Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application field] In the present invention, a wire is connected to a throttle lever attached to a rotation shaft of a throttle valve, and the throttle valve is rotated by pulling the wire. The present invention relates to a throttle valve operating device.

[Conventional technology]

Conventionally, a throttle lever is attached to a rotation axis of a throttle valve, a wire end holder is rotatably provided at one end of the throttle lever, a locking hole is provided on a side surface of the wire end holder, and a coaxial direction is provided with the locking hole. A slit groove communicating with the locking hole is provided, a wire is passed through the groove, a wire end of a wire tip is inserted into the locking hole, and the throttle valve is operated by pulling the wire. There is a throttle valve operating device.

[Problems of the prior art]

In the throttle valve operating device, as shown in FIG. 3, a shaft protruding below the wire end holder is rotatably fitted to and attached to the throttle lever. The holder is tilted and pulled, and the rotation of the holder deteriorates. As a result, there is a problem that the holder is worn or damaged (see Japanese Utility Model Laid-Open No. 1-158533). This problem is particularly problematic when the wire end holder is formed of a synthetic resin, and has been a serious problem of resinification.

An object of the present invention is to provide a throttle valve operating device which has good operability and is durable without wear and breakage.

[Means for solving the problem]

According to the present invention, the throttle lever includes an upper lever and a lower lever, and a shaft is formed at the upper and lower ends of the wire end holder, and the shaft is rotatably fitted to the upper lever and the lower lever. It is characterized by having.

[Action]

Since the upper and lower ends of the wire end holder are supported by the upper lever and the lower lever, the holder does not tilt and the operability and durability are improved.

〔Example〕

 Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a side view showing the device of the present invention, and FIG. 2 is a longitudinal sectional view showing a main part of the device of the present invention.

Reference numeral 1 denotes a throttle lever composed of an upper lever 1a and a lower lever 1b. The lever 1 is attached to a rotary shaft 3 of a throttle valve projecting from the carburetor body 2. At one end of the lever 1, a wire end holder 4 is rotatably provided between the upper lever 1a and the lower lever 1b. The wire end holder 4 is provided with a locking hole 6 for the wire end 5 on the side surface, and a groove 7 coaxial with the locking hole 6 and communicating with the locking hole 6. Shaft portions 8 and 9 are formed to be fitted to the upper lever 1a and the lower lever 1b.

Accordingly, since the upper and lower ends of the wire end holder 4 are supported by the upper lever 1a and the lower lever 1b, the holder 4 does not tilt and the operability and durability are improved.

A bracket 11 for fixing one end of the outer wire 10 is attached to the carburetor body 2, and a wire 12 is passed through the outer wire 10 so as to be able to advance and retreat. The wire 12 passes through the groove 7 of the wire end holder 4, and the wire end 5 at the tip thereof is inserted into the locking hole 6. The other end of the wire 12 is connected to a throttle operation lever (not shown).

[Effect of the invention]

As described above in detail, according to the present invention, the shaft is provided at the upper and lower ends of the wire end holder, and the shaft is configured to be supported by the upper lever and the lower lever, so that the holder is pulled when the wire is pulled. The operability is improved without tilting, and the durability is improved.

Further, since the wire end holder can be formed of a synthetic resin according to the configuration of the present invention, the operability can be further improved and the cost can be reduced.

[Brief description of the drawings]

FIG. 1 is a side view showing the device of the present invention, FIG. 2 is a longitudinal sectional view showing the main part of the device of the present invention, and FIG. 3 is a longitudinal sectional view showing the operating state of a conventional throttle valve operating device. . 1a: Upper lever, 1b: Lower lever, 4: Wire end holder, 5: Wire end, 12: Wire.

Claims (2)
