ACTUATOR
Document Type and Number:
WIPO Patent Application WO/2013/077053
Kind Code:
A1
Abstract:
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.
