Description

The present invention relates to a fishing reel counter case.

A fishing reel counter case houses a display device for displaying water depth, etc., and a circuit board for controlling the display device and the motor. In Patent Document 1 listed below, a transparent resin lens is attached to a display window, and a display device is visually recognized through the lens. Forces may act on the lens from the outside. Furthermore, when the pressure inside the counter case increases due to heat dissipation from the circuit board, force acts on the lens from within. Therefore, it is necessary to firmly fix the lens to the display window.

On the other hand, in Patent Document 2 listed below, a transparent window portion is integrally molded with a case body portion by multicolor molding. In this case, it is necessary to ensure sufficient bonding strength between the transparent window and the case body and to prevent distortion of the transparent window.

<Third resin part 23>
The third resin part 23 is integrated with the first resin part 21. The third resin portion 23 includes a plurality of second button portions 8b and a connecting portion 80 that connects the second button portions 8b.

As described above, in the counter case in this embodiment, the first resin part 21 is provided with the second opening 42 , the third opening 43 , and the fourth opening 44 in proximity to the first opening 41 . It is being Therefore, when molding the second resin part 22 following the first resin part 21, the gas in the mold is smoothly exhausted from the second opening 42, the third opening 43, and the fourth opening 44. . Therefore, distortion is less likely to occur in the transparent panel portion 32a. In particular, since the second opening 42, the third opening 43, and the fourth opening 44 are distributed and arranged around the first opening 41, the gas is effectively discharged. Furthermore, since the four fourth openings 44 are provided close to the four panel corners 320 of the transparent panel section 32a, distortions that tend to occur at the panel corners 320 are effectively suppressed.

Then, the first opening 41 is filled with the transparent panel section 32a, and the second opening 42, the third opening 43, and the fourth opening 44 are filled with the first filling section 70, the second filling section 72, and the third filling section, respectively. Since the portion 74 is filled in, high adhesion between the first resin portion 21 and the second resin portion 22 is obtained, and the strength is increased. Therefore, the transparent panel portion 32a is difficult to come off from the first resin portion 21.

Moreover, the first bridge section 46, the second bridge section 50, and the third bridge section 54 support the second resin section 22 from above. Furthermore, the first bridge section 46 is interposed between the transparent panel section 32a and the first filling section 70, the second bridge section 50 is interposed between the transparent panel section 32a and the second filling section 72, and the third bridge section 46 is interposed between the transparent panel section 32a and the first filling section 70. The bridge portion 54 is interposed between the transparent panel portion 32a and the third filling portion 74. For example, when the inside of the counter case becomes high temperature due to heat dissipation from transistors, etc., a large internal pressure acts on the second resin part 22, especially the transparent panel part 32a, and an upward force acts on the transparent panel part 32a. do. Even in such a case, by supporting the second resin part 22 from above by the first bridge part 46, second bridge part 50, and third bridge part 54, it is possible to sufficiently withstand the internal pressure. can. In addition, since the first recess 47 and the second recess 51 are provided, the first bridge 46 and the second bridge 50 are pressed by the mold, and the first bridge 46 and the second bridge 50 are not distorted. Hard to occur.

Further, the first engaging portion 71 engages with the first step portion 49, and the first engaging portion 71 is supported by the first step portion 49 from below. Further, the second engaging portion 73 engages with the second step portion 53, and the second engaging portion 73 is supported from below by the second step portion 53. Therefore, even if a downward external force is applied to the second resin part 22, particularly the transparent panel part 32a, the second resin part 22 is unlikely to come off downward from the first resin part 21.
