VARIABLE VALVE DEVICE

摘要

A variable valve device in which friction during transmission of drive force can be suppressed and which can achieve high durability with a compact construction. The diameter of a first roller (170) in contact with a drive cam surface (124) of a camshaft (120) is made greater than the diameter of a second roller (172) in contact with a slide surface (156) of a rock member (150). The first roller (170) and the second roller (172) are connected by a connection shaft (174) so as to be rotatable independently of each other. Further, the slide surface (156) is formed to curve to the drive cam surface (124) side.
