1. An electromechanical actuator for a shading device, the electromechanical actuator comprising at least:
a casing,
a torque support, the torque support being arranged at a first end of the casing,
a ring, the ring being inserted at least partly around the torque support, the ring forming a bearing guiding the rotation of a winding tube of a motorized driving device of the shading device, around the casing of the electromechanical actuator,
an electrical power supply cable, the electrical power supply cable being configured to be connected to an electrical power supply network, the electrical power supply cable comprising either at least one shielding or at least one earth electrical conductor,
an electric motor, the electric motor being mounted within the casing, the electric motor being supplied with electrical energy via the electrical power supply cable, and
a device for discharging electrostatic charge, the device for discharging electrostatic charge comprising at least one electrical conduction element, the electrical conduction element being configured to be in electrical contact with the winding tube,
wherein
the ring bears the electrical conduction element of the device for discharging electrostatic charge,
the device for discharging electrostatic charge further comprises at least one electrical linking element,
the torque support at least partly accommodates the electrical linking element,
in that the electrical conduction element, arranged at the ring, is configured to be in electrical contact with the electrical linking element, arranged at least partly at the torque support,
and in that the electrical linking element electrically connects the electrical conduction element to the shielding of the electrical power supply cable or to the earth electrical conductor of the electrical power supply cable.
