PROBLEM TO BE SOLVED: To provide a lash adjuster installation structure capable of forming a passage for releasing air at the time of insertion of a lash adjuster into a lash adjuster insertion hole without producing burr. SOLUTION: A sleeve 9 is interposed between the lash adjuster installation hole 34 and the lash adjuster, and an air releasing passage 9A is formed between an outer circumference surface of the sleeve 9 and an inner circumference surface of the lash adjuster installation hole 34 by forming an air releasing groove 92 on the outer circumference surface of the sleeve 9. Consequently, air in a space formed by an inside of the sleeve 9 and a bottom surface of the lash adjuster 82 is released from an upper surface of a cylinder head 3 through the air releasing passage 9A at the time of insertion work of the lash adjuster 82.
