Amendment September 6, 1983 The brief description of the drawing is amended as follows. After the 5th line of page 12 of the specification, ``...'', a new line is added to ``Figure 8 shows a case in which a rocker arm having a conventional flat cam slipper comes into sliding contact with a cam while being inclined with respect to the camshaft.'' 9 is a diagram showing the stress distribution of the cam slipper along the axial direction of the rocker arm shown in FIG. 8 in the attached state." On page 13 of the specification, line 7, after “42...return spring”, a new line is added to read “51...rocker arm, 51a...axis line, 52...camshaft, 52
a...axis line, 53...cam slipper, 54...cam surface, 55...cam" are added.
