Abstract
A valve gear includes a valve main body having a valve chamber in an inner portion, a valve body having a flow channel space in an inner portion and changing a flow rate for fluid by being rotated and driven within the valve chamber, a first flow channel hole formed in the valve main body and communicated with the flow channel space to allow the fluid to pass through, a second flow channel hole formed in the valve main body changing a communicated state with the flow channel space by a rotational displacement position of the valve body and allowing the fluid to pass through when being communicated with the flow channel space, and a transmission mechanism including a valve body drive shaft transmitting a drive force for rotating the valve body to the valve body. Rotation axes of the valve body and the valve body drive shaft are orthogonal.
