Abstract: A lifter includes a roller caused to abut against a cam thereby to be pressed and a lifter body rotatably supporting the roller and housed in a guide hole of a lifter guide so as to be reciprocable in the guide hole. The lifter body includes a cylindrical part and a rotation stopper. The cylindrical part has an outer periphery formed into a cylindrical shape such that the outer periphery is slidable on an inner periphery of the guide hole. The cylindrical part has one of two axial ends, the one end being formed with a skirt covering the roller. The rotation stopper is formed to protrude outward from the other axial end of the cylindrical part, the other axial end being located opposite a side where the skirt is located. The rotation stopper prevents the lifter body from being rotated about an axis thereof relative to the lifter guide.

Abstract: Providing a rocker arm which can ensure the durability while reducing the inertial mass. The rocker arm (10) includes a valve abutment part (15) pressing a valve (80). The valve abutment part (15) includes a receiving wall (14) abutting against an end surface of a stem end (81A) of the valve (80) in a pressing state and a pair of sidewalls (13) protruding from both side ends (14A) of the receiving wall (14) so as to be opposed to each other and disposed along and in proximity to a side peripheral surface of the stem end (81A) of the valve (80). At least protruding distal ends of the sidewalls (13) each have a smaller thickness than adjacent portions and serve as a thinner portion (23).

Abstract: A lifter rotation preventing structure includes a lifter body, a retainer and a biasing member. The lifter body is inserted into a sliding hole of a housing and reciprocated according to rotation of a cam. The lifter body has a peripheral wall slidable in a sliding hole and a partition wall partitioning an inside of the peripheral wall into a first space where the cam is located and a second space located opposite the first space. The retainer has a retainer body connected to an engaging member and a rotation preventing protrusion protruding from an outer periphery of the retainer body and fittingly extending through the peripheral wall. The rotation preventing protrusion has a distal end moved into a rotation preventing groove to prevent the lifter body from rotation. The biasing member interposed between the retainer body and the housing to bias the lifter body to the cam side.

Abstract: A lifter structure includes a cylindrical member configured to be reciprocally slid in a guide hole of a lifter guide according to rotation of a cam and having an engagement groove and a rotation-preventing member which is separate from the cylindrical member and is disposed so as to face an interior of the guide hole. The rotation-preventing member is inserted into the engagement groove to abut against a groove edge of the engagement groove in a rotation direction of the cylindrical member, thereby preventing the cylindrical member from rotation in the guide hole.
