Abstract: A force sensing apparatus with bridge portion comprises a first case, a second case, and a force sensing module. The first case comprises a first annular portion, a first bridge portion, and an inner wall portion. The first bridge portion is connected to an outer periphery of the first annular portion. The inner wall portion is connected to an inner periphery of the first annular portion. The second case comprises a second annular portion, a second bridge portion, and an outer wall portion. The second bridge portion is connected to an inner periphery of the second annular portion. The outer wall portion is connected to an outer periphery of the second annular portion. A stiffness of the second annular portion along an axial direction is greater than a stiffness of the second bridge portion along the axial direction. The second case is disposed on the first case along the axial direction to form a space. The force sensing module is disposed in the space.
