PROBLEM TO BE SOLVED: To make it possible to easily fix the simply configured main body of an ultrasound diagnostic apparatus in an installation position when in use and to suitably perform ultrasound diagnosis even if the outer peripheral portion of the ultrasound diagnostic apparatus is rotatable.SOLUTION: An ultrasound diagnostic apparatus comprises: the main body 110 of the apparatus to which a display unit 112 for displaying ultrasound images is attached and an outer peripheral portion 140 of the apparatus which is disposed in an outer periphery of the main body 110 and carries the main body 110 in a vertically liftable and relatively horizontally rotatable manner, and to undersurface of which casters 160 for rotational movement on a floor F are attached. A bottom surface 122 of the main body 110 is displaced downward when moved downward relative to the outer peripheral portion 140, and abuts the floor F to restrict the casters 160 rotationally moving on the floor to thereby fix the main body 110.SELECTED DRAWING: Figure 3COPYRIGHT: (C)2017,JPO&INPIT【課題】使用時において、超音波診断装置本体を簡易な構成で容易に設置位置に固定しつつ、超音波診断装置外周部が回動可能であっても安全に好適に超音波診断を行う。【解決手段】超音波画像を表示するディスプレイ112が取り付けられる超音波診断装置本体110と、超音波診断装置本体110の外周に配置され、超音波診断装置本体110を上下昇降自在に且つ水平方向に相対的に回動可能に支持するとともに、下面に床Fを転動する移動用キャスター160が取り付けられる装置外周部140と、を有し、超音波診断装置本体110の底面122は、装置外周部140に対して下方に移動した際に下方に変位し、床Fに当接して床上での移動用キャスター160の転動を規制して超音波診断装置本体110を固定する。【選択図】図3
