8 and a cross member 39 is erected at an intermediate portion.

A pair of left and right feed screws 42, 42 driven by a motor 41 are provided. The power of the motor 41 is transmitted to an upper portion of one of the feed screws 42 via a gear mechanism in a gear case 43, and is transmitted to the other feed screw via a power transmission shaft 44 extending in a lateral direction and a gear mechanism in a gear case 45. 42 is transmitted to the upper part.
Nut members 46, 46 are provided to mesh with the left and right feed screws 42, 42, respectively, and coupling arms 47, 47 are coupled to the nut members 46, 46, respectively.

The feed screws 42, 42 are arranged along the guide rails 32, 32. The upper gear boxes 43, 45 are connected to the guide rails 32, 32, respectively. Brackets 48 supporting the lower end portions of the brackets 42 are connected to each other. Also, nut members 46, 4 meshing with the feed screws 42, 42
6, the connecting arms 47, 47 provided on the lifting frame 3
3, 33, respectively. Further, the cross members 35 of the guide rails 32, 32 and the lifting rails 33, 3
Two open stays 49, 49 are laid between the third bulkhead 38 in a cross-shaped arrangement.

The power transmission shaft 44 and the gear case 45
A brake type stopper device 51 is provided at a movable portion between the internal gear mechanism and the internal gear mechanism. This stopper device 51
As shown in FIGS. 5 to 8, is formed on a split shaft 54 provided between the gears 52 and 53 mechanisms in the gear case 45 and the power transmission shaft 44, and 55 is a gear case cover,
56 is a mounting bracket, 57 is a casing, 58 is a stopper disk, 61 is a housing, 65 is a coil spring, 66 is a lever holder, 67 is a pivot pin, 68
Is a release lever. That is, a stopper disk 58 is spline-fitted on a split shaft 54 connected to the power transmission shaft 44 with a gear 53 that meshes with a gear 52 above the feed screw 42. Projections 59 are formed.

The housing 61 accommodated in the casing 57 so as to be non-rotatably and axially movable by chamfered portions 57a and 61a formed in parallel with each other has a plurality of grooves 63 in a disk portion 62 facing the stopper disk 58.
And a coil spring 65 is disposed between the disk portion 62 and the casing 57 so as to be loosely fitted on the split shaft 54.
Has been disguised. Further, a lever holder 66 is provided adjacent to the casing 57, and a release lever 68 is assembled to the holder 66 via a pivot pin 67. The release lever 68 is linked with the trunk lock device 26. Cable 27 is connected. The other end of the release lever 68 is a forked portion 69 that engages with the small diameter portion 64 of the housing 61.

According to the trunk lid elevating device 31 having the above configuration, the left and right feed screws 42, 42 are rotated synchronously by the driving of the motor 41, and the feed screws 42, 42 are rotated.
The coupling arms 4 are connected to the nut members 46, 46 respectively meshing with each other.
Left and right elevating rails 33, 33 connected via 7, 47
Is slid along the guide rails 32 via the bearing assemblies 37, 37, so that the trunk lid 21 fixed to the lifting frames 33, 33 is raised and lowered. When the rear end of the trunk lid 21 is locked by the trunk lock device 26 in the lowered position of the trunk lid 21, the tension of the interlocking cable 27 of the trunk lock device 26 is released,
The housing 61 is pushed toward the stopper disk 58 by the coil spring 65 compressed between the casing 57 of the stopper device 51 and the protrusion 63 of the stopper disk 58 in the groove 63 of the disk portion 62 of the housing 61.
Are pressed against each other, and the rotation of the split shaft 54 is prevented by the frictional force.

As described above, in the closed state of the trunk room 3 in which the trunk lid 21 is lowered, in addition to the locked state with the vehicle body 1 by the trunk lock device 26 at the rear end side of the trunk lid 21, the trunk lid elevating device 3
The split shaft 54 provided on the vehicle body 1 cannot be rotated by the stopper device 51, and the front end side of the trunk lid 21 supported by the vehicle body 1 via the elevating device 31 is also locked to the vehicle body 1. Therefore, it is possible to prevent the front portion of the trunk lid 21 from fluttering due to vibration, wind pressure, and the like during traveling.

When the trunk lock device 26 is released to open the trunk, the bifurcated portion 69 of the release lever 68 is pulled by the pulling action of the interlocking cable 27 to the small diameter portion 64.
Then, the housing 61 is moved in a direction away from the stopper disk 58 via, and the rotation restraining force of the divided shaft is released. Therefore, the raising / lowering operation of the trunk lid 21 is performed without any trouble. Here, in FIG. 3, reference numeral 71 denotes an elevating / lowering state detection sensor, and reference numeral 72 denotes an emergency cable.

The specific detailed structure and the like can be appropriately changed in addition to the embodiment. For example, the stopper device may be a friction brake type using rubber or the like.
