Abstract
A lever operation device includes a lever main body on which a first rotation operation about a first shaft is performed, a bracket portion that includes an insertion opening for insertion of the lever main body and a through-hole in communication with the insertion opening, a housing which rotatably holds the bracket portion and on which a detent wall including a detent surface is arranged, and a detent portion that is inserted into the through-hole and includes a detent tip end portion in contact with the detent surface, a detent base end portion in contact with the lever main body inserted into the insertion opening of the bracket portion, and an elastic portion applying an elastic force, which is generated by being sandwiched and compressed by the detent surface and the lever main body, to the detent surface and the lever main body.
