- Examples of the one-part curable resin include polyamide-based resin and styrene-based resin, but the surface of the ABS resin used for the outer case 26 is influenced by the adhesiveness to the polycarbonate resin and the molding temperature. From the viewpoint of melt viscosity, it is preferable to use a polyamide-based resin based on dimer acid, which is a natural fatty acid.
- the Shore hardness of the polyamide-based resin is 85 or less, and preferably in the range of 83 to 70. In polyamide-based resins with a Shore hardness higher than 85, repeated rapid temperature changes may cause the outer case and the one-part curable resin to peel off and the gap force may be submerged.
- the step portion 40b is configured such that the inner portion in the thickness direction at the tip of the side wall constituting the open end is one step higher than the outer portion. Accordingly, the one-part curable resin 50 is also arranged outside the inner part, that is, above the lower part of the outer part, and the inner part that is one step higher is sandwiched between the one-part curable resin 50. As a result, the contact area between the exterior case 40 and the one-component curable resin 50 at the open end of the exterior case 40 increases. For this reason, this partial force also suppresses the intrusion of water into the liquid crystal display unit 10, and further, the hardened one-component curable resin 50 is not easily peeled off from the outer case 40.

- the one-component curable resin 50 filled in the opening of the outer case 40 is in close contact with the inner surface of the side wall of the outer case 40 on the opening end side of the outer case 40. Prevents moisture from entering.
- the notch 56 is also formed on the side wall of the liquid crystal holder 48 corresponding to the notch 54 of the outer case 40, so the notch 54 is formed at the opening end of the outer case 40.
- the thickness of the part where the side wall of the outer case 40 and the one-part curable resin 50 are in close contact with each other (the vertical length in Figs. 4, 5, and 7) is the same as the other parts. It has become. As a result, the waterproof property in the vicinity of the notch 54 of the outer case 40 becomes more reliable.
- the position where the cutout portion 54 of the outer case 40 is formed is not particularly limited, but when the lead wire 52 is connected to one end of the circuit board 36 to be mounted in the outer case 40.
- the lead wire 52 formed on the side corresponding to the other end of the circuit board 36 and connected to the circuit board 36 is led out from the liquid crystal display unit 10 in a straight line.
- the size (depth) of the notch 56 of the liquid crystal holder 48 is determined by the thickness of the contact portion between the portion where the lead wire 52 is disposed and the outer case 40 and the one-part curable resin 50 in the surrounding portion ( It is preferable that the vertical lengths in FIGS. 4, 5 and 7 are set to be equal. This is because if it is shorter than the surrounding area, the peel resistance against sudden temperature changes will not be sufficient, and conversely, if the liquid crystal holder 48 is notched deeply so that the adhesion distance is longer than the surrounding area, the strength of the liquid crystal holder 48 will be reduced. This is because the pressure of the one-part curable resin 50 is lowered and cannot withstand the pressure when filling, and may be damaged.
- the thickness of the contact portion of the outer case 40 and the one-part curable resin 50 in the portion where the lead wire 52 is disposed and the surrounding portion is V and the deviation is 2 mm or more! /.

- a configuration derived from part 10 may be used.
- Concavities and convexities are formed on the wall surface of the outer case 40 that contacts (adheres) the one-component curable resin 50. ing. The uneven surface area increases the contact surface area between the outer case 40 and the one-component curable resin 50.
- the shape of the unevenness is not particularly limited, but there are a plurality of parallel grooves 60 (FIG. 10) extending in the circumferential direction of the opening of the outer case 40, or ⁇ 62 (FIG. 11), or irregular unevenness 64 (Fig. 12).
- the method of forming the irregularities 60, 62, 64 on the wall surface of the outer case 50 is not particularly limited, but, for example, a groove to be formed in a corresponding portion of a mold for molding the outer case 50
- the wall surface on which the unevenness of the exterior case is formed may be all the surfaces in contact with the one-component curable resin, particularly a part requiring an adhesive force, and the height difference of the unevenness may be changed depending on the location. .
- the unevenness of the wall surface of the outer case is preferably in the range of a height difference of ⁇ 100 m. If the height difference between the concave and convex is less than 1 ⁇ m, the outer case and the one-part curable resin are peeled off due to repeated rapid temperature changes that do not have enough surface area in contact with the one-part curable resin. It is preferable because it may be submerged.
- the height difference of the unevenness is larger than 1 m, there is a possibility that air may be trapped when injecting the one-part curable resin, and sufficient waterproofness may not be obtained. Further, when molding the outer case with a resin, it is not preferable because the mold force is also removed when the molded product is removed after molding, and it is therefore necessary to increase the die removal taper angle.
- the height of the unevenness is defined by the average value of the depth of the recess when the surface of the exterior case is concave, and is defined by the average value of the height of the protrusion when conversely, The In addition, when the dies are blasted or etched to form irregularities in the outer case, it is defined by the 10-point average height Rz.

- various environments in actual use For example, in severe winters, 60 ° C hot water may be passed through the water purifier body at 10 ° C.
- a hot melt adhesive [Macromelt (registered trademark) OM652] manufactured by Henkel, which has a softening point of 155 ° C and a Shore A hardness of 80, was used as a one-part curable resin.
- the adhesion distance in the thickness direction between the liquid-cured resin 50 and the outer case 40 of the finished liquid crystal is 3 mm at the location where the lead wires are arranged as shown in Fig. 7, and at the other outer periphery as well. It was 3 mm. In the waterproof test after the heat cycle, all three samples showed water intrusion into the circuit board. Good results were obtained.
