A throttle control apparatus for an engine on a vehicle is provided, in which the number of component parts in the position detection means and the driven means is reduced to improve the accuracy in its position control and at the same time an integrated wiring is achieved and connectors are aggregated. The position detection means for detecting the position of a control valve, the driven means for controlling the position of the control valve, the means for processing control signals, an output from the position control means for controlling the position of the control valve are disposed within a sealed space defined by a body supporting a control valve shaft, and a cover. Based on the fact that the number of component parts of the position detection means may be reduced, the mechanical hysteresis and electrical hysteresis may also be reduced to improve the accuracy in controlling the control valve position, and it is possible to aggregate the connectors.

A pressure-sensitive adhesive articleincludes a release sheetconstituted from a releasing agent layerand a base material, and a pressure-sensitive adhesive sheetconstituted from a pressure-sensitive adhesive layerand a pressure-sensitive adhesive sheet base. Such a pressure-sensitive adhesive articlehas a structure in which the pressure-sensitive adhesive sheetis laminated on the release sheetso that the pressure-sensitive adhesive layeris in contact with the releasing agent layer. The releasing agent layeris composed of a material containing substantially no silicone compound. The releasing agent layeris mainly composed of an elastomer and has a Young's modulus of 1.5 GPa or less. Preferred examples of the elastomer include polybutadiene rubber (especially, 1,4-polybutadiene rubber), polyisoprene rubber, and ethylene propylene rubber. The release sheethas excellent releasability and has little adverse effect on electric components and the like.

An throttle valve is controlled by using an electric actuator. A cover for covering one end side of the throttle valve shaft is attached to a side wall of a throttle body. a throttle position sensor unit and an electronic control module for controlling the throttle valve is attached to an inner face of the cover. The throttle position sensor and the electronic control module are contiguous to each other and connected at a position contiguous thereto. The cover is provided with a connector portion for external connection of the electronic control module. A group of lead frames constituting terminals of the connector portion are embedded in the cover. Power source is supplied to a motor via the connector portion for external connection, the electronic control module and intermediary connectors provided at the cover.
