The former and the latter known examples both have a problem in the structure for imparting initial tension to the wire cable. The initial tension is a pressure for removing the slack of the arranged wire cable regardless of the tension spring. In the former known example, the initial tension is applied to the wire cable laid between the wire drum and the sliding door by rotating the adjusting mechanism using a tool such as a screwdriver to adjust the interval between the tension rollers. Therefore, the work of applying the initial tension is unrelated to the mounting of the power slide device itself, and the work is also troublesome. Also, the latter known example has a similar problem because the initial tension is adjusted by rotating the adjusting mechanism using a tool such as a screwdriver in a similar manner.
