Abstract: The invention provides a tensioner initial position setting device for a tensioner having a housing, a plunger slidably mounted within the housing, and shoes mounted opposite the bottom of the plunger and the top of the housing, wherein it further including concave grooves or penetration holes formed on both lateral sides of each shoe, and a set wire inserted into said concave grooves or holes with both ends of said set wire tied together, thereby preventing the plunger from projecting. The tensioner initial position setting device can easily release an initial position of a tensioner mounted in a limited space in a state in which an initial position is set so as to prevent the plunger from projecting.
