PROBLEM TO BE SOLVED: To simplify calculation, to facilitate adjustment and to improve accuracy in the nose gap adjustment of a crusher having a jaw crusher, and to facilitate the alternation of a set value of the nose gap, moreover, to previously prevent a damage to the subject device due to overload. SOLUTION: In the nose gap adjusting device of the crusher having the jaw crusher constituted by forming a crushing chamber having a V-shaped cross section by a stationary blade and a freely slidable dynamic blade and by having a jaw crusher constituted by supporting the upper end part of a jaw attached to the dynamic blade freely eccentrically movably and freely movably the lower part by the circular arc motion of the other end with one end of a freely movable toggle plate as a base point and adjusting the nose gap between the stationary blade and the dynamic blade by moving the jaw through the toggle plate, a detecting means 28 for detecting the contact of the stationary blade with the dynamic blade, a detecting means 22 for detecting an operation supporting position of the toggle plate and a control device 30 for calculating a nose gap value on the basis of the operation supporting position at contact and outputting the calculated nose gap value at the time of nose gap adjustment, are provided.
