Embodiment Construction

[0018]Hereinafter, preferred embodiments of the present invention will now be described in detail with reference to the attached drawings.

[0019]A significant factor of the engine oil leakage is the existence of a screw thread in a drain cock, and damage to it as a drain hole 13 and the drain cock of an engine oil pan 10 are opened and closed when exchanging engine oil. Accordingly, embodiments of the present invention reduce the possibility of such problem by providing a drain hole 13 of the engine oil pan 10 connected to the drain cock without the screw thread.

[0020]The drain cock in accordance with the present invention comprises a receptacle 11 for exchanging engine oil attached on the bottom of the engine oil pan 10 and an insertion 12 for exchanging engine oil inserted into the receptacle 11 in a sliding, drawer-like fitting. The receptacle 11 for exchanging engine oil attached on the bottom of the engine oil pan 10 includes a predetermined volume space for accommodating the in...
