Abstract:
1. A handle returning apparatus comprising: an input member rotating in conjunction with an operation handle that is operated to rotate in a first direction and a second direction including a neutral position; and a spring member including a plurality of spring portions which is integrally formed, the plurality of spring portions including different spring forces from one another and extending around a support shaft of the input member, each of the plurality of spring portions including first and second spring end portions separating from each other in a circumferential direction of the spring member, each of the plurality of spring portions 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 of the first and second spring end portions engages with a fixation member, the plurality of spring portions being selectively switchable therebetween to generate the returning force depending on a condition of the rotation operation of the operation handle.
