An embodiment is a vehicle door opening and closing apparatus. The vehicle door opening and closing apparatus including a vehicle door, a rail mounted on a vehicle body, a roller unit mounted on the vehicle door, the roller unit configured to move along the rail and allow the vehicle door to open and close in a mode selected from a swing mode and a sliding mode, and a hold lock mounted on the vehicle body, the hold lock including a passing rod configured to releasably hold the roller unit in a predetermined position.

Vehicle door opening and closing apparatus

In the present disclosure, a seatback pocket is introduced, which includes a backboard combined with a rear side of a seatback and including a hinge shaft provided at a lower end in left and right width directions; a pocket member having a hinge part formed at a lower end and combined with the hinge shaft through a hinge structure to be rotated based on the hinge shaft to provide a pocket space in a region facing the backboard; and an elastic member connected between both ends of the pocket member and the backboard in a shape blocking sides of the pocket space, and configured to provide an elastic restoring force with respect to a rotation direction of the pocket member.

Seatback pocket

A transmission system of a hybrid electric vehicle may include a first shaft connected to an engine, a first hollow shaft disposed without rotational interference with the first shaft and provided with a first output gear, a second hollow shaft disposed without rotational interference with the first hollow shaft and provided with a second output gear, a second shaft disposed in parallel with the first shaft and operably connected to the first shaft and the first hollow shaft through a gear unit so as to selectively transmit torque of the first shaft to the first hollow shaft, a clutch selectively connecting the second shaft to the first hollow shaft, a first motor/generator operably connected to the second hollow shaft, and a second motor/generator operably connected to the second shaft.

The present invention provides an exhaust heat recovery device configured to perform heat exchange between three media such as, exhaust gas, coolant, and oil. According to preferred embodiments of the present invention, the exhaust heat recovery device is configured such that the heat of exhaust gas discharged from an engine is transmitted to the coolant and the oil at the same time and direct heat exchange between the coolant and the oil is made, thereby simultaneously increasing the temperature of the coolant and the oil during the initial start-up of the engine (fast warm-up). As a result, it is possible to reduce friction loss of powertrain, thereby improving fuel efficiency. Accordingly, an object of the present invention is to provide an exhaust heat recovery device which is configured to perform the integral heat exchange between the exhaust gas, the coolant, and the oil.
