1. A marking positioning device for an elevator, comprising:
a body that flies inside a hoistway of an elevator;
a detector at the body and configured to detect a position of the body inside the hoistway;
a marker at the body and to perform marking;
a control circuitry at the body and configured to control flight of the body on a basis of the position detected by the detector so that a position of marking by the marker is located at a designated position set in a three-dimensional shape inside the hoistway;
a support at a hall of the elevator so as not to drop inside the hoistway;
a projection connected to the support and projecting to inside of the hoistway; and
a connector having a string shape and connecting the projection with the body.
