That is, the path | route through which the electric cable 41 passes through the storage space 14 (the housing of the power supply unit 2) is restrict | limited by the stationary metal member 22. As shown in FIG.

In the present embodiment, the restricting portion (fixed metal member 22) is disposed between the cover (cover body 20) and the electric cable 41. That is, the electric cable 41 is arrange | positioned between the restricting part (fixed metal member 22) and the inner surface of the storage space 14 (in this embodiment, inner surface of the housing of the power supply unit 2). Therefore, when the power cable 41 is pulled, the power cable 41 touches the restricting portion (fixed metal member 22), so that deformation of the power cable 41 is suppressed. In particular, in the present embodiment, even if the power cable 41 is deformed, the restricting portion (fixed metal member 22) is disposed so that the bending radius of the electric cable 41 does not exceed the allowable bending radius.

One end of the electric cable 41 is connected to the connection terminal table 201 of the CCID 200 via the L-shaped pipe 21. Moreover, this piping 21 is arrange | positioned between 2 A of step parts and the cover body 20 which are provided in the form which protrudes downward in the back of the inside of the housing of the power supply unit 2. As shown in FIG.

As shown in FIG. 25, each fixed metal member 22 is formed by bending a metal plate and includes a U-shaped main body 22A as viewed in a plane in which an electric cable 41 is wound around its outer circumference. At the lower edge (the upper edge in FIG. 25) of the main body 22A, a flat extension piece 22B protruding in the rearward direction is provided. In addition, a pair of flat plate-shaped mounting pieces 22C protruding in a direction closer to each other are provided at the upper edge (the lower edge in FIG. 25) of the main body 22A.
