ジング構造。[Claims for Utility Model Registration] (1) A float guide shaft on which a float equipped with a magnet is fitted so as to be able to move up and down, and a reed switch operated by the magnet, which is bored in the float guide shaft in the axial direction. A housing structure for a float type liquid level sensor, comprising a hole for accommodating a mounted board, and a head part integrally molded with the float guide shaft to define an entrance of the hole, the hole having an axis line. a pair of opposing first walls extending along the direction and into which the substrate is fitted; and a pair of opposing first walls extending perpendicularly to the first walls into which the reed switch is fitted. It has a cross-shaped cross-sectional shape consisting of two walls,
A box-shaped peripheral wall portion is formed at the periphery of the entrance to define a cross-shaped opening corresponding to the cross-sectional shape of the hole, and at least a pair of opposing walls of the peripheral wall portion into which the substrate is inserted are formed. A housing structure for a float type liquid level sensor characterized by one part being formed higher than the other part. (2) A utility model according to claim 1, characterized in that a through hole is formed in the one wall portion of the peripheral wall portion through which a lead wire connected to the board is inserted. Housing structure of float type liquid level sensor.
