  • Patent number: 7065863
    Abstract: The present invention has for its object to provide a mechanism for preventing a liquid from splashing from a liquid tank, and a component mounting apparatus with this liquid splashing prevention mechanism. The liquid splash prevention mechanism has a first seal member with a circumferential outer face attached to a first driving lever in a lubricating oil tank, and a second seal member with an arc face set in the lubricating oil tank correspondingly to the first seal member so that a sealing gap for preventing lubricating oil from scattering is formed between the first seal member and the second seal member. Moreover, the lubricating oil is filled in the sealing gap. Scattering of the lubricating oil is more surely prevented by this arrangement. Quality degradation to be caused by adhesion of the lubricating oil to printed boards and the like can be prevented, and productivity can be improved.
