| 主权项 | 1. A magnetic circuit comprising: a first magnetic body configured to include (i) a magnet and a yoke plate, or (ii) the magnet and two yoke plates; and a second magnetic body, wherein the yoke plate forms an opening space at a position facing the second magnetic body, wherein the magnet is disposed in the opening space or at a position sandwiched between the two yoke plates, wherein one of the first magnetic body and the second magnetic body is provided in a movable body, wherein the other of the first magnetic body and the second magnetic body is provided in a support member, wherein the support member supports the movable body by causing the first magnetic body and the second magnetic body to be magnetically attracted to each other, wherein the support member has a guide surface that is inclined with respect to a horizontal plane perpendicular to a height direction of the movable body, and wherein the movable body includes a sliding portion that slides on the guide surface. | ||
