摘要： A liquid level detecting device includes a sensor housing having a circular rotation recess, a circular holder which is fitted in the rotation recess and held rotatably by the sensor housing, a float arm, a float, a magnet, and a Hall element. The sensor housing has a lock groove and a pair of insertion holes. The holder has a pair of flanges which project in opposite directions from an outer circumferential surface of the holder and are engaged with the lock groove and prevented from coming off the rotation recess by setting the flanges opposed to the respective insertion holes, fitting the flanges into the rotation recess, and then rotating the flanges. The holder has a pair of support projections which come into contact with a bottom surface of the rotation recess.

摘要： A mounting structure includes a mounting object member and a liquid level detecting device. The liquid level detecting device includes a device main body which is mounted on a mounting surface of the mounting object member and a holder which is attached to the device main body and is rotated according to a variation of a liquid level of liquid stored in a tank. The mounting object member has a pair of lock portions which lock side portions of the device main body respectively and a pair of projections. The device main body has a pair of hooks. The hooks have respective claws. The hooks are formed closer to the mounting surface in a thickness direction of the device main body than a holder movable area of the device main body.

摘要： A sensor housing of a fluid level sensor includes a peripheral wall portion and a lead wire inserting portion. The peripheral wall portion forms a hollow space penetrating in the depth direction of the sensor housing and is formed in a manner of surrounding the periphery of a terminal area of a lead frame. The lead wire inserting portion is formed by notching the peripheral wall portion in the depth direction of the sensor housing. The lead wire inserting portion consists of a first inserting portion into which a lead wire extending from the terminal area is inserted and a second inserting portion into which the lead wire is inserted after passing through the first inserting portion and holds the lead wire in a manner of bending the lead wire in a crank shape. With this configuration, the fluid level sensor can prevent leak current generated on the terminal area and thus can connect a conductive wire (the lead wire) used for connection with an external circuit with the terminal area in good condition.

摘要： A liquid surface level sensor includes a plurality of piece portions provided at both ends of the liquid surface level sensor in a width direction, and a plurality of elastically deformable hook portions formed to elongate from both end sides in a first height direction. A pump holder includes a plurality of claw portions formed in a claw shape by bending front end sides in an intra-width direction of the liquid surface level sensor, and a plurality of convex portions on a side of the first height direction of the plurality of claw portions. A plurality of hook portions is elastically deformed in contact with the plurality of convex portions by sliding the liquid surface level sensor in a second height direction, the plurality of hook portions gets over the plurality of convex portions and restores from an elastically deformed state by further sliding the liquid surface level sensor.
