2. Description of the Related Art Generally, a general-purpose engine is provided with a governor in order to keep the rotation speed constant even when the load fluctuates. When the engine speed rises above the set speed, the governor drives the throttle valve in the closing direction to suppress the engine speed to the set speed, and conversely,
When the engine speed falls below the set speed, the engine speed is increased to the set speed. In this case, the set number of revolutions of the engine is set by operating the accelerator lever, and the amount of operation of the accelerator lever is controlled by a release wire formed so that the inner wire and the outer wire can slide with each other. Informed to the governor. Since the release wire is routed around the engine and wired, the release wire is supported on the engine by a wire holder.

A structure described in Japanese Utility Model Laid-Open No. 57-134334 is known as a conventional wire holder of this type. For this, the basis is described 11 Figures 9. FIG. 9 is a side view of a general-purpose engine, and 1 indicates an engine body. The governor provided in the engine body 1 is configured such that a thrust is applied to the governor sleeve 10 by a detection member (not shown) which operates as necessary for the rotation of the crankshaft 30. Rises, the tension of the governor spring 9 is overcome, and the thrust of the governor sleeve 10 acts to tilt the governor fork 11 to the left and right, thereby rotating the governor lever 12 counterclockwise. Governor lever 12
Rotation drives the throttle valve 15 in the closing direction via the rod 13 and the throttle lever 14, thereby reducing the engine speed to the set speed. Conversely, if the engine speed drops below the set speed, the governor spring 9
Rotates the governor lever 12 clockwise to increase the engine speed to the set speed.

The set number of rotations can be set within a certain range by operating a speed control lever 3 pivotally supported on a support plate 2 fixed to the engine body 1 to change the tension of a governor spring 9. Can change freely within. The speed control lever 3 is connected to an accelerator lever 4 for remote operation via an inner wire 5 a of a release wire 5.
The outer wire 5b of the release wire 5 is supported by a wire holder 6, and the wire holder 6 is formed integrally with or fixed to the support plate 2. In the case of the wire holder 6 formed integrally with the support plate 2, FIGS .
As shown in FIG. 1 , the front end of the support plate 2 is bent into a U-shape to form a wire holder main body 60.
A notch groove 6a through which the inner wire 5a can be inserted is provided in the midway wall 61, and a large-diameter hole 6b is formed in the bent piece 62 on the distal end side. The large-diameter hole 6b has a size sufficient for the outer wire 5b to pass therethrough. Folded piece 63 at the back
Is formed with a small-diameter hole 6c, through which only the inner wire 5a can penetrate.
b cannot be inserted. The large-diameter hole 6b and the small-diameter hole 6c are continuous with the notch groove 6a. Therefore, the portion of the inner wire 5a is passed through the notch groove 6, the outer wire 5b is passed through the large-diameter hole 6b, and the distal end is located at the back. The inner wire 5a can be led out from the small-diameter hole 6c by making contact with the bent piece 63 of the portion. As shown in FIG. 9 , the tip of the inner wire 5a is locked to the connecting member 16 of the speed control lever 3.

[0005] A reinforcing member 7 is interposed between the wire holder 6 and the support plate 2. The reinforcing member 7 is bent in a substantially V-shape. The bent portion 7a on the front side is spot-welded by contacting the bent portion 63 at the back of the wire holder 6, and the flat plate at the other end is passed through the inclined support portion 7b. The fixing portion 7c is spot-welded in contact with the flat portion of the support plate 2. The front bent portion 7a and the inclined support portion 7b are formed with through holes 7d and 7e through which the inner wire 5b is inserted. Also, a protruding piece 7 extending forward is provided on the front bent portion 7a of the reinforcing member 7.
f is provided, and the protruding piece 7f penetrates through the inner bent piece 63 of the wire holder 6 and is locked to the wire holder 6.

In FIG . 9 , reference numerals 17 and 18 denote stoppers formed on the speed control lever 3, which contact the adjusting screws 19 and 20 screwed to the support plate 2 to regulate the rotation angle of the speed control lever 3. . By adjusting these adjusting screws 19 and 20, the rotation angle of the speed control lever 3 can be variably adjusted.

[0007]

[Problems to be Solved by the Invention] By the way, FIG.
The wire holder 6 having the conventional structure shown in FIG. 11 is constructed such that the outer wire 5b of the release wire 5 is inserted into the large-diameter hole 6b, and the tip of the outer wire 5b contacts the bent piece 63 at the back of the wire holder 6. 5 is supported. However, in the case of such a structure, the large-diameter hole 6b is formed to be larger than the diameter of the outer wire 5b in order to facilitate the insertion operation, so that the release wire 5 vibrates in the wire holder 6 due to engine vibration or the like. For this reason, the outer wire 5b may rub against the large-diameter hole 6b, and the outer wire 5b may be damaged.

Therefore, the notch groove 6a of the wire holder 6 is crimped with a tool such as pliers to narrow the notch groove 6a, thereby reducing the diameter of the large-diameter hole 6b.
It is conceivable that the outer wire 5b is clamped by the above.
However, when the outer wire 5b is clamped by the wire holder 6, a problem occurs that the outer wire 5b cannot be easily removed.

[0009] The present invention has been made based on such circumstances, it is an object without release wire uniquely vibration, and can easily be removed, moreover, the operation of the release wire Don't hurt
It is intended to provide a wire holder for a small engine.

[0010]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below based on a first embodiment shown in FIGS.

This embodiment shows an example in which the invention is applied to the governor shown in FIG. 9 , but the governor and other structures may be the same as those in FIG. explain. FIG. 1 is a perspective view showing a state where the release wire 5 is mounted on the wire holder 40, FIG. 2 is an exploded perspective view thereof, FIG. 3 is a sectional view showing the mounted state, and FIG.
FIG.

The holder body 100 of the wire holder 40 is
By bending the plate material, opposing bent pieces 41 and 44 and these
Are formed in a U-shape from a bent wall 46 that integrally connects
A large diameter hole 42 is formed in the bent piece 41 on the tip side. The large-diameter hole 42 has a size sufficient to insert the outer wire 5b. Inside the large-diameter hole 42, a support piece 43 is formed integrally with the inner surface by cutting and raising the support piece 43, and the support piece 43 is folded inside the wire holder 40. A small-diameter hole 45 is formed in the bent piece 44 at the back facing the bent piece 41, and only the inner wire 5a can pass through the small-diameter hole 45, and the outer wire 5b cannot be inserted. . A screw hole 47 is formed in the bent wall 46 between the two bent pieces 41 and 44, and a holding screw 48 is screwed into the screw hole 47. Reference numeral 49 denotes a flange for attachment, which is integrally formed with the support plate 2 in FIG. 9 or fixed to the support plate 2.

In the case of such a configuration, the release wire 5
The exposed inner wire 5a is inserted into the large-diameter hole 42 formed in the bent piece 41 on the distal end side of the wire holder 40, and is led out from the small-diameter hole 45 formed in the bent portion 44 at the back, and the inner wire 5a is derived. The distal end is locked to the connecting member 16 of the speed control lever 3 shown in FIG . At this time, the outer wire 5b of the release wire 5 is connected to the large-diameter hole 4 of the wire holder 40.
2 and cannot be inserted through the small-diameter hole 45 formed in the bent portion 44 at the back, so that it contacts the bent piece 44 at the back. In addition, the outer wire 5b comes along with a support piece 43 extending inward from the bent piece 41. In this state, a holding screw 48 is screwed into a screw hole 47 formed in the bent wall 46 on the way, and the side surface of the outer wire 5b is pressed by the holding screw 48. Then, the outer wire 5b is pressed.
And is fixed to the wire holder 40 by the
And the part where the presser screw 48 contacts is localized.
Is supported by the support piece 43 so as not to be deformed.

According to such a configuration, since the outer wire 5b is sandwiched between the holding screw 48 and the support piece 43, when the wire holder 40 vibrates, the release wire 5 also vibrates integrally. Therefore, the outer wire 5b does not rub against the inner surface of the large-diameter hole 42, and wear is prevented. In addition, the release wire 5 is
Locally deformed according to the tip of the cap screw 48 on the side
Because there is no vibration, the vibration resistance of the inner wire 5a increases.
And smooth movement of the inner wire 5a
And the release wire 5 is thus locally
The supporting piece 43 for preventing the bending
Because it was cut and raised from the bent piece 41 of the main body 100,
The structure is simple. Further, when the holding screw 48 is loosened, the holding of the outer wire 5b is released, so if the release wire 5 is pulled out in the direction of the large-diameter hole 42, the wire holder 4
0 can be removed. Therefore, the release wire 5 can be easily removed.

FIGS. 5 to 8 show a second embodiment of the present invention. The second embodiment is different from the first embodiment in that a cutout groove 50 is formed in a halfway bent wall 46. The notch groove 50 communicates with the large-diameter hole 42 and the small-diameter hole 45, and has a width that allows the inner wire 5a to be inserted.

In the case of the second embodiment as well, the same operation and effect as those of the first embodiment are obtained, and the notch groove 50 is formed.
Can be inserted into and removed from the wire holder 40, and the large-diameter hole 42
Further, since there is no need to insert the release wire 5 in the axial direction of the small-diameter hole 45, the work of attaching and detaching the release wire 5 is further facilitated.
