Abstract: An article transport feeder is equipped with an article transporter removably attachable to a vibratory head of a vibration mechanism. The article transport feeder is also equipped with a fastening unit having an operation lever. The fastening unit rotates the operation lever to retainably engage the article transporter with the vibratory head by fastening. The article transport feeder is further equipped with a movable coupling member having a spindle elastically deformable. The movable coupling member is coupleable to the fastening unit and allowed to move along with the rotation of the operation lever. The spindle is elastically deformable by moving the movable coupling member along with the rotation of the operation lever of the fastening unit to elastically retain the engagement of the article transporter with the vibratory head.

Abstract: A sealing structure is provided that includes a sealing member having an annular shape and elastically deformable. The sealing member is interposed between a top plate of a cabinet mounted with a vibrator and a vibrating head of the vibrator disposed in a manner that protrudes upward out of an opening of the top plate. The sealing member includes an upper coupler, an intermediate coupler continuous to the upper coupler, and a lower coupler continuous to the intermediate coupler. The upper coupler is couplable to an upper part of the vibrating head, the intermediate coupler is couplable to the top plate, and the lower coupler is couplable to a lower part of the vibrating head.
