PROBLEM TO BE SOLVED: To provide a puller naturally corresponding to pulled bodies of various dimensions and safely and smoothly remove without damaging the pulled bodies. SOLUTION: This puller has a pressure plate device 10 set within a flat surface crossing the working direction of tensile force on a working end of the tensile force, the pressure plate device 10 is constituted of three pieces of plates 11 with arc-shaped inner peripheral edges arranged on the same circumference and three pieces of connecting rods 12 to connect the adjacent plates 11 to each other, a projected part 111 is formed by bending an inner edge part of the plate 11 in a hook shape in the pulling direction, through-holes 112 are formed on both sides of an outer peripheral part of the plate 11 respectively and the connecting rod 12 is inserted into the through-hole 112 to corresponding the adjacent plates 11 free to slide and fix.
