Eventually, the three engaging claws 20u provided in the vicinity of the upper edge portion 13 of the lid body 10 and the two engaging claws 20d provided in the vicinity of the lower edge portion 14 of the lid body 10 Placed on the subject. Of course, the arrangement of the engaging claws 20 is not limited to the above-described mode. Since the engaging claws 20 are engaged with the inspection port 2, the number and position thereof are appropriately determined according to the shape and dimensions of the inspection port 2.

  The shape of the engaging claw 20 of this embodiment is as follows. That is, as shown in FIGS. 9 and 10, the three engaging claws 20 u provided on the upper surface of the first upper wall 41 u of the first recess 41 are all in the Y-axis positive direction from the first upper wall 41 u. The engaging surface 20u1 rises substantially vertically toward the upper surface, and the tapered portion 20u2 descends from the upper end of the engaging surface 20u1 to the first upper wall 41u on the Z-axis negative side. On the other hand, the two engaging claws 20d provided on the lower surface of the second lower wall 42d of the second recess 42 are both engaging surfaces 20d1 that rise substantially vertically from the second lower wall 42d in the negative Y-axis direction. And a tapered portion 20d2 rising from the engagement surface 20d1 to the second lower wall 42d on the Z-axis negative side. In other words, each of the engaging claws 20 (20u, 20d) is opposed to the engaging surfaces 20u1, 20d1 parallel to the XY plane and the first upper wall 41u or the second lower wall 42d as viewed from the X-axis direction. Tapered portions 20u2 and 20d2 that form acute angles and reach the tips of the engagement surfaces 20u1 and 20d1.

  Further, the two engagement claws 20d provided on the lower surface of the second lower wall 42d of the second recess 42 from the upper ends of the three engagement claws 20u provided on the upper surface of the first upper wall 41u of the first recess 41 are shown. The distance to the lower end (distance in the Y-axis direction) d1 (see FIG. 8) is slightly larger than the separation distance D (see FIG. 3) between the upper edge 3a and the lower edge 3b of the inspection port 2 to be attached. It has become. On the other hand, from the base portion of the three engaging claws 20u, that is, the upper surface of the first upper wall 41u of the first recess 41, the root portion of the two engaging claws 20d, that is, the second lower wall 42d of the second recess 42 is provided. The distance to the bottom surface (distance in the Y-axis direction) d2 (see FIG. 8) is slightly smaller than the separation distance D.

  The grip portion 30 provided on the front surface 11 of the lid body 10 has a predetermined length along the X-axis direction, and is provided integrally with the lid body 10 immediately below the second lower wall 42d of the second recess 42. It has been. Specifically, as shown in FIG. 10, the grip portion 30 has a U-shaped cross-sectional shape that protrudes from the front surface 11 of the lid body 10 toward the positive direction of the Z axis, and the upper wall portion 31 u. Is formed to be continuous with the second lower wall 42d of the second recess 42. As a result, the force applied to the grip portion 30 is directly transmitted to the second lower wall 42d of the second recess 42.

  Further, as shown in FIGS. 2, 5, 9, and 10, a seal portion 50 is provided on the back surface 12 of the lid body 10 in the vicinity of the peripheral edge portion thereof. When the lid 100 is attached to the inspection port 2, the seal unit 50 comes into close contact with the edge region 3 e of the inspection port 2 so that liquid (particularly, water or hot water) can flow through the inspection port 2. This is to prevent intrusion into the inside. The edge region 3e of the inspection port 2 is a region on the near side in FIG. 3 and means a region having a certain width including the edge 3 and a slight outer peripheral region of the edge 3. (See FIG. 3). For example, rubber is preferably used as the material of the seal portion 50, but the material is not limited to this, and any material that can be in liquid-tight contact with the edge region 3 e of the inspection port 2 may be used.

  As shown in FIG. 5, an attachment surface 15 for attaching the seal portion 50 is provided in the vicinity of the peripheral portion of the lid main body 10 without interruption over the entire periphery of the peripheral portion. The mounting surface 15 of the present embodiment is configured as a flat surface parallel to the XY plane. A band-shaped sealing material is attached to the mounting surface 15 with an adhesive. Of course, the seal portion 50 may be formed integrally with the lid body 10 by, for example, two-color molding.

  Furthermore, as shown in FIGS. 4 to 10, the lid body 10 has a second seal portion 16 at the peripheral edge. The second seal portion 16 is for making it difficult for liquid (particularly water or hot water) to reach the seal portion 50 by closely contacting the edge region 3e of the inspection port 2 on the outer periphery of the seal portion 50. is there. As shown in FIGS. 9 and 10, the second seal portion 16 formed on the lower edge portion 14 of the lid body 10 has components in the Y-axis negative direction and the Z-axis negative direction from the portion below the seal portion 50. It extends in a slanting direction (lower left direction in FIGS. 9 and 10). On the other hand, as shown in FIG. 9, the second seal portion 16 formed on the upper edge portion 13 of the lid body 10 has components in the Y-axis positive / negative direction and the Z-axis negative direction from the portion above the seal portion 50. It extends in a slanting direction (upper left in FIG. 9). The tip 16t of the second seal part 16 is located on the Z axis negative side with respect to the seal part 50. The second seal portion 16 is similarly provided on a pair of edge portions facing each other across the Y axis. That is, it extends from the outer periphery of the seal portion 50 in a direction having a component away from the origin and a component in the negative Z-axis direction, and its tip 16t is positioned on the negative Z-axis side with respect to the seal portion 50. doing. The second seal portion 16 is made of the same resin material as that of the lid main body 10, but has an appropriate elasticity because the thickness thereof is thin enough to bend and deform relatively easily. ing.

  Further, as shown in FIGS. 1, 2, 4, 5, and 7, the second seal portion 16 is provided with a notch 16n in a region overlapping the negative Y axis when viewed from the Z axis direction. ing. This notch 16n is for discharging the liquid that has entered the space formed between the inner surface (the surface on the back surface 12 side) of the second seal portion 16 and the edge region 3e of the inspection port 2 to the outside. is there. As shown in FIGS. 4 and 5, the notch 16n of the present embodiment has a semicircular shape.

  Next, the operation of the lid 100 according to this embodiment as described above will be described.

  The lid 100 is press-fitted into the inspection port 2 in such a state after the posture is adjusted so that the grip portion 30 is located below and the front surface 11 faces the near side (as shown in FIG. 4). During the press-fitting, the tapered portions 20u2 of the three engaging claws 20u provided on the upper surface of the first upper wall 41u of the first concave portion 41 and the lower surface of the second lower wall 42d of the second concave portion 42 are provided. The tapered portions 20d2 of the two engaging claws 20d interfere with the upper edge portion 3a and the lower edge portion 3b of the inspection port 2, respectively. At this time, the lid 100 is pressed against the inspection port 2 with a larger force, so that the upper edge portion 3a and the lower edge portion 3b of the inspection port 2 ride on the tapered portions 20u2 and 20d2 of the respective engaging claws 20u and 20d. Accordingly, the first upper wall 41u is bent downward and the second lower wall 42d is bent upward. Then, by further pressing the lid 100 against the inspection port 2, the upper edge portion 3a and the lower edge portion 3b of the inspection port 2 get over the tips of the engaging claws 20u and 20d. Accordingly, the engaging claws 20 u and 20 d are engaged with the edge portions 3 (3 a and 3 b) of the inspection port 2, and the lid 100 is attached to the inspection port 2. Since the mechanical strength of the lid body 10 is improved due to the presence of the structures 17 and 18, the lid body 10 is not greatly deformed or damaged during the attachment process.

  When such a lid 100 is attached, the seal portion 50 is pressed against the edge region 3e of the inspection port 2 and seals the inspection port 2 from the outside in a liquid-tight manner. Further, at this time, the region including the tip 16 t of the second seal portion 16 is pressed against the edge region 3 e of the inspection port 2 on the outer periphery of the seal portion 50. Thereby, the 2nd seal | sticker part 16 closely_contact | adheres to the edge area | region 3e of the inspection port 2, deform | transforming moderately. As a result, the inspection port 2 is double-sealed by the two seal portions 50 and 16. In addition, liquid (especially water or hot water) may enter into the space formed between the inner surface (the surface on the back surface 12 side) of the second seal portion 16 and the edge region 3e of the inspection port 2. However, the invading liquid is smoothly discharged to the outside through the notch 16 n provided in the second seal portion 16. This prevents the edge region 3e of the inspection port 2 from becoming unsanitary.

  On the other hand, when removing the lid 100 from the inspection port 2, the operator may pull the grip portion 30 toward the front side (the front side in FIG. 4). At this time, the force pulling the grip portion 30 is transmitted to the second lower wall 42d of the second recess 42, whereby the second lower wall 42d is bent upward and deformed. Along with this bending deformation, the two engaging claws 20d provided on the lower surface of the second lower wall 42d are displaced upward. As a result, the lower ends of the two engaging claws 20d get over the lower edge 3b of the inspection port 2 in the pulling direction (front side in FIG. 3), and the two engaging claws 20d and the lower edge 3b of the inspection port 2 The engagement is released. Thereafter, the lid 100 is pulled down by the operator, and the three engaging claws 20u provided on the upper surface of the first upper wall 41u of the first recess 41 and the upper edge 3a of the inspection port 2 are easily provided. The engagement is released.

  Then, after the predetermined inspection through the inspection port is completed, the lid 100 may be attached to the inspection port 2 in accordance with the mounting procedure described above. As a result, the inspection port 2 is closed again by the lid 100.

  According to the lid 100 as described above, since the lid main body 10 and the engaging claw 20 are integrally provided, it is possible to provide a lid that has fewer parts than the conventional one and is easy to attach and detach. it can.

  Since the lid body 10 is provided with a plurality of engaging claws 20 (20u, 20d), the lid 100 can be firmly attached to the inspection port 2.

  The lid main body 10 is provided with two engaging claws 20d in the vicinity of the lower edge portion 14, and a grip portion 30 is provided below the two engaging claws 20d. Thereby, since the force applied to the holding part 30 is effectively transmitted to the two engaging claws 20d, the work for removing the lid 100 from the inspection port 2 is easy.

  Further, the three engaging claws 20 u are arranged in the vicinity of the upper edge portion 13 of the lid body 10, that is, at a position corresponding to the upper edge portion 3 a of the inspection port 2. For this reason, the lid 100 can be firmly attached to the inspection port.

  The front surface 11 of the lid body 10 is formed with a recess 42 extending above the two engaging claws 20d along the arrangement direction (X-axis direction) of the engaging claws 20d. For this reason, since the force applied to the grip part 30 effectively displaces each engaging claw 20d due to the bending of the concave part 42, the work for removing the lid 100 from the inspection port 2 is further facilitated. It is.

  Further, a seal portion 50 is provided on the back surface 12 of the lid body 10 at a position corresponding to the edge portion 3 of the inspection port 2. For this reason, the penetration | invasion of the liquid to the inside of the inspection port 2 can be prevented.

  In the above description, the example in which the engaging claw 20 is integrally provided on the back surface 12 of the lid main body 10 has been described. However, the present invention is not limited to such an embodiment. For example, in another embodiment, a plurality of appropriate engaging members are formed separately from the lid main body instead of the engaging claws 20, and the lid is configured by assembling these engaging members to the lid main body. May be. In this case, each engaging member is configured so that it is not necessary to be individually engaged with the edge of the inspection port 2 when the lid body is attached to the inspection port 2.
