<p>PROBLEM TO BE SOLVED: To provide a crusher and a crushing method capable of efficiently crushing an object to be crushed by preventing leakage of crushing force generated from a crushing force generating member.SOLUTION: A crusher includes a wedge member 6 which receives crushing force generated from a crushing force generating member 4 disposed in an inside of a drilled hole 3 formed in an object 2 to be crushed in a first direction Z1 and is movable in a second direction Z2 different from the first direction Z1 in the drilled hole 3, a movable member 5 which is slidably provided in the inside of the drilled hole 3 with respect to a tilt surface 621 formed on the wedge member 6 and presses an inner wall of the drilled hole 3 by moving to the inner wall side of the drilled hole 3 while sliding on the tilt surface 621 in accordance with movement of the wedge member 6 to the second direction Z2 so as to crush the object 2 to be crushed, and a seal mechanism 7 which adheres a seal member 9 to the inner wall of the drilled hole 3 by swelling an outer end of the seal member 9 arranged between the wedge member 6 and the crushing force generating member 4 in the drilled hole 3 to the inner wall side of the drilled hole 3 so that sealing is performed.</p> |
