Abstract:
1. A substrate processing apparatus, comprising: a brush for cleaning a substrate; a seesaw member which is swingable with a support member serving as a fulcrum, the seesaw member having a force point section at one side with respect to the fulcrum and an actuating point section at other side with respect to the fulcrum; a pushing actuator arranged to give a driving force to the force point section of the seesaw member, thereby to swing the seesaw member around the fulcrum, thus giving, to the seesaw member, a pushing force for pushing the brush to a substrate; and a transmission member which has an affected point section for receiving, from the actuating point section of the seesaw member, a driving force given to the force point section, the transmission member transmitting, to the brush, a pushing force for pushing the brush to the substrate, wherein the seesaw member is supported by the support member such that the seesaw member is swingable along a vertical plane; the pushing actuator is disposed to give a driving force to the force point section of the seesaw member from under the force point section; and the transmission member includes a shaft which extends down to a position under the actuating point section of the seesaw member, a lower end of the shaft being connected to the brush.
