[0018] The aroma lamp of the present disclosure is configured to heat an aromatic material to diffuse the aroma and also to create a visual effect using light. The aroma lamp of the present disclosure allows the user to enjoy various aromas depending on the type of aromatic material, and the aroma effects can provide the user with various effects such as a relaxing effect and a refreshing effect. Furthermore, by allowing the user to enjoy both the aroma and the light at the same time, various effects such as a relaxing effect and a refreshing effect can be effectively provided to the user.

[0019] The aromatic material may be solid or liquid. Examples of aromatic liquids include essential oils and aroma oils. Solid aromatic materials include natural materials that exist in nature and emit fragrance, such as herbs, nuts, fragrant woods such as agarwood and sandalwood, wood chips made by finely chipping cypress, birch, cherry, and pine, tea leaves such as Japanese tea and black tea, and coffee beans, as well as materials impregnated with aromatic liquids such as essential oils and aroma oils extracted from natural materials such as plants, such as cloth, dried flowers, or porous materials. It is preferable to use natural materials as the aromatic material.

[0020] Aromatic liquids are refined by extracting aromatic components from natural materials, etc., but because some aromatic components are removed during the refining process, aromatic liquids and aromatic materials impregnated with aromatic liquids may not be able to diffuse the original scent of the natural materials. By using natural materials in aromatic materials, the aromatic components inherent in the natural materials can be diffused as they are, allowing users to enjoy the original scent of the natural materials. The aromatic materials are not particularly limited, but are preferably natural materials that emit fragrance at low temperatures, for example, about 60°C to 90°C, such as cinnamon, cardamom, and peppermint.

[0021] Hereinafter, an embodiment of an aroma lamp according to the present disclosure will be described with reference to the accompanying drawings.

[0022] 1 to 4 show an aroma lamp 1 according to one embodiment of the present disclosure. Aroma lamp 100 comprises an aroma unit 101 that diffuses a fragrance and a light-emitting unit 102 that diffuses light. Aroma unit 101 is located at the top of aroma lamp 100, and light-emitting unit 102 is located at the bottom of aroma lamp 100, with light-emitting unit 102 located below aroma unit 101. Aroma lamp 100 further comprises a handle 9 that is held by a user's hand when carrying aroma lamp 100.

[0023] <Explanation of the light-emitting part> 2 and 4, the aroma lamp 100 includes, as a light-emitting unit 102, a light source unit 5 and a lampshade 6 that encompasses the light source unit 5. The aroma lamp 100 is configured such that light is emitted from the light source unit 5 and passes through the lampshade 6, thereby diffusing the light into the external space.

[0024] The heavy lampshade 6 of the aroma lamp 100 is located at the bottom of the aroma lamp 100, and the center of gravity of the aroma lamp 100 is at the bottom. This reduces the burden on the user when they grasp the handle 9 and lift the aroma lamp 100, and also allows the aroma lamp 100 to be placed stably.

[0025] In addition, when a user carries the aroma lamp 100 by holding the handle 9, the handle 9 swings, and the heavy lampshade 6 is located at the bottom of the aroma lamp 100, so that the center of gravity of the aroma lamp 100 is at the bottom, preventing the container 1 placed on the installation part 3 from tilting. This prevents the aromatic material placed in the container 1 from spilling out of the container 1.

[0026] <Lampshade explanation> As shown in FIG. 10 , the lampshade 6 has the shape of a hollow, bottomed housing that can accommodate the light source unit 5 and the control unit 7 that controls the lighting operation of the light source unit 5. An opening is provided at the top of the lampshade 6 for inserting the light source unit 5 and the control unit 7 into the lampshade 6. The material of the lampshade 6 is not particularly limited as long as it is translucent and allows light to pass through. The lampshade 6 may be transparent or translucent, and may be colored, such as milky white or white, or may be colorless. The lampshade 6 can be made of, for example, glass, resin, ceramics, etc.

[0027] In the illustrated example, the lampshade 6 has a bottle shape and is composed of a cylindrical body 60 with a bottom that can accommodate the light source unit 5, the control unit 7, etc., and a cylindrical neck 61 that is integrally formed with the body 60. The body 60 forms the lower part of the lampshade 6, and the neck 61 forms the upper part of the lampshade 6. The neck 61 is formed to be slightly smaller than the body 60. The neck 61 is formed with two recesses 62 that are recessed inward on both the inner and outer surfaces. The two recesses 62 extend along the circumferential direction of the neck 61 and are formed at positions that face each other in the circumferential direction of the neck 61.

[0028] <Explanation of the light source> 2, 4, and 9, the light source unit 5 is not particularly limited as long as it emits light under the control of the control unit 7, and can be configured with various lighting fixtures such as LED lights using light-emitting diodes, incandescent lamps, fluorescent lamps, etc. In the illustrated example, the light source unit 5 includes a plurality of small LED lights 50.

[0029] The LED lights 50 are attached to a cylindrical casing 51. The casing 51 has, for example, a cylindrical shape with a polygonal cross section, and a plurality of side surfaces 52 are connected in the circumferential direction of the casing 51. Each side surface 52 of the casing 51 extends from near the upper end to near the lower end of the body 60 of the lampshade 6, and each side surface 52 has a plurality of LED lights 50 arranged at intervals in the vertical direction. In other words, the light source unit 5 has a structure in which a plurality of LED lights 50 are arranged at intervals in the vertical direction, and a plurality of rows of these LED lights 50 arranged in the vertical direction are arranged at intervals in the circumferential direction. This allows light to be diffused into the external space by passing through the entire lampshade 6, not just a portion of the lower or upper part of the lampshade 6. Furthermore, since a shadow is not formed between the lights emitted from adjacent LED lights 50 and the center of the light of each LED light 50 is not visible through the light, and uniform light without spots is emitted from the plurality of LED lights 50, the entire lampshade 6 can be illuminated beautifully.

[0030] The multiple LED lights 50 may all emit light of the same color, or may all emit light of different colors, or may be color-coded into predetermined groups, with some emitting light of the same color, some emitting light of another same color, and the rest emitting light of yet another same color.

[0031] For example, the multiple LED lights 50 may be configured to include some that emit white light and others that emit orange light, and the LED lights 50 adjacent above and below the white light-emitting LED light 50, as well as the LED lights 50 adjacent on both the left and right sides in the circumferential direction of the white light-emitting LED light 50, may be configured to emit orange light. By controlling the lighting operation of the multiple orange LED lights 50 so that the LED lights 50 adjacent above, below, and on both the left and right sides in the circumferential direction alternately emit light, it is possible to achieve lighting that resembles the flickering of a candle flame, and to provide the user with a soothing light effect.

[0032] 1 to 4 and 7 to 9, the head 30 constituting the installation unit 3, which will be described later, is provided with a light-emitting switch 53 for setting the light emission intensity of each LED light 50. In the illustrated example, the light-emitting switch 53 is configured as a rotatable knob, and by rotating the knob, the user can turn each LED light 50 on / off and adjust the brightness. The lighting operation of each LED light 50 is controlled by the control unit 7.

[0033] <Explanation of the aromatic part> 1 to 5, aroma lamp 100 includes, as fragrance unit 101, container 1 as a storage unit for storing solid aromatic materials, lid 2 detachably attached to container 1, installation unit 3 in which container 1 is detachably installed, and heater 4 that heats container 1 installed in installation unit 3 from below. Aroma lamp 100 is configured so that the aromatic materials stored in container 1 and lid 2 are heated by heater 4 to emit a fragrance, and the fragrance passes through lid 2, diffusing the fragrance into the external space.

[0034] <Container description> 1 to 5, the container 1 is located at the top of the aroma lamp 100 and is exposed to the outside. In other words, the opening for the aromatic material in the storage section where the aromatic material is stored is exposed to the outside. This makes it easy to put the aromatic material into the container 1 and remove the used aromatic material from the container 1.

[0035] In the illustrated example, the container 1 is removable from the installation section 3 of the aroma lamp 100, so that the container 1 can be removed from the aroma lamp 100 and placed within reach of the user. This allows the container 1 to be cleaned if it becomes dirty, facilitating maintenance. In addition, while the container 1 can be placed in the installation section 3 and the used aromatic material can be removed from the container 1, placing the container 1 within reach of the user makes tasks such as replacing the aromatic material even easier.

[0036] The container 1 is made of a material with good thermal conductivity. The container 1 is preferably made of a metal such as aluminum or copper. A metal container 1 has a glossy surface and a beautiful appearance, which can improve the design of an aroma lamp 100 equipped with a metal container 1. The container 1 can also be made of materials other than metal, such as heat-resistant resin, ceramics, pottery, or stoneware.

[0037] 11 to 15, the container 1 comprises a bottom portion 10 on which the aromatic material is placed, a peripheral portion 11 rising from the outer periphery of the bottom portion 10, a flange portion 12 protruding outward from the upper edge of the peripheral portion 11, and a surrounding wall portion 13 rising from the outer periphery of the flange portion 12. The container 1 has a circular shape in a plan view, but the shape of the container 1 can be variously formed to match the shape of the installation portion 3, which will be described later.

[0038] The bottom portion 10 is plate-shaped with flat upper and lower surfaces. A solid aromatic material is placed on the upper surface of the bottom portion 10. When the container 1 is placed on the placement portion 3, the bottom portion 10 is placed on a heater plate 40 constituting the heater 4 described below, and the lower surface of the bottom portion 10 contacts the upper surface of the heater plate 40 (see FIG. 5). Because the lower surface of the bottom portion 10 is flat and a large contact area with the heater plate 40 can be secured, the aromatic material placed on the bottom portion 10 can be efficiently heated by the heater plate 40.

[0039] The peripheral portion 11 has a wall shape that is perpendicular to the bottom portion 10 or that slopes outward. The peripheral portion 11 surrounds the fragrance material placed on the bottom portion 10 and holds it on the bottom portion 10.

[0040] The flange portion 12 is plate-shaped with a flat bottom surface and a curved top surface. When the container 1 is placed on the installation unit 3, the flange portion 12 is placed on a support portion 33 located around the heater plate 40 in the installation unit 3, which will be described later, and the bottom surface of the flange portion 12 contacts the top surface of the support portion 33 (see FIG. 5).

[0041] The upper surface of the flange portion 12 is composed of an inner inclined surface 120 that slopes upward relative to the horizontal direction and an outer horizontal surface 121. When the lid 2 is attached to the container 1, legs 21 that form the outer peripheral edge of the lid 2, which will be described later, are placed on the horizontal surface 121 of the flange portion 12 (see FIG. 13 ). When the lid 2 is attached to the container 1, it is placed on the flange portion 12 that surrounds the bottom surface 10 of the container 1. The bottom surface 10 of the container 1 is the part that is heated by the heater 4, but when the lid 2 is placed on the bottom surface 10, heat applied to the bottom surface 10 is easily conducted to the lid 2, and the heat is easily dissipated from the bottom surface 10. This reduces the heating efficiency of the aromatic material placed on the bottom surface 10. By placing the lid 2 on the flange portion 12 that surrounds the bottom surface 10 of the container 1, it is possible to prevent heat applied to the bottom surface 10 from dissipating to the lid 2. This allows efficient heating of the aromatic material placed on the bottom surface portion 10. In addition, the natural material does not smell burnt due to low-temperature heating, and the fragrance can be continuously released while maintaining its strength.

[0042] The surrounding wall 13 has a wall shape that is perpendicular to the horizontal surface 121 of the flange 12. When the lid 2 is attached to the container 1, the surrounding wall 13 surrounds the lid 2 placed on the horizontal surface 121 of the flange 12 and holds it on the flange 12 (see FIG. 13). This allows the lid 2 to be placed stably on the container 1.

[0043] The container 1 is provided with a handle 14 that the user can grasp with their hand when carrying the container 1, such as when placing the container 1 on the installation unit 3 or removing the container 1 from the installation unit 3. The handle 14 is formed so as to protrude upward from the container 1. The handle 14 can be formed, for example, in a "U" shape or a "C" shape, and can be formed integrally with the container 1 by fixing both ends to the container 1 by welding or the like.

[0044] The handle 14 can be formed on the bottom 10, flange 12, or surrounding wall 13 of the container 1, but is preferably formed on the flange 12 or surrounding wall 13 that is farthest from the bottom 10, and more preferably on the surrounding wall 13 that is farthest from the bottom 10. In the illustrated example, both ends of the handle 14 are fixed to the upper surface of the surrounding wall 13 of the container 1. The bottom 10 of the container 1 is the part that is heated by the heater 4, but if the handle 14 is formed on the bottom 10, heat applied to the bottom 10 will be easily conducted to the handle 14, and the heat will easily escape from the bottom 10. This reduces the heating efficiency of the aromatic material placed on the bottom 10. For example, compared to heating an aromatic material with a candle flame, heating an aromatic material with heater plate 40 requires that the aromatic material be heated at a relatively low temperature (approximately 60°C to 90°C), and therefore the heat applied to bottom portion 10 must be efficiently transferred to the aromatic material. As shown in the illustrated example, by forming handle 14 on a part of container 1 away from bottom portion 10, it is possible to prevent the heat applied to bottom portion 10 from escaping to handle 14, and the aromatic material placed on bottom portion 10 can be efficiently heated. In addition, low-temperature heating prevents the natural material from developing a burnt smell, and the fragrance can be continuously released while maintaining its strength.

[0045] <Explanation of the lid> As shown in Figures 1 to 5 and 11 to 13, the lid 2 is removably attached to the container 1. When the lid 2 is attached to the container 1, it covers the aromatic material on the bottom surface 10 of the container 1. This traps heat applied to the bottom surface 10 of the container 1 in the space between the container 1 and the lid 2, making it less likely to escape to the outside space, thereby efficiently heating the aromatic material placed on the bottom surface 10. In the illustrated example, the lid 2 is attached to the container 1 simply by placing it over the container 1, and is removed from the container 1 simply by lifting it up from the container 1.

[0046] The lid 2 is preferably made of metal like the container 1, which improves the design of the aroma lamp 100. The lid 2 can also be made of materials other than metal, such as heat-resistant resin, ceramics, earthenware, or stoneware.

[0047] As shown in Figures 11 to 13 and Figures 16 to 17, the lid 2 includes a top surface 20 and legs 21 formed on the outer periphery of the top surface 20. The top surface 20 has a circular plate shape in a plan view. One or more diffusion holes 22 are formed in the top surface 20. The diffusion holes 22 are through-holes that penetrate the top surface 20 in the thickness direction and serve to widely disperse the scent diffused by heating the aromatic material into the external space. It is preferable that the top surface 20 has multiple small diffusion holes 22 formed uniformly scattered over a wide area. This prevents heat applied to the bottom surface 10 of the container 1 from escaping to the external space through the diffusion holes 22, while facilitating the transmission of the scent emitted from the aromatic material to the external space through the diffusion holes 22.

[0048] In a vertical cross section, the top surface 20 has a shape that rises higher at the center than at the outer periphery. In the illustrated example, the top surface 20 is curved in an upwardly convex dome shape, and when the lid 2 is attached to the container 1, the center of the lid 2 in a plan view becomes the part that is farthest from the bottom surface 10 of the container 1.

[0049] The top surface 20 is provided with a handle 23 that the user can grasp with their hand when carrying the lid 2, such as when attaching the lid 2 to the container 1 or removing the lid 2 from the container 1. The handle 23 is formed to protrude upward from the top surface 20. The handle 23 can be formed, for example, in a "U" shape or a "C" shape, and can be formed integrally with the lid 2 by fixing both ends to the top surface 20 by welding or the like.

[0050] The handle 23 can be formed at any part of the top surface 20, but is preferably formed at the center of the top surface 20, which is the highest point and farthest from the bottom surface 10 of the container 1. The bottom surface 10 of the container 1 is the part heated by the heater 4. If the handle 23 is formed on the lid 2 in a part close to the bottom surface 10 of the container 1, heat applied to the bottom surface 10 will be easily conducted to the handle 23 of the lid 2, and the heat will be more likely to escape from the bottom surface 10. This reduces the heating efficiency of the aromatic material placed on the bottom surface 10. As shown in the illustrated example, by forming the handle 23 on the lid 2 in a part farthest from the bottom surface 10 of the container 1, the heat applied to the bottom surface 10 can be prevented from escaping to the handle 23 of the lid 2, allowing the aromatic material placed on the bottom surface 10 to be efficiently heated. In addition, the natural material will not develop a burnt smell due to low-temperature heating, and the fragrance can be continuously released while maintaining its strength.

[0051] The top surface portion 20 is not limited to the curved plate shape described above, and may be, for example, a flat plate shape.

[0052] The legs 21 are annular protrusions with a predetermined width that hang down from the outer periphery of the top surface 20. The lower surfaces of the legs 21 are flat. The lid 2 is attached to the container 1 by placing the legs 21, which form the outer periphery, on the container 1.

[0053] <Explanation of the first protrusion> As shown in Figures 12 to 13 and Figures 16 to 17, at least one protrusion 24 (hereinafter referred to as "first protrusion 24") facing vertically is provided on the leg 21 of the lid 2 or on the flange 12 of the container 1, which is the portion on which the leg 21 of the lid 2 is placed. A protrusion facing vertically means that the protrusion extends in the up-down direction perpendicular to a horizontal plane. In the illustrated example, the first protrusion 24 is formed on the underside of the leg 21 of the lid 2 so as to protrude downward. Note that when the first protrusion 24 is provided on the flange 12 of the container 1, the first protrusion 24 is formed on the horizontal plane 121 outside the flange 12 so as to protrude upward.

[0054] Preferably, three or more first protrusions 24 are formed on the underside of the leg portion 21 of the lid 2 or on the outer horizontal surface 121 of the flange portion 12 of the container 1, and more preferably, the three or more first protrusions 24 are formed at uniform intervals in the circumferential direction. This allows the lid 2 to be stably placed on the container 1. When the lid 2 is placed on the container 1, the first protrusions 24 are interposed between the leg portion 21 of the lid 2 and the flange portion 12 of the container 1, preventing the underside of the leg portion 21 and the outer horizontal surface 121 of the flange portion 12 from coming into surface-to-surface contact. This prevents heat applied to the bottom surface 10 of the container 1 from escaping from the flange portion 12, which contacts the lid 2 on the container 1, to the lid 2, thereby efficiently heating the aromatic material placed on the bottom surface 10. In addition, the natural material does not develop a burnt odor due to low-temperature heating, and the fragrance is continuously released while maintaining its strength.

[0055] <Explanation of the second protrusion> The lid 2 is attached to the container 1 by placing the legs 21 forming the outer peripheral edge on the container 1, and as shown in Figures 11 to 14, the legs 21 of the lid 2 or the surrounding wall 13 of the container 1 that surrounds the legs 21 of the lid 2 are provided with at least one protrusion 15 (hereinafter referred to as "second protrusion 15") that faces horizontally. A protrusion facing horizontally means that the protrusion extends in a direction parallel to the horizontal plane. In the illustrated example, the second protrusion 15 is formed on the inner surface of the surrounding wall 13 of the container 1 so as to protrude inward. Note that when the second protrusion 15 is provided on the legs 21 of the lid 2, the second protrusion 15 is formed on the outer surface of the legs 21 so as to protrude outward.

[0056] Preferably, two or more second protrusions 15 are formed on the outer surface of the leg portion 21 of the lid 2 or the inner surface of the surrounding wall portion 13 of the container 1, and more preferably, the two or more second protrusions 15 are formed at uniform intervals in the circumferential direction. This allows the lid 2 to be stably placed on the container 1. When the lid 2 is placed on the container 1, the second protrusions 15 are interposed between the leg portion 21 of the lid 2 and the surrounding wall portion 13 of the container 1, preventing the outer surface of the leg portion 21 from coming into surface contact with the inner surface of the surrounding wall portion 13. This prevents heat applied to the bottom portion 10 of the container 1 from escaping from the surrounding wall portion 13 that contacts the lid 2 to the lid 2, allowing the aromatic material placed on the bottom portion 10 to be efficiently heated. In addition, the natural material does not develop a burnt smell due to low-temperature heating, and the fragrance can be continuously released while maintaining its strength.

[0057] <Installation section description> As shown in Figures 1 to 5 and 7 to 9, the container 1 is detachably mounted on the mounting part 3. The aroma lamp 100 includes, as the mounting part 3, a head 30 attached to a neck part 61 forming the upper part of the lampshade 6. The head 30 is not particularly limited, but is preferably made of a material that is thermally insulating and has lower thermal conductivity than the metal that is the material of the container 1 and the lid 2. The head 30 can be made of, for example, a synthetic resin, but can also be made of materials other than synthetic resin, such as ceramics, pottery, or wood.

[0058] As shown in Figures 5, 7, and 8, the head 30 comprises a top surface 31 with an opening formed in the center, and a cylindrical peripheral surface 34 hanging down from the outer periphery of the top surface 31. A heater plate 40 constituting the heater 4 is disposed in the central opening of the top surface 31. The head 30 has a circular shape in a plan view, but the shape of the head 30 is not particularly limited and can be various shapes. The central opening of the top surface 31 has a circular shape in a plan view, but the shape of the opening is not particularly limited and can be various shapes.

[0059] The top surface portion 31 is annular and plate-shaped with a predetermined width. The top surface portion 31 includes a base portion 32 on the outer periphery side and a support portion 33 on the central opening side. The upper surface of the base portion 32 is located higher than the upper surface of the support portion 33, and the boundary between the base portion 32 and the support portion 33 is stepped. The support portion 33 is located around the heater plate 40. In the illustrated example, the lower surface of the bottom portion 10 of the container 1 contacts the upper surface of the heater plate 40, and the flange portion 12 of the container 1 is placed on the support portion 33 of the head 30, thereby installing the container 1 on the head 30, which constitutes the installation portion 3. The flange portion 12 and surrounding wall portion 13 of the container 1 fit inside the base portion 32 of the top surface portion 31, allowing the container 1 to be stably installed on the head 30, which constitutes the installation portion 3. Furthermore, because the head 30 forming the mounting portion 3 has thermal insulation properties, it is possible to prevent heat applied to the bottom portion 10 of the container 1 from escaping from the flange portion 12 to the mounting portion 3. This allows for efficient heating of the aromatic material placed on the bottom portion 10. In addition, the natural material does not develop a burnt smell due to low-temperature heating, and the fragrance can be continuously released while maintaining its strength.

In the illustrated example, the head 30 is attached to the lampshade 6 so that the upper end of the neck portion 61 of the lampshade 6 abuts against the step 36 of the peripheral surface portion 34 and the lower portion 35B of the peripheral surface portion 34 surrounds the neck portion 61 of the lampshade 6.

[0061] 6, mounting portions 37 are formed on the lower portion 35B of the peripheral surface portion 34 to attach fasteners 8 that fix the head 30 to the neck portion 61 of the lampshade 6. In the illustrated example, two mounting portions 37 are formed at positions facing each other in the circumferential direction of the neck portion 61.

[0062] <Fastener Description> 1 to 9, the fastener 8 is not particularly limited as long as it can secure the head 30 to the neck portion 61 of the lampshade 6. In the illustrated example, the fastener 8 is configured to secure the head 30 to the neck portion 61 of the lampshade 6 and to arrange the handle 9 rotatably around the head 30. As shown in FIG. 6, the fastener 8 includes a latch 80, a fixing member 81, a ring 82, a washer 83, and a cap 84. The handle 9 can be made of wood, for example, but can also be made of materials other than wood, such as metal, resin, ceramics, leather, etc.

[0063] The latch 80 includes a base 85 that is annular and plate-like and has a predetermined thickness, and a pair of opposing protrusions 86 that protrude from one surface of the base 85. The latch 80 is attached to the attachment portion 37 so that the base 85 is disposed inside the circumferential surface 34 of the head 30 and the pair of protrusions 86 extend outside the circumferential surface 34, passing through the circumferential surface 34.

[0064] The fixing device 81 may be a screw, a bolt, or the like, and in the illustrated example, a set screw is used. The fixing device 81 is fixed to the mounting part 37 by fitting into a screw hole 38 formed in the mounting part 37. The tip of the fixing device 81 penetrates the base 85 of the latch 80 and abuts against the recess 62 in the neck part 61 of the lampshade 6. The head 30 is fixed to the neck part 61 of the lampshade 6 by clamping and supporting the neck part 61 of the lampshade 6 from multiple directions with the multiple fixing devices 81 fixed to the mounting part 37.

[0065] In the illustrated example, the tips of the fasteners 8 abut against recesses 62 formed in the neck portion 61 of the lampshade 6, so that the head 30 can be stably fixed to the neck portion 61 of the lampshade 6 by the multiple fasteners 8.

[0066] The ring 82 is installed on the mounting part 37 so that a part of it fits inside the recess 39 formed in the outer surface of the neck part 61 of the lampshade 6 and a part of it protrudes outward from the recess 39. The washer 83 is placed on the end of the ring 82 that protrudes from the recess 39.

[0067] The cap 84 comprises a disk-shaped cover portion 87 having a predetermined thickness, and an annular wall portion 88 that protrudes from one side of the cover portion 87 at a position inward from the outer periphery. A female thread is formed on the inner surface of the annular wall portion 88, and by fitting with a male thread formed on the outer surface of a pair of protrusions 86 of the latch 80, the cap 84 is integrated with the latch 80.
