Description

Technical Field

[0001] The present disclosure relates to a panel storage container. Background Art

[0002] Panel storage containers for storing multiple panels are known. For example, Japanese Patent Application Laid-Open No. 2017-37945 describes a storage container comprising a container body for storing multiple wafers and a lid for closing an opening of the container body. Utility Model Content

[0003] In the storage container described in Japanese Patent Application Laid-Open No. 2017-37945, the lid and the container body are sealed by a sealing member (or stopper member). Sometimes, the sealing member is attached to the lid by fitting the sealing member between the lid and the container body into a groove provided in the lid. In such a structure, it is desirable to have a structure that prevents the sealing member from being easily separated from the groove.

[0004] The present disclosure describes a panel storage container capable of more firmly holding a sealing member.

[0005] The panel accommodating container of one aspect of the present disclosure includes: a container body having an opening for accommodating a plurality of panels; and a cover body for closing the opening. The cover body includes: a cover body having a first surface and a second surface opposite to the first surface, the first surface being a surface opposite to the plurality of panels accommodated in the container body in a first direction when the cover body closes the opening; and a sealing member arranged on the first surface for sealing between the cover body and the container body. The first surface is provided with a groove portion which is recessed in the first direction to hold the sealing member. The groove portion is defined by a first side wall and a second side wall which face each other in a second direction intersecting the first direction, and a bottom wall connecting the first side wall and the second side wall. The first side wall is provided with a first space connected to the groove portion, and the sealing member includes a first protrusion portion arranged in the first space.

[0006] In the panel storage container, the sealing member is retained in the groove. A first space connected to the groove is provided on a first sidewall defining the groove, and the first protrusion of the sealing member is disposed in the first space. Thus, even if a force is applied to the sealing member in a direction causing it to disengage from the groove, the first protrusion disposed in the first space interferes with the first sidewall, making it less likely for the sealing member to disengage from the groove. As a result, the sealing member can be more securely retained.

[0007] In this case, even if a force is applied to the sealing member in a direction to separate from the groove, the first protrusion provided in the through hole interferes with the first side wall, so that the sealing member is not easily separated from the groove.

[0008] In this case, even if a force is applied to the sealing member in a direction to separate from the groove, the first protrusion provided in the groove interferes with the first side wall, so that the sealing member is not easily separated from the groove.

[0009] The second sidewall may be provided with a second space connected to the groove. The sealing member may include a second protrusion provided in the second space. With this configuration, when a force is applied to the sealing member in a direction to disengage it from the groove, not only will the first protrusion provided in the first space interfere with the first sidewall, but the second protrusion provided in the second space will also interfere with the second sidewall, thereby making it more difficult for the sealing member to disengage from the groove. As a result, the sealing member can be more securely held.

[0010] In this case, even if a force is applied to the sealing member in a direction to separate from the groove, the second protrusion provided in the through hole interferes with the second side wall, so that the sealing member is not easily separated from the groove.

[0011] In this case, even if a force is applied to the sealing member in a direction in which the sealing member is separated from the groove, the second protrusion provided in the groove interferes with the second side wall, so that the sealing member is not easily separated from the groove.

[0012] The bottom wall may be provided with a disassembly hole that penetrates the cover body in the first direction. With this configuration, a rod-shaped member can be inserted into the disassembly hole to apply force to the sealing member in a direction that causes it to disengage from the groove. Therefore, the sealing member can be easily disassembled.

[0013] According to the present disclosure, the sealing member can be held more firmly. BRIEF DESCRIPTION OF THE DRAWINGS

[0064] Reference Figure 1 A panel storage container according to one embodiment will be described. Figure 1 This is an exploded perspective view of a panel storage container according to one embodiment. Figure 1The panel storage container 1 shown is a container for storing a plurality of panels. The panel storage container 1 is, for example, in accordance with the Semiconductor Equipment and Materials International (SEMI) standard. Examples of panels include glass substrates for liquid crystal panels and panels equipped with electronic components. The panel has a rectangular shape. Examples of panel sizes include 510 mm × 515 mm and 600 mm × 600 mm. The number of panels that can be stored in the panel storage container 1 is determined arbitrarily, and may be, for example, 6 panels, 12 panels, 16 panels, or 24 panels.

[0065] Panel storage container 1 is used, for example, in manufacturing equipment for electronic component assemblies. These assemblies are manufactured through the following steps: mounting numerous electronic components on a large carrier panel, such as a glass plate or stainless steel plate; sealing these electronic components with epoxy resin or the like; peeling the sealed electronic components from the carrier panel in panel form; and individually cutting the panel-shaped electronic components. Panel storage container 1 is used to transfer panels between these steps.

[0066] The panel storage container 1 includes a container body 2 and a lid 3 .

[0067] The container body 2 is a rectangular parallelepiped container with an open front surface. In other words, the container body 2 is a front open box type container with an opening 2a provided on the front surface. The container body 2 houses a plurality of panels. Specifically, the container body 2 houses the plurality of panels stacked vertically with spacing therebetween. Panels are removed from or placed into the container body 2 via the opening 2a. The container body 2 will be described in detail below.

[0068] The lid 3 is a member for closing the opening 2a of the container body 2. The lid 3 is detachably attached to the flange 25 defining the opening 2a. The details of the lid 3 will be described later.

[0069] The container body 2 and lid 3 can also be constructed by combining multiple parts formed from metal or resin materials. Examples of the resin contained in the resin forming material include thermoplastic resins. Examples of thermoplastic resins include polycarbonate, cycloolefin polymer, polyetherimide, polyetherketone, polyetheretherketone, polybutylene terephthalate, polyacetal, liquid crystal polymer, acrylic resins such as polymethyl methacrylate, and acrylonitrile butadiene styrene copolymer. Alloys of these resins can also be used as the resin contained in the resin forming material.

[0070] Conductive materials and various antistatic agents may also be added to these resins. Conductive materials include, for example, carbon fibers, carbon powder, carbon nanotubes, or conductive polymers. As antistatic agents, anionic, cationic, and nonionic antistatic agents may be used. Ultraviolet light absorbers such as benzotriazole, salicylate, cyanoacrylate, oxalic acid anilide, and hindered amine may also be added. Glass fibers or carbon fibers that increase rigidity may also be optionally added.

[0071] Next, the container body 2 will be described in detail. The container body 2 includes a top plate 21 , a bottom plate 22 , a pair of side walls 23 , a rear wall 24 , a flange 25 , and a frame 26 .

[0072] The top plate 21, bottom plate 22, side walls 23, and back wall 24 are rectangular plates. The top plate 21 and bottom plate 22 face each other vertically and are arranged substantially parallel to each other. The pair of side walls 23 face each other horizontally and are arranged substantially parallel to each other. The back wall 24 connects the rear ends of the top plate 21 and the rear ends of the bottom plate 22, as well as the rear ends of the pair of side walls 23. The top plate 21, bottom plate 22, pair of side walls 23, and back wall 24 define the storage space 20.

[0073] The top plate 21, bottom plate 22, and side walls 23 are made of, for example, a metal material such as aluminum or stainless steel. The back wall 24 is made of, for example, a transparent resin material that allows the storage space 20 to be viewed from outside the container body 2. A portion of the back wall 24 may also be made of a transparent resin material. Examples of transparent resin materials include acrylic resin, polycarbonate, vinyl chloride resin, and cycloolefin polymer.

[0074] The flange 25 is a rectangular frame extending across the front end of the top plate 21, the front end of the bottom plate 22, and the front ends of the pair of side walls 23. The flange 25 defines the opening 2a. The flange 25 is constructed, for example, from the aforementioned resin material or a metal material such as aluminum or stainless steel. Two upper locking holes 25h are provided in the upper and lower frame portions of the flange 25, spaced apart in the left-right direction. The upper locking holes 25h in the upper frame portion and the upper locking holes 25h in the lower frame portion are positioned so as to face each other in the vertical direction.

[0075] The frame 26 is used to fix the top plate 21, the bottom plate 22, the pair of side walls 23 and the back wall 24. The frame 26 is made of a metal material such as aluminum or stainless steel. The frame 26 is provided on the front surface of the back wall 24. The frame 26 has a frame portion 26a (see Figure 2 ), support 26b (refer to Figure 2 ), a pair of pillars 26c (refer to Figure 2 The frame portion 26 a is a rectangular member and is provided along the periphery of the rear wall 24 .

[0076] The support 26b and the pair of supports 26c are columnar members extending in the vertical direction. One support 26c, support 26b, and the other support 26c are arranged sequentially in the left-right direction and are substantially parallel to each other. The support 26b and the pair of supports 26c extend from the upper frame portion of the frame 26a to the lower frame portion. The support 26b is located at the center of the frame 26 in the left-right direction, and the pair of supports 26c are located near both ends of the frame 26 in the left-right direction. The support 26b is provided with multiple fitting holes for mounting the main shaft 61a, described later. The support 26c is provided with multiple fitting holes for mounting the main shaft 62a, described later.

[0077] Cover members are provided at corners of the container body 2 to prevent particles from entering the storage space 20 .

[0078] Next, refer to Figure 2 The internal structure of the container body 2 will be described. Figure 2 It is along Figure 1 The cross-sectional view of line II-II. Figure 2 As shown, the panel storage container 1 includes a plurality of support members 61 , a plurality of support members 62 , a plurality of side plates 63 and a plurality of retaining bodies 64 .

[0079] Each support member 61 is a portion for supporting the central portion of the panel in the left-right direction. Each support member 61 includes a main shaft 61a and a plurality of elastic bodies 61b. The main shaft 61a is a columnar (e.g., cylindrical) member extending in the front-to-back direction. The rear end of the main shaft 61a is fixed to a support 26b provided on the inner surface of the back wall 24. The main shaft 61a is made of, for example, a material with high bending rigidity. Examples of the material constituting the main shaft 61a include metals such as stainless steel and aluminum, and carbon fiber reinforced plastic.

[0080] Each elastic body 61b is an annular (for example, circular) component provided on the outer peripheral surface of the main shaft 61a around the axis of the main shaft 61a. Each elastic body 61b is provided to suppress the sliding of the panel and improve the positioning accuracy of the panel. Each elastic body 61b is made of, for example, a rubber material. Examples of rubber materials include EPDM (ethylene propylene diene monomer), silicone rubber, and fluorine rubber. A plurality of elastic bodies 61b are arranged at regular intervals along the extension direction of the main shaft 61a.

[0081] Each supporting member 62 is a portion for supporting the end portions of the panel in the left-right direction. Each supporting member 62 includes a main shaft 62a, a plurality of elastic bodies 62b, a stopper 62c, and a stopper 62d. The main shaft 62a is a columnar (e.g., cylindrical) member extending in the front-to-back direction. The rear end portion of the main shaft 62a is fixed to a support 26c provided on the inner surface of the back wall 24. The main shaft 62a is made of, for example, a material having high bending rigidity. Examples of the constituent materials of the main shaft 62a include metals such as stainless steel and aluminum, and carbon fiber reinforced plastics. The length of the main shaft 62a in the front-to-back direction is slightly longer than the length of the panel in the front-to-back direction, and is longer than the length of the main shaft 61a in the front-to-back direction.

[0082] Each elastic body 62b is an annular (e.g., circular) member disposed on the outer circumference of the main shaft 62a around its axis. Each elastic body 62b is provided to suppress panel slippage and improve panel positioning accuracy. The materials and arrangement of each elastic body 62b are identical to those of the elastic body 61b, and therefore a detailed description thereof will be omitted.

[0083] The stopper 62c is a member that prevents the panel from flying out and determines the position of the front end of the panel. The stopper 62c is made of, for example, the resin material described above. The stopper 62c is located at the front end of the main shaft 62a. The stopper 62d is a member that determines the position of the rear end of the panel. The stopper 62d is made of, for example, the resin material described above. The stopper 62d is located at the rear end of the main shaft 62a. The stopper 62d has a block-like shape. The stopper 62d is provided with an insertion hole for inserting the main shaft 62a in the front-to-back direction.

[0084] The number of support members 61 and 62 varies depending on the number of panels that can be stored in the panel storage container 1. In this embodiment, the panel storage container 1 includes one support member 61 and two support members 62 for each panel. In other words, one support member 61 and two support members 62 form a storage section for each panel. The one support member 61 and two support members 62 are arranged in the left-right direction. One support member 61 is positioned between the two support members 62.

[0085] Each side plate 63 is a member for mounting a retaining body 64. Each side plate 63 is a plate-shaped member extending in the vertical direction. Each side plate 63 is made of a metal material such as aluminum or stainless steel. Each side plate 63 is provided on the outer surface of the side wall 23. In this embodiment, two side plates 63 are provided on each side wall 23. The two side plates 63 are arranged in the front-to-back direction and are arranged substantially parallel to each other. One side plate 63 is provided near the center of the side wall 23 in the front-to-back direction, and the other side plate 63 is provided near the front end of the side wall 23 in the front-to-back direction.

[0086] Each retainer 64 is a member for retaining (supporting) the main shaft 62a and supporting the left-right ends of the panel. A through hole is provided at the front end of the retainer 64, extending through the retainer 64 in the front-back direction, and the main shaft 62a is inserted through the through hole.

[0087] The base end of retaining body 64 abuts against the inner surface of side wall 23, and positioning pins (not shown) are used to position side plate 63, side wall 23, and retaining body 64. In this position, screws are inserted through insertion holes provided in side plate 63 from the outside, and then screwed into threaded holes provided in the base end of retaining body 64. Thus, retaining body 64 is fixed to side plate 63 while side wall 23 is clamped between retaining body 64 and side plate 63.

[0088] Next, refer to Figure 1 and Figures 3 to 5 The cover 3 will be described in detail. Figure 3 It is from Figure 1 A perspective view of the cover as seen from the back. Figure 4 It is along Figure 3 Cross-sectional view along line IV-IV. Figure 5 It is along Figure 3 The cross-sectional view of the VV line. Figure 1 and Figures 3 to 5 As shown, the cover 3 includes a cover body 31 , a cover member 32 , a locking mechanism 33 and a sealing member 34 .

[0089] The cover body 31 is the main body of the cover body 3. The cover body 31 is a rectangular plate. The cover body 31 is made of a metal material such as aluminum or a magnesium alloy. The cover body 31 can also be made of a thermoplastic resin such as a polycarbonate resin. The cover body 31 has a front surface 31a (second surface) and a back surface 31b (first surface). The back surface 31b is the surface that faces the multiple panels in the front-to-back direction when the cover body 3 closes the opening 2a. The front surface 31a is the surface on the opposite side of the back surface 31b in the front-to-back direction.

[0090] A groove 35 for holding the sealing member 34 is provided on the back surface 31b. In the present embodiment, the groove 35 is arranged in an annular shape along the periphery of the back surface 31b, and is recessed from the back surface 31b to the front surface 31a. The groove 35 has a dovetail groove (undercut groove) structure. The groove 35 is defined by a side wall 51 (first side wall), a side wall 52 (second side wall) and a bottom wall 53. The side wall 51 and the side wall 52 (a pair of side walls) face each other in a direction intersecting the front-back direction. The bottom wall 53 connects the side wall 51 and the side wall 52.

[0091] In other words, bottom wall 53 is annularly arranged along the periphery of back surface 31b, and side walls 51 and 52 extend from both ends of bottom wall 53 toward back surface 31b. Side walls 51 and 52 have an annular shape that extends along the periphery of back surface 31b, facing each other with a predetermined distance between them. Front end 51a of side wall 51 and front end 52a of side wall 52 protrude toward each other, sandwiching groove 35.

[0092] The side wall 51 is provided with a plurality of through holes 51b (first space). Each through hole 51b is a space connected to the groove portion 35. Each through hole 51b penetrates the side wall 51 and has a long hole shape extending along the periphery of the back surface 31b. Each through hole 51b is arranged near the center of the length (height) of the side wall 51 in the front-to-back direction. The plurality of through holes 51b are arranged in a ring shape at certain intervals along the periphery of the back surface 31b. In other words, a plurality of through holes 51b are each provided in the upper part, lower part, left part and right part of the annular side wall 51. Through holes 51b can also be provided at the corner connecting the upper part and the left part, the corner connecting the upper part and the right part, the corner connecting the lower part and the left part, and the corner connecting the lower part and the right part.

[0093] The cover member 32 covers the front surface 31a of the cover body 31. The cover member 32 is a rectangular plate. The cover member 32 is made of a resin material such as polycarbonate. A keyhole 32h is provided in the cover member 32. A key (not shown) is inserted into the keyhole 32h.

[0094] The locking mechanism 33 locks and unlocks the lid 3 by operating a key inserted into the keyhole 32h. The locking mechanism 33 includes a latch (not shown). When the lid 3 is attached to the flange 25, the latch is engaged with the upper latch hole 25h provided in the flange 25 by operating the key, thereby locking the lid 3. When the lid 3 is locked, the latch is removed from the upper latch hole 25h by operating the key, thereby unlocking the lid 3.

[0095] The sealing member 34 is a member that seals the container body 2 and the lid body 31. The sealing member 34 is a rope-shaped elastic member. In the present embodiment, the sealing member 34 is arranged in a rectangular ring shape. The sealing member 34 is made of an elastically deformable resin. Examples of the resin include fluororubber, EPDM (ethylene propylene diene monomer), silicone, and urethane. In the present embodiment, a rubber sponge is used as the sealing member 34.

[0096] The sealing member 34 is provided on the back surface 31b of the cover body 31. Specifically, the sealing member 34 is embedded in the groove 35. The sealing member 34 has a volume larger than the volume of the groove 35. The sealing member 34 includes a protrusion 34a and a projection 34b (first projection).

[0097] The protrusion 34a is the portion that protrudes from between the front end portion 51a and the front end portion 52a toward the exterior of the groove portion 35. The front end surface of the protrusion 34a functions as a sealing surface. Specifically, the front end surface of the protrusion 34a is pressed against the stepped surface 25a of the flange 25, thereby airtightly sealing the opening 2a of the container body 2. The protrusion 34b is the portion that enters the through-hole 51b. By entering the through-hole 51b, the through-hole 51b is airtightly sealed. As a result, the cleanliness of the storage space 20 is maintained.

[0098] During the manufacturing process of the panel storage container 1, the sealing member 34 is inserted into the groove 35. As described above, the volume of the sealing member 34 is larger than the volume of the groove 35, and the sealing member 34 is elastically deformable. Therefore, when the sealing member 34 is inserted into the groove 35, the elastic force (restoring force) of the sealing member 34 causes a portion of the sealing member 34 to protrude from between the front end portion 51a and the front end portion 52a to form the protrusion 34a, while another portion of the sealing member 34 enters the through-hole 51b to form the protrusion 34b.

[0099] In the panel storage container 1 described above, the sealing member 34 is retained in the groove portion 35. On the side wall 51 of the groove portion 35, a through hole 51b connected to the groove portion 35 is provided, and the protrusion 34b of the sealing member 34 is provided in the through hole 51b. The through hole 51b extends in a direction intersecting with the direction (front direction) in which the groove portion 35 is recessed from the back surface 31b. Therefore, even if the sealing member 34 is subjected to a force in the direction (rear direction) in which it is disengaged from the groove portion 35, the protrusion 34b provided in the through hole 51b interferes with the side wall 51, so the sealing member 34 is not easily disengaged from the groove portion 35. As a result, the sealing member 34 can be held more firmly.

[0100] During the manufacturing process of the panel storage container 1, the through hole 51b is formed in the side wall 51 from its outer peripheral surface toward the groove 35. Therefore, the through hole 51b can be formed more easily than when a recess is formed in the inner peripheral surface of the side wall 51.

[0101] In addition, the panel storage container of the present disclosure is not limited to the above-described embodiment.

[0102] The connection method of each component of the container body 2 may be different from that in the above embodiment. In the above embodiment, the container body is formed by combining a plurality of parts, but it may also be an integrally molded product.

[0103] The number, size, and arrangement of the through holes 51b provided in the side wall 51 can be arbitrarily determined. The number of the through holes 51b provided in the side wall 51 may be one, or two or more.

[0104] like Figure 6 As shown in (a), multiple recesses 51c (first spaces) may be provided on the side wall 51 in place of the multiple through-holes 51b. Each recess 51c is a space connected to the groove 35. Each recess 51c is recessed in a direction away from the side wall 52. The number, size, and arrangement of the recesses 51c provided on the side wall 51 are the same as those for the through-holes 51b, and therefore their description is omitted. Alternatively, a single annular recess 51c may be provided around the entire circumference of the side wall 51.

[0105] In this modified example, a recess 51c connected to the groove 35 is provided on the side wall 51 of the groove 35, and the protrusion 34b of the sealing member 34 is arranged in the recess 51c. The recess 51c extends in a direction intersecting with the direction (front direction) in which the groove 35 is recessed from the back surface 31b. Therefore, even if the sealing member 34 is subjected to a force in the direction (rear direction) in which it is disengaged from the groove 35, the protrusion 34b provided in the recess 51c interferes with the side wall 51, so the sealing member 34 is not easily disengaged from the groove 35. As a result, the sealing member 34 can be held more firmly.

[0106] like Figure 6 As shown in (b), a plurality of recesses 52b (second spaces) can be provided on the side wall 52. Each recess 52b is a space connected to the groove portion 35. Each recess 52b is recessed in a direction away from the side wall 51. Each recess 52b is provided near the center of the front-to-back length (height) of the side wall 52. A plurality of recesses 52b are arranged in a ring shape at certain intervals along the periphery of the back surface 31b. That is, a plurality of recesses 52b are provided in each of the upper part, the lower part, the left part and the right part of the annular side wall 52. Recesses 52b can also be provided at the corners connecting the upper part and the left part, the corners connecting the upper part and the right part, the corners connecting the lower part and the left part, and the corners connecting the lower part and the right part.

[0107] The recess 52b can be provided at a position opposite to the through-hole 51b or at a position different from the position opposite to the through-hole 51b. The number, size, and arrangement of the recesses 52b provided on the side wall 52 can be arbitrarily determined. The number of recesses 52b provided on the side wall 52 can be one or two or more. Alternatively, a single annular recess 52b can be provided around the entire circumference of the side wall 52.

[0108] In this modification, the sealing member 34 further includes a protrusion 34c (second protrusion). The protrusion 34c is a portion that enters the recess 52b.

[0109] In the manufacturing process of the panel storage container 1 including the cover body 3 of this modified example, when the sealing member 34 is embedded in the groove 35, due to the elastic force (restoring force) of the sealing member 34, a part of the sealing member 34 protrudes from between the tip end 51a and the tip end 52a to form a protrusion 34a, another part of the sealing member 34 enters the through hole 51b to form a protrusion 34b, and another part of the sealing member 34 enters the recess 52b to form a protrusion 34c.

[0110] In this modified example, a through hole 51b connected to the groove portion 35 is provided on the side wall 51, and a recess 52b connected to the groove portion 35 is provided on the side wall 52. The protrusion 34b of the sealing member 34 is provided in the through hole 51b, and the protrusion 34c of the sealing member 34 is provided in the recess 52b. The through hole 51b and the recess 52b extend in a direction intersecting with the direction (front direction) in which the groove portion 35 is recessed from the back surface 31b. Therefore, even if the sealing member 34 is subjected to a force in the direction (rear direction) of disengagement from the groove portion 35, since the protrusion 34b provided in the through hole 51b will interfere with the side wall 51, and the protrusion 34c provided in the recess 52b will interfere with the side wall 52, it is more difficult for the sealing member 34 to disengage from the groove portion 35. As a result, the sealing member 34 can be held more firmly.

[0111] Furthermore, when the recess 52b is provided at a position opposite to the through hole 51b, the through hole 51b is formed in the side wall 51 from the outer peripheral surface of the side wall 51 toward the groove 35, and the recess 52b is formed in the side wall 52. Therefore, the through hole 51b and the recess 52b can be easily formed.

[0112] like Figure 6 As shown in (c), Figure 6 In the modified example shown in (a), a plurality of recesses 52b (second spaces) may be provided in the side wall 52. In this case, the sealing member 34 includes a protrusion 34c that enters the recess 52b.

[0113] like Figure 7 As shown, the side wall 52 can be provided with a plurality of through holes 52c (second spaces). Each through hole 52c is a space connected to the groove portion 35. Each through hole 52c penetrates the side wall 52. The number, size and configuration of the through holes 52c are the same as those of the recess 52b, so their description is omitted. In this modified example, the sealing member 34 further includes a protrusion 34c that enters the through hole 52c.

[0114] In this modified example, a through hole 51b connected to the groove portion 35 is provided on the side wall 51, and a through hole 52c connected to the groove portion 35 is provided on the side wall 52. The protrusion 34b of the sealing member 34 is provided in the through hole 51b, and the protrusion 34c of the sealing member 34 is provided in the through hole 52c. The through hole 51b and the through hole 52c extend in a direction intersecting with the direction (front direction) in which the groove portion 35 is recessed from the back surface 31b. Therefore, even if the sealing member 34 is subjected to a force in the direction (rear direction) in which it disengages from the groove portion 35, since the protrusion 34b provided in the through hole 51b will interfere with the side wall 51 and the protrusion 34c provided in the through hole 52c will interfere with the side wall 52, it is more difficult for the sealing member 34 to disengage from the groove portion 35. As a result, the sealing member 34 can be held more firmly.

[0115] The side wall 51 may not have the through hole 51b and the recess 51c, but may have the recess 52b (first space) or the through hole 52c (first space) on the side wall 52 (first side wall). In other words, it suffices to have a through hole or a recess on at least one of the side walls 51 and 52.

[0116] like Figure 8 As shown, a removal hole 53h can be provided in the bottom wall 53, extending through the cover body 31 (bottom wall 53) in the front-to-back direction. With this configuration, a rod-shaped member can be inserted into the removal hole 53h, thereby applying a force to the sealing member 34 in a direction to separate from the groove 35. This facilitates removal of the sealing member 34.
