Abstract:
To provide a bearing member for a valve gear capable of reducing friction. A bearing member (34) for a valve gear (1) includes a cam shaft (20). The cam shaft (20) has: 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) includes: a cam cap (38) supporting the journal part (36) from above, surrounding it; a bearing base part (40) supporting the journal part (36) from below; and a stepped part (46a) provided on an inner peripheral surface of the cam cap (38) facing the journal part (36), overhanging on an inner peripheral side of the inner peripheral surface. An upstream-side end portion (46c) of the stepped part (46a) is positioned more on a downstream side than an upstream-side abutting surface (38a) of the cam cap (38), whereas a downstream-side end portion (46d) of the stepped part (46a) is positioned more on an upstream side than a downstream-side abutting surface (38b) of the cam cap (38).
