PROBLEM TO BE SOLVED: To suppress sliding bases from being displaced to one side in the moving direction. SOLUTION: Pushing-out mechanisms A2-A4 are dispersively arranged on both sides of the center line of the sliding bases 2-5 toward the moving direction of the sliding bases 2-5, and pulling-back mechanisms B2-B4 are dispersively arranged on both sides in the moving direction of the sliding bases 2-5.
