Title:
OPERATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/203886
Kind Code:
A1
Abstract:
One aspect of the present invention is an operation device comprising: a casing; an operation member having a shaft body portion extending in one direction, the operation member being capable of performing a tilting action about a first rotation axis; a first linked member having a first bearing portion that is supported by the casing so as to be capable of rotating about the first rotation axis, the first linked member being linked so as to rotate together with the operation member; a returning member for imparting, to the operation member, a returning force for returning the operation member to a neutral position; a biasing member for imparting the returning force to the operation member via the returning member; and a first rotation detection unit for detecting a rotation of the first linked member. The returning member is provided with: a bottom portion in contact with a first end portion, which is one extension-direction end portion of the operation member; and a receiving portion provided around the bottom portion, the receiving portion receiving an end of the biasing member. The casing has a receiving bottom portion for receiving the other end of the biasing member, the receiving bottom portion having a stopper that protrudes in the biasing direction of the biasing member. The bottom portion has a through-hole through which the stopper can be inserted, and therefore, a pushing action can be reliably restricted while ensuring the range of the tilting action of the operation member.
