Manipulation device

A manipulation device comprising:

• a manipulation member including a manipulation body having a movable axis that allows an operation of the manipulation member in a manipulation direction according to a manipulation by a manipulator;
• a support body that supports the manipulation body movably in the manipulation direction;
• and
• a bias mechanism that applies a movable load to the manipulation body, the bias mechanism including:
• a movable member that operates by engaging with the movable axis of the manipulation body;
• a magnetism generating mechanism that faces the movable member with a gap provided therebetween, the magnetism generating mechanism including a coil that generates a magnetic field by being energized, and a first yoke disposed on one side of the movable member as to enclose the coil;
• and
• a magnetic viscous fluid provided in the gap, the magnetic viscous fluid filling a first part of the gap between the first yoke and the movable member, viscosity of the magnetic viscous fluid changing according to strength of the magnetic field;
• and
• a first buffering layer provided in the gap, the first buffering layer having hardness lower than hardness of the movable member, the first buffering layer being disposed on at least one of a surface of the first yoke and a surface of the movable member facing the surface of the first yoke.
