1. A latch structure for attachably and detachably holding a connector in a cage, the connector comprising a connector body having an almost rectangular parallelepiped shape and an insertion part formed on a front end surface of the connector body so as to be inserted in the cage, and the cage having an engagement hole, the connector body having an upper surface, a lower surface opposing the upper surface and opposite side surfaces extending from the upper surface to the lower surface, the latch structure comprising: a latch cover rockably installed on the upper surface of the connector body, being formed of a single plate material and having a cover body for covering the upper surface of the connector body;an engagement claw formed at an end portion of the latch cover and located over the front end surface of the connector body so as to engage with the engagement hole of the cage;a spring member for always energizing the latch cover so that the engagement claw engages with the engagement hole;rocking members formed on either side of the cover body of the latch cover and formed by bending the plate material downward, the rocking members being located between the engagement claw and a rear portion of the cover body along a longitudinal direction of the connector;rocking grooves formed in the opposite side surfaces of the connector body for rockably engaging with the rocking members, wherein each of the rocking members is fitted to each rocking groove such that the latch cover is rockably installed on the connector body; anda rocking restriction part for restricting the rocking of the latch cover at a position when the cover body is horizontally oriented, the rocking restriction part being formed at an end portion of the upper surface of the connector body,wherein an inclined region of the upper surface of the connector body is formed to be diagonally inclined so as to be lowered in height toward a rear end portion of the connector body, the inclined region extends from the rocking grooves to the rear end portion of the connector body,wherein a distance between the upper surface and the lower surface at the rear end portion of the connector body is less than a distance between the upper surface and the lower surface at the rocking grooves, andwherein the latch cover and the connector body have a substantially rectangular parallelepiped shape as a whole when the engagement claw engages with the engagement hole. 2. The latch structure according to claim 1, wherein the spring member is integrally formed with the cover body and formed of a plate spring energizing upward the rear portion of the cover body, the rear portion of the cover body being located behind the rocking members. 3. The latch structure according to claim 1, wherein each rocking member is formed of a circular plate axis to become a rocking axis of the latch cover and a supporting leg connecting the circular plate axis and the latch body, and each rocking groove is formed of an axis groove for rotatably housing the circular plate axis and a groove for rotatably housing the supporting leg, and the circular plate axis is housed in the axis groove and the supporting leg is housed in the groove so that the latch cover is rockably installed on the connector body. 4. A cable assembly comprising: the connector comprising the latch structure is connected to according to claim 1; anda cable connected to the connector. 5. The latch structure according to claim 1, wherein the rocking members are located behind the engagement claw. 6. The latch structure according to claim 1, wherein the engagement claw comprises a protrusion protruding downwardly. 7. The latch structure according to claim 2, wherein the spring member maintains a downward force at the engagement claw. 8. The latch structure according to claim 1, wherein the latch cover comprises the cover body provided over the upper surface of the connector body and each of the rocking members extending toward a respective one of the opposite side surfaces of the connector body. 9. The latch structure according to claim 1, wherein the rear portion of the cover body is configured to be pressed downward for attaching and detaching the connector from the cage. 10. The latch structure according to claim 1, wherein, when the engagement claw is engaged with the engagement hole, a gap between the upper surface and the latch cover is greater at the rear end portion of the connector body than a gap between the upper surface and the latch cover at a front end portion of the connector body.
