         8 . The squeegee device according to  claim 6 , wherein:
 the second biasing member includes a coil spring;   the squeegee has a rod, which has a small diameter part onto which the second biasing member is fitted, and a large diameter part, which is disposed lower than the small diameter part;   a lower end of the second biasing member contacts a support surface at a boundary between a lower end of the small diameter part and an upper end of the large diameter part; and   an upper end of the second biasing member contacts the holder.   
     
     
         9 . The squeegee device according to  claim 1 , wherein:
 the engaging part has a first hook shape; and   the engaged part has a second hook shape that is engageable with the first hook shape in an interference fit manner.   
     
     
         10 . The squeegee device according to  claim 9 , wherein a plurality of each of the engaging parts and the engaged parts are arranged in the left-right direction. 
     
     
         11 . The squeegee device according to  claim 10 , wherein:
 a suction flow path is defined through the body; and   the engaging parts and the engaged parts are respectively disposed on opposite sides, in the left-right direction, of the suction flow path.   
     
     
         12 . The squeegee device according to  claim 1 , wherein the manipulatable part protrudes upward from an upper surface of the holder. 
     
     
         13 . The squeegee device according to  claim 12 , wherein the holder has a guide opening configured to guide the manipulatable part in a front-rear direction. 
     
     
         14 . The squeegee device according to  claim 12 , wherein:
 two engaging parts are disposed in the left-right direction; and   the manipulatable part is disposed between the two engaging parts in the left-right direction.   
     
     
         15 . The squeegee device according to  claim 1 , further comprising:
 a first biasing member, which biases the movable member in a first direction that causes the engaging part to engage with the engaged part; and   a second biasing member, which biases the squeegee in a second direction that causes the squeegee to separate from the holder;   wherein movement of the squeegee toward the holder against the biasing force of the second biasing member causes the engaging part to engage with the engaged part and thereby detachably fasten the squeegee to the holder.   
     
     
         16 . The squeegee device according to  claim 1 , further comprising:
