Claims

[Claims for Utility Model Registration] 1. A shaft hole 31 having a base notch S1 and tip notches S2, S2 for fitting the spring 4 into the bearing part 3 is provided, and a base notch S is provided.
1 has a base support piece 32, a tip notch S2,
In S2, support pieces 33, 33 for the tip are formed on the surface of the bearing hole 31, respectively, and consist of a base 41, shaft clamping parts 43, 43, and tip parts 42, 42, and the distance C between both tip parts is A substantially U-shaped spring 4, which is smaller than the corresponding distance D between the inner surfaces f2 and f2 of both tip ends S2 and S2, is expanded and fitted into the bearing hole 31, and by inserting the rotation shaft 21, the spring is inserted into the shaft. A rotary shaft braking device that generates a braking force by spring force in the mounting portions 43, 43. 2 The notches S2, S2 for the tip end are formed on each inner surface f2,
The circuit according to claim 1, wherein f2 imparts a self-retaining action to the tip of the spring 4, and each outer surface f1, f1 regulates the expanded state of the tip of the spring when the rotation shaft is assembled. Dynamic shaft braking device. 3. The rotating shaft braking device according to claim 1, wherein the shaft clamping portion 43 of the spring is a curved surface portion having an inner surface radius of curvature R1 smaller than the rotating shaft radius of curvature R2.
