Abstract
A handle returning apparatus includes an input member rotating in conjunction with an operation handle operated to rotate in first and second directions including a neutral position, and a spring member including a plurality of spring portions integrally formed and including different spring forces, each of the spring portions including first and second spring end portions separating from each other in a circumferential direction and being configured to generate a returning force for returning the operation handle to the neutral position by being resiliently deformed on a basis of the rotation operation of the operation handle to bias the input member in a state where one of the first and second spring end portions engages with the input member and the other engages with a fixation member. The plurality of spring portions is selectively switchable therebetween to generate the returning force depending on a condition of the rotation operation.
