Abstract
A resistor substrate for a variable resistor of the enclosed type which may be employed in a throttle sensor of an automobile. The resistor substrate has a disk portion and a rectangular apron provided at a circumferential portion of the disk portion. The apron is stepped with respect to the disk portion to form a reduced thickness portion, and a plurality of projections each having an arcuate section in a widthwise direction are formed at end portions of the reduced thickness portion of the apron. A plurality of terminals are embedded at base portions thereof in the disk portion and extend along a surface of the reduced thickness portion of the apron. The terminals individually have arcuate protruded portions formed therein in accordance with a configuration of the projections of the apron, and the projections individually have lateral holes formed therein in an opposing relationship to the protruded portions of the terminals such that they extend to the protruded portions. When the resistor substrate is fitted in the casing, the apron of the resistor substrate contacts with a flange portion provided on the casing.
