Title:
グリップ開度検出装置
Document Type and Number:
Japanese Patent JP6982536
Kind Code:
B2
Abstract:
To improve reliability of a grip opening detection device while reducing the number of components and a manufacturing cost of the device.SOLUTION: An opening detection mechanism 16 constituting a grip unit 10 has: a first rotor 46 connected to a grip handle 12; a second rotor 48 which is meshed with the first rotor 46, and rotates in conjunction with the first rotor; a magnet 50 fitted to the second rotor 48; and a detection sensor 52 which is arranged so as to oppose one end part 50a of the magnet 50 in an axial line direction of the second rotor 48. A magnetic body 90 separates from the detection sensor 52, and is movably arranged so that a distance between the magnetic body 90 and the magnet 50 is changed on an axial line G. Then, a magnitude Sc of magnetic flux density detected by the detection sensor 52 is changed by the movement of the magnetic body 90 to a direction orthogonal to the axial line G of the second rotor 48 by an operation of a changeover switch 18, and a switch position of the changeover switch 18 is confirmed on the basis of the magnitude Sc of the magnetic flux density.SELECTED DRAWING: Figure 3
