Power tool having lubricant leakage preventing structure
摘要:
A power tool suppressing expansion of the air in a chamber and preventing lubricant encapsulated in the chamber from being leaked outside of the chamber. A communication portion communicates a speed reduction chamber with a motor housing communicating with an atmosphere. A communication passage forming component made from an elastic material is fittingly inserted into the communication portion which forms a communication passage including a plurality of impediment portions. When the air containing lubrication component is passed through the communication passage, the air collides against the impediment portions, allowing grease component to be adhered to the impediment portions.
