Description

The present invention relates to an outdoor installation device that is installed and used outdoors.

Conventionally, outdoor installation devices are used for purposes such as checking the functionality of speakers installed outdoors and for processing various types of information collection. In such outdoor installation devices, the electrical and electronic components that are the subject of maintenance are often housed in a device housing with an openable lid.

A known device housing of this type has a body-side mounting base provided near the upper and lower ends of the opening side of the housing body, a similar lid-side mounting base provided on the lid, and a hinge shaft provided on the side that joins with the housing body, with a locking portion formed at its tip (see, for example, Patent Document 1). A hinge bearing portion is provided on the housing body at a position that corresponds to the hinge shaft portion when the lid is closed. Then, with the lid open at 180°, the hinge shaft portion is attached to the hinge bearing portion. When the angle becomes smaller than 180° when the lid is closed, the locking portion locks onto the side of the hinge bearing portion, preventing the lid from coming off.

JP 2001-119161 A

However, in conventional communication device housings, when the lid is opened 180 degrees relative to the housing body, the hinge shaft can be removed from the hinge bearing, which can cause the lid to come off the housing body. This means that a separate stopper, such as a bolt, is required to prevent the lid from opening 180 degrees relative to the housing body during maintenance, which allows it to be removed. This increases the number of parts and the number of assembly steps.

In addition, in communication device housings that are generally installed outdoors, a vent section for internal ventilation of the housing body needs to be provided. However, if a hinge section that connects the housing body and the lid section so that they can be opened and closed is provided on the vent side of the housing body, there is a risk that the lid section will come into contact with the vent section when the lid section is opened, blocking or damaging the vent section, which may result in a loss of humidity control effect.

Therefore, the present invention focuses on the above-mentioned problems and aims to provide an outdoor installation device that can prevent the lid from coming off the housing body during maintenance without increasing the number of parts or assembly labor.

In order to solve the above-mentioned problems, the outdoor installation device of the present invention is an outdoor installation device including an equipment housing for accommodating equipment components to be installed outdoors, the equipment housing including: a housing main body portion formed in a bottomed box shape and accommodating the equipment components inside; a lid portion attached to the housing main body portion so as to be openable and closable so as to cover an opening of the housing main body portion; and a hinge portion connecting the housing main body portion and the lid portion, the hinge portion including a hinge shaft portion provided integrally with either the housing main body portion or the lid portion, and a hinge bearing portion provided integrally with either the lid portion or the housing main body portion, At least one of the hinge bearing portions has an integral stopper portion which limits the opening degree of the lid portion relative to the housing main body portion, the hinge bearing portion has a protrusion portion which protrudes outward from at least the side wall of the housing main body portion or the outer peripheral surface of the lid portion, and a bearing hole which is provided in the protrusion portion and through which the hinge shaft portion is inserted, the hinge shaft portion has a base portion which protrudes outward from at least the outer peripheral surface of the lid portion or the side wall of the housing main body portion, and an axis which extends from the base along the outer peripheral surface or the side wall and is inserted into the bearing hole, and the stopper portion is integrally molded into the protrusion .

According to the outdoor installation device of the present invention, the stopper portion that limits the opening degree of the lid portion relative to the housing body portion is provided integrally with at least one of the housing body portion or the lid portion, so that the lid portion can be prevented from coming off the housing body portion during maintenance without increasing the number of parts or assembly labor. In other words, because the lid portion is connected to the housing body portion via the hinge portion, it is possible to prevent the lid portion that is opened during maintenance from falling off. In addition, because the stopper portion also functions as a reinforcing portion for the hinge portion, damage to the hinge portion can be prevented.

Here, in the outdoor installation device of the present invention, a vent portion for internal ventilation may be provided on the side wall on which the hinge portion of the housing main body is provided, protruding outward from the outer circumferential surface of the side wall .

This configuration makes it possible to prevent the vent from being blocked or damaged by the lid that is open relative to the housing body. This stabilizes the internal ventilation of the device housing and provides sufficient humidity control. In addition, the stopper acts as a visor, preventing foreign matter such as dirt from adhering to the vent and preventing clogging of the vent. In addition, because the stopper is integrally molded with the protruding portion, a stopper that can prevent damage to the vent can be provided without increasing the number of parts or assembly steps.

In the outdoor installation device of the present invention, it is preferable that the hinge section allows the hinge shaft section and the hinge bearing section to be attached and detached when the lid section is opened at a preset angle relative to the housing body section, and that a restricting section is formed that engages the hinge shaft section and the hinge bearing section to prohibit attachment and detachment of the hinge shaft section and the hinge bearing section when the lid section is opened at an angle other than the preset angle relative to the housing body section.

With this configuration, the lid can be adjusted to be attached or detached from the housing body, so a restricting section can be provided that can prevent the lid from coming off the housing body without increasing the number of parts or assembly steps. In addition, because the lid is connected to the housing body via a hinge section, it is possible to prevent the lid from falling off when opened during maintenance.

In order to solve the above-mentioned problems, the outdoor installation device of the present invention is an outdoor installation device including an equipment housing for accommodating equipment components to be installed outdoors, the equipment housing including a housing main body formed in a bottomed box shape and accommodating the equipment components inside, a lid attached to the housing main body in an openable and closable manner so as to cover an opening of the housing main body, and a hinge portion connecting the housing main body and the lid, the hinge portion including a hinge shaft portion integrally provided with either the housing main body or the lid, and a hinge bearing portion integrally provided with either the lid or the housing main body, and at least one of the housing main body or the lid is provided with a hinge shaft portion integrally provided with either the housing main body or the lid. At least one of the hinge portions has an integral stopper portion for limiting the opening degree of the lid portion relative to the housing main body portion, the hinge bearing portion has a bearing hole through which the hinge shaft portion is inserted and is integrally formed on at least the outer peripheral surface of the lid portion or the side wall of the housing main body portion, the hinge shaft portion has a base portion integrally formed on at least the side wall of the housing main body portion or the outer peripheral surface of the lid portion, and an axis extending from the base along the side wall or the outer peripheral surface and inserted into the bearing hole, and the center line of the hinge bearing portion and the hinge shaft portion is formed so as not to protrude outward from the side wall of the housing main body.
According to the outdoor installation device of the present invention, the stopper portion that limits the opening degree of the lid portion relative to the housing body portion is provided integrally with at least one of the housing body portion or the lid portion, so that the lid portion can be prevented from coming off the housing body portion during maintenance without increasing the number of parts or the number of assembly steps. In other words, since the lid portion is connected to the housing body portion via the hinge portion, it is possible to prevent the lid portion that is opened during maintenance from falling off. In addition, since the stopper portion also functions as a reinforcing portion for the hinge portion, it is possible to prevent damage to the hinge portion.

Furthermore, in the outdoor installation device of the present invention, it is preferable that a recess recessed inward from an outer circumferential surface of the side wall on the side where the hinge part is provided is provided in the side wall, and a vent part for internal ventilation is provided in the recess. It is also preferable that the hinge part allows the hinge shaft part and the hinge bearing part to be attached and detached when the lid part is opened at a preset angle relative to the housing body part, and that the hinge shaft part and the hinge bearing part are engaged with each other to prohibit the hinge shaft part and the hinge bearing part from being attached and detached when the lid part is opened at an angle other than the preset angle relative to the housing body part.
According to this configuration, when the vent is provided in a recess formed in the side wall of the housing main body on the side where the hinge is provided, the hinge bearing and the hinge shaft are provided integrally with the outer peripheral surface of the lid or the side wall of the housing main body without protruding outward from the outer peripheral surface of the lid or the side wall of the housing main body, respectively, so that in addition to the above-mentioned effect, the interference portion between the lid and the housing main body in an open state relative to the housing main body can function as a stopper that limits the opening degree of the lid relative to the housing main body. And the lid itself that opens relative to the housing main body functions as a stopper, and the lid can be prevented from blocking or damaging the vent, stabilizing the internal ventilation of the device housing and obtaining a sufficient humidity control effect.

The outdoor installation device of the present invention can prevent the lid from coming off the housing body without increasing the number of parts or assembly steps, and can prevent the lid from falling off when opened during maintenance. In addition, the stopper also functions as a reinforcing part for the hinge, preventing damage to the hinge.

Below, one embodiment of the outdoor installation device according to the present invention will be described in detail with reference to Figures 1 to 6.

Figure 1 is a perspective view of the outdoor installation device 1 according to the embodiment, as viewed from the front side with the lid 3 open. Figure 2 is an exploded perspective view of the outdoor installation device 1 according to the embodiment, as viewed from the rear side with the lid 3 open.

Figure 4 is a perspective view of an enlarged hinge portion 4, which is a main part of the outdoor installation device 1 according to the embodiment. Figure 5 is a view of the outdoor installation device 1 according to the embodiment, as viewed from the top side with the lid 3 fully open. Figure 6 is a perspective view of the outdoor installation device 1 according to the embodiment, as viewed from the rear side with the lid 3 fully open.

The outdoor installation device described below is, for example, a sound pressure measuring device that measures the sound pressure emitted by a speaker to check the functionality of the speaker as an alarm at facilities such as railroad crossings installed at various locations along railway lines and transmits the measurement results wirelessly, but the device can also be widely applied to various other devices installed outdoors. Also, since the present invention relates to the structure of the device housing of an outdoor installation device, the following description of the device parts housed therein will be omitted for the sake of convenience.

As shown in Figures 1 to 3, the outdoor installation device 1 includes a device housing 10 having a housing body 2 formed in a box shape with a bottom and housing device components (not shown) therein, a lid 3 attached to the housing body 2 in an openable and closable manner so as to cover the opening of the housing body 2, and a hinge 4 connecting the housing body 2 and the lid 3.

The housing body 2 is made of hard resin and has a flat, bottomed rectangular cylinder shape, and is designed to house device components (not shown) inside. The lid 3 is made of hard resin and has a rectangular plate shape, just like the housing body 2, and is fixed to the housing body 2 so as to close the opening of the housing body 2. The housing body 2 and the lid 3 are connected via a hinge 4 so as to be able to open and close, and are sealed by the seal 11.

The sealing portion 11 is a flexible ring-shaped resin such as rubber that is sandwiched between the rectangular opening edge 21 of the housing body 2 and the lid portion 3 to seal the gap between the housing body 2 and the lid portion 3.

The four female screws 22 are threaded portions that are distributed along the opening edge 21 of the housing body 2 in the circumferential direction of the opening edge 21, specifically, adjacent to the four corners of the rectangular opening edge 21. The four male screws 31 are threaded members that penetrate the four corners of the rectangular plate-shaped cover 3 and are screwed one-to-one into the four female screws 22 of the housing body 2, and fasten the cover 3 to the housing body 2. Four internal tooth washers (not shown) may be fitted into the middle of each male screw 31 so as to be located between the cover 3 and the housing body 2 when the cover 3 is fastened to the housing body 2.

In this embodiment, the hinge section 4 is arranged at two positions, one above the other, in the vertical direction when the device housing 10 is installed. The hinge section 4 is a portion that connects the cover section 3 to the housing body section 2 so that the cover section 3 can be opened and closed. In this embodiment, the hinge section 4 is arranged to connect the outer peripheral surface 32a, which corresponds to the long side of the rectangle that extends linearly in the cover section 3 and the housing body section 2, each of which has a rectangular periphery, and the side wall 23a. In this case, the two hinge sections 4 are provided at a distance from each other in the extension direction D1 of the outer peripheral surface 32a and the side wall 23a. The arrangement of the hinge sections 4 is not limited to two positions, and multiple hinge sections 4 may be arranged. In this case, it is desirable that the hinge sections 4 are arranged vertically sandwiching the vent section 5 described later.

The hinge section 4 has a hinge shaft section 41 that is provided integrally with either the housing body section 2 or the lid section 3 (in this embodiment, the lid section 3), and a hinge bearing section 42 that is provided integrally with the other of the lid section 3 or the housing body section 2 (in this embodiment, the housing body section 2). In addition, the hinge section 4 has a stopper section 43 that is provided integrally with at least one of the housing body section 2 or the lid section 3, and that limits the opening degree of the lid section 3 relative to the housing body section 2. Furthermore, a vent section 5 for internal ventilation is provided on the side wall 23a on the side where the hinge section 4 of the housing body section 2 is provided, protruding outward from the outer circumferential surface of the side wall 23a.

The hinge shaft portion 41 has a base portion 41a that protrudes outward from at least the outer peripheral surface 32a of the lid portion 3 or the side wall 23a of the housing body portion 2 (in this embodiment, the outer peripheral surface 32a of the lid portion 3), and a shaft 41b that is on the central axis of the base portion 41a and extends from the base portion 41a along the extension direction D1 of the outer peripheral surface 32a (or the side wall 23a) and is inserted into the hinge bearing portion 42 (more specifically, the bearing hole 42c described later). Note that in this embodiment, the case where the shaft 41b is located on the central axis of the base portion 41a will be described, but although it is essential that the shaft 41b and the bearing hole 42c are located coaxially, the base portion 41a and the shaft 41b may be offset and do not necessarily have to be located coaxially.

The hinge bearing portion 42 has a protrusion 42a that protrudes outward from at least the side wall 23a of the housing body 2 or the outer peripheral surface 32a of the cover 3 (in this embodiment, the side wall 23a of the housing body 2), and a bearing 42b that is provided on the protrusion 42a and through which the hinge shaft portion 41 is inserted. Specifically, the protrusion 42a is made of a pair of L-shaped plate-like members that protrude outward from the outer peripheral surface of the side wall 23a of the housing body 2, and a bearing 42b is provided to connect these plate-like members. The bearing 42b has a bearing hole 42c through which the shaft 41b of the hinge shaft portion 41 is inserted, formed along the extension direction D1 of the side wall 23a. Note that the protrusion 42a is not limited to being composed of a pair of plate-like members, and for example, the pair of plate-like members may be integrally molded into a block shape.

4, the hinge portion 4 is provided with a restricting portion 6 that allows the hinge shaft portion 41 and the hinge bearing portion 42 to be attached and detached when the cover portion 3 is opened at a preset angle relative to the housing body portion 2, and that engages the hinge shaft portion 41 and the hinge bearing portion 42 to prohibit the hinge shaft portion 41 and the hinge bearing portion 42 from being attached and detached when the cover portion 3 is opened at an angle other than the preset angle relative to the housing body portion 2. Specifically, the restricting portion 6 is composed of a flange-shaped protrusion portion 41c provided at the tip of the shaft 41b of the hinge shaft portion 41 and a bearing hole 42c of the hinge bearing portion 42. The protrusion portion 41c has a shape composed of, for example, opposing straight sides 41ca and opposing curved sides 41cb. The bearing hole 42c is also configured in a shape corresponding to the shape of the protrusion portion 41c. The angle at which the protrusions 41c and the bearing holes 42c are aligned and the protrusions 41c are inserted through the bearing holes 42c is preset as an angle that allows the hinge shaft 41 and the hinge bearing 42 to be attached and detached. The "preset angle" is any angle between the housing body 2 and the lid 3 other than the angle at which the lid 3 is fully open and fully closed relative to the housing body 2. For example, the lid 3 may be at an angle of 90°, which is an intermediate position between the fully open and fully closed positions, relative to the housing body 2. In this way, by setting the angle to an angle other than the fully open and fully closed positions, the lid 3 will not come off the housing body 2 unless the operator intentionally adjusts the angle during the opening and closing of the lid 3.

In addition, a stopper portion 43 is integrally molded with the protrusion 42a of the hinge bearing portion 42. Specifically, as shown in Figs. 5 and 6, the stopper portion 43 is composed of the protrusion 42a and the side wall 32b of the lid portion 3 on the side where the hinge portion 4 is provided. When the lid portion 3 is fully open relative to the housing body portion 2, the side wall 32b of the lid portion 3 abuts against the protrusion 42a, thereby restricting the opening degree of the lid portion 3 relative to the housing body portion 2. In other words, the side wall 32b of the lid portion 3 abuts against the protrusion 42a of the hinge bearing portion 42, thereby functioning as the stopper portion 43.

At this time, as described above, the side wall 23a on the side where the hinge portion 4 of the housing main body 2 is provided has the vent portion 5 for internal ventilation protruding outward from the outer circumferential surface of the side wall 23a. The hinge portion 4 is provided on the side wall 23a of the housing main body 2 so as to sandwich the vent portion 5 in the extension direction D1. Therefore, by setting the protruding amount of the vent portion 5 within the protruding amount of the protruding portion 42a of the hinge bearing portion 42 in the hinge portion 4 (in other words, setting the protruding amount of the protruding portion 42a to be greater than the protruding amount of the vent portion 5), when the lid portion 3 is fully opened relative to the housing main body 2, the side wall 32b of the lid portion 3 abuts against the protruding portion 42a to regulate the opening degree of the lid portion 3 relative to the housing main body 2, so that the vent portion 5 can be prevented from being blocked or damaged by the lid portion 3 opened relative to the housing main body 2. Therefore, the internal ventilation of the device housing 10 is stabilized, and a sufficient humidity control effect can be obtained. In addition, the stopper portion 43 functions as a visor, preventing damage to the vent portion 5 due to freezing of water caused by rainwater or snow accumulation, expansion, so-called ice punctures, and adhesion of foreign matter such as dirt, thereby preventing clogging of the vent portion. In addition, since the stopper portion 43 is integrally molded with the protruding portion 42a, it is possible to provide a stopper portion 43 that can prevent damage to the vent portion 5 without increasing the number of parts or assembly steps.

As described above, according to the outdoor installation device 1 of this embodiment, the stopper portion 43 that limits the opening degree of the lid portion 3 relative to the housing main body portion 2 is provided integrally with at least one of the housing main body portion 2 or the lid portion 3, so that the lid portion 3 can be prevented from coming off the housing main body portion 2 during maintenance without increasing the number of parts or assembly labor. In other words, because the lid portion 3 is connected to the housing main body portion 2 via the hinge portion 4, it is possible to prevent the lid portion 3 from falling off when opened during maintenance. In addition, because the stopper portion 43 also functions as a reinforcing portion for the hinge portion 4, damage to the hinge portion 4 can be prevented.

Here, in the outdoor installation device 1 of this embodiment, a vent section 5 for internal ventilation may be provided on the side wall 23a on the side where the hinge section 4 of the housing main body section 2 is provided, protruding outward from the outer peripheral surface of the side wall 23a. The hinge bearing 42 has a protrusion 42a that protrudes outward from at least the side wall 23a of the housing body 2 or the outer circumferential surface 32a of the lid 3, and a bearing hole 42c that is provided on the protrusion 42a and through which the hinge shaft 41 is inserted. The hinge shaft 41 has a base 41a that protrudes outward from at least the outer circumferential surface 32a of the lid 3 or the side wall 23a of the housing body 2, and a shaft 41b that is on the central axis of the base 41a, extends from the base 41a along the outer circumferential surface 32a or the side wall 23a, and is inserted into the bearing hole 42c. It is preferable that the protrusion 42a is integrally molded with a stopper 43.

This configuration can prevent the lid 3 from opening on the housing body 2 from blocking or damaging the vent 5. This stabilizes the internal ventilation of the device housing 10 and provides a sufficient humidity control effect. In addition, the stopper 43 functions as a eaves, preventing damage to the vent 5 due to freezing of water caused by rainwater or snow accumulation, and preventing the adhesion of foreign matter such as dirt to the vent 5, and thus preventing clogging of the vent 5. In addition, since the stopper 43 is integrally molded with the protrusion 42a, the stopper 43 can be provided to prevent damage to the vent 5 without increasing the number of parts or assembly steps. In order for the stopper 43 to function as an eaves for the vent 5, it is desirable that the hinge bearing 42 is disposed on the housing body 2 side and the hinge shaft 41 is disposed on the lid 3 side, as shown in FIG. 5.

In addition, in the outdoor installation device 1 of this embodiment, the hinge section 4 allows the hinge shaft section 41 and the hinge bearing section 42 to be attached and detached when the lid section 3 is opened relative to the housing body section 2 at the aforementioned preset angle, and preferably has a restricting section 6 formed to engage the hinge shaft section 41 and the hinge bearing section 42 and prohibit the hinge shaft section 41 and the hinge bearing section 42 from being attached and detached when the lid section 3 is opened relative to the housing body section 2 at an angle other than the preset angle.

With this configuration, the attachment and detachment of the lid 3 to the housing body 2 can be adjusted, so that a restricting portion 6 can be provided that can prevent the lid 3 from coming off the housing body 2 without increasing the number of parts or assembly steps. In addition, because the lid 3 is connected to the housing body 2 via the hinge portion 4, it is possible to prevent the lid 3 from falling off when opened during maintenance.

The most preferable arrangement of the hinge shaft 41 and hinge bearing 42 of the hinge section 4 is that the hinge bearing 42 is arranged on the housing body 2 side and the hinge shaft 41 is arranged on the lid 3 side. The most preferable arrangement of the hinge shaft 41 is that the shaft 41b faces downward and is inserted from above into the bearing hole 42c of the hinge bearing 42. This arrangement prevents rainwater from accumulating in the bearing hole 42c, thereby avoiding damage caused by freezing expansion. In addition, the life of the regulating section 6 can be improved because the weight of the housing body 2 and the lid 3 is not constantly applied to the protrusion 41c of the regulating section 6.

In addition, the following arrangement of the hinge shaft 41 and the hinge bearing 42 of the hinge part 4 is not preferable and should be avoided. Specifically, it is not preferable to arrange the hinge shaft 41 on the housing main body 2 side so that the shaft 41b faces upward, and to insert the shaft 41b from below into the bearing hole 42c of the hinge bearing part 42 arranged on the lid part 3 side. In this case, the upper surface side of the bearing hole 42c is exposed, so rainwater may accumulate and may be damaged due to freezing and expansion. In addition, it is not preferable to arrange the shaft 41b of the hinge shaft 41 on the housing main body 2 side so that the shaft 41b faces downward, and to insert the shaft 41b from above into the bearing hole 42c of the hinge bearing part 42 arranged on the lid part 3 side. In this case, the weight of the housing main body 2 and the lid part 3 is constantly applied to the protrusion 41c of the regulating part 6 provided on the shaft 41b, which may lead to damage to the regulating part 6.

Although the embodiments of the present invention have been described in detail above with reference to the drawings, the specific configuration is not limited to these embodiments, and the present invention also includes design changes that do not deviate from the gist of the present invention.

In the above embodiment, the vent portion 5 is provided to protrude outward from the side wall 23a on the side where the hinge portion 4 of the housing main body portion 2 is provided, but the present invention is not limited to this. Specifically, for example, as shown in FIG. 7 or FIG. 8, the side wall 23a on which the hinge portion 4 of the housing main body portion 2 is provided may be provided with a recess 24 recessed inward from the outer circumferential surface of the side wall 23a, and the vent portion 5 for internal ventilation may be provided within the recess 24.

In addition, although the hinge bearing portion 42 has been described as being arranged to protrude outward from the outer peripheral surface of the side wall 23a of the housing main body portion 2, it may also be arranged in a state where it does not protrude outward from the outer peripheral surface of the side wall 23a. That is, as shown in Figure 7 or Figure 8, the hinge bearing portion 42 has a protrusion 42a integrally formed with at least the side wall 23a of the housing main body 2 (or the outer peripheral surface 32a of the lid portion 3), and a bearing hole 42c formed in the protrusion 42a and through which the hinge shaft portion 41 is inserted, and the hinge shaft portion 41 has a base 41a integrally formed with at least the outer peripheral surface 32a of the lid portion 3 or the side wall 23a of the housing main body 2, and an axis 41b extending along the outer peripheral surface 32a (or side wall 23a) on the central axis of the base 41a and inserted into the bearing hole 42c, and the center line of the hinge bearing portion 42 and the hinge shaft portion 41 may be formed so as not to protrude outward from the side wall 23a of the housing main body 2. In this embodiment, the case where the shaft 41b is located on the central axis of the base 41a will be described. Although the shaft 41b and the bearing hole 42c must be located on the same axis, the base 41a and the shaft 41b may be offset, and are not necessarily located on the same axis. In this case, as in the above-mentioned embodiment, the hinge part 4 allows the hinge shaft part 41 and the hinge bearing part 42 to be attached and detached when the cover part 3 is opened at a preset angle relative to the housing body part 2, and when the cover part 3 is opened at an angle other than the preset angle relative to the housing body part 2, the hinge shaft part 41 and the hinge bearing part 42 are engaged, and the hinge shaft part 41 and the hinge bearing part 42 are prohibited from being attached and detached.

According to this configuration, when the vent portion 5 is provided in the recess 24 formed in the side wall 23a of the housing body 2 on the side where the hinge portion 4 is provided, the hinge bearing portion 42 and the hinge shaft portion 41 are provided integrally with the outer peripheral surface 32a of the lid portion 3 or the side wall 23a of the housing body 2, respectively, without protruding outward from the outer peripheral surface 32a of the lid portion 3 or the side wall 23a of the housing body 2. Therefore, in addition to the effects of the above-mentioned embodiment, the interference portion between the lid portion 3 and the housing body 2 in an open state relative to the housing body 2 (i.e., the abutment portion between the side wall 32b of the lid portion 3 and the side wall 23a of the housing body 2 in FIG. 7, and the abutment portion between the L-shaped bent outer peripheral surface 32a of the lid portion 3 and the upper part of the side wall 23a of the housing body 2 in FIG. 8) can function as a stopper portion that limits the opening degree of the lid portion 3 relative to the housing body 2. The lid 3 itself, which is open relative to the housing body 2, functions as a stopper, preventing the lid 3 from blocking or damaging the vent 5, stabilizing the internal ventilation of the device housing 10 and providing sufficient humidity control.
