A method of preventing a lubricant of a gear unit from splashing, comprising:

• gear means for transfer rotation inputted from an external source to at least one driven member;
• casing means for enclosing the gear means and for containing a lubricant to lubricate the gear means, with the casing means having at least one output shaft opening;
• and
• lubricant conveying means for conveying lubricant between the output shaft opening and a lubricant discharge outlet provided in a bottom portion of the casing means.

A method of preventing a lubricant of a gear unit from splashing, comprising:

• providing at least one gear for transfer rotation inputted from an external source to at least one driven member;
• enclosing the gear in a unit case that defines an interior space for containing a lubricant to lubricate the gear;
• providing at least one output shaft opening in the unit case for connecting the driven member to the gear;
• and
• providing a lubricant passage with an inlet provided adjacent the output shaft opening and a lubricant discharge outlet provided in a bottom portion of the unit case to communicate lubricant between the output shaft opening and the lubricant discharge outlet.
