A rail type fixing apparatus for installing panels includes a rail120having an elongate shape and a plurality of attachment panels30inserted into the rail so that they can be moved. The rail120has a lower surface120a, a top surface120bon which the panels are placed, and a guide groove121spaced a little apart from the inside bottom in the longitudinal direction. The attachment panel30is provided with a guide panel31extended from the bottom edges thereof so that it is guided by the guide groove121to move in the longitudinal direction of the rail120, and a hook projection132formed protruding and perpendicularly with respect to the longitudinal direction from the top surface, the hook projection hooked with and maintained to a first hook groove4of the panel1and a second hook groove7of the other panel1. An attachment panel30and an adjacent attachment panel30are applied of the tension restoring force by the elastic member so that the both hook projections132close to each other.
