Abstract
A magnetostrictive load sensor includes an upper casing, a lower casing, a coil, and a bobbin. The upper casing having an approximate bell shape has an upper end that is provided with an opening and a lower end that is provided with a notch. The lower casing includes a disk-shaped member and a bar-shaped member that are integral with each other. The coil is formed by winding a conducting wire around the bobbin. A predetermined position of the bobbin is provided with a lead wire outlet for taking out the conducting wire of the coil. A method of manufacturing the magnetostrictive load sensor includes inserting the bar-shaped member into the axial center of the bobbin, and covering the lower casing with the upper casing. In this way, the notch of the upper casing and the lead wire outlet of the bobbin are fitted with each other. An upper end of the bar-shaped member projects through the opening of the upper casing.
