The seal part 54 has flexibility. The seal portion 54 is made of, for example, a thermoplastic elastomer. The seal portion 54 also serves as a switch spring.

  The switch portion 55 extends upward from the seal portion 54 and protrudes outward from the second through hole 515. That is, the switch part 55 protrudes upward from the top plate 511 of the case main body part 51. The switch part 55 is cylindrical. By pressing the switch unit 55, the display of the display unit 101 is switched. Note that the switch portion 55 can be formed of the same material as the case main body portion 51. For example, the switch unit 55 is made of ABS resin.

  The counter 4 configured as described above is attached to the frame 20 of the reel body 2 as shown in FIG. And as shown in FIG. 1, the cover member 25 is attached so that the part except the window part 52 and the switch part 55 among the counters 4 may be covered.

  Since the window part 52 is exposed from the cover member 25, the angler can visually recognize the information displayed on the display part 101 through the window part 52. Further, since the switch portion 55 is exposed from the cover member 25, the angler can press the switch portion 55 to switch the display on the display portion 101. In addition, it is preferable that the switch part 55 protrudes upwards rather than the cover member 25, for example.

[Counter case manufacturing method]
Next, a manufacturing method of the counter case 5 configured as described above will be described. First, the raw material of the window 52 is melted and injected into a mold to form the window 52.

  Subsequently, the window portion 52 is attached to the mold, and the case main body portion 51, the seal portion 54, and the raw material of the switch portion 55 are injected and injected into the mold, and the case main body portion 51, the seal portion 54 are injected. And the switch part 55 are formed. As a result, an integrally molded product including the case body 51, the window 52, the seal 54, and the switch 55 is completed. As described above, the counter case 5 is formed by a so-called multicolor molding technique.

  After the display unit 101 and the control board 102 are accommodated in the case main body 51 formed in this way, the bottom plate 53 is attached to the case main body 51 and the bottom surface of the case main body 51 is sealed. Thus, the counter 4 and the counter case 5 are completed.
