Title:
INSTRUMENT DEVICE
Document Type and Number:
Japanese Patent JP2015049084
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an instrument device capable of alleviating influence on indication of a pointer without deteriorating indication characteristics and responsiveness of an instrument body.SOLUTION: An instrument device includes: a pointer type instrument 10 for displaying speed of a vehicle; a circuit board 12 electrically connected with the pointer type instrument 10; a detection body composed of magnets 14 that rotate with a rotation cable 9 transmitting rotation of speed of the vehicle and is provided in parallel with the instrument body 19 of the pointer type instrument 10; and a detector 15 for detecting rotation of the detection body 14. The detector 15 is implemented on the circuit board 12. A magnetic pole to be a different pole in the thickness direction of the detection body 14 opposing to the detector 15 is magnetized onto the detection body 14. Therefore, magnetic interference with the instrument body 19 becomes small, responsiveness of the instrument body 19 is not deteriorated, and influence on indication of a pointer 18 can be alleviated.
