PROBLEM TO BE SOLVED: To provide a picker member having the large displacement in the radial direction, commonly usable for a plurality of kinds of bobbins of different inside diameters, and capable of enhancing the durability. SOLUTION: The picker member 20 to be inserted in a bobbin B has a plurality of tight contact portions 23 which are arranged in an inner circumferential direction of the bobbin B with a gap between the adjacent tight contact portions and which are displaceable in a radial direction of the bobbin B between a reduced diameter state and an increased diameter state in which the tight contact portions widen out in the radial direction compared to the reduced diameter state, and a coupling portion 24 that couples the plurality of tight contact portions 23 together.
