Title:
THROTTLE DEVICE OF ENGINE
Document Type and Number:
Japanese Patent JP2023114214
Kind Code:
A
Abstract:
To provide a throttle device of an engine capable of fixing an excitation conductor to a throttle valve at a predetermined phase angle, eliminating the need of a holder or an excitation conductor portion of a complicated shape, and preventing erroneous detection due to heat or vibrations.SOLUTION: A throttle device 1 is equipped with a throttle sensor 10 that has an excitation conductor at an end portion of a throttle shaft 4, and a substrate 13 equipped with a magnetization conductor 15 opposite to the excitation conductor and a signal detection conductor 16. The throttle device 1 is further equipped with an excitation conductor portion 14 that is formed by non-magnetic material and is disposed oppositely to the circuit substrate 13. The excitation conductor portion 14 is equipped with a cylinder portion 14a along an axis of a throttle shaft 4, a plane portion 14b extending from an end portion of the cylinder portion 14a, a bottom portion 14c opposite to the plane portion 14b, and a rotation regulating hole 14e bored on the bottom portion 14c. A rotation regulating projecting portion 4a formed at an end portion of the throttle shaft 4 and the rotation regulating hole 14e of the excitation conductor portion 14 are fitted with each other, and the rotation regulating projecting portion 4a projects out into the cylinder portion 14a of the excitation conductor portion 14.SELECTED DRAWING: Figure 7
