PROBLEM TO BE SOLVED: To provide a pillow ball bush for a remote control mode capable of not only assembling a pillow ball and a ball end together rapidly, unfailingly and efficiently without causing any damage but also fairly adjusting a gap between a convex portion and the spherical surface of a hole fitting onto the same by properly expanding the pillow ball even when it shows wear and tear at the time of use due to abrasion. SOLUTION: The pillow fall bush is composed of a slightly elastic cylindrical pillow ball 22 having a spherically convex portion 3 formed on the outer peripheral surface of the same along the circumference thereof and a ball end 5 slidably fitted onto the convex portion 3 of the pillow ball 22 at the spherical fitting hole 6 thereof. The pillow ball 22 has at least a slit 33 formed along the longitudinal direction thereof. |
