FIELD: process engineering.
SUBSTANCE: invention relates to mechanize, primarily hand-held tool comprising case, motor, rpm variator and extending element. Said case houses mechanism chamber filled with lubricant. Motor is arranged inside the case. RPM variator is arranged in mechanism chamber and is coupled with motor for conversion and transmission of rotation produced by motor. Said extending element extends from the case into mechanism chamber in lengthwise direction. Extending element has connection channel with one hole open at extending element front end and another hole open to mechanism chamber external space. At least, one part of extending element wherein connection channel is made is made of resilient material.
EFFECT: prevent oil leaks from mechanism chamber.
