A nailing machine, in which a part constituting a nose is changed so as to increase the service life of a driver blade for driving a nail. The nailing machine includes a nose having a nose hole in which the nail is supplied, and the driver blade made of metal. At least a part of a surface of the nose hole to be in contact with a front surface of the driver blade is provided with a protective body.
