PROBLEM TO BE SOLVED: To enhance detection accuracy of liquid level.SOLUTION: A liquid level detection device 100 for detecting liquid level comprises: a fixed body to be fixed; a rotor 30 which is supported by the fixed body and rotates; and an arm 50 for connecting the rotor 30 and a float and capable of being elastically deformed. The rotor 30 comprises an insertion hole 35b into which the arm 50 is inserted, and an engagement structure for engaging the arm 50. The arm 50 comprises an engagement part 52 which is engaged with the engagement structure and extends along a certain direction, and an insertion part 54 which is bent to the engagement part 52 and inserted into the insertion hole 35b. The insertion part 54 has a support portion 54b supported by an inlet 36 of the insertion hole 35b from its bending direction, and applies elastic resilience to the insertion hole 35b at any portion separated from the engagement part 52 farther than the support portion 54b and opposite to its bending direction. The engagement part 52 applies elastic resilience to the engagement structure at any portion separated from the insertion part 54 farther than the support portion 54b and opposite to the direction of insertion part 54. |
