Assistance apparatus

An assistance apparatus configured to assist a transfer operation of a care receiver, comprising:

• a base on which the care receiver places his/her feet;
• a support arm section configured to support a part of the care receiver's body and operate in a stand-up direction for standing up the care receiver or a seating direction for seating the care receiver;
• an actuator connected to the base and the support arm section and configured to drive the support arm section;
• and
• a buffer mechanism installed in at least one member among a plurality of members from the base to the support arm section connected via the actuator or installed between the members connected to each other from the base to the support arm section via the actuator and configured to absorb at least a part of a driving force of the actuator when an external force is applied in the stand-up direction to the support arm section driven in the seating direction by the actuator,
• wherein the buffer mechanism absorbs the driving force of the actuator to maintain a position of the support arm section, and
• wherein the buffer mechanism comprises a bracket with a fixed attachment portion attached to one of the members in a non-displaceable manner and a displacement attachment portion that is attached to other one of the members in a displaceable manner,
• wherein the bracket comprises:
• the firxted attachment portion attached to the actuator which is the one of the members,
• the displacement attachment portion attached to the base which is the other one of the members, and
• a rotation fulcrum provided spaced apart from the displacement attachment portion and attached to the based in a non-displaceable but rotatable manner;
• and
• the bracket is rotatable around the rotation fulcrum in a direction in which the fixed attachment portion rises.
