PROBLEM TO BE SOLVED: To provide a sterling refrigerator capable of sufficiently supplying a lubricant at the timing when the friction of a sliding part of a connecting rod and a crank part in a crank chamber becomes maximum, improving the reliability and the life of the sterling refrigerator, and reducing the mechanical loss by friction. SOLUTION: A lubricant hole 54 formed on the crank part 13 is formed at a large-diameter side of the crank part 13 to be directed to a bottom part 59 of a large end part 9a of the con-rod 9, when the con-rod 9 exists at a lowest point.
