Abstract: A valve drive apparatus having a shim which is prevented from interfering with a cylinder head without decreasing abrasion resistance between the shim and a lifter contacting the shim. A three-dimensional cam includes a cam portion having a slanting cam surface inclined with respect to a rotational axis of the cam. The cam is movable along the rotational axis. The lifter transmits a force generated by a camming action of the cam to the valve. The lifter has a first surface contacting the valve and a second surface substantially opposite to the first surface. A shim is interposed between the cam and the lifter. The shim has a first surface contacting the cam and a second surface opposite to the first surface. The second surface of the shim has a convex spherical shape, and the second surface of the lifter has a concave spherical shape so as to receive the second surface of the shim.
