STROKE SIMULATOR

The present invention comprises: a piston provided in a cylinder hole; a lid member which closes an opening on the other side of the cylinder hole; and elastic members and which are provided between the piston and the lid member. The elastic members and comprise a first elastic member provided on the piston side of the cylinder hole, and a second elastic member provided on the lid member side of the cylinder hole. The second elastic member has a base portion provided in line with the first elastic member, and a protruding portion protruding from the piston -side end surface of the base portion. When the piston has moved in the axial direction to the lid member -side, the protruding portion touches the piston, undergoing compressive deformation, and the base portion subsequently undergoes compressive deformation.
