| 摘要 |
<p>The present invention forms a spacer (50) and a drive shaft (51) by insert-molding a magnetic-field-generating body (30) using a non-magnetic resin member. The magnetic-field-generating body (30) slides in a movement direction (X) in a state of close contact with a straight section (21) of a second fixed magnetic body (20) with the spacer (50) interposed therebetween; hence, there is no rattling.</p> |
