The user H can stand up more easily by standing up while changing the gripping position. Then, when the user H operates the operation unit, a third state in which the seat 20 is locked at the second seat position SP2 is formed as shown in FIG. For this reason, in the third state, the waist of the user H is supported by the seat 20 at the second position.

  Next, in a state where the waist of the user H is supported by the seat 20 in the second position, or in a state where the user H stands up without being supported by the seat 20, the user H maintains a standing posture. While walking, the upper gripping portion 16 of the frame structure 10 is used. In one example, the user H walks using the upper gripping portion 16 or the like while maintaining the middle waist state as a standing posture. For this reason, walking of the user H is assisted by the body assisting device 1.

  Next, as shown in FIG. 9, the user H performs an operation in a standing state using the body assisting device 1, for example. The operation in the standing state includes, for example, an operation of moving an article on the front side of the body assisting device 1 and housework. The user H performs housework near the sink SK as an example of the operation in the standing state.

  The user H first walks to the front of the sink SK using the body assisting device 1 to form a fourth state in which the end surface 12C of the frame structure 10 is close to the sink SK. When the body assisting device 1 comes into contact with the sink SK, the shock due to the contact is alleviated by the shock absorbing unit 60. For this reason, an impact caused by contact with the sink SK is not easily transmitted to the body through the frame structure 10. In addition, since the shock absorbing unit 60 is provided to be rotatable around an axis along the height direction of the body assisting device 1, the body assisting device 1 can be easily moved along the sink SK. For this reason, it is easy to arbitrarily change the position of the body assisting device 1 with respect to the sink SK.

  Next, in a state where the waist of the user H is supported by the seat 20 in the second position, the user H performs an operation of washing tableware, which is an example of housework. When the user H puts the upper limb UL on the armrest 70 and performs the operation in the standing state, the burden on the operation in the standing state is reduced. Further, the upper end of the front support frame 14 is provided behind the lower end of the front support frame 14 in the front-rear direction of the body assisting device 1 by the curved portion 14 </ b> C provided in the front support frame 14. For this reason, the distance between the user H and the armrest 70 can be reduced in a state where the waist of the user H is supported by the seat 20 in the second position, and the armrest 70 can be easily used in the operation of the user H standing up. .

  In the body assistance device 1, the frame structure 10 in the state where the waist of the user H is supported by the seat 20 at the second position is greater than the state where the waist of the user H is supported by the seat 20 at the first position. The distance from the end face 12C to the user H can be reduced. For this reason, the user H can easily perform the operation in the standing state using the body assisting device 1.

  The user H operates the operation unit so that the seat 20 moves from the second seat position SP2 to the first seat position SP1 after finishing the walking and standing motions using the body assisting device 1. Then, the user H changes from the seat 20 to the seat CH or the like. As described above, the user H ends the use of the body assisting device 1.
