Claims

[Scope of utility model registration request]

A second member is rotatably connected to the first member via a coupling pin, an angle detection device is attached to the first member, and the second member is configured to detect the relative swing angle of the second member with respect to the first member. In a lever device that connects a transmission shaft of an angle detection device and a second member via a lever, the hole center of the transmission shaft insertion hole is perpendicular to the transmission shaft insertion hole of the base end boss of the lever. In addition, a pin hole that intersects a part of the transmission shaft insertion hole is drilled on one end surface side of the base end boss, and a tightening bolt hole is drilled on the other end surface side of the base end boss. On the other hand, an inclined pin to be inserted into the pin hole is provided, an inclined surface having an inclined angle with respect to the pin axis is formed on the outer circumference of the inclined pin, and a screw is attached to the inclined pin in the direction of the pin axis. A hole is drilled, and a flat part is formed on a part of the outer periphery of the transmission shaft that is inserted into the base end boss of the lever, and an inclined pin is inserted into the pin hole and the inclined surface of the inclined pin is It is characterized in that it is brought into contact with the flat part of the transmission shaft inserted into the shaft insertion hole, and the tightening bolt is inserted from the other end surface side of the base end boss and screwed into the threaded hole of the inclined pin. lever device.
