The surface finishing process with respect to the guide part 11 can be performed easily. In addition, the surface finishing process with respect to the guide part 13 of the counterweight guide rail 9 can also be performed easily.

  Further, since the finishing roller 26 is pressed against the guide parts 11 and 13, the surface finishing process can be performed while rolling the finishing roller 26, and the surface finishing process of the guide parts 11 and 13 can be performed efficiently. .

  In addition, each recessed part 33 may be a groove | channel arrange | positioned along the moving direction of a sliding member. In this case, each groove is formed on the surfaces of the guide portions 11 and 13 by, for example, a planing process before the surface finishing process. If it does in this way, supply of lubricating oil between a sliding member and guide parts 11 and 13 can be made still more reliable, and smooth movement to guide parts 11 and 13 of a sliding member will be realized more certainly. can do.
