## Abstract

A rear gate arranged at a rear end of a cargo bed of a truck includes: a support frame arranged at the rear end of the cargo bed and extending along a vehicle width direction; a pair of first and second gate frame bodies arranged at both ends in the vehicle width direction of the support frame; and a first divided gate and a second divided gate supported openably from the first and second gate frame bodies. The rear gate includes a pair of first and second opening/closing switching units configured to switch an opened/closed state of the rear gate. Operation levers of the first and second opening/closing switching units are operated to switch among a vertical opening state, a horizontal opening state, and a locked state restricting from the vertical opening and the horizontal opening.

## Claims

### Claim 1

A cargo bed gate opening-and-closing mechanism of a truck configured to switch between an opened state and a closed state of the cargo bed gate of the truck, the truck including the cargo bed gate openably provided at a rear end of a cargo bed,
wherein the cargo bed gate is surrounded by a support frame member on both sides of the cargo bed gate located in a width direction of the truck and on a lower side of the cargo bed gate, and the cargo bed gate includes two gate members disposed side by side in the width direction, and the cargo bed gate includes a first rod housed inside thereof and extending in the width direction,
wherein the support frame member includes:
a first frame portion configured to support an end of the cargo bed gate in the width direction; and
a second frame portion configured to support a lower portion of the cargo bed gate, and
the first frame portion includes a second rod housed inside thereof, the second rod penetrating the second frame portion in an up-and-down direction of the truck and provided movably in the up-and-down direction toward and away from a main body of the truck, and
wherein the cargo bed gate is configured to open by pivotal movement about an axis extending in the width direction when the first rod is inserted inside the first frame portion, and the second rod retreats from the main body and into the second frame portion, and
the cargo bed gate is configured to enable the two gate members to open respectively by pivotal movement about an axis extending in the up-and-down direction when the first rod retreats from the first frame portion and the second rod moves toward the main body.

### Claim 2 (depends on 1)

The cargo bed gate opening-and-closing mechanism of the truck according to claim 1,
wherein the first rod includes:
a body fixed to the cargo bed gate; and
a movable body provided inside the body and provided movably along an axial direction of the first rod, and
wherein the movable body is pressed by a piston coupled to an operating unit provided in the first frame portion.

### Claim 3 (depends on 2)

The cargo bed gate opening-and-closing mechanism of the truck according to claim 2, wherein the first and second rods are configured to be supported by the operating unit, and
the first rod is configured to perform an advancing-and-retreating operation along the axial direction of the first rod by operating the operating unit,
the second rod is configured to perform an advancing-and-retreating operation along an axial direction of the second rod by operating the operating unit.

### Claim 4 (depends on 1)

The cargo bed gate opening-and-closing mechanism of the truck according to claim 1, wherein each of the two gate members includes the first rod, and the first rod of one of the two gate members is configured to be inserted in the other of the two gate members to restrict the opening of the two gate members.

### Claim 5 (depends on 1)

The cargo bed gate opening-and-closing mechanism of the truck according to claim 1, wherein the first rod is connected with a third rod configured to be movable in the up-and-down direction toward and away from the second frame portion accompanying an advancing and retreating operation of the first rod, and configured to move in a direction opposite to an advancing or retreating direction of the second rod.

### Claim 6 (depends on 5)

The cargo bed gate opening-and-closing mechanism of the truck according to claim 5, wherein the third rod is provided near a center of the cargo bed gate in the width direction.
