Claims

[Claims for Utility Model Registration] (1) The distance between the stage and the objective lens is changed through coarse movement means for relatively coarsely changing the distance between the stage and the objective lens, and a deceleration mechanism supported by the coarse movement means. A focusing device for a microscope, comprising a fine movement means for making a relatively fine change, a drive means that can be connected to the fine movement means, and a locking means that can lock the coarse movement means to a microscope body. (2) The locking means includes a protruding piece that protrudes from the outer periphery of the rotating operation part of the coarse moving means and is provided with a through hole, and a rod-shaped member that is inserted into the through hole and the insertion hole of the microscope body. A focusing device for a microscope according to claim (1) of the utility model registration, characterized in that it consists of: (3) The locking means is slidably supported by a first engaging part provided on the rotation operating part of the coarse moving means and has a first engaging part located at a position facing the first engaging part. A fixing member provided with a second engaging part that can engage with the first engaging part, and a sliding rotation of the fixing member that is fixed to the microscope main body and fits into a guide hole formed in the fixing member. and an elastic member that urges the fixing member toward the first engaging portion. A focusing device for a microscope according to claim (1) of the utility model registration.
