A wire winding device configured to wind a wire onto a winding drum of a reel and lock a pulled-out part of the wire to a clip of the reel, the pulled-out part being pulled out from a wound part of the wire, the clip including a base end portion and a tip end portion, the base end portion being supported by an inner surface of a first flange of the reel and located at an inner circumferential side in a radial direction, the tip end portion being located at an outer circumferential side in the radial direction, an interval between the tip end portion and the inner surface being changed by elastic deformation of the clip using the base end portion as a fulcrum, the wire winding device comprising: a reel driving portion configured to rotate the reel; a wire feeding portion configured to supply the wire to the reel while applying tension to the pulled-out part; a lock jig including a pair of tip end portions (51a, 52a) configured to approach each other or separate from each other; a lock jig driving portion configured to make the lock jig move and make the pair of tip end portions (51a, 52a) of the lock jig approach each other or separate from each other; and a control portion, wherein: the control portion is configured to execute a step of controlling the reel driving portion and the wire feeding portion to wind the wire onto the winding drum, and a step (S12, S13, S16) of controlling the lock jig driving portion to make the lock jig sandwich the pulled-out part, insert the lock jig between the clip and the inner surface, and open the tip end portions (51a, 52a) of the lock jig against biasing force of the clip to open the clip. the clip including a base end portion and a tip end portion, the base end portion being supported by an inner surface of a first flange of the reel and located at an inner circumferential side in a radial direction, the tip end portion being located at an outer circumferential side in the radial direction, an interval between the tip end portion and the inner surface being changed by elastic deformation of the clip using the base end portion as a fulcrum, the wire winding device comprising: a reel driving portion configured to rotate the reel; a wire feeding portion configured to supply the wire to the reel while applying tension to the pulled-out part; a lock jig including a pair of tip end portions (51a, 52a) configured to approach each other or separate from each other; a lock jig driving portion configured to make the lock jig move and make the pair of tip end portions (51a, 52a) of the lock jig approach each other or separate from each other; and a control portion, wherein: the control portion is configured to execute a step of controlling the reel driving portion and the wire feeding portion to wind the wire onto the winding drum, and a step (S12, S13, S16) of controlling the lock jig driving portion to make the lock jig sandwich the pulled-out part, insert the lock jig between the clip and the inner surface, and open the tip end portions (51a, 52a) of the lock jig against biasing force of the clip to open the clip. a reel driving portion configured to rotate the reel; a wire feeding portion configured to supply the wire to the reel while applying tension to the pulled-out part; a lock jig including a pair of tip end portions (51a, 52a) configured to approach each other or separate from each other; a lock jig driving portion configured to make the lock jig move and make the pair of tip end portions (51a, 52a) of the lock jig approach each other or separate from each other; and a control portion, wherein: the control portion is configured to execute a step of controlling the reel driving portion and the wire feeding portion to wind the wire onto the winding drum, and a step (S12, S13, S16) of controlling the lock jig driving portion to make the lock jig sandwich the pulled-out part, insert the lock jig between the clip and the inner surface, and open the tip end portions (51a, 52a) of the lock jig against biasing force of the clip to open the clip. a step of controlling the reel driving portion and the wire feeding portion to wind the wire onto the winding drum, and a step (S12, S13, S16) of controlling the lock jig driving portion to make the lock jig sandwich the pulled-out part, insert the lock jig between the clip and the inner surface, and open the tip end portions (51a, 52a) of the lock jig against biasing force of the clip to open the clip.
