To provide a treatment device whereby an effective treatment can be performed in relation with respiration. A treatment device 100 is provided with a treatment part 17 performing a treatment by repeating a large load operation of applying a relatively large load to a subject to be treated and a small load operation of applying a relatively small or no load to the subject, and a respiration guiding part 82 guiding the subject to breath in synchronization with preset standard respiration, wherein the treatment part 17 is configured so as to perform the large load operation at exhalation in the standard respiration and perform the small load operation at inhalation in the standard respiration.本發明提供一種可配合呼吸而進行有效施療之施療裝置。施療裝置100具備施療部17及呼吸誘導部82，該施療部17係藉由反復進行向被施療者施加相對較大的負載之強負載動作、及向被施療者施加相對較小的負載或不對被施療者施加負載之弱負載動作而施療，該呼吸誘導部82係對被施療者進行誘導，以使其與預先設定之標準呼吸同步地呼吸；施療部17係以如下方式構成：於標準呼吸之呼氣時進行強負載動作，且於標準呼吸之吸氣時進行弱負載動作。
