The X-ray fluoroscopic apparatus (100) includes guide surfaces (31a, 32a, 231a, 232a) that contact a guide member (40) that guides the rotation of the top plate (1), and is provided below the top plate. And at least one holding member (20, 220) and a plurality of anti-sway members (50, 253, 254) that hold the holding member in the longitudinal direction of the top plate and suppress horizontal shake operations other than rotation of the top plate And comprising.このＸ線透視撮影装置（１００）は、天板（１）の回動をガイドするガイド部材（４０）と接するガイド面（３１ａ、３２ａ、２３１ａ、２３２ａ）を含み、天板の下方に設けられた少なくとも１つの保持部材（２０、２２０）と、天板長手方向に保持部材を挟み込んで天板の回動以外の水平方向の振れ動作を抑制する複数の振れ止め部材（５０、２５３、２５４）と、を備える。
