摘要： Provided is a liquid level detection device with excellent bonding strength between components. This liquid level detection device is provided with a holder which has a magnet inside and which rotates in response to displacement of a float floating in the liquid the level of which is to be measured, a main body unit which rotatably supports the holder and has a magnetic detection element which detects magnetic pole change accompanying rotational movement of the magnet, and a cover which covers the holder and which is attached by welding to the main body unit to prevent the holder from falling away from the main body unit. The cover is welded to the main body unit by melting protrusions formed on the main body unit.

摘要： Provided is a liquid level detection device which is configured so that an arm can be easily mounted to a holder after the holder is pivotably mounted using a cover and a main body portion. An end of a float arm is bent at a substantially right angle, and the end side of the float arm is defined as a first end portion. The portion of the float arm which is located closer to the center of the float arm than the first end portion is defined as a second end portion. A first arm mounting portion to which the first end portion is affixed and second arm mounting portions to which the second end portion is affixed are provided to a holder. A stopper for restricting the pivot range of the holder is provided to a main body portion. A first stopper which comes into contact with the stopper is provided to the holder. The first arm mounting portion and the first stopper are provided on a line passing through the pivot axis of the holder and perpendicular to the pivot axis.

摘要： Provided is a liquid surface detection device providing for compactness and enabling a reduction in displacement of a rotating shaft of a magnet. In the liquid surface detection device, which is provided with a holder rotating in response to displacement of a float, said displacement accompanying a change in a liquid surface, which is provided with a magnet affixed to the holder and rotating along with the holder, and which is provided with a magnetic detection element detecting a magnetic force change accompanying the rotating motion of the magnet, said liquid surface detection device is provided with: a body section that provides on the holder, first and second rotating sections sandwiching the magnet therebetween in the rotary axis direction of the magnet, said body section being provided with a first rotary support section that places the magnetic detection element opposite the magnet in the rotary axis direction of the magnet, and that rotatably supports the first rotation section of the holder; and a cover that is affixed to the body section, and is provided with a second rotary support section that rotatably supports the second rotating section of the holder.
