A ball screw in which a nut and a male-threaded shaft provided with an arcuate continuous groove threadedly engage by way of a multiplicity of steel spheres inserted between the male threads and female threads, the end portion seal member is capable of being attached toward a front or toward a back from said nut, and has a support frame body arranged at an outside circumference of said male-threaded shaft; a base fabric portion, a back surface of which is secured to an inside circumferential surface of said support frame body; and the cut pile that protrudes in such fashion as to be directed toward said groove from a front surface of said base fabric portion; wherein fiber tip portions of said cut pile are bent and made to abut said groove so as to occlude a gap between said groove and said support body, and good lubricant is retained.

Provided is a cable holding tool capable of reducing a size of a gap formed at a portion where soft members are sandwiching a cable to thereby increase air-tightness thereat. First sealing members () having fluffs are attached to a first opposing surface of a soft member (). Second sealing members () having fluffs are attached to second opposing surfaces of soft members (). When a cable () is sandwiched between the first sealing members () and the second sealing members (), the fluffs of the first sealing members () and the fluffs of the second sealing members () are in contact with each other.
