1. A wire rod disposing device, comprising:
a wire rod delivering mechanism configured to deliver a wire rod from a nozzle at a predetermined speed;
a member support part configured to support a disposition target member such that the wire rod is routed after the wire rod is delivered from the nozzle and curved; and
a tension application mechanism configured to apply tension to the wire rod, the wire rod being routed to the disposition target member by being delivered from the nozzle, wherein
the tension application mechanism has:
a wire rod guide in contact with a curvature-inner side of the wire rod that has been delivered from the nozzle and curved; and
an elastic member configured to bias the wire rod guide such that the wire rod guide is moved towards a curvature-outer side of the wire rod; and
a tension bar pivotable about a pinned support,
the wire rod guide is attached to the tension bar, and
the elastic member is configured to bias and rotate the tension bar such that the wire rod guide is to be moved towards the curvature-outer side of the wire rod.
