A toggle block position adjusting method for a jaw crusher capable of carrying out the adjustment of the position of the toggle block over a wide range without making a device larger and applicable to a large-sized crusher, and a device for use in the method. A technique for adjusting the position of a toggle block of a jaw crusher for use in a method for adjusting the position of a toggle block supporting one end of a toggle plate which is connected to a lower end portion of a swing jaw at the other end thereof, the method being implemented with a device having a push-out block positioned on the back side of the toggle block and adapted to be moved in a direction in which the toggle block is moved back and forth and a pair of hydraulic cylinders connected at one end thereof to the ends of the toggle block located in a direction perpendicular to a direction in which the toggle block is moved back and forth and adapted to be extended and contracted in a direction in which the toggle block is moved back and forth, the method comprising the steps of advancing the push-out block to thereby push out the toggle block toward the toggle plate, causing the hydraulic cylinders to contract to thereby pull in the toggle block, and inserting a shim in a gap produced between the back of the toggle block and the front of the push-out block.
