大するという問題があつた。(Prior art and its problems) The bearing of the pointer shaft of a conventional vehicle instrument, such as a speedometer, is an annular bearing with a screw hole drilled in the top plate of the instrument body and a screw threaded on the outer circumferential surface. One end of the pointer shaft is rotatably supported in the center hole (bearing hole) of this bearing. However, with such a structure, it is necessary to perform post-processing such as caulking after screwing in order to eliminate play in the meshing part between the screw hole of the body and the screw of the bearing, which requires a large number of man-hours. During mass production, there was a problem in that variations in the accuracy of the connection between the body and the bearing increased.

果を有する。(Effects of the invention) As detailed above, the bearing of the pointer shaft in the vehicle instrument of the present invention consists of the body of the instrument consisting of an underbody and an atsupa body that is bonded and fixed to the underbody, and the atsupa body is made of a resin member. A metal bearing with a non-rotating outer circumferential surface is integrally fixed at a predetermined location on the upper part of the Atsupa body, the upper end of the pointer shaft is inserted into the bearing and supported, and a collar is attached to the upper end. Since the upper end of the pointer shaft is rotatably suspended from the atsupa body by press-fitting, the bearing is made of metal, and since this metal bearing is held between the pointer shaft and the collar, it is not possible to use conventional resin. The pointer can rotate smoothly without the characteristic creep deformation that occurs with steel bearings.Since the resin attachment body is used and the metal bearing is fixed to it by integral molding, no special mounting means are required. This simplifies the configuration, reduces assembly man-hours, and improves the accuracy of the connection between the body and pointer bearing because there is less variation between products even during mass production. Since the fitting between this and the bearing on the underbody side is done in the final process of assembly, fitting of the pointer shaft to the bearing on the underbody side can be easily done, and automatic assembly is easy. This has effects such as improved productivity and reduced costs.
