A valve control apparatus includes a drive shaft; a control shaft including a control shaft main body configured to be rotationally controlled according to a state of engine, and a control eccentric shaft located eccentrically relative to a rotation center of the control shaft main body; a rocker arm swingably supported by the control eccentric shaft and configured to convert a rotational motion of the drive shaft to a swinging motion; and a swing cam configured to open/close an engine valve according to the swinging motion of rocker arm. Both ends of the control eccentric shaft are formed with fixing holes extending in a radial direction of the control eccentric shaft. The control shaft main body is formed with insertion holes passing through the control shaft main body in a radial direction of the control shaft main body. The insertion holes respectively face the fixing holes. The control eccentric shaft is fixed to the control shaft main body by bolts. The bolts pass respectively through the pair of insertion holes and are screwed respectively into the fixing holes.
