Abstract

PURPOSE: To smooth relative movement between a nut and external thread, by constituting the nut of a ball screw with ball containing plural through holes, circularly hollowed cylindrical body and springy circular retainer closely contacted to the periphery of said cylindrical body.
CONSTITUTION: A nut is constituted in such a manner that an external thread 2 is inserted into the insertion hole 1a of a cylindrical body 1 and balls 3 are inserted into through holes 1b in the periphery of the cylindrical body 1 further a springy circularly hollowed retainer 4 is closely fitted to the periphery of the cylindrical body 1 Said cylindrical body 1 is formed in such a manner that the insertion hole 1a constituted by its hollowed part is formed to an inside diameter insertable for the external thread 2 further the plural through holes 1b drilled in the peripheral side are correspondingly formed so as to be along the center of a groove 2a in tje external thread 2 with a prescribed interval apart. In this constitution, relative movement between the nut and external thread can be smoothed and facilitated, simultaneously they can be easily manufactured further at low cost.
