The window glass 22 can be moved up and down by the pair of drive rods 18.

Although not shown, the window glass 22
Is in a state of being supported and guided in the opening / closing direction by a guide rail fixed in the door 2.

The motor 10 is provided on a door inner panel (not shown) constituting the door 2 and has a rotating shaft 1 as an output shaft.
The motor 2 can be rotated forward and backward in the motor housing 26. The rotating shaft 12 is rotatably supported by a bearing 34 provided in the motor housing 26.

It is integrally formed with the teeth 3 on a part of the rotary shaft 12.
In the state of being housed in the motor housing 26, the rotary shaft 12 can be normally and reversely rotated by the normal and reverse rotation of the rotary shaft 12.

The pair of guide members 16 are formed integrally with the motor housing 26, and the drive rod 18 is provided.
Is in a curved state to guide the worm 14 so that it can come into contact with the worm 14. Further, the guide member 16 is provided with a pin 28 at a position on the back side of the drive rod 18 at a position where the drive rod 18 comes into contact with the worm 14, and the pin 28 causes the drive rod 1 to move.
By pressing 8 against the worm 14, a reliable contact state between the drive belt 18 and the worm 14 is ensured.

Further, each guide member 16 has a worm 14
The tooth 3 of the worm 14 is placed at the target position sandwiching the
The guide members 16 are inclined in opposite directions along the inclination angle of 2 by a predetermined angle.

Each of the pair of drive rods 18 has a plurality of teeth 30 formed along one side thereof on one side of a flexible rod-shaped member whose both ends are open.
It is formed as a meshing portion that meshes with the teeth 32 of the worm 14.

In this case, the teeth 30 of each drive rod 18 are

Is possible.

The drive belt 18 having the teeth 30 meshing with the teeth 32 of the worm 14 slides while being guided in the guide member 16 by the forward and reverse rotations of the worm 14. The drive belt 18 is adapted to move in an open loop state.

The drive belt 18 includes a round bar-shaped member having teeth 30 formed on one side thereof, a round bar-shaped member having teeth formed over the entire circumference thereof, and a rod-shaped member having a coil-like rod shape on the outer periphery thereof. A member in which a coil-shaped tooth is formed by winding a member can be adopted, and not only a round bar-shaped member but also various square bar-shaped members can be used. For the drive rod 18, it is preferable to use a member having almost no elasticity in the axial direction.

The pair of outer cases 20 slidably guide the drive belt 18 forming an open loop and determine the moving direction of the drive belt 18.
It has a cylindrical shape having an inner diameter substantially corresponding to the outer diameter.

Further, since the outer case 20 determines the moving direction of the drive belt 18, the outer case 20 has such rigidity that it is not easily bent by the sliding movement of the drive belt 18.

Further, each outer case 20 is arranged substantially symmetrically about each guide member 16. Each outer case 20 is composed of a first outer case 20a attached to one end of each guide member 16 and a second outer case 20b attached to the other end.

Each of the first outer cases 20a has a window glass supporting member 24 provided at one end of each guide member 16 and at both ends of the lower side of the window glass 22.
The driving rod 18 pulls the window glass supporting member 24 from the upper side to the lower side, and is connected to the lower end positions of the window glass 22 through the window glass supporting member 24. The window glass 22 is raised and closed, and by pushing the window glass support member 24, the window glass 22 is guided to be lowered and opened.

In this case, since the pair of drive rods 18 are guided by the pair of guide members 16 at symmetrical positions with the worm 14 interposed therebetween, the reaction force when the driving force is transmitted from the worm 14 to the pair of drive rods 18 is opposite. The force is evenly applied to the worm 14, the worm 14 is balanced, and the driving force transmission efficiency is improved.

The movement direction of the pair of drive rods 18 is determined by each outer case 20, and while being guided in each outer case 20, each drive rod 18 slides in the direction of pulling the window glass support member 24. When the window glass 22 moves, the driving force is transmitted by the drive rods 18 to the window glass 22 at both ends of the lower side and the window glass 22 rises and closes.
If you slide it in the direction you press, the window glass 2
2 will descend and open.

In this case, the driving rods 18 can slide the sliding force in the first outer case 20a while being guided and held in the first outer case 20a, and can transmit the sliding force to the window supporting member 24 through the slits 36. Reliable transmission can be performed.

Further, the pair of drive rods 18 transmits the driving force at two places, and further, the driving force is transmitted at both ends of the lower side of the window glass 22, so that the driving force can be efficiently transmitted. .
