A yarn twisting device is simple in structure but capable of easily producing twisted yarn made of a plurality of yarn pieces twisted together. The yarn twisting device includes: a case; an operation wheel rotatably supported by the case so that an outer circumference of the operation wheel is partly exposed outside the case; and a plurality of yarn holding shafts supported by the case so as to protrude from one surface of the case and that axially rotate with the rotation of the operation wheel in the same direction.
