X-RAY TOMOGRAPHIC DEVICE

PROBLEM TO BE SOLVED: To provide an X-ray tomographic device supporting an X-ray bulb device and an X-ray detecting device with an inboard structure, preventing their flapping, capable of suppressing the occurrence of vibration even at high- speed rotation, and capable of expanding an X-ray radiation range. SOLUTION: An X-ray radiation device section 50 in this X-ray tomographic device is arranged with parallel annular frames 1130, 1140 so that a base end section 1010 is coupled and fixed to the circular through hole 511 of a main body frame 510 arranged nearly vertically and the X-ray radiation device section 50 can be rotated via bearing devices 1110, 1120 at both end sections on the outer periphery around a cylinder shaft 10 fitted nearly vertically to the main body frame 510. An X-ray bulb device 6 and an X-ray detecting device 7 are rotatably mounted on bases 1150, 1151 suspended on the annular frames 1130, 1140 respectively, and the tip section 1020 of the cylinder shaft 10 is supported by a support member 13.
