Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a vertical shaft pump capable of suppressing local temperature rise of a rotational shaft in non-lubrication slide, to thereby prevent thermal bending of the rotational shaft.SOLUTION: A rotary machine includes: a rotational shaft 2; a sleeve 8 provided on an outer periphery of the rotational shaft 2; and a bearing 10 supporting the rotational shaft 2 arranged so as to have an interval between itself and an outer peripheral surface 8a of the sleeve 8. Between the rotational shaft 2 and the sleeve 8, provided is a high heat conductive member 11 having higher heat conductivity than the rotational shaft 2.SELECTED DRAWING: Figure 2 【課題】本発明の目的は、無潤滑摺動時における回転軸の局所的な温度上昇を抑制し、回転軸の熱曲がりを防止することができる立軸ポンプを提供することにある。【解決手段】回転軸２と、回転軸２の外周に設けられたスリーブ８と、スリーブ８の外周面８ａとの間に間隔を隔てて配置され回転軸２を支持する軸受１０と、を有した回転機械であって、回転軸２とスリーブ８との間に回転軸２よりも高い熱伝導率を有する高熱伝導性部材１１を設ける。【選択図】図２
