Title:
WINDOW OPENING/CLOSING DETECTING DEVICE
Document Type and Number:
Japanese Patent JP2010129004
Kind Code:
A
Abstract:

To improve assemblability and to reduce cost by suitably storing and holding even a magnetism collector with a large dimensional error.

This window opening/closing detecting device is provided with a Hall sensor disposed at the end to detect the magnetic force of a magnet provided at a crescent lock opening/closing lever of a window sash, and discriminates opening/closing of a window based on a detection signal of the Hall sensor and carries out radio transmission. The window opening/closing detecting device is composed of a device body and a cover member. The conical magnetism collector 26 is disposed at the front face of the Hall sensor provided at the device body. The magnetism collector 26 is included in a holder member 28 and stored in the cover member. The holder member 28 includes a locking claw part 54 fittingly holding the edge of a large diameter incident surface of the magnetism collector 26, and a conical receiving hole 56 fittingly holding a conical top part on the small diameter emission surface side of the magnetism collector 26 in an axially displaceable manner. The conical receiving hole 56 of the holder member 28 is formed with a plurality of axial split grooves at an extended portion on the tip top side, and deformed to spread by the push-in of the magnetism collector 26 to absorb the dimensional error.
