  Returning to FIG. 2, the sealing material 190 is a thin strip-shaped sealing material formed in a ring shape surrounding the outer peripheral portion of the front surface of the light guide body 171, and each seal of the light guide body 171. An engaging portion 191 made up of a small hole into which the seal material positioning portion 181 is inserted is provided at a position facing the material positioning portion 181. For example, silicon rubber or the like is used as the material of the sealing material 190.

  FIG. 8 is a perspective view of the cover 210 as seen from the rear side. As shown in FIG. 2 and FIG. 2 and the like, the cover 210 is a molded product of synthetic resin, and is formed in a rectangular box shape with the rear surface side opened, and the recess formed on the rear surface side covers the front surface of the apparatus main body 150. The main body insertion portion 211 has a dimension and shape that covers (inserts). The cover 210 prevents light from passing through by applying a light-impermeable coating to the entire outer surface of the transparent synthetic resin molded product, and at the same time, on the portion facing the light irradiation surface 185 of the light guide 170. The arc-shaped light display portion 213 that allows light to pass by not applying the paint is formed. The cover 210 may be made of a light-transmitting synthetic resin, and the light display portion 213 may be configured to transmit light through the through-hole.

  A front surface of the cover 210 is provided with a pair of insertion holes 215 through which the pair of knobs 105 and the shaft 103 are inserted, and the rear surface side of the insertion hole 215 (inside the main body insertion portion 211) surrounds it. A protruding portion 217 protruding in a cylindrical shape is formed. In addition, a pair of rectangular insertion portions 219 each having a through hole into which a display portion 251 of a light guide member 250 described below is inserted is formed in the lower portion near the left and right ends of the front surface of the cover 210. A pair of rectangular drain holes 221 each having a through hole are formed on the upper and lower surfaces of the cover 210. Each drain hole 221 is installed in the vicinity of the tip of each projection 217. Locked portions 223 each having a rectangular opening are formed at the rear end portions of the left and right sides of the cover 210. In addition, light shielding portions 225 that cover the periphery of the rear surface side of the insertion portion 219 are formed on the left and right outer sides of the protrusions 217 in the main body insertion portion 211 of the cover 210. The light shielding part 225 is formed in the main body insertion part 211 so that light does not leak between the space on the rear surface side of the insertion part 219 and the other space. Further, a sealing material abutting portion 227 is provided on the inner peripheral side wall of the main body insertion portion 211 of the cover 210 so as to surround the inner peripheral side wall over the entire circumference. The sealing material abutting portion 227 is formed by a stepped surface provided by making the front side surface higher than the rear side surface of the inner peripheral side wall of the main body insertion portion 211.

  Returning to FIG. 2, the light guide member 250 is a molded product of a transparent synthetic resin, and is formed in a shape that is substantially rod-shaped (substantially a quadrangular prism) and bends by 90 degrees in opposite directions at two intermediate positions. Yes. A display portion 251 to be inserted into the insertion portion 219 of the cover 210 is provided on the front end surface of the cover 210, and a lower surface portion of the rear end is a light incident portion 253. Reflecting surfaces b1, b2, and b3 that are obliquely inclined with respect to the light incident direction are provided on the upper surface of the rear end where the light incident portion 253 is provided and the two corners that are bent.

  Next, an example of a method for assembling the seat heater operating device 1 will be described. First, in FIG. 3, the circuit board 50 to which the light emitting element 53 and the rotary electronic component 100 (with the knob 105 not attached) and the like are attached is housed in the upper case 10 from the lower surface side. At that time, the shaft 103 of each rotary electronic component 100 is inserted into the shaft penetration portion 11 of the upper case 10. 3 and FIG. 5 is inserted from the lower surface side of the circuit board 50 and protruded to the upper surface side, and the screw portion 21 is a column-shaped screw mounting portion 21 depending from the upper surface of the upper case 10. Both are integrated by screwing into the central hole. Further, the nut 23 is screwed and fixed to the screw portion 107 at the tip of the electronic component main body 101 of the rotary electronic component 100 protruding forward from the upper case 10.

  Next, the lower case 30 is installed on the lower surface side of the circuit board 50. At that time, the locking portion 33 of the locking arm portion 35 of the lower case 30 is connected to the locked portion 19 of the upper case 10 from the inside. The upper and lower cases 10 and 30 are fixed by locking. Thereby, the apparatus main body 150 shown in FIG. 2 is completed. At this time, as shown in the figure, the pair of light emitting element protrusions 55 of the circuit board 50 protrude forward from the front surface M1 of the upper and lower cases 10 and 30.

  Next, the light guide 170 is installed on the front surface M of the upper and lower cases 10 and 30. At this time, the shaft 103 is inserted into each shaft penetration portion 177 of the light guide 170, and the side wall portion 172 of the light guide body 171 is inserted into the outer periphery of the light guide attachment portion 15 of the upper case 10. At this time, the light introduction part 175 of the light guide 170 is inserted into the case from the light introduction part insertion part 13 of the upper case 10, and the lower surface of the tip part is the light emitting element 53 as shown in FIG. 4. Opposite to. Further, the light emitting element projection 55 of the circuit board 50 projects forward through the recess 183 of the light guide 170.

  Next, the knob 105 is attached to the tip of each shaft 103 protruding from the light guide 170. Next, the seal member 190 is installed so as to surround the outer periphery of the front surface of the light guide 170, and at that time, each sealing material positioning portion 181 of the light guide 170 is inserted into each locking portion 191 of the sealing material 190. Position and temporarily fix.

  Next, the display unit 251 of the light guide member 250 inserted and fixed to each insertion part 219 of the cover 210 is inserted so as to cover the front side of the light guide 170, and each cover 210 of the cover 210 is inserted. Each locking part 17 of the upper case 10 is locked to the locking part 223. Thereby, the assembly of the seat heater operating device 1 is completed. The above assembling procedure is an example, and it goes without saying that the assembly may be performed using other various assembling procedures.

  In the assembled seat heater operating device 1, the sealing material 190 contacts the sealing material contact portion 227 of the cover 210, and the sealing material 190 is sandwiched between the light guide body 171 and the sealing material contact portion 227. The light irradiation surface 185 of the light guide 170 is located close to the back surface side of the light display portion 213 of the cover 210. Further, the light incident portion 253 of each light guide member 250 is positioned close to the upper portion of the indicator light emitting element 57. The light guide member 250 is housed in the light shielding portion 225 of the cover 210.

  The seat heater operating device 1 configured as described above is for in-vehicle use, and when installed in the vehicle, only the front surface portion (the surface on which the knob 105 is exposed) of the cover 210 is exposed to the inside of the vehicle.

  In the state shown in FIG. 1, when any of the knobs 105 is rotated, the shaft 103 is rotated, the mechanical part in the electronic component main body 101 is operated, and the resistance value is changed. When another switch (not shown) is turned on, the indicator light emitting element 57 is turned on, and the light enters the light guide member 250 vertically from the light incident portion 253 shown in FIG. 2 and is reflected by the reflection surfaces b1, b2, and b3. Thus, the display unit 251 that is guided to the display unit 251 and exposed on the front surface of the cover 210 can be displayed brightly. At this time, since the light shielding part 225 is provided in the cover 210, the light leaking from the light guide member 250 does not illuminate the light display part 213 of the cover 210.

  On the other hand, when the night illumination of the vehicle is performed, the pair of light emitting elements 53 attached to the circuit board 50 emit light, most of the light is directed directly above, and from the lower surface near the tip of the light introducing portion 175 of the light guide 170. Light enters the light introduction part 175 perpendicularly, is reflected by the front reflection surface a 1, travels forward through the light introduction part 175, and then is reflected by the upper light reflection surface a 2 of the light guide front part 179. 179 is directed upward, and then reflected by the left and right light reflecting surfaces a3 and introduced from the light guiding front surface portion 179 into the illuminating portion 173, and this light is further guided through the illuminating portion 173 to its tip. The back surface side of the light display unit 213 of the cover 210 is illuminated from the irradiation surface 185, whereby the arc-shaped light display unit 213 can be illuminated brightly.

  Here, for example, when spilling drinking water or the like in a cup in a car and the liquid enters the inside of the device from between the insertion hole 215 of the cover 210 and the knob 105 (shaft 103), as shown by an arrow in FIG. , Most of them flow backward on the bottom surface in the protrusion 217 of the cover 210 and go from the tip to the drain hole 221 located directly below, most of which is discharged from the drain hole 221 to the outside. . When a large amount of water enters, the water passes through the drain hole 221 and reaches the light guide body 171 of the light guide 170. This portion is a seal sandwiched between the light guide 170 and the cover 210. Since it is sealed by the material 190, this liquid is prevented from entering the front surface M1 side of the upper and lower cases 10, 30. Although there is a gap between the shaft penetrating portion 177 and the shaft 103 of the light guide 170, as described above, most of the liquid that has entered the insertion hole 215 is located on the bottom surface in the protruding portion 217 of the cover 210. Since they are collected and flow backward on the bottom surface, liquid does not normally enter from the gap at a position floating in the air above (the center position of the insertion hole 215). In the case of the seat heater operating device 1, since the drain holes 221 are provided on the upper and lower surfaces of the cover 210, the ventilation is good and the drying of the liquid attached to the inner surface between the cover 210 and the light guide 170 is effective. Can also be done.

  In other words, in the case of this seat heater operating device 1, the portion surrounding the entire periphery of the insertion hole 215 of the cover 210 is sealed by the sealing material 190, and therefore, other than the gap between the shaft penetrating portion 177 and the shaft 103 of the light guide 170. The liquid does not enter the front surface M1 side of the upper and lower cases 10 and 30 from this portion. In addition, although not shown in the figure, when a more complete waterproofing is desired, a seal member for closing the gap between the shaft penetrating portion 177 and the shaft 103 is separately attached, or other waterproof means is provided for the gap. What is necessary is just to provide.

  As described above, the seat heater operating device 1 allows the light guide body 170 to have both the light guide function and the drip-proof function, and at the same time, the light guide body 170 is provided with the illumination unit 173 and the light introduction unit 175. Since the rotary electronic component 100 and the light emitting element 53 can be mounted on the same circuit board 50, it is not necessary to install a plurality of circuit boards 50, and at the same time, a drip-proof component is mounted separately. There is no need. Thereby, in the seat heater operating device 1 having both the illumination function and the drip-proof function, it is possible to reduce the number of parts, simplify the device structure, reduce the cost, and reduce the size of the device.

  Further, by using the sealing material 190, it is possible to more effectively prevent the liquid that enters from the insertion hole 215 of the cover 210 from entering the upper and lower cases 10 and 30. Further, the plate-like light guide body 171 provided on the light guide body 170 prevents liquid from entering the front surface M1 side of the upper and lower cases 10 and 30, but using this light guide body 171, The light from the light introduction part 175 can be easily guided to the illumination part 173 having a different height in the horizontal direction only by providing the light guide front part 179 having a thicker thickness on the front side.

  Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications can be made within the scope of the technical idea described in the claims and the specification and drawings. Is possible. Note that any shape, structure, or material not directly described in the specification and drawings is within the scope of the technical idea of the present invention as long as the effects and advantages of the present invention are exhibited. For example, in the light guide 170, the shape of the light guide body 171 is formed in a substantially flat rectangular shape. However, the shape and structure can be variously changed, and in most cases, the light guide body 171 enters from the insertion hole 215 of the cover 210. Any shape or structure may be used as long as it is drip-proof to prevent the liquid to reach the front surfaces of the upper and lower cases 10 and 30. It goes without saying that various changes can be made to the shape of the illumination part 173 and the light introduction part 175 and the direction in which the light guide body 171 protrudes. Further, the sealing material 190 is formed so as to surround the entire periphery of the insertion hole 215 of the cover 210. However, the sealing material 190 may be installed only in a part of the portion that is necessary instead of the entire periphery. Furthermore, the seal material 190 may be omitted when drip-proofing can be achieved by other methods such as direct contact between the light guide 170 and the cover 210.

  In the seat heater operating device 1, a rotary variable resistor is used as the rotary electronic component 100. However, other various rotary electronic components such as a rotary switch may be used. Furthermore, the present invention may be a push switch that only moves in the pressing direction without rotating the shaft. In short, an electronic component having any function may be used as long as it has a shaft and its output signal is changed by operating the shaft. Furthermore, although the seat heater operating device 1 has been described as an example of the operating device according to the present invention in the above embodiment, the present invention is not limited to the seat heater operating device, and can be similarly applied to other various operating devices.
