Abstract
An apparatus which can easily and reliably prevent leakage of lubricant is provided. The apparatus comprises a casing storing the lubricant at the inside and formed with a hole, a jig which can be taken out from and inserted into the inside of the casing through the hole, and a communication part provided at the jig or at the casing separate from the hole and communicating the inside of the casing with the outside. An amount of outside air corresponding to the volume which the part of the jig occupied at the inside of the casing is introduced to the inside of the casing through the communication part when that part of the jig is pulled out from the inside of the casing.
