The security curtain includes an elongated strip of flexible material having a width generally equal to the distance between the spaced vehicle walls and with an end edge thereof attached to a rotatable support roller so that the curtain may be wrapped around the roller when in a retracted or stored operative position. The ends of the support roller are attached to the vehicle sidewall and supported thereby by means of cap members on the ends of the roller support in a manner permitting relative rotation therebetween.
