This article constitutes an approach to itinerants' social space through their unceasing migrations and their periodical links to the grounds of the fun fair. Lille fun fair-ground has been used as a basis to our study because of its local impact and the large amount of itinerants who are there, related to the annual jumblesale. The fun fair-ground integrates four levels of spaces and rhythms of migration each of which permanently associates the itinerants' trades and their homes. Cohabitation in Lille simultaneously shows the solidarity of the group and the tentative openings towards the town. But the fluidity and the recurrent breakings of social relationship encourage the manifestations of individualism whereas the local regulations, because they made the fun fair official, circumscribe it to the suburban areas.
