PROBLEM TO BE SOLVED: To provide an X-ray diagnostic apparatus preventing a display apparatus from being moved by unforeseen external force to improve usability when making positional adjustment of the display apparatus.SOLUTION: An X-ray diagnostic apparatus is structured as follows: a display apparatus carriage 9 is provided with a lock mechanism 21 which locks the up-and-down movement of a support 10 while allowing turn thereof; the lock mechanism 21 includes a pair of rubber locking rollers 22, an arm 23, a toggle mechanism 24, an operation lever 25 and a base part 26; the locking rollers 22 are displaceable between the locking positions where the rollers are pushed against the side surface of the support 10 and releasing positions where the rollers separate from the support 10; and the locking rollers 22 which rotate due to the turn of the support 10 to allow the turn of the support 10, and also inhibit the up-and-down movement of the support 10 due to frictional force against the support 10 when the rollers are located at the locking positions. |
