Title:
DEVICE FOR DETECTING TRAVELLING POSITION BETWEEN FURROWS
Document Type and Number:
Japanese Patent JP3670347
Kind Code:
B2
Abstract:
PURPOSE: To perform an assembling work quickly installing variable resistors corresponding to left and right detecting levers without mistake.
CONSTITUTION: This position detecting device is obtained by providing base end parts of left and right detecting levers freely rotatably supported by a major body case 21, where the rotation angles are detected by variable resistors 27, 28, arranging the variable resistors 27, 28 at the left and right symmetrical positions and outside parts of holders 30, 32 which support a mobile contact point 29 to their right side, at the left and right symmetrical positions, and fixing left and right common resistor body plates 31 on which resisting membranes 31a are formed in same area, in an inclined state so as to make them symmetric. As a result, mistakes in assembling are prevented as much as possible and the efficiencies of assembling works are improved.
