摘要： There is provided a load sensor that can make accurate measurement without being affected by unnecessary external force and moreover has a simple construction. The load sensor includes a strain generating element (3) which is formed integrally with an installation section (9) attached to an object to be measured and is displaced according to the weight or load of the object to be measured, a sensor plate (13) which is connected to the strain generating element (3) and is distorted according to the displacement of the strain generating element (3), and a strain gauge attached to the sensor plate (13). The strain generating element (3) is placed on one end side of the installation section (9) with the center thereof aligned with the axis of the installation section (9). On the inside of the strain generating element, a reception section (5) for housing the sensor plate is formed, and the sensor plate (13) is housed in the reception section while being held by a holder (100). At this time, the sensor plate (13) is connected to the center of the strain generating element (3) with the center thereof aligned with the axis of the installation section (9) and the center of the strain generating element (3). On the other hand, an outer peripheral edge (13b) of the sensor plate (13) is held by an inner peripheral edge (100a) of the holder (100), and an outer peripheral surface (100b) of the holder (100) is joined to an upright wall at the outer edge of the reception section (5). The holder (100) preferably has a cushioning function.

摘要： The object of the present invention is to provide a maximum value storage sensor when detecting the maximum strain by generating an invariable electrical resistance change correlative to the strain of the detection object in a conductive body having a plurality of conductive elements. The maximum value storage sensor of the present invention has; a conductive body having a circuit which gives correlative resistance changes corresponding to the sequential cutoff of a plurality of conductive elements each having a given electrical resistance arrayed in parallel; a cutting means for cutting the conductive elements of the conductive body; and a structure for allowing one of the conductive bodies and the cutting means to move relatively to each other. The sensor is attached to an object component member in a structure so as to generate relative movements between the conductive body and the cutting means which correspond to any strains exerted upon the object component member, and it detects maximum strains in the object component member by allowing the cutting means to sequentially cut off the conductive elements of the conductive body corresponding to an amount of the relative movement.
