PROBLEM TO BE SOLVED: To provide a small-sized and light-weighted mono tank capable of reducing the size and the weight of an X-ray diagnostic apparatus.SOLUTION: The mono tank includes an anode fixing part 205 integrated with an insulation cylinder, which fixes an X-ray tube 101 to a tubular cylinder 104 for storing the X-ray tube, and insulate the X-ray tube 101 from a starter coil 102. The anode fixing part 205 integrated with an insulation cylinder has a connection part 206 as a position fixing the tubular cylinder 204, which is disposed at a position closer to the focus of the X-ray tube than the starter coil 102.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2016,JPO&INPIT【課題】モノタンクの小型・軽量化を図ることにより、X線診断装置の小型・軽量化を図る。【解決手段】X線管101とX線管を内蔵するための管球筒104とを固定し、X線管101とスターター・コイル102とを絶縁する絶縁筒一体型アノード固定部205を備え、この絶縁筒一体型アノード固定部205を管球筒204に固定する位置である接続部分206を、スターター・コイル102の位置よりX線管の焦点側にした。【選択図】図1
