Abstract: An in-tube transit object that is inserted in a tube includes: a coil section formed by winding a wire; and a fiber section attached to an end on one side and an end on the other side in a winding-axis direction of the coil section. The coil section is formed with a large diameter section, through which fiber of the fiber section is inserted, at the end on the one side and the end on the other side, and is inserted in an extending state in the winding-axis direction when the in-tube transit object is inserted into the tube. The fiber section is configured to expand when seen in the winding-axis direction in the case where the in-tube transit object is inserted in the tube and then discharged from the tube, which brings the coil section into a compressed state in the winding-axis direction.
