The vehicle charging device according to an embodiment of the present invention will be described in detail below with reference to the drawings. However, this embodiment does not limit the present invention. Furthermore, the components in the following embodiments include those that are easily conceivable by those skilled in the art or that are substantially identical. [Embodiment] An embodiment will be described with reference to Figures 1 to 8. This embodiment relates to a vehicle charging device. Figures 1 and 2 are perspective views of the vehicle charging device according to the embodiment, Figure 3 is a side view of the vehicle charging device according to the embodiment, Figure 4 is a perspective view of the connector according to the embodiment, Figure 5 is a diagram of the vehicle charging device according to the embodiment, Figure 6 is a perspective view of the inlet according to the embodiment, Figure 7 is a cross-sectional view of the inlet according to the embodiment, and Figure 8 is a cross-sectional view of the inlet and connector according to the embodiment. As shown in Figure 1, the vehicle charging device 1 of this embodiment is positioned on the floor 100 of the parking space where the vehicle is parked. The vehicle charging device 1 has a housing 2. The housing 2 is fixed to the floor 100. The housing 2 has a sliding cover 2a and a rotating cover 2b. Covers 2a and 2b cover the device housed in the internal space of the housing 2 from above. As shown in Figure 2, the vehicle charging device 1 has a sliding body 3 located inside the housing 2. The sliding body 3 is a plate-shaped base member and is movable relative to the housing 2 in a first direction L and a second direction W. The first direction L and the second direction W are horizontal directions. If the floor surface of the floor section 100 is inclined, it is preferable that the first direction L and the second direction W are horizontal to the floor surface of the floor section 100. The first direction L corresponds to the longitudinal direction of the vehicle 200 to be charged. The second direction W corresponds to the vehicle width direction of the vehicle 200. The vehicle 200 is positioned to be charged by the vehicle charging device 1 while moving forward or backward along the first direction L. In the illustrated vehicle charging device 1, the first direction L is the longitudinal direction of the housing 2. The second direction W is the short direction of the housing 2 and is perpendicular to the first direction L. The vehicle charging device 1 comprises a sensor 4, a connector 5, a support member 6, a coupling mechanism 7, and an arm 8. The vehicle charging device 1 further comprises a first drive mechanism 10, a second drive mechanism 20, a third drive mechanism 30, and a fourth drive mechanism 40. As shown in Figure 3, connector 5 mates with inlet 210 located on the vehicle 200. Inlet 210 is located at the bottom of the vehicle 200. By mating with inlet 210, connector 5 connects to the vehicle 200's battery. Sensor 4 is used to detect the position of the inlet 210. In this embodiment, sensor 4 is a laser sensor that detects the distance to the reflecting object using laser light. Sensor 4 emits laser light in a predetermined direction and receives the laser light reflected by the object. Sensor 4 is positioned on the slide body 3 and moves with the slide body 3. The sensor 4 illustrated in Figure 2 has a first sensor 4A, a second sensor 4B, and a third sensor 4C. The three sensors 4A, 4B, and 4C are arranged in this order in the second direction W. The second sensor 4B emits laser light upwards in the vertical direction Z. The vertical direction is perpendicular to both the first direction L and the second direction W, and corresponds to the vertical direction of the vehicle 200. The first sensor 4A and the third sensor 4C emit
