駆動されるようになつている。The chain guide bar 12 has an endless saw blade chain 1 around it.
6 is supported so that it can run. Chain information bar 1
2 and the endless saw blade chain 16 are similar in construction and operation to those used in conventional chain saws, and these parts are only partially shown schematically for clarity of the drawing. ing. However, the central longitudinal axis II-II of the chain guide bar 12 forms an angle of about 30 ° downwardly from the horizontal central longitudinal axis I-I passing through the centers of the pair of stud bolts 10 and 11 of the body part 1. Since it is formed to extend forward and downward,
The guide bar 12 can be directly attached to a standard chain saw. An endless saw blade chain 16 is engaged with the sprocket 9 and the chain 16 is driven around the chain guide bar 12 by the rotational drive force transmitted to the sprocket 9 via a centrifugal clutch device 8. It is becoming like this.
