生じる操作上の円滑さが欠ける不都合があった。According to the present invention, since the existing long power rail is made of iron and the screw shaft is arranged outside the rail along the rail, the whole cross section becomes large. Therefore, there is an inconvenience that the structure cannot be made compact, and when the outer screw shaft is built into the long rail, the long screw shaft may cause a large runout and interfere with the rail or the like. This may cause abnormal noise and vibration, and in existing long rails, steel balls, rollers, etc. are generally used as sliding parts, which is not only inconvenient to assemble but also causes operational rattling. There was a lack of inconvenience.
