<p>PROBLEM TO BE SOLVED: To provide a bearing member for a valve gear, for preventing contact between the inner peripheral face of a cam cap and a journal, at a portion of the cam cap where a contact pressure is most applied.SOLUTION: A bearing member 34 for a valve gear 1 includes a cam shaft 20 having a cam 30 for opening/closing at least one of an intake valve and an exhaust valve, and a plurality of journal parts 36. The bearing member 34 has a cam cap 38 downward supporting the journal parts 36 of the cam shaft 20 so as to encircle them, and a bearing base part 40 upward supporting them. The inner peripheral face of the cam cap 38 opposed to the journal parts 36 is coated with a resin coating film 46a in such a manner that peripheral ends 46b, 46b of the resin coating film 46a are each thinner than a peripheral center 46c.</p> |
