To provide a grasping mechanism and a grasping device, which are capable of generation and extinction of a high magnetic flux necessary to control the viscosity of a magnetic fluid while being compact, cause no magnetic flux leakage to the outside, can surely grasp a fragile object and a small object and excel in versatility and practicability.SOLUTION: A grasping mechanism 10 comprises a bag body 11 having flexibility, a magnetic fluid 12 enclosed in the bag body 11, a permanent magnet 13 arranged on one side of the bag body 11, and a rotary driving part 16 that rotates the permanent magnet 13 to increase or decrease the amount of a magnetic flux acting on the magnetic fluid 12. A grasping device 31 comprises a plurality of grasping mechanisms 10, in which each grasping mechanism 10 is inclined downwardly toward the center side of the plurality of grasping mechanisms 10.SELECTED DRAWING: Figure 1
【課題】小型でありながら磁性流体の粘度の制御に必要な高い磁束の生成、消滅が可能であり、外部に漏れ磁束を発生させることもなく、壊れ易い対象物や小さな対象物でも確実に把持することができる汎用性、実用性に優れた把持機構及び把持装置を提供する。【解決手段】柔軟性を有する袋体11と、袋体11に封入された磁性流体12と、袋体11の一側に配置された永久磁石13と、永久磁石13を回転させることによって磁性流体12に作用する磁束の量を増減させる回転駆動部16とを有する把持機構10及び複数の把持機構10を有し、各把持機構10が、複数の把持機構10の中心側に向かって下方傾斜している把持装置31。【選択図】図1
