In the publication, a light guide body serving as an index portion is uniformly formed of an acrylic resin or the like, and this is integrally assembled with an operation knob. In this case, since the light guide needs to ensure visibility in the daytime,
In general, it is often molded with a pale milky resin,
There is a problem that light passing through the light guide gradually attenuates toward the front and visibility at night is reduced. Conversely, if the indicator is molded in a color with high light transmittance and close to transparency in order to increase nighttime visibility, there is a contradictory property that daytime visibility will decrease, so that Improvement was desired.

Is a disk-shaped knob main body, which is formed of a dark synthetic resin such as black, and has a hollow rotary cylinder 2 integrally formed at the center thereof and protrudes rearward.

入されている。A circular fitting hole 3 is opened at the peripheral end of the front surface of the knob body 1, and a fitting hole 4 having a rectangular cross section having a larger diameter than the hole 3 is formed in the deep part. The light guide 5 is press-fitted into these fitting holes 3 and 4.

a is formed, and a cylindrical shaft cylinder portion 6 that can be press-fitted into the fitting hole 3 protrudes from the front end thereof.

The visibility described later can be adjusted by adjusting the density of the milky white color and the length in the axial direction.

ことも可能である。In this case, instead of forming the light guide 5 in two colors as described above, the indicator 6a is formed by silk printing, painting, hot stamping or the like, or by making full use of aluminum vapor deposition and hot stamping. It is also possible to prepare a so-called magic mirror-like foil and attach it to the front end of the shaft cylinder 6 as the indicator 6a. In the latter case, since the indicator 6a transmits only light from behind and does not transmit light from the front, the indicator 6a exhibits a metallic color during the day and an illumination color during the night. Further, instead of forming the index portion 6a into a dark milky white color, it is also possible to form the indicator portion 6a into a translucent color having a light transmittance lower than that of the light guide 5.

よってもよい。In FIG. 1, reference numeral 7 denotes a light source arranged behind the operation knob 1, which is arranged so as to be able to enter the reflecting surface 5a. In addition,
In the embodiment, the press-fitting method is adopted as a means for assembling the light guide 5, but other methods such as insert molding or bonding may be used.

導光体５をノブ本体１の後方から嵌合孔４に押し込み、
更に軸筒部６を嵌合孔３に押し込んで、指標部６ａの先
端部をノブ本体１の前面に位置付ければよい。In the transmission illumination structure of the operation knob configured as described above, the knob main body 1 and the light guide 5 may be separately formed, and these may be assembled integrally. When assembling,
The light guide 5 is pushed into the fitting hole 4 from behind the knob main body 1,
Further, the shaft cylinder 6 may be pushed into the fitting hole 3 so that the tip of the index portion 6 a is positioned on the front surface of the knob body 1.

近接位置に光源７が配置される。The operation knob thus assembled is incorporated at a predetermined position of an air conditioner display section of, for example, an instrument panel of an automobile, an operation shaft (not shown) is attached to the rotary cylinder 2, and a light source 7 is disposed at a position close to the operation shaft.

よって、指標部６ａの位置を明瞭に視認できる。The operation knob incorporated in this way is
The knob main body 1 is located on the front of the operation unit, and the index unit 6a is located on the front of the main body 1. Since the index portion 6a is dark milky white and the knob body 1 has a dark color such as black, the position of the index portion 6a can be clearly recognized by the brightness contrast even in a bright daytime environment.

６ａに到達したところで、その光を外部へ放射する。On the other hand, in the nighttime when the surroundings are dark, the visual recognition of the index portion 6a is mainly based on the transmitted light from the light source 7. That is, the light radiated from the light source 7 passes through the rear end of the light guide 5 and enters the reflection surface 5a. After being reflected by the portion, the optical axis is directed forward as shown by the arrow in FIG. When the light moves inside the light guide 5 and reaches the index portion 6a, the light is emitted to the outside.

間の最適視認性を形成する従来のものと相違している。In this case, since the light guide 5 is composed of a transparent light-transmitting member, the light traveling inside the light guide 5 is attenuated at all, and is attenuated only after reaching the index portion 6a. To form the optimal visibility at night. This situation is as shown in FIG. 4, which is different from the conventional one in which the inside of the light guide 5 continues to be attenuated when moving and forms the optimum visibility at night.

This relationship is shown in FIG.

Property can be sufficiently secured. Further, since the light transmittance of the index portion is lower than that of the light guide, there is a practical effect that the index portion can be clearly recognized in the daytime.
