| Zusammenfassung: | Disclosed is a chisel pin apparatus which can be inserted into a chisel housing in an orthogonal direction to an operation direction of a chisel to limit an operation range of the chisel of which a rear end is installed in the chisel housing to be able to orthogonally reciprocate. The chisel pin apparatus comprises: a first member of a cylinder form and a second member of the cylinder form; an elastic member to absorb an impact transmitted from the first and the second member, wherein the first and the second member are mounted on both sides respectively; and a first fixing member and a second fixing member connected to a front end and a rear end of the elastic member respectively, to fixate the first and the second member to the elastic member.
