2. Description of the Related Art In vehicles such as bicycles, a lever-type brake operating device is mounted on a handlebar for operating a brake device. The brake operating device has a bracket attached to the handlebar and a brake lever attached to the bracket so as to be swingable. The brake lever is connected to a brake cable or a hydraulic piston as a connecting body for connecting to the brake device, and the swing of the lever member moves the brake cable and the viston to operate the brake device.

In this type of brake operating device, an output / input ratio (lever ratio) determined by an input stroke by operating a brake lever and an output stroke for operating a connecting body can be changed. -3957
It is disclosed in Japanese Patent No. This brake operating device

The cable connector is connected to the brake lever via an adjustment mechanism that can adjust the output / input ratio and the brake release position of the brake lever. The adjusting mechanism is rotatably attached to, for example, a cable connector and eccentrically connected to the brake lever. The distance to the connection position of the cable connector is changed.

If the output / input ratio can be changed in this way, the weight at the time of operating the brake lever changes. That is, the degree of change in the braking force can be changed for the same lever stroke. Therefore, the relationship between the lever stroke and the braking force can be changed according to the rider's taste, skill, race condition, and the like.

SUMMARY OF THE INVENTION In the above conventional configuration,
When changing the output / input ratio, the adjustment mechanism attached to the cable connector in the state of being connected to the connecting body must be adjusted, and therefore it must be adjusted using a tool or the like. Therefore, it is difficult to change the input / output ratio during traveling. Therefore, for example, even if the weather suddenly changes during the race and the output / input ratio needs to be changed, it cannot be dealt with.

An object of the present invention is to provide a vehicle brake operating device capable of changing the output / input ratio so that the output / input ratio can be changed during traveling.

When the output shaft moves in the axial direction, the second gear meshes with one of the first gears to rotate the output shaft. When the output shaft rotates, the operating mechanism operates the connecting body. Here, the rotation of the swing shaft is transmitted to the output shaft at a different gear ratio according to the number of teeth of the first and second gears, and the output shaft rotates. As a result, the operating mechanism operates in different amounts with respect to the swing amount of the brake lever. Therefore, the output / input ratio can be easily changed only by moving the output shaft and changing the meshing between the first gear and the second gear.
