<p>PROBLEM TO BE SOLVED: To provide a support mechanism of a locker arm which is easy in assembling to a cylinder head.SOLUTION: A support mechanism 50 comprises: a compression] coil spring 80; a seat face 71; a pedestal 70 having a peripheral side face 72 extending to a side opposite to the spring 80 from a peripheral edge of the seat face 71; a support part 61 for supporting an oscillation pivot part 42 of a locker arm 40; a ceiling face 62 abutting on another end face 80b so as to sandwich the spring 80 between the seat face 71 and itself; and a support moving body 60 having a cylindrical outer wall part 63 which surrounds the spring 80, and is movable in an elongation/contraction direction of the spring 80 along the peripheral side face 72. The support moving body 60 has an annular groove part 64 at an internal peripheral face 63 of the outer wall part 63. The pedestal 70 has an inner wall part 73 erected at the peripheral edge of the seat face 71, and a penetration hole 75 which is formed at the inner wall part 73 and overlapped with the groove part 64. The spring 80 has a lock end part 81a which is formed of an end part of a wire rod constituting the spring 80, protrudes to the outside rather than a coil-shaped external peripheral edge of the other end face 80b, is inserted into the groove part 64 through the penetration hole 75, and lockable to the outer wall part 63.</p> |
