Abstract: A liquid level detector includes a casing having a first regulatory section and a second regulatory section, a float that has its upward and downward displacement restricted by contact with the first regulatory section or the second regulatory section, a magnet body that is held by the float, and a switch mechanism that is switched between an on-state and an off-state. A first distance from a switching plane to the first regulatory section and a second distance from the switching plane to the second regulatory section are both longer than a length from one magnet end face to a bottom end section.

Abstract: A liquid level detector includes a casing, a float, a magnet body, and a switch mechanism. The casing includes a tube section. The float is displaced upward or downward along a gravity direction. The magnet body is held by the float. The switch mechanism is accommodated in the tube section and is switched between an on-state and an off-state. The casing includes a first casing part and a second casing part. The first casing part includes the tube section, a first locking section that is formed radially outward of the tube section, and a first guide section that is formed at a tip of the tube section in an extending direction. The second casing part includes a second locking section and a second guide section.

Abstract: A welding method heats and pressurizes a contacting portion, where a first member and a second member made of resin are in contact with each other, by a pressing tool. The welding method has forming a step, forming a recessed portion, crushing a protrusion, and filling the recessed portion. The step is defined between the first member and the second member by providing the protrusion to the first member. The recessed portion is provided in a tip of the pressing tool. The protrusion of the first member is crushed in the recessed portion by being pressed toward the second member using the pressing tool. The recessed portion is filled with the molten portion of the first member and the molten portion of the second member such that a rim of an outer periphery of the recessed portion is dug into the first member and the second member.
