給してなるものである。(Prior Art) A pointer that causes a pointer portion of a meter to emit light is widely known. The basic configuration is that the pointer body is made of a light guide material (transparent plastic body), the light guide plate is arranged on the back side of the instrument dial, and the light from the light source is guided to the pointer body through the light guide plate. It shines. As shown in Japanese Utility Model Publication No. 58-13694, the light-transmitting means (pointer shaft) of the pointer body is projected to the back surface of the dial plate to transmit light between the light guide plate and the pointer body. 58-13693, which irradiates the projecting portion with light from the end face of the light guide plate surrounding the projecting portion.
As shown in the publication, the end face of the guide shaft insertion hole of the light guide plate is formed obliquely, the inclined surface reflects light to irradiate the dial plate surface side, and the light passing through the light guide plate is guided by the pointer body. It is supplied to the light receiving section.

報）。Further, in the case where the inclined surface of the light guide plate is used, the light emitted from the light guide plate to the dial plate surface side is reflected by the bottom surface of the light receiving portion of the pointer body, so that the periphery of the dial shaft hole of the dial plate becomes bright. There is a problem that halation occurs or the incident light on the pointer becomes uneven and only a specific part of the pointer shines remarkably.Therefore, the light from the light guide plate is incident on the bottom side of the light receiving part of the pointer. What is called a seat that shuts off a part of the is used (Japanese Utility Model Publication Nos. 1-99019 and 1-148817).

されている。Further, the cap body is formed of plastic, and burrs are formed on the outer peripheral lower end surface portion of the cap body as a joint between the upper and lower molds during resin molding. Therefore, a part of the light that is not reflected from the inclined surface of the light guide plate to the pointer portion on the dial plate surface side irradiates the burr portion and diffusely reflects there, so that the lower end portion of the cap body looks white (FIG. 2). (See (a)). As a countermeasure against the above, Japanese Utility Model Publication No. 62-39291 proposes to provide a chamfered portion at the lower end portion of the cap body.

It is an attempt to solve the problem of burr of the cap body without using any means.

In the instrument pointer that self-luminesce by receiving light from the light guide plate on the back face of the dial, the seat body is molded such that the lower edge of the outer periphery is the location where burrs do not occur. And the seat body is positioned such that the seat body outer peripheral lower end position is lower than the cap body outer peripheral lower end and retracted toward the center of rotation of the pointer, and blocks light from the light guide plate to the cap outer peripheral lower end. It is characterized in that it is provided at a position.

As shown in FIG. 7, since it is blocked at the outer peripheral lower end portion of the seat body, diffused reflection does not occur at the burr portion of the cap body. Also, since the lower edge of the outer periphery of the seat body is a location where burr does not occur during molding, diffuse reflection does not occur at that location, and even if halation occurs at that location due to inconvenience during molding, it recedes from the cap body to the center of the pointer. And is covered with a cap body.
（実施例） 次に本案の実施例について説明する。(Example) Next, an example of the present invention will be described.

座体２及びキャップ体３を一体化してなるものである。The instrument pointer according to the embodiment of the present invention is composed of a pointer body 1, a seat body 2 and a cap body 3, and the pointer body 1 is made of a transparent acrylic resin, and includes a pointer portion 11 and a base portion (light receiving portion) 12. Therefore, a balance weight 13 is attached to the base 12 and is mounted and mounted on the seat body 2. The seat body 2 is provided with a light shielding plate portion 21 on the upper portion thereof and a connecting portion 23 having an insertion hole 22 for inserting a pointer shaft on the lower portion thereof, and a paragraph portion 24 for mounting a cap body on the outer peripheral portion of the light shielding plate portion 21. Is provided. The cap body 3 is the base portion 12 of the pointer body 1.
In a shape that covers the pointer body 1,
The seat body 2 and the cap body 3 are integrated.

認されるようなこともない。Thus, when the pointer is mounted on the instrument, the reflected light from the inclined surface B 1 of the light guide plate B arranged on the back surface of the dial A passes through the exposed surface around the shaft through hole A 1 of the dial A. Base of body 1
It is incident on 12 and diffused on the surface of the pointer portion 11 of the pointer body 1 to cause the pointer portion 11 to shine. When the light is reflected from the inclined surface B 1 of the light guide plate B, the light reaching the inclined surface B 1 at a critical angle or less determined by the material of the light guide plate B is not reflected but is transmitted as it is. Proceed to. Therefore, burrs generated when the seat body 2 and the cap body 3 are formed are formed on the outer peripheral portion a of the paragraph 24 of the seat body 2 and on the lower end outer peripheral portion b of the cap body 3, respectively. The position of c is the outer peripheral portion b of the lower end of the cap body 3.
It is provided at a correspondingly lower position and at a position for blocking the above-mentioned transmitted light toward the lower end outer peripheral portion b of the cap body 3. For this reason, the above-mentioned transmitted light is the outer peripheral lower end portion c of the seat body 2.
Is blocked by and does not reach the burr parts a and b. Also seat 2
The outer peripheral lower end portion c becomes the cavity side at the time of molding, and the surface is smooth and diffuse reflection of transmitted light does not occur. Therefore, the lower portion of the pointer cap does not become bright. In addition, the outer peripheral lower end portion c of the seat body 2 is a lower end outer peripheral portion b of the cap body 3.
Since the outer peripheral lower end portion c, which becomes the boundary for light shielding, is hidden by the cap body 3 and cannot be seen from the outside, halation or the like occurs at the outer peripheral lower end portion c due to inconvenience during molding. Even if such unnatural light occurs, the unnatural light is hidden by the cap body 3 and is not visually recognized.

用できる。In this case, the specific shapes of the pointer body 1, the seat body 2, and the cap body 3 and the means for integrating the three members can be arbitrarily determined as long as the transmitted light is blocked by the seat body 3. It is a thing. The light emitting mode of the pointer body 1 is a type only on the tip side of the pointer portion 11 excluding the cap body 3, a type in which the light emitting surface is inserted up to the middle of the cap body 3 (this embodiment), and the light emitting surface crosses the cap body. It can be applied to all types such as types.

である。(Effects of the Invention) As described above, the present invention exposes the pointer body formed of the light guide material, the cap body that covers the light receiving portion of the pointer body, and the bottom surface of the light receiving portion of the pointer body so that light is received by other portions. In the instrument pointer, which is composed of a seat body that shuts off and self-luminesces when receiving light from the light guide plate on the back face of the dial, the seat body is formed by molding such that the outer peripheral lower end portion is a burr-free portion, The seat body is provided at a position where the lower end of the outer periphery of the seat body is lower than the lower end of the outer periphery of the cap body and retracts toward the center of rotation of the pointer, and the light is blocked from the light guide plate to the lower end of the outer periphery of the cap body. As a result, it is possible to prevent the peripheral end face of the cap body from becoming bright without using a complicated means for performing special processing on the burr generation position of the cap body, and at the outer peripheral lower end portion of the seat body due to inconvenience during molding. Unnaturalness such as halation Even if light is generated, the unnatural light is hidden by the cap body, and the unnatural light can be suppressed from being visually recognized from the outside.
