中して簡単に折れてしまうという問題があつた。Conventional structure and its problems Conventionally, spindles were made by cutting metal, but the manufacturing costs such as processing costs and surface treatment were high, which was one of the obstacles to supplying inexpensive automatic record playing devices to the market. It was hot. As a way to improve this problem, research has been progressing in recent years to replace the metal spindle with a resin molded product, but the spindle is the first
As shown in Fig. 2, the cylindrical part 1 requires a long groove 6 for storing the record keeper 4, feeder 5, etc., and the neck part 3 is thinner, and if the metal is replaced with resin molding as it is, the strength will be increased. The problem was that it was getting weaker. Furthermore, in conventional products, the connecting part between the record loading surface 2 and the neck part 3 is formed with an edge or a very small roundness, and when force is applied in the direction of the arrow, stress concentrates on this connecting part, making it easy to I had a problem with it breaking.
発明の目的
本発明はこのような従来の欠点を解決し、首部

折れるのを防止することを目的とする。OBJECTS OF THE INVENTION The present invention aims to overcome these conventional drawbacks and prevent the spindle from breaking by preventing stress concentration on the neck.

る。Structure of the Invention The present invention provides a resin-made spindle for continuous record playback used in an automatic record playback device, in which the connecting portion between the neck-shaped portion of the record loading surface and the cylindrical portion of the spindle is formed in a concave shape relative to the record loading surface, and the corner thereof The part is rounded. If the corner portions are rounded in this way, the roundness can prevent stress from concentrating on the neck.

とである。DESCRIPTION OF THE EMBODIMENTS FIGS. 3 and 4 show an embodiment of the present invention, in which the same components in FIGS. 1 and 2 are denoted by the same reference numerals. Here, Fig. 1, Fig. 2
The difference from the one in the diagram is that a recess 7 is provided so that the connection between the record loading surface 2 and the neck 3 is lower than the record loading surface 2, and a roundness 8 is provided at the corner to connect it to the cylindrical portion 1. This is what I did.
