DETECTION DEVICE FOR DOOR HANDLE

摘要

PROBLEM TO BE SOLVED: To provide a detection device for a door handle that reduces an interference between a first sensor part and a second sensor part.SOLUTION: A first sensor part 11 includes a core 110 manufactured by a material capable of increasing permeability in order to make a size small. A second sensor part 12 includes: plural bent parts including a first bent part 121 bending the second coil in such a manner to reciprocate in a state parallel to a stretching direction of the first coil 111 and to be superposed with each other in respect to the first coil 111 and at least second bent parts 122, 123 provided in such a manner to be located at one side and/or the other side in a stretching direction of the first bent part 121. The second bent parts 122 and 123 make up a densely winding structure for the first bent part 121.
