摘要： In a motor having a spindle (5) on which an inner race (8) of a ball bearing is mounted, an outer peripheral surface of an end of the spindle (5) has a knurled portion (16) on which is mounted the inner race (8) which is fixed to the spindle (5) through an adhesive (18) filled in a clearance between an inner surface of the inner race (8) and the knurled portion (16). An annular groove (19), formed in the spindle (5) in an area adjacent to the knurled portion (16), is also filled with the adhesive (18) to further fix the inner race (8) to the spindle (5), which improves the adhesive bond between the inner race (8) and the spindle (5). Even when the ball bearing is a miniature one having a thin-wall inner race (8), there is no fear of deformation of the inner race (8) when the adhesive (18) is cured, which improves the rotational accuracy of the rotor.
摘要翻译：在具有安装有滚珠轴承的内圈（8）的主轴（5）的电动机中，主轴（5）的端部的外周面具有滚花部（16），在其上安装有内圈（8），其通过填充在内座圈（8）的内表面和滚花部分（16）之间的间隙中的粘合剂（18）固定到主轴（5）。在与滚花部分（16）相邻的区域中形成在主轴（5）中的环形槽（19）也被填充有粘合剂（18）以进一步将内圈（8）固定到主轴（5），这改善了内圈（8）和主轴（5）之间的粘合。即使当球轴承是具有薄壁内圈（8）的微型轴承时，当粘合剂（18）固化时，也不必担心内座圈（8）变形，这提高了转子的旋转精度。

摘要： The present invention provides a bearing device reliable of shielding any material or fluid from moving between a fluid passage within a fluid system housing and an outside of the housing. In the above bearing device, a roller bearing (12) equipped with sealing plates (17) is fitted into a coupling bore (11) in an intake pipe (1) serving as the housing so that the roller bearing (12) can bear a shaft (6) of a butterfly valve disposed in a fluid passage (2) within the intake pipe (1). The outer race (13) and the inner race (14) of the roller bearing (12) are formed with annular grooves (21, 22), respectively, and O-rings (23, 24) are engagingly arranged on the interior of the annular grooves (21, 22), respectively. With the bearing device having this structure, the O-rings (23, 24) can prevent air, etc. from permeating into the intake passage (2) even though clearance (a, b) occurs in the engaged sections due to a dimensional error, difference in thermal expansion, etc.
