Abstract: To provide an electric pipette in which the impact resistance against the dropping of the electric pipette is elevated, the external breakage of the device and the damage of operation performances are reduced, and the discharging performance of the device is maintained and ensured. An electric pipette 100 including a main casing 1, an operation switch 14, a hand grip 15, a display-operation section 9, a release switch 12 and a finger rest 16, in which at least one shock absorber 201 to 206 disposed on at least one apex of at least one line among a line LF, a line LB, a line LL, a line LR and a line LU, which are prepared by drawing lines between two or more projecting sites in each of a front surface 100F, a back surface 100B, a left side surface 100L, a right side surface 100R and an upper surface 100U.

Abstract: Provided is an overload prevention mechanism including a load receiving part provided with a flange having at least three ribs on the upper surface of the flange; a pedestal located below the load receiving part; an elastic body which has one end in contact with the load receiving part and the other end in contact with the pedestal, and which biases the load receiving part and the pedestal in such a direction that the load receiving part and the pedestal are separated from each other; and a connection member having on the lower surface thereof recessed grooves which engage with the ribs. The three or more ribs are disposed so as to restrict inclination and rattling of the load receiving part due to a load applied to the load receiving part.
