摘要： An object of the present invention is to provide an electronically controlled throttle device having a structure in which a resin cover is separated into a cover body portion and a connector portion, and has improved watertightness without increasing the size of the device. The electronically controlled throttle device of the present invention includes a motor 2, a throttle valve 4, a chassis 1, a resin cover 12, and a circuit board 104. The resin cover 12 has a first cover portion 12-1, a second cover portion 12-2, and a conductive wire 22 provided at a connection portion between the first cover portion 12-1 and the second cover portion 12-2. The connection portion is joined by forming a molten portion 23 around the conductive wire 22.

摘要： An object is to provide a type of device capable of properly cooling a bearing of a throttle body even under a condition that the throttle body receives heat of high-temperature intake air or exhaust gas. In the present invention, an engine coolant passage that guides a coolant of an engine is provided integrally with a member fixing a bearing to be adjacent to a circumferential wall of the bearing of the member fixing the bearing, which supports a throttle shaft, and heat transferred from the bearing (or likely to be transferred to the bearing) via the member fixing the bearing is carried away to the outside of a throttle body by the engine coolant.
