ABSTRACT:
A support device of the present invention includes an expansible means attached to at least one of plural support systems for supporting an object. Even when the object has dimensional errors caused in its making process, therefore, the interval between the support systems which contact the object to be supported can be self- and micro-adjusted. This enables objects, different in shape, to be correctly positioned and supported.
