1. An X-ray diagnostic apparatus comprising:
an arm
that has a shape of a circular arc,
that, at one end thereof, supports an X-ray tube which emits X-rays onto a subject, and
that, at another end thereof, supports an X-ray detector which detects X-rays that have passed through the subject;
a first holder that grasps the arm in a slidable manner in a circular arc direction;
a second holder that supports the first holder in a slidable manner in the circular arc direction;
a driver
that is disposed in the second holder,
that moves the first holder, and
that, at a same time, relatively moves the arm with respect to the first holder; and
a third holder that is orthogonal to a rotation axis involved in movement of the arm in the circular arc direction and that holds the second holder in a rotatable manner with a rotation axis substantially orthogonal to a vertical direction, wherein
the first holder slides in the same circular arc direction as the arm up to a position of being pushed out from the second holder.
