Prevent rainwater from entering the space. As shown in FIGS. 4 and 5, the waterproof plate 9 is formed in a rectangular plate shape that is one size smaller than the frame body 35 of the body 3. The waterproof plate 9 is made of, for example, a soft vinyl chloride resin. An annular groove 91 is formed on the front surface of the waterproof plate 9. The groove 91 is formed so as to surround at least a region of the front surface of the waterproof plate 9 facing the second opening 362. By fitting the rib 352 formed on the rear surface of the frame body 35 into the groove 91, the intrusion of rainwater into the second opening 362 is prevented.

Further, a rib 92 is formed on the rear surface of the waterproof plate 9 so as to surround the region where the groove 91 is formed over substantially the entire circumference. The rib 92 prevents rainwater from entering the space between the waterproof plate 9 and the construction surface. Further, in the waterproof plate 9, a wire passage hole 93 for wiring is formed at a position corresponding to the second opening 362. In the waterproof plate 9, a pair of mounting holes 94 for passing mounting screws are formed at positions corresponding to the pair of mounting holes 353.

According to the above configuration, the wiring appliance device 10 is attached to the construction surface by a pair of mounting screws in a state where the body 3 holding the wiring appliance 4 is combined with the waterproof plate 9. At this time, the electric wire drawn from the construction surface is introduced into the internal space of the storage portion 36 through the through hole 93 and the second opening 362, and is connected to the terminal portion of the wiring fixture 4 in the storage portion 36. When the cover body 2 attached to the body 3 is closed, that is, when the cover body 2 is in the closed position, the pair of mounting screws are covered by the cover body 2 together with the wiring device 4.

(2.4) Details of Cover for Wiring Equipment Hereinafter, a more detailed configuration of the cover 20 according to the present embodiment will be described with reference to FIGS. 6 to 8B.

The cover main body 2 integrally has a first molded body 21 and a second molded body 22. The first molded body 21 is made of a first resin containing a bright pigment. The second molded body 22 is made of a second resin that does not contain a glittering pigment. In the present embodiment, the first molded body 21 and the second molded body 22 are integrally molded products integrally molded by two-color molding (double molding). The first molded body 21 has a main plate 210 and a first side plate. The 211 and the second side plate 212 are integrally provided. The main plate 210 covers the wiring device 4 from at least one of the front side and the upper side. The first side plate 211 is configured to project rearward from the left end edge of the main plate 210. That is, the first side plate 211 is adjacent to the main plate 210 and covers the wiring device 4 from the left side. The second side plate 212 is configured to project rearward from the right end edge of the main plate 210. That is, the second side plate 212 is adjacent to the main plate 210 and covers the wiring device 4 from the right side. At the center of the lower end of the main plate 210 in the left-right direction, an opening 213 having a shape open downward when viewed from the front is formed.

The second molded body 22 integrally has a bottom plate 23, a pair of vertical frame portions 24, a rising portion 25, and a reinforcing portion 26. The bottom plate 23 covers the wiring device 4 from below. The pair of vertical frame portions 24 project rearward from the rear end edges of each of the first side plate 211 and the second side plate 212. The pair of vertical frame portions 24 are provided over the entire length of the first molded body 21 in the vertical direction. As shown in FIG. 6, the rising portion 25 is formed so as to rise upward from the front end edge of the bottom plate 23 and both end edges in the left-right direction. The rising portion 25 includes an exposed portion 251 exposed forward through the opening 213. The portion of the rising portion 25 other than the exposed portion 251 is coupled to the first molded body 21 so as to overlap the first molded body 21 from the back surface (opposing surface to the body 3) side. The reinforcing portion 26 is a strip-shaped member that connects the rising portion 25 and the pair of vertical frame portions 24, and is overlapped with the first molded body 21 from the back surface (opposing surface to the body 3) side. It is combined with the first molded body 21.

In other words, with respect to the main wall portion 200, in the cover main body 2, only the central portion in the left-right direction at the lower end portion is composed of the second molded body 22 (exposed portion 251), and the other portions are the first molded body 21. It is composed of (main plate 210). Similarly, for the first side wall portion 201, only the rear end portion is composed of the second molded body 22 (vertical frame portion 24), and the other parts are formed of the first molded body 21 (first side plate 211). It is configured. Regarding the second side wall portion 202, only the rear end portion is composed of the second molded body 22 (vertical frame portion 24), and the other parts are composed of the first molded body 21 (second side plate 212). There is. The bottom wall portion 203 is composed of a second molded body 22 (bottom plate 23).

In the present embodiment, the first resin constituting the first molded body 21 is a flame-retardant resin containing a bright pigment. The term "brilliant pigment" as used herein is a pigment composed of, for example, metal powder (metal flakes), mica, titanium oxide, glass flakes, etc., and exhibits a metallic luster or a pearl-like luster. In the present embodiment, a metal powder (aluminum flakes as an example) is used as the brilliant pigment, and the first resin constituting the first molded body 21 is colored with a metallic color. That is, the first resin constituting the first molded body 21 is a so-called uncoated (raw material coloring) resin colored at the raw material stage before molding by containing a bright pigment in a base material made of a translucent resin. Is. By using this kind of uncoated resin, it is possible to realize coloring such as metallic color on the finished product (first molded body 21) even if it is unpainted (paintless). The base material of the first resin, which is a flame-retardant resin, is, for example, polycarbonate, ASA resin, PC / ABS alloy resin, ABS resin, or the like.

Further, the second resin constituting the second molded body 22 is a flame-retardant resin containing no bright pigment. In the present embodiment, the second resin constituting the second molded body 22 uses a so-called solid color uncoated resin which does not contain a bright pigment as a pigment but contains only a coloring pigment. By using this kind of uncoated resin, it is possible to realize solid color coloring on the finished product (second molded body 22) even if it is unpainted (paintless). The base material of the second resin, which is a flame-retardant resin, is, for example, polycarbonate, ASA resin, PC / ABS alloy resin, or ABS resin. In the present embodiment, the base material of the second resin is a resin different from the base material of the first resin.

Further, the "flammable resin" referred to in the present disclosure is a resin having flame retardancy rather than flammability when the flammability of the resin is classified into flammability and flame retardancy (including nonflammability). Is. In the present embodiment, the cover body 2 has a flame retardancy of UL94 V-2 or higher. "UL94" is a flame retardancy evaluation standard established by UL (Underwriters Laboratories). There are six UL94 standard grades: "HB" in the horizontal combustion test, "V-2", "V-1", "V-0", "5VA", and "5VB" in the vertical combustion test. There is a grade. These six grades have the lowest flame retardancy of "HB", and flame retardant in the order of "HB", "V-2", "V-1", "V-0", "5VB", and "5VA". The sex becomes high. That is, the cover main body 2 (first molded body 21 and second molded body 22) having a flame retardancy of UL94 V-2 or higher is "V-2", "V-1", except for "HB". It will have any flame retardancy of "V-0", "5VB" and "5VA". A resin having a flame retardancy of UL94 V-2 or higher has a property of burning in the atmosphere while being exposed to a flame, but extinguishing the fire when separated from the flame (self-extinguishing property). The flame-retardant resin used as the material of the cover body 2 (first molded body 21 and second molded body 22) has a flame retardancy of "V-2" or higher in the UL94 standard when the sample thickness is, for example, 2.5 mm. It is preferable to have sex.

Further, of the first molded body 21, at least one surface (that is, the surface) of each of the first side plate 211 and the second side plate 212 on the opposite side to the body 3 is an uneven surface that has been embossed (embossed). The "texture processing" referred to here is a process of forming a fine uneven wrinkle pattern (texture) on the surface of the first molded body 21 at the time of molding the first molded body 21. In the present embodiment, of the first molded body 21, the left side surface of the first side plate 211, the right side surface of the second side plate 212, and the front surface and the upper surface of the main plate 210 are textured uneven surfaces. As a result, even if the first molded body 21 is unpainted (paintless), it is possible to realize a texture similar to painting due to the fine irregularities on the surface.

Further, if the first molded body 21 has a silver-like metallic color and the second molded body 22 has a solid color such as gray or black, the first molded body 21 stands out as compared with the second molded body 22. Become. In particular, by adopting the same type of solid color as the second molded body 22 for the body 3, the hinge structure and the like provided at the rear end portion of the wiring fixture case 1 become less noticeable and sharp. Can achieve a nice appearance.

By the way, the cover main body 2 has at least one (four in this embodiment) through holes 27. All of these through holes 27 are provided in the second molded body 22 of the first molded body 21 and the second molded body 22. That is, all the through holes 27 are formed in the second molded body 22, and the through holes 27 are not formed in the first molded body 21. The "through hole" here means a hole formed so as to penetrate the second molded body 22 and the peripheral edge of the opening surface is formed in a closed loop shape. That is, a hole having a discontinuous peripheral edge of the opening surface, that is, a hole having a shape in which a part of the peripheral edge is open, such as the drawer portion 231, is not included in the “through hole” here.

As described above, since the through hole 27 is formed only in the second molded body 22 that does not contain the brilliant pigment, for example, even if a weld line is generated around the through hole 27, the weld line is inconspicuous. There are advantages. That is, when the cover main body 2 having the through hole 27 is molded by injection molding, for example, in the molding of the cover main body 2, a cavity formed between the plurality of mold pieces in a state where a plurality of mold pieces are combined is formed. The molten resin is injected into the inside from the gate portion. Here, the core for forming the through hole 27 becomes an obstacle and the molten resin splits into two hands, and the tips (flow fronts) of the split molten resin merge around the core to form a weld line. May occur. If such a weld line is generated in the first molded body 21, since the molten resin (first resin) contains a directional bright pigment, the weld line depends on the orientation state of the bright pigment. May be noticeable in appearance. On the other hand, in the second molded body 22 that does not contain the brilliant pigment, the colored pigment contained in the molten resin (second resin) has a substantially spherical shape and has no directionality, so that the weld line is inconspicuous in appearance.

In the present embodiment, the through hole 27 is provided only in the second molded body 22 of the first molded body 21 and the second molded body 22, and therefore, for the above reason, the molded cover body 2 penetrates. There is an advantage that the weld line around the hole 27 is inconspicuous.

The plurality of through holes 27 include an operation hole 271, a regulation hole 272, and a pair of bearing holes 273. In the present embodiment, all four through holes 27 are formed in the second molded body 22. The operation hole 271 is formed in the exposed portion 251 of the rising portion 25 in the second molded body 22. The regulation hole 272 is formed at the lower end of the vertical frame portion 24 of one of the pair of vertical frame portions 24 (on the right side in this embodiment) in the second molded body 22. The pair of bearing holes 273 are formed in the upper end portions (bearing portions 28) of the pair of vertical frame portions 24.

Further, in the present embodiment, the first molded body 21 does not have a uniform thickness over the entire body, but the thickness partially changes. Here, at least a part of the main plate 210 is set to have a larger thickness than the first side plate 211 and the second side plate 212.

Specifically, as shown in FIGS. 8A and 8B, the thickness t2 of the region Z1 corresponding to the curved portion 204 (see FIG. 2) of the main plate 210 is the other region (for example, the flat portion 205 (FIG. 2). The area corresponding to (see)) is larger than the thickness t1 (t1 <t2). The thickness t1 of the region corresponding to the flat surface portion 205 (see FIG. 2) of the main plate 210 is the same as the thickness t1 of the first side plate 211 and the second side plate 212. FIG. 8B is an enlarged view of a main part of the cross section taken along the line AA of FIG. Here, the thickness t1 of the first side plate 211, the second side plate 212, and the like is preferably 2 mm to 3 mm as an example. In this case, the thickness t2 of the region Z1 of the main plate 210 is preferably a value larger than the thickness t1 by, for example, a few percent to a dozen percent of the thickness t1.

In the present embodiment, as shown in FIG. 8A, the gate mark 214 of the first molded body 21 is located at the central portion in the left-right direction at the upper end portion of the main plate 210. Here, the gate mark 214 is provided on the rear surface of the main plate 210. The gate mark 214 is a portion that becomes an entrance of the resin when the resin (first resin) flows into the mold at the time of molding the first molded body 21, that is, a portion corresponding to the gate portion.

In such a configuration, the molten resin injected from the gate portion at the time of molding the first molded body 21 is basically in the mold for each of the main plate 210, the first side plate 211 and the second side plate 212. , Flows from the upper end to the lower end. Here, if the molten resin can reach the lower end portions of all of the main plate 210, the first side plate 211, and the second side plate 212 substantially at the same time, molding defects such as flow marks and weld lines are less likely to occur, which is ideal. However, the upper half (region Z1 corresponding to the curved portion 204) of the main plate 210 is curved, and the main plate 210 is from the upper end to the lower end as compared with the first side plate 211 and the second side plate 212. The distance becomes longer. In addition, due to various circumstances, the timing at which the molten resin reaches the lower end portion may vary between the main plate 210 and the first side plate 211 and the second side plate 212. For example, in the first side plate 211 and the second side plate 212, when the molten resin reaches the lower end portion before the main plate 210, the molten resin wraps around from the first side plate 211 and the second side plate 212 to the main plate 210, for example, a flow mark and a flow mark. Molding defects such as weld lines may occur.

Therefore, in the present embodiment, in the first molded body 21, at least a part of the thickness t2 of the main plate 210 is made relatively larger than the thickness t1 of the first side plate 211 and the second side plate 212. The flow velocity of the molten resin at the time of molding the molded body 21 is controlled. In short, if the thickness t2 of the main plate 210 is larger than the thickness t1 of the first side plate 211 and the second side plate 212, the flow velocity of the molten resin in the main plate 210 is improved. As a result, the timing at which the molten resin reaches the lower end can be aligned between the main plate 210 and the first side plate 211 and the second side plate 212, and molding defects such as flow marks and weld lines are less likely to occur.

Further, in the present embodiment, the gate mark 214 of the first molded body 21 is provided on the main plate 210, but the present invention is not limited to this example, and for example, the gate of the first molded body 21 is provided on the first side plate 211 and the second side plate 212. Traces may be provided.

(2.5) Details of Hinge Structure Next, a hinge structure for rotatably supporting the cover body 2 with respect to the body 3 will be described in detail with reference to FIGS. 9A to 12. FIG. 9A is a cross-sectional view of the upper end portion of the wiring fixture case 1 cut in a plane orthogonal to the front-rear direction when viewed from the front. 9B is an enlarged view of the region Z1 of FIG. 9A, and FIG. 9C is an enlarged view of the region Z2 of FIG. 9A.

The cover body 2 is supported by the body 3 by a hinge structure so as to be rotatable between a closed position and an open position about a rotation shaft 300 located at an upper end portion of the body 3. The hinge structure includes a support portion 32 of the body 3, a pair of bearing portions 28 of the cover main body 2, and a shaft body 7.

The shaft body 7 is a round bar-shaped member arranged on the rotating shaft 300. In this embodiment, the shaft body 7 is made of metal. On the outer peripheral surface of the shaft body 7, a recess 70 is formed in the central portion of the shaft body 7 in the axial direction over the entire circumference. Since the shaft body 7 is separate from the resin body 3 and the cover main body 2, the material of the shaft body 7 can be made of metal, and the shaft body 7 is made of resin while ensuring a certain level of strength. The diameter of the shaft body 7 can be made smaller than that of the shaft body of.

The support portion 32 has a holding hole 34 through which the shaft body 7 is passed. The holding hole 34 penetrates the support portion 32 along the axial direction (left-right direction) of the rotating shaft 300. The width of the support portion 32 in the left-right direction is smaller than the width of the body 3 in the left-right direction. The support portion 32 is an upper end portion of the body 3 and is provided at a central portion in the left-right direction of the body 3. In the present embodiment, the support portion 32 is arranged in the water passage groove 31 (see FIG. 10) formed in the body 3.

Specifically, a water passage groove 31 having an upper surface opening is formed at the upper end of the body 3 as described above. As shown in FIG. 10, the water passage groove 31 has a pair of side surfaces 311 facing each other in the front-rear direction. The water passage groove 31 is formed over substantially both ends in the left-right direction at the upper end portion of the body 3. Further, the bottom surface 312 of the water passage groove 31 is inclined with respect to the horizontal plane so as to be lowered toward both end edges in the left-right direction. As a result, water W1 (see FIG. 12) such as rainwater that has entered through the gap between the body 3 and the cover body 2 is guided to both left and right surfaces of the body 3 through the water passage groove 31.

The support portion 32 is located between the pair of side surfaces 311 of the water passage groove 31. The support portion 32 is located at the rear end portion in the water passage groove 31 so that a gap is formed between the pair of side surface 311s and the front side surface 311. Further, an opening connected to the holding hole 34 is provided in the central portion in the left-right direction on the rear surface of the support portion 32 (see FIG. 5). Here, the support portion 32 is formed so as to project upward from the bottom surface 312 of the water passage groove 31, but this configuration is not essential, for example, there is a gap between the bottom surface 312 and the support portion 32. You may.

The shaft body 7 is inserted into the holding hole 34. The width of the support portion 32 in the left-right direction is shorter than the total length of the shaft body 7, and both ends of the shaft body 7 project from the support portion 32 in a state where the shaft body 7 is inserted into the holding hole 34.

On the inner peripheral surface of the holding hole 34, a protrusion 340 is provided at a portion corresponding to the recess 70 of the shaft body 7 in a state where the shaft body 7 is inserted into the holding hole 34. By inserting the protrusion 340 into the recess 70, the shaft body 7 is positioned in the holding hole 34 in the axial direction (left-right direction) of the rotating shaft 300. That is, with the protrusion 340 inserted into the recess 70, the protrusion 340 comes into contact with the side surface 701 (see FIG. 9C) of the recess 70, so that the first orientation along the axial direction (left-right direction) of the rotating shaft 300 is reached. The protrusion 340 regulates the movement of the shaft body 7 to. In the present embodiment, the protrusion 340 comes into contact with the left side surface 701 of the left and right side surfaces of the recess 70 formed in the shaft body 7, so that the shaft body 7 to the right as the "first direction" Movement is restricted.

In the present embodiment, the direction in which the shaft body 7 is inserted into the holding hole 34 at the time of assembling the wiring device case 1 is determined. For example, the shaft body 7 moves from the right side to the left side of the holding hole 34. Will be inserted. Here, assuming that the direction opposite to the first direction (right side) is the "second direction", the shaft body 7 is inserted in the second direction (left side) with respect to the holding hole 34. It will be. The right end surface of the protrusion 340 is an inclined surface 341 (see FIG. 9C) inclined with respect to the axial direction of the rotating shaft 300. The inclined surface 341 is inclined so that the amount of protrusion 340 from the inner peripheral surface of the holding hole 34 becomes smaller as it approaches the right end edge. As a result, when the shaft body 7 is inserted into the holding hole 34 from the right side, the shaft body 7 comes into contact with the inclined surface 341 of the protrusion 340, so that the shaft body 7 can easily ride on the protrusion 340. Further, the left end surface of the protrusion 340 is a regulation surface 342 orthogonal to the rotation axis 300. Therefore, when the protrusion 340 is inserted into the recess 70, the regulation surface 342 comes into contact with the side surface 701 of the recess 70, thereby restricting the movement of the shaft body 7 in the first direction (to the right).

Further, the support portion 32 further has a plurality of convex portions 343 protruding from the inner peripheral surface of the holding hole 34 (see FIG. 9A). In the present embodiment, a pair of convex portions 343 are formed at both ends of the holding hole 34 in the left-right direction, slightly closer to the center portion. With the shaft body 7 inserted into the holding hole 34, the tips of the pair of convex portions 343 come into contact with the metal shaft body 7, so that the shaft body 7 is reduced in rattling. Is supported by the support portion 32. In order to reduce the rattling of the shaft body 7, the shaft body 7 may be knurled, but the knurling is expensive. In the present embodiment, by forming the convex portion 343 on the inner peripheral surface of the holding hole 34, it is possible to inexpensively realize a configuration for reducing the rattling of the shaft body 7.

The pair of bearing portions 28 are provided at both ends of the upper end portion of the cover main body 2 in the left-right direction. The pair of bearing portions 28 are located on both sides of the support portion 32 of the body 3 in the left-right direction. In the present embodiment, the pair of bearing portions 28 are formed at the upper end portions of the pair of vertical frame portions 24 of the second molded body 22. The pair of bearing portions 28 has a pair of bearing holes 273 through which the shaft body 7 is passed. The bearing hole 273 penetrates the bearing portion 28 along the axial direction (left-right direction) of the rotating shaft 300.

When the shaft body 7 is inserted into the holding hole 34 and the pair of bearing holes 273, the central piece 71 of the shaft body 7 is held by the support portion 32, and the tip piece 72 and the base end piece 73 of the shaft body 7 are paired. It is held by the bearing portion 28 of. The central piece 71 is a central portion of the shaft body 7 in the longitudinal direction (left-right direction). The tip piece 72 is a portion protruding from the central piece 71 in the second direction (left), and protrudes from the support portion 32 in the second direction (left). The tip piece 72 is held in the left bearing portion 28 by being inserted into the bearing hole 273 formed in the bearing portion 28 of one of the pair of bearing portions 28 (here, the left side). The base end piece 73 is a portion protruding from the central piece 71 in the first direction (right side), and protrudes from the support portion 32 in the first direction (right side). The base end piece 73 is held in the right bearing portion 28 by being inserted into the bearing hole 273 formed in the bearing portion 28 of one of the pair of bearing portions 28 (here, the right side). At least one of the support portion 32 and the pair of bearing portions 28 is configured to rotatably hold the shaft body 7 about the rotating shaft 300.

Here, as shown in FIG. 9B, the outer diameter d2 of the tip piece 72 is smaller than the outer diameter d1 of the central piece 71. Further, the inner diameter d3 of the bearing hole 273 on the left side into which the tip piece 72 is inserted is smaller than the outer diameter d1 of the central piece 71. Further, the inner diameter d3 of the bearing hole 273 on the left side into which the tip piece 72 is inserted is equal to or larger than the outer diameter d2 of the tip piece 72. That is, the relationship of "d2 ≦ d3 <d1" is established between the outer diameters d1 and d2 and the inner diameter d3 shown in FIG. 9B. In other words, a step is formed between the central piece 71 and the tip piece 72 on the outer peripheral surface of the shaft body 7 so that the outer diameter d2 of the tip piece 72 is smaller than the outer diameter d1 of the center piece 71. .. Further, the inner diameter of the bearing hole 273 on the right side into which the base end piece 73 is inserted is larger than the outer diameter d1 of the central piece 71. That is, the pair of bearing holes 273 have different inner diameters from each other.

Therefore, when the shaft body 7 is inserted in the second direction (left side) with respect to the holding hole 34 and the pair of bearing holes 273 at the time of assembling the wiring fixture case 1, the central piece 71 and the tip piece The step between 72 and 72 restricts the movement of the shaft body 7 in the second direction. That is, the shaft body 7 is inserted in the second direction (left) with the holding holes 34 and the pair of bearing holes 273 aligned in a straight line along the rotation shaft 300. At this time, after the tip piece 72 is inserted into the bearing hole 273 of the bearing portion 28 on the left side, the shaft body 7 has a step between the center piece 71 and the tip piece 72, and the bearing hole in the bearing portion 28 on the left side. Contact with the periphery of the 273 restricts movement in the second direction (to the left). In this state, the movement of the shaft body 7 in the first direction (to the right) is also restricted by the regulation surface 342 of the protrusion 340 coming into contact with the side surface 701 of the recess 70 as described above. .. Therefore, the movement of the shaft body 7 along the axial direction (left-right direction) of the rotating shaft 300 is restricted, and the shaft body 7 is prevented from coming off from the holding hole 34 and the pair of bearing holes 273.

As described above, since the shaft body 7 does not penetrate the bearing hole 273 on the left side of the pair of bearing holes 273, it is not an essential configuration to penetrate the bearing portion 28. That is, of the pair of bearing holes 273, the bearing hole 273 on one side (here, the left side) may be a hole having a bottom instead of the through hole 27.

Here, in the present embodiment, the inner diameters of the holding holes 34 and the pair of bearing holes 273 are both set to be equal to or larger than the outer diameter of the shaft body 7. Therefore, the shaft body 7 is press-fitted into the support portion 32 or the pair of bearing portions 28 while the shaft body 7 is positioned and prevented from coming off, as compared with the configuration in which the shaft body 7 is press-fitted into the support portion 32 or the pair of bearing portions 28. Damage can be reduced. Therefore, the wiring fixture case 1 is less likely to be damaged.

By the way, the wiring appliance case 1 according to the present embodiment includes a protruding piece 33 as a structure for holding (temporarily fixing) the cover main body 2 in an open position. The projecting piece 33 is provided on the body 3.

The protruding piece 33 has a cantilever shape. The projecting piece 33 projects from at least one of both end faces of the support portion 32 in the longitudinal direction (left-right direction) of the water passage groove 31. In the present embodiment, a pair of projecting pieces 33 are provided, and the pair of projecting pieces 33 project from both end faces of the support portion 32. As shown in FIG. 10, the pair of projecting pieces 33 are located below the shaft body 7 and are arranged so that the upper surface thereof faces the outer peripheral surface (lower surface) of the pair of bearing portions 28. Each of the pair of projecting pieces 33 is elastically deformable so that at least its tip portion moves in the vertical direction.

Each of the pair of projecting pieces 33 has a regulatory projection 331 projecting upward from its upper surface. The regulation protrusion 331 is formed in a substantially triangular shape having both sides in the front-rear direction as hypotenuses when viewed from one of the axial directions of the rotating shaft 300. On the other hand, each of the pair of bearing portions 28 has a hook portion 281 on a part of the outer peripheral surface of the cover body 2 in the rotation direction. The hook portion 281 is formed in a substantially triangular shape having both sides of the cover main body 2 in the rotation direction as hypotenuses when viewed from one of the axial directions of the rotation shaft 300. Here, the pair of restricting protrusions 331 in the pair of protruding pieces 33 are located around the rotation shaft 300 and on the locus of the hooking portion 281 when the cover main body 2 moves from the closed position to the open position. ..

In the state where the cover main body 2 is in the open position, the protruding piece 33 moves to the closed position of the cover main body 2 when a part of the protruding piece 33 (regulatory protrusion 331) comes into contact with the hooking portion 281 in the rotation direction of the cover main body 2. To regulate. That is, as shown in FIGS. 10 and 11, when the cover main body 2 is in the open position, a part of the protruding piece 33 (regulatory protrusion 331) provided on the body 3 is a part of the cover main body 2 (hooking portion 281). ), The movement (rotation) of the cover body 2 to the closed position is restricted. As a result, the cover body 2 is held in the open position.

Further, when the cover body 2 moves from the open position to the closed position, a part of the projecting piece 33 (regulating projection 331) is elastically deformed in a direction away from the rotation shaft 300 by being pushed by the hooking portion 281. Then, the restriction on the movement of the cover body 2 to the closed position is lifted. That is, when the user closes the cover main body 2 in the open position, as shown in FIG. 10, a part of the cover main body 2 (hooking portion 281) is a part of the protruding piece 33 of the body 3 (regulatory protrusion 331). By pressing, the protruding piece 33 is elastically deformed, and the tip portion of the protruding piece 33 moves downward. In FIG. 10, the tip end portion of the protruding piece 33 in a state of being moved downward is shown by an imaginary line (dashed-dotted line). As a result, the hooking portion 281 of the cover main body 2 gets over a part of the protruding piece 33 (regulatory protrusion 331), and the cover main body 2 can move to the closed position. In FIG. 10, the cover main body 2 after the hooking portion 281 has passed over the regulation protrusion 331 and before reaching the closed position is shown by an imaginary line (two-dot chain line). When the cover body 2 reaches the closed position, the hooking portion 281 is separated from the regulation protrusion 331, so that the protruding piece 33 returns to the original position (the position shown by the solid line in FIG. 10) due to its elastic force. When the cover main body 2 is in the closed position, the hook portion 281 is accommodated in the hole formed in the body 3 to avoid interference with the body 3.

When the cover body 2 moves from the closed position to the open position, as in the case where the cover body 2 moves from the open position to the closed position, a part (regulatory protrusion 331) of the protruding piece 33 is a hook portion 281. It is elastically deformed in the direction away from the rotating shaft 300 (downward). As a result, the cover body 2 can move to the open position, and when it reaches the open position, it is held in the open position.

By the way, in the state where the cover main body 2 is held in the open position, the body 3 receives the moment acting on the cover main body 2 due to the weight of the cover main body 2 by the protruding piece 33. Therefore, the elastic modulus of the projecting piece 33 is set to be relatively large so that the restriction on the movement of the cover body 2 to the closed position is not lifted by the moment acting on the cover body 2 due to the weight of the cover body 2. Is preferable. In this case, when the hooking portion 281 gets over the regulation protrusion 331, the protruding piece 33 is less likely to bend. Therefore, the shaft body 7 is elastic so that the shaft body 7 elastically deforms when the hooking portion 281 gets over the regulation protrusion 331. It is preferable to have. As a result, when the hooking portion 281 gets over the regulation protrusion 331, both the protruding piece 33 and the shaft body 7 are bent, and the decrease in the bending amount of the protruding piece 33 can be compensated for.

Further, in the present embodiment, as shown in FIG. 12, the hooking portion 281 is provided at a position facing the tip end portion of the protruding piece 33. As a result, when the hooking portion 281 gets over the regulation protrusion 331, the hooking portion 281 pushes the tip end portion of the protruding piece 33, so that the hooking portion 281 pushes the base end portion of the protruding piece 33, as compared with the case where the hooking portion 281 pushes the base end portion of the protruding piece 33. The protruding piece 33 tends to bend.
