Abstract
A motion converting section () and a translation bar () of a feedback mechanism () are provided between a lateral side of a swash plate () and a control sleeve () of a regulator (). When the swash plate () is in a neutral position, the motion converting section () is located in an initial position (F—F) at one end of axial direction along an axis line (O—O) passing through a tilting center (C) of tilting motions, and, when the swash plate () is driven to tilt in a forward or reverse direction, displaced to the other end of axial direction along the axis line (O—O) to convert a tilting motion of the swash plate () into an axial displacement. Through the translation bar (), the axial displacement is transmitted to the control sleeve () of the regulator () as an axial displacement.
