## Abstract

An opening and closing body drive device for a vehicle includes a belt frame, plural driven pulleys, a belt wounded around the plural driven pulleys and fixed with a connector with respect to an opening and closing body, a drive unit provided with an output shaft including a rotary axis which extends in a different direction from a rotary axis of each of the plural driven pulleys, and a drive pulley connected to the output shaft of the drive unit. The drive pulley includes a rotary axis extending in the different direction from the rotary axis of each of the plural driven pulleys while extending in the same direction as the rotary axis of the output shaft. The drive pulley is wound with the belt which is twisted between the driven pulleys arranged at opposing sides of the drive pulley in a circumferential direction of the belt.

## Claims

### Claim 1

An opening and closing body drive device for a vehicle opening and closing an opening and closing body of the vehicle, comprising:
a belt frame extending in a moving direction of the opening and closing body;
a plurality of driven pulleys arranged spaced apart from each other in a longitudinal direction of the belt frame;
a belt wounded around the plurality of driven pulleys and fixed with a connector with respect to the opening and closing body;
a drive unit provided with an output shaft including a rotary axis which extends in a different direction from a rotary axis of each of the plurality of driven pulleys; and
a drive pulley connected to the output shaft of the drive unit and configured to drive the belt; wherein
the drive pulley includes a rotary axis extending in the different direction from the rotary axis of each of the plurality of the driven pulleys while extending in the same direction as the rotary axis of the output shaft, and
the drive pulley is wound with the belt which is twisted between the driven pulleys arranged at opposing sides of the drive pulley in a circumferential direction of the belt.

### Claim 2 (depends on 1)

The opening and closing body drive device for the vehicle according to claim 1, further comprising a press pulley including a rotary axis which extends in the same direction as the rotary axis of the drive pulley and pressing the belt against the drive pulley.

### Claim 3 (depends on 2)

The opening and closing body drive device for the vehicle according to claim 2, wherein the press pulley includes a first press pulley and a second press pulley to sandwich the drive pulley therebetween.

### Claim 4 (depends on 2)

The opening and closing body drive device for the vehicle according to claim 2, wherein the drive unit includes a support shaft supporting the press pulley.

### Claim 5 (depends on 1)

The opening and closing body drive device for the vehicle according to claim 1, wherein the opening and closing body drive device for the vehicle opens and closes a sliding door serving as the opening and closing body.
