Lever operation device

A lever operation device, comprising:

• a housing;
• a lever portion which is attached to the housing and on which a first rotation operation about a first shaft is performed,
• a magnet attached to a tip portion of the lever portion on a tip side relative to the first shaft;
• a magnetic sensor that is arranged in the housing so as to be located on extension from the tip portion and detects movement of the magnet due to the first rotation operation performed on the lever portion;
• and
• a detent portion provided on the lever portion and comprises a detent tip end portion and an elastic portion, the detent tip end portion generating a detent by moving with a tilt in a direction of the first rotation operation from a direction of extension from the tip portion of the lever portion and coming into contact with a detent surface of a detent wall arranged on the housing, and the elastic portion applying an elastic force to the detent tip end portion.
