Operation device comprising lever

An operation device comprising:

• a lever configured to be tiltable;
• a substrate having a surface;
• a first resistor having a strip shape and disposed on the surface of the substrate to extend in a first direction;
• a first actuator configured to rotate in accordance with tilting of the lever;
• and
• a first holder configured to hold a first slider and cause the first slider to slide on a surface of the first resistor by moving in the first direction via a first drive transmission part in accordance with rotation of the first actuator,
• wherein the first drive transmission part includes
• a first protrusion having a cylindrical shape, integrated with the first holder, and protruding in a second direction that is orthogonal to the first direction, and
• a first engagement portion integrated with the first actuator and including a pair of holding pieces configured to hold the first protrusion from both sides in the first direction, and
• wherein a first holding piece of the pair of holding pieces of the first engagement portion is more elastic than a second holding piece of the pair of holding pieces.
