Claim:
1. Particle radiation therapy equipment comprising: an irradiation device that irradiates a patient with accelerated particles; a particle accelerator that generates the accelerated particles; a guide line that guides the accelerated particle generated by the particle accelerator to the irradiation device; a building that has a multi-story structure, wherein the irradiation device includes a rotating unit that is rotatable about a rotation axis, an irradiation unit that is disposed on the rotating unit and irradiates with the accelerated particles, and an introduction line that introduces the accelerated particles guided by the guide line to the irradiation unit, the introduction line being connected to the guide line and the irradiation unit, wherein the introduction line includes a radial introduction line that is curved at an angle of 90° with respect to the rotation axis from a start end portion thereof communicating with the guide line on the rotation axis and extends in a radial direction of the rotating unit, and a circumferential introduction line that includes one end connected to a terminal end portion of the radial introduction line and an other end connected to the irradiation unit, the circumferential introduction line being curved and extending in a circumferential direction of the rotating unit between the one end and the other end, and wherein the irradiation device is installed on at least one of upper and lower floors of a floor on which the particle accelerator is installed, in the building.
