Zusammenfassung:	A method for fitting a protection tube (5) to a gas sensor (1) includes: a step for engaging tube-end opening jigs (113) which have been inserted into the inside of a protection tube (5) through its one end portion (5e), with this end portion, for maintaining this end portion at an opened state, a step for bringing tube-end holding jigs (121) into contact with this engagement portion from outside for holding the tube through pinching between these jigs, and a step for inserting the sensor into the inside of the tube being held through pinching, wherein the insertion of the sensor into the inside of the tube is continued even after an end portion of the sensor comes into contact with the inner surface of the tube, while the engagement of the tube with the tube-end opening jigs is gradually released, thereby fitting the tube to the sensor.
