Reference numeral 23 in the drawings is an actuator for providing a mechanical release force to the fouling member.

On the other hand, when looking at the latching portion accommodated in the interior of the case, as shown in Figure 1b on the right side on the base plate 11, the latch member 21 is rotated counterclockwise on the drawing by the latch spring 21b. It is configured to restrain or release the striker (not shown) fixed to the vehicle body by being elastically installed on the shaft 21a so as to have a tendency, and on the left side thereof, the fouling member 22 elastically engages with the latch member 21. (22a) is provided to control the latching state of the latch member (21). The fouling member 22 is connected to the release lever 24 or the actuator 23 connected to the key set (not shown) to substantially control the latching state of the latch member 21 by the action thereof. .

In this configuration, the pressure protrusion 25 is formed on the upper surface of the latch member 21 so as to press the side surface of the second contact terminal 32b of the lamp switch unit described later. In the drawings, the pressure protrusion 25 protrudes in an annular band shape in which one point 25a is cut off around the shaft hole of the latch member 21, but the position and shape as shown in the overall structure are preferable, but are not necessarily limited thereto. Rather, it protrudes in an arch shape so that the side surface of the second contact terminal 32b of the lamp switch can be pressurized or released according to the latching state on the rotational track of the latch member 21 according to the installation position of the lamp switch unit described later. You may.

Meanwhile, as shown in FIG. 1A or FIG. 1B, a terminal subassembly 31 constituting the lamp switch part is installed downward on the bottom surface of the back plate 13 so as to form a stacked structure on the upper part of the latch member 21. The terminal subassembly 31 is provided with a first contact terminal 32a and a second contact terminal 32b of the lamp switch 32. On the other hand, since the components 31 and 32 of the switch unit are installed on the bottom surface of the back plate 13, they are not shown in FIG. 1A by the back plate 13 and are indicated by dotted lines, as shown in FIG. 1B. In the state where the back plate 13 is removed, it is removed together and is not installed, but is shown to show the structure.
