<p>A rocker cam (40) is comprised of a first split body (41) and a second split body (45), which are joined with a joint split face that contains an axial line of a cam shaft (3). The first split body (41) has a first pin support portion (42) that supports one end portion of the connection pin (31), and the second split body (45) has a second pin support portion (46) that is located so as to face the first pin support portion (42) and supports the other end portion of the connection pin (31). The connection pin (31) is supported at the first and second pin support portions (42,46) at its both end portions. Accordingly, a separation force that acts on the first and second split bodies of the rocker cam during its repeated rocking movement can be reduced without improperly increasing its rigidity.</p> |
