A shade device (1) is provided with a connection stop mechanism (65) whereby one end (61) of a chain (63) that is made to travel by a travel mechanism (64) is elastically stopped from traveling downward beyond a predetermined position. A pin (102) having a large head (101) is formed in a travel member (91) of the connection stop mechanism (65). An elongated hole (125) fitted over the pin (102) is formed in a rotating arm member (95) of the connection stop mechanism (65) in order that the rotating member (95) will be connected to the travel member (91) rotatably and rectilinearly movably. A large hole (127) into or from which the large head (101) of the pin (102) can be inserted or removed, respectively, is formed in that end (126) of the elongated hole (125) which is located near a second end (94) of the rotating arm member (95).
