PURPOSE:To make the apparatus light in weight and in a compact size, and reduce noise by forming a push means with a plate parts capable of bending, and by constituting a transferring means which transfers a driving force of a motor reduced a speed thereof to the plate parts by a wire. CONSTITUTION:When the motor 54 starts, as an output axis 59 is fixed to the motor 54 through a clutch plate 53, the rotating speed of the motor 54 is reduced, and said speed is transferred to a rotating body 4, thereby winding a wire 5 round it. By winding the wire 5, a flat spring 3 moves forward within a slit groove 35 and the U-groove 52 through a roller 44, while rotating in a U shape counterclock-wise, thereby moving smoothly forward the push plate. The flat spring is inserted in a space formed between volute springs 11 and 12, whereby the flat spring does not bend over the prescribed allowable range, even if in case of generating back pressure of the sensitive adhesive in a cartridge 1. The flat spring can inject smoothly the adhesive of the cartridge 1 through the nozzle. |
