Abstract
Disclosed is a slit lamp microscope capable of forming a slit superior in terms of parallelism. The slit lamp microscope includes casings (L andR) to the bottoms surfaces of which slit blades (L) and (R) are fixed and which are connected together so as to be rotatable around shaft members (), and an inter-casing distance varying member () adapted to change the distance between the casings (L andR) in correspondence with vertical movement of an ascent/descent shaft (). Coil-like portions of torsion springs () are wound around the shaft members () to which the casings (L andR) are connected. The torsion springs () urge the casings (L andR) so as to bring the slit blades (L andR) close to each other. Further, the casings (L andR) are equipped with U-shaped springs () urging protrusions (L' andR′) thereof so as to press them against the shaft members ().
