Description

【図面の簡単な説明】[Brief explanation of the drawing]

第１図は従来用いられている動圧流体軸受スピンドルの
断面図、第２図はこの考案による第１図、　と同一の型
式のスピンドルの実施例の要部の断面図である。 図中符号１は軸、２はスリーブ、３はスラスト受部材、
４は制限部材、５は周みぞ、６および７は動圧発生みぞ
、８はねじ孔である。FIG. 1 is a sectional view of a conventionally used hydrodynamic bearing spindle, and FIG. 2 is a sectional view of the main parts of an embodiment of the same type of spindle as in FIG. 1 according to this invention. In the figure, 1 is a shaft, 2 is a sleeve, 3 is a thrust receiving member,
4 is a limiting member, 5 is a circumferential groove, 6 and 7 are dynamic pressure generating grooves, and 8 is a screw hole.
