A toggle block adjustment arrangement for a jaw crusher is provided.

Provided is a jaw crusher driving device in which a driving torque can be transmitted reliably to a rotation driving shaft to perform a crushing operation by strongly fixing a hydraulic pressure motor between a body frame of a jaw crusher and a flywheel. The jaw crusher includes a fixed tooth, a movable tooth, a rotation driving shaft rotatably supported on a body frame, and a pair of flywheels provided in the rotation driving shaft. The driving device includes: a hydraulic pressure motor in which a rotation shaft portion can rotate in relation to a motor body when pressure fluid is supplied; a connector for connecting one flywheel of the pair of flywheels and the rotation shaft portion; and a torque arm provided between the body frame and the motor body so as to prevent the motor body from rotating about an axis of the rotation driving shaft.
