Claims

[Scope of utility model registration request]

(1) Frictional restraint with a frictional engagement part provided between the master disk attached to the base and the shaft end that rotatably penetrates the master disk, which comes into pressure contact when the shaft end is pressed against the master disk and is activated. In the device, locking pieces 4 protruding from both ends of the C-shaped leaf spring 3 to the outside of the C-shaped leaf spring 3 are engaged with grooves formed on the back surface of the master 1 to sandwich the shaft end 2. The central part of the C-shaped leaf spring 3 is cut and raised on the outside of the C-shaped leaf spring 3 so that the shaft end 2 protruding to the back side of the master disk passes through, and a threaded groove is formed in the shaft end. Alternatively, a pair of left and right inclined protrusions 5 are provided whose tips are press-fitted to the annular groove, and when the tips of the two oblique needle protrusions engage with the threaded groove or the annular groove, the C-shaped leaf spring 3 is compressed. A friction restraint device for a rotatable shaft end, which is configured to be

(2) In the friction restraint device for a rotatable shaft end described in claim (1) of the utility model registration, the tip of the inclined protruding piece 5 engages with a threaded groove or annular groove carved in the shaft end. The portion is formed into a V-shaped notch 5a.
