Abstract
In a seamless capsule manufacturing apparatus that ejects a droplet from a nozzle into hardening liquid to manufacture a seamless capsule SC, tube passages which are synthetic resin tubes are provided as flexible sections between pumps and the nozzle. The vibration caused by the pumps is absorbed in the flexible sections and thus is not transmitted to the nozzle, whereby eyes or the like of the seamless capsule caused by vibration noises can be suppressed. Instead of a synthetic resin tube, a vibration absorbing block formed of an elastic member may be attached to the tube passages. Alternatively, a vibration absorbing unit, which is provided with a pad formed of an elastic member and for holding the tube passages, may be provided.
