Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a cryogenic refrigeration apparatus having improved refrigeration efficiency.SOLUTION: The cryogenic refrigeration apparatus includes a displacer caused to reciprocate in a cylinder by the Scotch yoke mechanism 32 including a Scotch yoke 36 (slide groove 38) to which a bearing 35 is movably engaged with, and generates cold by expanding a refrigerant gas inside an expansion space formed in the cylinder by the reciprocation of the displacer. A concave part 45 is provided at a position corresponding to a top dead center of the displacer of the Scotch yoke 36.
