1. An X-ray diagnostic apparatus, comprising:
an X-ray generator configured to generate X-rays;
a grid configured to remove scattered rays from X-rays emitted from the X-ray generator;
an X-ray detector configured to detect X-rays that have passed through the grid;
a first support configured to support the grid by pressing the grid; and
a second support configured to support the grid by pressing the grid, wherein
a number of directions in which the first support restricts movement of the grid is different from a number of directions in which the second support restricts movement of the grid,
the first support and the second support are arranged on at least one of two opposite sides of the grid,
directions in which movement of the grid is restricted include a first direction perpendicular to the grid, a second direction that is a direction in which the grid is attached and detached, and a third direction orthogonal to the first direction and the second direction, and
the apparatus further includes a first rail and a second rail provided in the grid to be opposed to each other, and a first guide and a second guide provided in the X-ray detector to be opposed to each other and to be insertable into the first rail and the second rail, respectively, wherein the second rail has a concave portion, and the second support fits into the concave portion to restrict movement of the grid.
