Patent ID: 8251271

Claim:
A nailing machine, comprising: a drive unit that drives a blade to strike a nail; a blade guide forming a portion of a passage through which the blade is guided; a guide plate that is attached on the blade guide to cover the portion of the passage; a magazine that is held with respect to the blade guide and that feeds a nail to the passage, wherein the nailing machine further includes a blade fixing unit that limits a movement of the blade when the guide plate is detached; and a plate member that is disposed to be adjacent with the guide plate, wherein the blade fixing unit is interposed between the guide plate and the plate member, wherein the blade fixing unit includes: a contact member; and a spring that urges the contact member, wherein the spring and the contact member are delimited in a space defined by the blade, the guide plate and the plate, and are covered with a lock plate, wherein the lock plate includes an inclined surface portion facing a surface of the blade above which the contact member is disposed, wherein the inclined surface is formed so that a distance between the inclined surface portion of the lock plate and the surface of the blade decreases toward a nail ejection direction, and wherein the contact member moves along the inclined surface portion due to an urging force of the spring so as to be caught between the inclined surface portion and the blade, thereby fixing the movement of the blade.
