Abstract: A radiation detector includes an image generator and a case. The image generator generates a radiograph according to received radiation. The case stores the image generator and includes a first component and a second component screwed to the first component. The second component is movable with respect to the first component in a direction along a seat surface of a screw by a screw hole of the second component being formed such that a diameter is larger than a diameter of a shaft of the screw but smaller than a diameter of a head of the screw. A loosening torque that acts, in a direction to loosen the screw, on the screw when the seat surface receives a frictional force from the second component is smaller than a loosening start torque that is the loosening torque of when the screw starts to loosen.
