In a conventionally well-known brush cutter in which a prime mover is attached to the base end of the operating rod and a cutting blade is attached to the tip, as described in Japanese Utility Model Publication No. 53-14594, for example,
A cylindrical grip with a vibration-proof structure is fitted around the outer periphery of a cylindrical operation stick, and a long groove is formed on the outer surface along the length of this grip to insert and hold the throttle cable (wire) of the prime mover. There is something I tried to do. In the above-mentioned conventional brush cutters, especially in the structure of the grip, the cylindrical grip is fitted onto the cylindrical operation stick, which has the disadvantage that the grip tends to move relative to the operation stick. Because the throttle cable was inserted into the long groove to hold it, the diameter of the grip became thicker, making it difficult to grip, and when gripping the throttle cable, the throttle cable hit the hand, resulting in a poor grip, poor feel, and poor operability. Ta.

An embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, reference numeral 1 denotes a hollow operating stick, and an engine 2 is attached to the base end of the operating stick 1, and a cutting blade 4 is attached to the distal end via a gear box 3. A transmission shaft 5 shown in FIGS. 2 to 5 is inserted and supported in the operating rod 1 between the engine 2 and the gearbox 3, so that rotational power from the engine 2 is transmitted to the gearbox 3 and the cutting blade 4. It's summery. A grip 6 is attached to the portion of the operation stick 1 closer to the engine 2, and a loop-shaped handle stick 7 is attached to the side closer to the tip of the grip 6. Lever 8 is attached. Further, a cutting blade cover 9 is attached to a portion of the operation stick 1 near the gear box 3. As shown in detail in FIGS. 3 and 4, the operating rod 1 is formed of a hollow pipe having four concave grooves 10 arranged at equal intervals in the circumferential direction along its length,
Therefore, compared to a conventional operating rod formed of a circular pipe, sufficient strength can be obtained even if the outer diameter is made smaller. As shown in detail in FIGS. 2 to 5, the grip 6 has a cylindrical main body made of elastic rubber, etc., and a hard pipe 11a having a diameter larger than that of the operating stick 1 is integrally fixed to the inner periphery. A thick fitting part with a circular outer periphery, which is provided at both front and rear ends of the grip part 11 and has a protrusion 12 formed on the inner periphery to fit into the groove 10 of the operating rod 1. 13, 13a, and vibration absorbing portions 14, 14 for vibration isolation protruding in an arc shape inside the fitting portions 13, 13a. The grip 6 has fitting parts 13, 13.
The outer periphery of a is tightened with tightening fittings 15, 15a to be fixed to the operation stick 1, and a hanging fitting (not shown) provided on a hanging band worn on the shoulder or waist of the worker is attached to the upper part of the tightening fitting 15. A hanging fitting 16 with a hook hole for fitting is provided integrally. Further, an insertion groove 18 for inserting the throttle wire 17 along the length direction is provided on the inner periphery of the fitting portions 13, 13a, and the throttle wire 17 is inserted into the concave groove of the operating rod 1 from the engine 2. The grip 6 passes along the inside of the grip 6 and is connected to the throttle lever 8. In the brush cutter configured in this way, the grip 6 fits the protrusion 12 into the groove 10 of the operating rod 1 and connects the fitting portions 13, 13a with the fastening fittings 15, 13a.
15a, the grip 6 does not easily rotate in the circumferential direction or move in the length direction. 14, 14 absorb the vibrations of the machine body, so the vibrations transmitted to the hands of the worker are significantly alleviated. Furthermore, even if the grip part 11 is strongly gripped, the throttle wire 17 is placed along the concave groove 10 of the operating rod 1 and inserted through the insertion groove 18 in the fitting parts 13, 13a, so the throttle wire 17 has no influence. The grip 6 has a small outer diameter and is easy to grip, and has good operability. Furthermore, since the operation stick 1 can withstand sufficient strength even if made thinner than the conventional one, it is possible to reduce the weight of the operation stick 1 and to construct a small and lightweight brush cutter as a whole. In the above embodiment, four grooves 10 are provided on the operation stick 1, but it is sufficient to form two or more grooves, and the grooves 10 may be provided at least in the fitting portion of the grip 6. Bye. And grip 6
The number of protrusions 12 of the fitting portions 13, 13a may be at least one.

As explained above, according to the machine body holding structure of the brush cutter of the present invention, a plurality of concave grooves are formed in the longitudinal direction on the operation stick where the grip is attached, and these concave grooves are provided with the inner circumferential surface of the grip (fitting Since the grip is attached by fitting the protrusions formed on the part), the fitting part of the grip does not rotate in the circumferential direction or move in the length direction with respect to the operating stick, resulting in stable operability. is obtained. Also, the throttle wire
Since the inside of the grip is inserted along the concave groove of the control stick, the throttle wire can be held so that it does not get in the way of work, and the grip is thin and easy to grip. Since the information is not transmitted to the user's fingertips, the user's hands do not become sore and operability is improved.
