    摘要： A rocker arm unit comprises a lash adjuster having a plunger extending axially and a cylindrical body which houses the plunger so that the plunger is slidable; a rocker arm supported by an upper end of the plunger and swung with the supported position serving as a pivot; and a clip which is fixed to the body so as to extend from the fixed position to engage the rocker arm, thereby restricting drop of the rocker arm out of the lash adjuster.

    摘要： A rocker arm (10) for an internal combustion engine includes a roller (11) brought into contact with a cam (90) thereby to be rotated, an arm body (12) having a storage portion (17) in which the roller (11) is stored, the arm body (12) being swung by rotation of the cam (90), thereby opening and closing a valve (83). The storage portion (17) has an opening edge located on an upper surface of the arm body (12) and opposed to a circumferential surface of the roller (11), and the opening edge includes a part receiving lubricant oil flowing along the upper surface of the arm body (12), the part being formed with a receiving opening edge (33) jutting out so that both widthwise ends thereof are located away from the circumferential surface of the roller (11) and so that a widthwise central portion thereof comes close to the circumferential surface of the roller (11).

    摘要： A rocker arm (6) that is rockably attached to a cylinder head (1) actuates a valve (4) by means of a guide groove (73b) that is formed at an end thereof engaging with an upper end of a valve stem (41), and a roller (8) that is mounted in a roller housing portion (72) of the arm main unit (7) contacting against a cam (31) and rocking. The guide groove (73b) is formed by press working ends of the arm main unit (7) in the thickness direction of the plate material to form a pair of walls (73d), and thereafter applying sandwiching pressure in the lateral direction to the walls (73d) to increase the height thereof.

    摘要： A variable valve mechanism of an internal combustion engine includes an input arm, an output arm, a lock pin, a drive device and a return spring of the lock pin, and a lost motion spring of the input arm. The input arm has in its rear end portion a pushback surface and a stopped surface. The lock pin has in its distal end portion a pushed-back surface and a stopping surface. The drive device includes a driving source and a mover that moves to push the lock pin when driven by the driving source. A driving force of the driving source is set so as to be smaller than a force with which the pushback surface pushes back the pushed-back surface as the lost motion spring causes the input arm to freely swing upward and be larger than load with which the return spring displaces the lock pin.
