。Background Art A mechanism that rotates a straight round bar (hereinafter referred to as a round bar) and moves a piece penetrated by the round bar relatively along the round bar. The so-called screw-nut mechanism has threads of the same pitch cut into the circular hole in the valve body.
A so-called linear pole screw mechanism is used, in which spiral grooves with the same pitch are bored in the round bar and the white round hole in the single body, and balls that can be circulated by a circulation mechanism installed in the single body are connected between both grooves, or they are attached to the single body. Various mechanisms have been discovered, including tilted bearings and rollers pressed against a round bar. In either case, when the round bar rotates one of the pieces while restricting the rotation of the other, the piece and the round bar move relative linearly along their axes.
