COMBUSTION TYPE NAILING MACHINE

摘要

PROBLEM TO BE SOLVED: To provide a combustion type nailing machine provided with a motor support structure easily manufactured and hardly broken. SOLUTION: A motor retaining cylinder 13 storing a motor 18 and made of plastic is supported by a spring 15 provided between a lower part of the retaining cylinder 13 and a cylinder head 11. Acceleration firstly applied to the motor 18 is suppressed to a small degree by slidably providing it in the cylinder head 11 and impact applied to the motor 18 is suppressed by friction between an outer periphery of the retaining cylinder 13 and an inner wall of the cylinder head 11. Further, a combustion gas of high temperature is prevented from directly intruding into the motor 18 by providing a heat-resistant circular disc 14 between the lower part of the motor 18 and the cylinder head 11.
