摘要： The purpose of the present invention is to provide an actuator such that egress of a lubricant to the outside of a housing during forward and rearward movement of a rod is prevented. The actuator comprises: a housing having a rod through-hole; a rod which passes through the rod through-hole such that a portion thereof protrudes to the outside of the housing and is driven forward and rearward; a first rod sealing member which is arranged near the outside of the housing in the rod through-hole; a second rod sealing member arranged near the inside of the housing in the rod through-hole; a lubricant supply part provided in the housing and supplying lubricant to the rod through-hole; and a pressure change absorption groove which is provided between the first rod sealing member and the second rod sealing member in the rod through-hole to communicate with the lubricant supply part, and forms an air layer while absorbing the pressure changes associated with the forward and rearward movement of the rod.

摘要： An actuator comprises: a housing which is provided with an opening; a slider which is installed so as to be movable relative to the housing; a drive means which is installed in the housing and which moves the slider; at least a pair of seal members which is disposed at the opening of the housing so as to face each other and which exhibits dust-proof and drip-proof functions by engaging with each other; and move-through members which are mounted to both sides of the slider in the movement direction thereof and which move through the pair of seal members. The move-through members each comprise: a move-through section which pushes apart the pair of seal members in the direction in which the pair is separated; a cover section which covers an expanded opening formed between the pair of seal members when the pair is pushed apart by the move-through section; and an opening restriction section which, when the pair of seal members is pushed apart from each other by the move-through section, restricts the amount of opening between the pair of seal members and in turn restricts the size of the expanded opening.
