Abstract

A valve driving apparatus using a direct driving type valve lifter is disposed between a cam (803) and a valve (105,117,118,217,317,417,517,617,717,807), said apparatus comprising: a guide hole (123,213,313,413,513,613,713,806) and a direct driving type valve lifter (101,214,314,414,514,614,714,811) including a tappet portion (103,216,316,416,516,616,716,813), and a guide portion (104,215,315,415,515,615,715,812) having one end portion coupled to said tappet portion and housed within said guide hole so as to slide freely therein to the axial direction of said poppet valve in an interlocked manner; wherein a diameter (r) of said guide portion is formed to be smaller than a diameter (R) of said tappet portion; characterized in that said valve lifter (101,214,314,414,514,614,714,811) is inclined in a direction perpendicular to a rotational axis of the cam relative to the head bolt (109) for securing the cylinder head; and said valve lifter is arranged so as to be adjacent to the head bolt in a planar view.
