripheral flange or the frame. And a pair of bent pieces bent inwardly or outwardly from both ends of the peripheral protrusion may be configured in a substantially U-shaped cross section.
[0026]
【The invention's effect】
As described above, in the invention according to claim 1 of the present invention, a gap communicating with the inside of the main body case is formed between two or more continuous directions between the frame body and the upper surface of the countertop. As a result, the air necessary for combustion of the burner can be effectively taken in. For example, even if the operation surface is a closed drop-in stove arranged on the top plate, the burner can be made high in calories. It becomes possible.
[0027]
Further, since the frame can be positioned in a state where the gap is formed only by being placed on the outer peripheral flange, the positioning of the frame is facilitated.
Further, when the entire periphery of the outer peripheral edge of the frame body is floated, the radiant heat from the burner is not transmitted to the counter top, so that there is no inconvenience that the counter top is overheated even if a high calorie burner is used.
[0028]
In addition to the effect of the invention of claim 1, the invention described in claim 2 is such that the frame is communicated with the lower end of the outer periphery within the main body case only by being supported by a support protrusion provided on the outer peripheral flange of the main body case. Therefore, the drop-in stove can be easily attached. In addition, since the convex portion functions as a stopper for preventing the frame body from shifting, even if an external impact or the like is applied to the frame body, it is inadvertently displaced in either the front-rear direction or the left-right direction. No force is applied to the gas burner protruding upward from the top plate.
[0029]
Since the frame is only placed on the support protrusion of the outer peripheral flange, the top plate can be removed together with the frame, and the top plate can be easily maintained.
Further, if the height of the support protrusion is set to be equal to or lower than the height from the upper surface of the conventional outer peripheral flange to the lower surface of the first flange, the height of the frame body from the counter top is set to the current height. Can be maintained.
[0030]
In addition to the effect of the invention described in claim 2, the invention described in claim 3 has the effect that the frame member with the positioning means can be easily manufactured.
In addition to the effect of the invention of claim 1, the invention of claim 4 can spill spillage or the like entering from the gap between the outer peripheral edge of the frame and the counter top, and can be dammed by the ridges. There is an effect that it is possible to surely prevent intrusion such as boiling over.
[0031]
In addition to the effect of the invention of claim 1, the invention described in claim 5 is not configured to engage the support means and the positioning means, so that the formation positions of the main body case and the frame can be freely set. There is an effect that can be set to. For this reason, the manufacturing of the main body case and the frame body is facilitated, and it is not necessary to consider the positional relationship between them when the frame body is installed on the outer peripheral flange.
[0032]
In addition to the effect of the invention of the fifth aspect, the invention according to the sixth aspect is configured such that the protruding portion as the positioning means protrudes between the hanging wall of the frame body and the side wall of the main body case. The drooping wall is surely positioned away from the side wall of the main body case by the height of the protrusion. Therefore, there is an effect that it is possible to reliably prevent radiant heat from the burner from being transmitted to the counter top via the frame.
[0033]
According to the seventh aspect of the present invention, since the support means and the positioning means are integrally configured, it is easier to manufacture and assemble a drop-in stove having a gap as an air intake port on the entire circumference of the frame body. Become.
In addition to the effects of the inventions of claims 1 to 4, the invention of claim 8 has an effect that the frame body can be surely installed at a correct position on the outer peripheral flange, and in addition to the effect of the support means. Since strength increases, there exists an effect that the stability in the installation state of the said frame improves.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
The embodiment of the present invention is implemented in a drop-in stove in which a heat source is a gas burner. As shown in FIG. 1, a gas burner (10), an output device such as an electromagnetic valve, an ignition device, etc. (not shown) The main body case (2), which is a rectangular box that is open upward, is fitted and fixed in the opening (30) formed in the countertop (31) that is continuous with the sink or cooking table, The upper rectangular open part of the main body case (2) is covered with a glass plate (1) and a frame (4) as a top plate, and a primary air suction port (10d) of the burner body (10c) serves as the glass plate (1). The burner (10) is housed in the body case (2) below, the burner head (10b) penetrates the glass plate (1), and the flame hole (10a) is positioned above the glass plate (1). It is provided.
[0035]
Note that N in the figure indicates a nozzle inserted into the primary air suction port (10d).
On the glass plate (1), an operation knob (200) for operating the heating power adjusting member (100) such as ignition / extinguishing of the gas burner (10) is provided with an operation shaft penetrating the glass plate (1). The outer peripheral flange (22) projects horizontally across the entire outer periphery of the upper end of the main body case (2). The outer peripheral flange (22) is supported on the peripheral edge of the opening (30) via a spill-resistant packing (P), so that the body case (2) is suspended in the opening (30). Will be housed in the state.
[0036]
In order to prevent hot air from leaking from the main body case (2) to the lower side of the counter top (31), no through-holes are formed in the constituent walls of the main body case (2).
Further, as shown in FIG. 2, the outer peripheral flange (22) is cut and raised upward from the outer peripheral end of each side of the outer peripheral flange (22) to form support protrusions (23) as support means. .
[0037]
The plate thickness of the outer peripheral flange (22) is 0.8 mm to 1.0 mm, and the support protrusion (23) is a plate shape having a circumferential length of 20 mm and a height of 5 mm. Two to three portions are formed on each of the flange surfaces extending in the front-rear direction and the left-right direction constituting 22).
In this example, the support protrusion (23) is formed by cutting and raising a part of the outer peripheral flange (22), but a separate member may be attached by welding or the like.
[0038]
The frame (4) includes a horizontal first flange (4a) covering the outer peripheral flange (22), a first hanging wall (4b) hanging from the inner peripheral end of the first flange (4a), and a first hanging wall A second flange (4c) extending horizontally inward from the lower end of (4b), and a bent piece (4d) bent obliquely downward from the outer peripheral end of the first flange (4a) Is configured to do.
[0039]
The glass plate (1) is placed on the second flange (4c) and held by a silicon adhesive (5) provided between the side surface of the glass plate (1) and the first hanging wall (4b). Has been. This glass plate (1) is a rectangular plate made of heat-resistant glass slightly smaller than the opening (30), and is used to project the burner head (10b) of the gas burner (10) housed in the main body case (2). A burner insertion hole (11) is opened. In FIG. 1, K disposed between the burner head (10b) and the burner insertion hole (11) is a buffer member.
[0040]
Insert the burner head (10b) of the burner (10) through the burner insertion hole (11), First When the frame (4) is installed so as to cover the outer peripheral flange (22) with one flange (4a), the first flange (4a) is supported by the support protrusion (23) of the outer peripheral flange (22). . In this supported state, a gap 50 having a height of 5 mm, that is, a height of 5 mm, is formed between the upper surface of the outer peripheral flange 22 and the lower surface of the first flange 4a. Will be formed.
[0041]
Further, as shown in FIG. 2, a projecting piece (40) as a positioning means is formed at each position corresponding to the outer surface portion of the support projection (23) on the lower surface of the first flange (4a). .
In order to install the drop-in stove of the present embodiment, first, along the periphery of the opening (30), a watertight packing (P ). Usually, the packing (P) is bonded to the lower surface of the outer peripheral flange (22). Thereafter, the main body case (2) is dropped into the opening (30) of the countertop (31), and the outer peripheral flange (22) is locked to the periphery of the opening (30) via the packing (P). As the packing (P), a heat insulating type is used, which also serves to prevent heat conduction to the countertop (31).
[0042]
Next, the frame (4) is placed on the periphery of the opening (30) so that the upper part of the outer peripheral flange (22) is covered with the first flange (4a). Then, the frame body (4) is supported by the plurality of support protrusions (23) protruding from the respective flange surfaces constituting the outer peripheral flange (22), and the first flange is provided on each outer surface of the support protrusion (23). The inner side surfaces of the projecting pieces (40) projecting from the lower surface of (4a) come into contact with each other. Thereby, the shift | offset | difference to the front-back direction and the left-right direction of a frame (4) will be prevented by the protrusion (40). In other words, the projecting piece (40) functions as a stopper for preventing the frame (4) from shifting in the horizontal direction.
[0043]
In the above support state of the frame (4), between the lower end of the outer periphery of the bent piece (4d) and the upper surface of the countertop (31), as shown in FIG. The angle of inclination and the length of the bent piece (4d) with respect to the first flange (4a) are set so that the gap is provided. The gap serves as an air intake (33) for taking in primary air for combustion of the gas burner (10).
[0044]
This completes the attachment of the drop-in stove to the countertop (31).
A finished product of a drop-in stove in which the frame (4) and the glass plate (1) are assembled to the main body case (2) may be dropped as described above.
The primary air required for the burner burns from the air intake port (33) formed over the entire circumference between the lower end of the outer periphery of the bent piece (4d) and the countertop (31) to the outer peripheral flange (22). Since the air is effectively taken into the body case (2) through the gap (50) between the first flange (4a), there is no shortage of combustion air. The secondary air can be taken from the upper surface of the glass plate (1) by projecting the flame hole (10a) from the glass plate (1).
[0045]
Moreover, since the air intake port (33) is set to about 3 mm, there is no inconvenience that the appearance is deteriorated, and the outer peripheral flange (22) is supported on the peripheral edge of the opening (30) through the packing (P). Therefore, even if dirt such as spilled water enters the lower part of the frame (4) from the air intake (33), the packing (P) prevents entry into the main body case (2). Can do.
[0046]
Also, since the frame (4) is not in direct contact with the countertop (31), the radiant heat from the body case (2) is not transmitted to the countertop (31), and the countertop (31) The temperature will not rise.
In the above embodiment, the protrusion (40) is partially provided as a stopper for preventing the frame (4) from shifting, but as shown in FIG. 3, it is set lower than the height of the support protrusion (23). The ridge (41) may be provided so as to hang down over the entire circumference of the lower surface of the first flange (4a). For example, if the height of the ridge (41) is set to 2 mm, the height of the support protrusion (23) is 5 mm. Therefore, at the position where the support protrusion (23) is not formed, the outer peripheral flange ( 22) A gap of 3 mm is generated from the upper surface of the ridge (41) to the lower end of the ridge (41), and the air taken in from the air intake port (33) passes through the gap of 3 mm in height, It will be sent into the body case (2).
[0047]
On the contrary, as shown by the two-dot chain line in FIG. 3, the ridges (41a) are provided on the outer peripheral flange (22) over the entire circumference as positioning means, and the support projections (23a) are It is also possible to adopt a configuration in which the support protrusion (23a) is made higher than the protrusion (41a) by partially hanging from one flange (4a). In this case, the ridge (41a) functions as a weir that dams up dirt such as spillage that enters the frame (4) from the air intake port (33) into the body case (2). It is possible to reliably prevent the dirt from entering.
[0048]
In the structure shown in FIG. 4, peaks (24a), (24b) and (24c) having an inverted V-shaped cross section are partially formed on the outer peripheral flange (22) as support means. In the case of this embodiment, when the first flange (4a) of the frame (4) is placed on the outer peripheral flange (22), the first flange (4a) is in point contact with the plurality of peak portions (24a). Thus, air can be taken in between the ridge (24a) and the ridge (24a).
[0049]
In this embodiment, the ridges (24b) (24c) projecting inward and outward are also partially projected on the side wall of the main body case (2). The protrusion (24b) protruding outward as a spacer prevents the main body case (2) from sticking to the inner peripheral side surface of the opening (30), and the protrusion protruding inward as positioning means. The frame (4) is positioned so that (24c) is brought into contact with the first hanging wall (4b).
[0050]
In addition, as a positioning means, the structure which makes the peak part which protrudes outward from a 1st drooping wall (4b) contact | abut to the side wall of a main body case (2) may be sufficient. As the support means, the support protrusion (23a) suspended from the first flange (4a) in the above embodiment may be employed.
FIG. 5 is an explanatory diagram of a drop-in stove according to the fourth embodiment, and has a substantially L-shaped cross section composed of an upright piece (61) and a horizontal piece (62) as shown in FIG. The plate-like support plate (6) is attached to each flange surface of the outer peripheral flange (22). The support plate (6) has the lower surface of the horizontal piece (62) positioned on the outer peripheral flange (62) so that the tips of all the horizontal pieces (62) are in contact with the outer surface of the first hanging wall (4b). It is attached to the upper surface of 22) by welding or the like. As a result, the tip of the horizontal piece (62) protrudes in all directions on the inner peripheral side of the outer peripheral flange (22), and the upright piece (61) protrudes upward, each of which has positioning means and support It will function as a means.
[0051]
In each of the above embodiments, the height of the support protrusion (23) and the peak portion (24) is the height from the outer peripheral flange (22) to the first flange (4a) of the frame (4) in the conventional drop-in stove. If the height is equal to or less than that, the height from the counter top (31) to the first flange (4a) will not be higher than necessary, and the conventional frame height will be maintained. can do.
[0052]
Further, as shown in FIG. 9, the supporting means includes a peripheral protrusion (71) along the circumferential direction of the outer peripheral flange (22) and a pair of bent pieces (72) formed by bending both ends inward. The cross section may be substantially U-shaped. In this case, the thickness of the support means in the inner / outer direction (direction intersecting the circumferential direction) corresponds to the distance from the free end of the bent piece (72) to the peripheral protrusion (71). The thickness in the inner and outer directions can be set larger than that of the positioning means. Therefore, when the frame (4) provided with positioning means is put on the main body case (2), the positioning means engages with the outer surface of the peripheral protrusion (71) or the free end of the bent piece (72). When the correct positional relationship for engagement is removed, the frame (4) is displaced by the distance corresponding to the thickness of the support means. Since this distance corresponds to the thickness of the support means (the length of the bent piece (72)) and is relatively large, it can be recognized that the frame (4) has been installed at an excessive position. it can.
