Deflection movement transmission device, endoscope bending controller and endoscope

A deflection movement transmission device comprising:

• a base element having a head portion,
• a control element for effecting a deflection movement, the control element having a pivot portion that is supported on the head portion of the base element and is pivotable relative to the head portion of the base element for effecting a deflection movement,
• at least one movement transmission wire body that is connected to the pivot portion of the control element,
• an elongate transmission guiding body having a distal connector and a distal end, wherein the movement transmission wire body is guided along the elongate transmission guiding body,
• a bendable body to be deflected that is seated at the distal end of the transmission guiding body, opposite to the control element, and to which the movement transmission wire body is mounted in a manner spaced apart from the connector to the transmission guiding body,
• the control element being configured as an actuating lever which, at the pivot portion, has a foot surface facing the base body,
• the head portion of the base element having a front face facing the control element,
• the foot surface of the pivot portion of the control element and the front face of the head portion of the base element being respectively curved towards each other so that the foot surface and the front face can be rolled on each other,
• the pivot portion of the control element having an articulation point of the movement transmission wire body at its outer side.
