Abstract

A pointer including a thick section formed on a pointer body in a manner to be thicker than a thickness of the pointer body, an accommodation section provided in the thick section in a manner to penetrate through a front and back of the thick section, and a luminous member provided in the accommodation section.

First claim

What is claimed is:

1. A pointer comprising:
a thick section formed on a pointer body in a manner to be thicker than a thickness of the pointer body;
an accommodation section provided in the thick section in a manner to penetrate through a front and back of the thick section; and
a luminous member provided in the accommodation section,
wherein the thick section comprises a convex section projecting from a front surface of the pointer body and a concave section provided in a back surface of the pointer body in a manner to correspond to the convex section, and
wherein the accommodation section is provided penetrating through front and back surfaces of the thick section, by an opening section provided in the convex section and the concave section.

2. The pointer according to claim 1 , wherein the thick section comprises an opening section, and
wherein the thick section is formed on a leading end side of the pointer body.

3. The pointer according to claim 2 , wherein the thick section comprises a convex section projecting from a front surface of the pointer body and a concave section provided in a back surface of the pointer body in a manner to correspond to the convex section, and
wherein the accommodation section is provided penetrating through front and back surfaces of the thick section, by the opening section provided in the convex section and the concave section.

4. The pointer according to claim 1 , wherein the luminous member comprises a first luminous section and a second luminous section, and
wherein an area of the second luminous section is larger than an area of the first luminous section, in a planar view.

5. The pointer according to claim 2 , wherein the luminous member comprises a first luminous section and a second luminous section, and
wherein an area of the second luminous section is larger than an area of the first luminous section, in a planar view.

6. The pointer according to claim 1 , wherein the thick section is formed by half die cutting by which the pointer body is half punched in a thickness direction.

7. The pointer according to claim 2 , wherein the thick section is formed by half die cutting by which the pointer body is half punched in a thickness direction.

8. The pointer according to claim 1 , wherein a plurality of thick sections are provided in a plurality of areas of the pointer body.

9. The pointer according to claim 2 , wherein a plurality of thick sections are provided in a plurality of areas of the pointer body.

10. The pointer according to claim 1 , wherein the thick section is linearly provided along a longitudinal direction of the pointer body.

11. The pointer according to claim 2 , wherein the thick section is linearly provided along a longitudinal direction of the pointer body.

12. The pointer according to claim 1 , wherein the thick section has a surface subjected to a surface treatment.

13. The pointer according to claim 2 , wherein the thick section has a surface subjected to a surface treatment.

14. A timepiece comprising the pointer according to claim 1 .
