造。 A roller lifter having a rotatable roller that comes into contact with a cam of a camshaft is slidably held in a cylinder head, and rotation of the roller lifter about its axis is regulated by a rotation prevention guide fixed to the cylinder head side. In the anti-rotation guide structure for a roller lifter, a cylindrical anti-rotation guide capable of slidingly contacting the anti-rotation portion is disposed on the outer periphery of the anti-rotation portion of the roller lifter, and the anti-rotation guide is arranged in the direction of movement of the roller lifter. A rotation prevention guide structure for a roller lifter, characterized in that it is fixed to a cylinder head side via a support member having high rigidity in the direction perpendicular to the cylinder head and low rigidity in the torsional direction.
