Abstract
To provide a steering device capable of highly precisely controlling turning angles of steered wheels without changing a layout of members. Provided is a steering device (10A) including: a center arm (26) having one end portion configured to swing in a right-and-left direction with respect to a vehicle body (BD) in synchronism with rotation of a steering shaft (22); a rod member (40A), which is coupled to the one end of the center arm (26), and is configured to move in the right-and-left direction, to thereby change turning angles of steered wheels (WR and WL); and a rod-member drive device (50) configured to linearly move the rod member (40A) in the right-and-left direction through use of a driving force source. The rod member (40A) is supported such that movement of the rod member (40A) in the right-and-left direction of the vehicle body (BD) is allowed, but movement of the rod member (40A) in a front-and-rear direction and an up-and-down direction of the vehicle body (BD) is restricted. The one end portion the center arm (26) and the rod member (40A) are coupled so as to be relatively movable in the front-and-rear direction of the vehicle body (BD).
