Abstract:
In the present invention, control shafts (11A, 11B) having bodies (16A, 16B) and control arm parts (17A, 17B) extending from the bodies (16A, 16B) toward the outer side in the radial direction are rotatably provided on the outer peripheral surface of a drive camshaft (2). A cam follower (13) is oscillatably mounted to the control arm parts (17A, 17B) via a support shaft (25). Oscillating arm parts (35A, 35B) extending toward the position opposite to a drive cam (3) across a cam follower roller (27) are provided on oscillating cams (14A, 14B). A central shaft (26) of the cam follower roller (27) is connected to the oscillating arm parts (35A, 35B) by link arms (29A, 29B) of which both longitudinal ends are rotatably connected to the central shaft (26) of the cam follower roller (27) and the oscillating arm parts (35A, 35B).
