The invention relates to an electromechanical masturbation device that comprises a main body (1) containing: a power source (2) a motor (3) actuated by the power source (2) a switch (18) for actuating the motor (3) and a shaft (4) that extends inwardly towards the upper end of the main body (1) and is rotated by the motor (3), at one end of which shaft is connected a rotary plate (6) positioned in the vicinity of the upper end of the main body (1) and solidly connected at the centre of the lower face thereof to the shaft (4). The device also comprises: an eccentric shaft (7) connected to the upper face of the plate (6) in a position eccentric with respect to the shaft (4) a flexible connecting rod (8) provided with a first end (9) and a second end (10), which is perpendicularly connected by the first end (9) to the eccentric shaft (7) and is intended to transform the rotary movement of the plate (6) actuated by the shaft (4) into a rectilinear movement a tubular extension (14) which extends from the external face of the upper end of the main body (1) and is disposed perpendicularly to the main body (1), the connecting rod (8) moving longitudinally in the hollow interior thereof. The device further comprises a movable head (13) concentric to the tubular extension (14), which is connected to the second end (10) of the connecting rod (8) and moves longitudinally on the tubular extension (14) by means of the movement transmitted by the connecting rod (8), the movable head in turn comprising: a channel (15) that runs internally along half of the total length of the head (13) from an end thereof, the head being intended to be inserted into the tubular extension (14) and an opening (16) defined by the end of the channel (15) and which is intended to allow the tubular extension (14) to enter channel (15).Dispositivo masturbador electromecánico que comprende un cuerpo base (1), en cuyo interior se alojan una fuente de energía (2), un motor (3) accionado por la fuente de ener
