摘要： PROBLEM TO BE SOLVED: To reduce a time and labor in the assembling of a cam shaft and regulate the increase of friction between an insertion hole and a shaft. SOLUTION: In this cam shaft supporting structure, in a cam shaft receiving space 6 defined between a cylinder head 1 and a head cover 2, there are provided the cam shaft 21 comprised of a plurality of cam pieces 21A and the shaft 21B and a plurality of bearing pieces 3 each having the insertion holes 20 for rotatably supporting the shaft 21B and fixed to the cylinder head 1. The inner peripheral surface of the insertion hole 20 continues without discontinuity along the entire periphery, and the entire periphery serves as a sliding surface coming into slide-contact with the outer peripheral surface of the shaft 21B. This dispenses with the detaching work of a cam cap and the circularity of the insertion hole is kept constant. The time and labor in the assembling of the cam shaft 21 is therefore reduced and the increase of friction between the inner peripheral surface of the insertion hole 20 and the outer peripheral surface of the shaft 21B is regulated.
