Problems solved by technology

However, if it is desired to perform press work on the strip-shaped base material in advance so as to be in an integrated state, the processing range of the base material is excessively expanded during the press process, which will cause many defects in the base material to be processed. wasted part
Therefore, it is expensive to manufacture

Abstract

The invention provides a rotation angle detection device. It is incorporated into the throttle device to detect the opening degree of the throttle valve, thereby reducing the manufacturing cost when manufacturing the rotation angle detection device. When forming the terminal main body (42, 52) connected to the magnetic detection member or the drive motor, and the connector part (45, 55) connected to the external connector, the above-mentioned terminal main body (42, 52) and the connector part can be (45, 55) are formed separately. Accordingly, the terminal main body (42, 52) is formed of a copper material having spring properties, and the connector portion (45, 55) is formed of brass. After forming the above-mentioned terminal main body (42, 52) and connector part (45, 55), they can be integrated with each other by means of the joint part (48, 58) for electrical joining. The plate thickness of the terminal main body ( 42 , 52 ) was set to 0.4 mm, and the plate thickness of the connector portion ( 45 , 55 ) was set to 0.6 mm.

Description

technical field [0001] The present invention relates to a rotation angle detection device assembled in a throttle device for detecting the opening degree of a throttle valve. Background technique [0002] There is known a throttle device for controlling the amount of air supplied to an engine of an automobile. The throttle device includes a butterfly valve type throttle valve whose rotation is controlled. The throttle valve of the butterfly valve type rotates a rotary shaft in accordance with the acceleration operation of the vehicle, and changes the valve opening degree in order to control the amount of air supplied to the engine. Therefore, such a throttle device is provided with a rotation angle detection device for detecting the opening degree of the throttle valve. In addition, the rotation angle detection device detects the opening degree of the throttle valve by detecting the magnetism that changes due to the rotation of the rotation shaft of the throttle valve. Ac...
