Hit tool e.g. electric hammer, hammer drill has stoppage body that detours airflow to pass through inside of main body housing and cool hit mechanism

摘要

Airflow that passes through the inside of a motor housing (3) is generated by a fan (28). An inlet port (27) that allows airflow from the connection portion of a main body housing and the motor housing, is provided behind the main body housing. The airflow is detoured by a stoppage body on the connection portion, to pass through the inside of the main body housing and cool a hit mechanism.
