PROBLEM TO BE SOLVED: To realize a structure for changing the returning force to a neutral position, according to the operating volume of an operation member, using less space. SOLUTION: When the operation member is operated toward a first direction from a first neutral position, and when the operation member is operated toward a second direction from a second neutral position, a first biasing member and a second biasing member are arranged at a retaining member, respectively, so that a displacement direction of the first biasing member and a displacement direction of the second biasing member are to be in the same direction, and at the same time, so that a part of a displacement orbit of the first biasing member, when the operation member is operated in the first direction, is overlapped with a part of a displacement orbit of the second biasing member, when the operation member is operated in the second direction.
