PROBLEM TO BE SOLVED: To provide a joint cover apparatus which can absorb longitudinal and transverse jolts that rock right and left skeletons differently from each other, and covers a joint portion without forming a gap. SOLUTION: The joint cover apparatus is formed of: a fixed side support cover rotatably mounted on one of the skeletons via a hinge member; a fixed side joint plate rotatably mounted on the other skeleton via a hinge member; at least two expansion links each having one end thereof pivoted on a portion of the fixed side joint plate, at a location on a free-end side and close to a rear end, and the other end pivoted on the fixed side support bar, and each having a plurality of pivoting portions always set at equal intervals, even in an expanded/contracted state; a plurality of movable support bars pivotally mounted on the pivoting portions of the at least two or more expansion links, so as to be in parallel with each other; and a plurality of joint cover members each having a crank-shaped rear end mounted on the plurality of movable support bars in a manner always being energized toward the movable support bars, and a front end slidably superposed on the fixed side joint plate or the joint cover member adjacent thereto and supported by the same.
