Abstract: A shock absorber includes a cylinder, a spring, a receiving member, a sensor, and a coupling member. The sensor includes a coil portion, and a core portion. The coupling member is formed integrally with the core portion. A recessed portion is formed in one of the receiving member and the coupling member, a protruding portion facing the recessed portion is formed in the other one of the receiving member and the coupling member, and the receiving member and the coupling member are coupled to each other via the recessed portion and the protruding portion.

Abstract: A damping force generation structure includes a damping force generation mechanism, and a damping force adjustment mechanism. The damping force adjustment mechanism includes a drive mechanism configured to be able to drive the valve body, and a coupling member having a first end fixed to the drive mechanism and a second end fixed to the fixing member, thereby coupling the drive mechanism and the fixing member. At least one of a position of the damping force generation mechanism relative to the fixing member, a position of the coupling member relative to the fixing member, and a position of the drive mechanism relative to the coupling member is adjustable in the advancing and retracting direction of the valve body by a position adjustment mechanism.

Abstract: A control device controls a damping force of a damping device, which damps a force generated between a vehicle body of a two-wheeled vehicle and at least one of a front wheel and a rear wheel, by using an angular velocity of rotational movement in a front-rear direction of an unsprung part of the two-wheeled vehicle, which is generated due to a difference between a velocity in an up-down direction of the front wheel and a velocity in the up-down direction of the rear wheel.
