Claims

[Scope of utility model registration request]

In an operating lever in which two levers are supported on the same shaft and the operating procedures of these levers are related to each other, the two levers can be rotated around an axis perpendicular to the rotational axis of the lever outside the operating starting point position of the two levers. A locking arm is pivotally supported in the locking arm, and the tip of the locking arm is capable of engaging with the side surface of the lever that is operated later of the two levers, and is attached to the body portion that is operated first. A concave portion is formed to engage with the side surface of the lever on the side, and the hub portion, which is the rotation center of the operating lever on the side that is operated later among the two operating levers, is an end face cam, and the cam surface is operated laterally. The lever has an inclined surface that approaches the direction of the lever that is operated first at the end position of the lever, and a roller that moves parallel to the axis along the cam surface is in contact with the cam surface, and the roller 1. A safety device for an operation lever, characterized in that when the cam surface moves toward the side of the lever that is operated first, the device comes into contact with the side surface of the lever that is operated first.
