Support structure for load measurement sensor

A support structure for a load measurement sensor which supports the load measurement sensor, comprising:

• a sensor body that detects a load applied to a seat;
• and
• an extension shaft portion extending from the sensor body, by way of a support bracket in a state where the extension shaft portion is positioned at a side portion of the sensor body;
• the sensor body comprising:
• a deformation portion which is a portion of bendable material and is deformable to be curved inward in a radial direction of the extension shaft portion by receiving the load;
• and
• a regulation portion which is a portion of material which is positioned inside relative to the deformation portion in the radial direction and comes into contact with the deformation portion to regulate a deformation amount of the deformation portion;
• the regulation portion being disposed in an axial direction of the extension shaft portion at a position that includes a load center point of the load applied to the deformation portion by the seat;
• wherein:
• the support structure for the load measurement sensor comprises:
• a pressing portion which is positioned at an outside of the deformation portion in the radial direction and presses the deformation portion inward in the radial direction when the load is applied to the seat;
• and
• a load transmission member that is positioned between the deformation portion and the pressing portion in the radial direction to widen a pressing area in which the pressing portion presses the deformation portion;
• the load transmission member is provided so that both ends of the load transmission member in the axial direction are positioned at an inside of both ends of the regulation portion in the axial direction;
• and
• a length of the load transmission member in the axial direction is longer than a length of the pressing portion in the axial direction.
