Abstract: A wheel drive unit for a vehicle includes a connecting member separably coupled to a constant velocity joint, a hub housing accommodating the constant velocity joint, and a hub cap to seal the hub housing. In particular, a fixing groove is formed around a first end of the constant velocity joint, and the connecting member is fitted in the fixing groove in a ring shape. When the hub cap is separated from the hub housing, the connecting member can be easily disassembled from the constant velocity joint such that inner components of the wheel drive unit can be easily replaced and repaired.

Abstract: The present invention relates to an antireflection film comprising a hard coating layer in which a ten-point average roughness (Rz) of the surface irregularities is 0.05 ?m to 0.2 ?m and an internal haze is 0.5% to 5%; and a low refractive index layer formed on the hard coating layer, and a display device comprising the antireflection film.

Abstract: A wheel drive unit for a vehicle is provided. The wheel drive unit includes: a connecting member that is separably coupled to a constant velocity joint and fixes a bearing to the constant velocity joint when mounted on the constant velocity joint; a hub housing that can be opened or closed by a hub cap and forms an inner space where the constant velocity joint is disposed and coupled with the hub housing by a bearing. In particular, the hub cap allows the connecting member to be separated from or mounted on the constant velocity joint when the hub cap is separated from the hub housing such that inner components of a wheel drive unit can be easily replaced and repaired.
