PURPOSE: To enable continuous traveling of a capsule at a joint of a pipeline by arranging electromagnets at the outside of the side face section of a pipe branch and the outside of the side face section of main line and then controlling the electromagnets.
CONSTITUTION: A coil 13 of an electromagnet for main line is fixed to the outside of the side face section 11a of a main line at a branch section 10. A coil 14 of an electromagnet for a branch line is fixed to the outside of the side face section 10a at the branch section 10. Furthermore, coils 5 of electromagnets are fixed to the outside of the upper and lower faces of branch section 10 and the main line 11. Electromagnets 14 for the branch line, electromagnets for the main line and the electromagnets 5 are arranged at same interval.
