PROBLEM TO BE SOLVED: To provide a tape lap device for processing a rotary surface capable of finishing the surface of a processed surface to be rotated with a peripheral-speed difference between an inner periphery and an outer periphery into an even surface without a pressurizing pressure adjusting mechanism for changing an abrasive material-coated tape pressurizing pressure at the inner periphery and the outer periphery. SOLUTION: An abrasive material-coated polyester tape is used as a comparatively non-compressive abrasive material-coated tape 1. A rigid surface has hardness exceeding a value of a 90 durometer A as a shoe assembly 5 having a comparatively rigid tip face for bringing the tape into contact with a surface 3 of a workpiece 2 and pressurizing it. Also, the shoe assembly 5 having the tip face 4 using an insert stone formed of a precisely processed horning grinding-stone is used. The tip face 4 of the shoe assembly 5 is inserted in two holes 35, 35' (three or more holes) radially separated from the surface 3 of the workpiece, which is a processed face to be rotated, and is supported by pistons 36, 36' energized by springs 37, 37'.
