Abstract
Various micro-electric vehicles (EV) have been made by a lot of manufacturers in the world since approximately two decades before. Few numbers of such small cars, however, have come into use in Japan. This is mainly because the proper utilities have not been considered sufficiently while the micro-EV's would not be substitutes for the ordinary cars including "Kei (Light)" class cars in Japan. The micro-EV's can be very useful transfer method when their characteristics or their essentials are considered enough. Several kinds of prototypes of micro-EV's made by the authors are shown in this paper and the prototypes have various utilities as maintenance service in the woods in the suburban areas, picking-up a member of a family to hospital and mothers' transfer with children more than one, etc. The benefit of such prototypes is verified at the same time that the functions of them are not provided for the ordinary cars.
