Claims (1)

[Claims for Utility Model Registration] 1. A linear motor transport device in which a movable part moves on a fixed part placed substantially horizontally to transport a load, and this transport device further moves the movable part on the fixed part. A pair of constant tension winding spring members are provided at the front and rear ends in the moving direction and have the same rated tension and face each other, and the tip of each leaf spring of these spring members is extended. The parts are connected to the movable part and apply tensions of the same size and opposite direction to the movable part, and each of the leaf springs and the movable part constitute the ceiling of the dust prevention device for the linear motor running path. A dust prevention device for a linear motor running path. 2. The side edges in the transverse direction of the ceiling of the dust prevention device for the linear motor running path, which are configured by each of the above-mentioned leaf springs and the movable part, and the side walls of the dust prevention device are capable of preventing the intrusion of foreign objects from the outside world. A dustproof device for a linear motor running path, characterized in that it is configured to be relatively movable via a seal.
