Document Type and Number:
Japanese Patent JP6740111
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a rotation mechanism which is configured to rotate a second object around a projection of a first object with the projection defined as an axis in a state where the projection is inserted into the second object, and capable of detecting the state where the projection is inserted into the second object, even if the second object is rotated.SOLUTION: In a rotation mechanism 1 including a first object 100 and a second object 200 and being configured to rotate the second object 200 around a projection 101 of the first object 100 with the projection 101 defined as an axis in a state where the second object 200 receives the projection 101, multiple magnets 300 are fixed along an intersection C between a plane that is orthogonal with a rotation axis L, and a surface of the projection 101, and at least one element 400 for detecting a magnetostatic field is fixed at any position in a portion F of the second object 200 facing the intersection C in the state where the second object 200 receives the projection 101.SELECTED DRAWING: Figure 1
