Abstract: A mouse and a stay thereof are disclosed. The mouse includes an up/down guide part formed on a body, and a finger supporting part supported by the up/down guide part so as to move up and down and including supporting arms extended opposite to each other in a width direction. The mouse stay includes a base plate to movably keep the mouse on, a connecting part hingedly connected to a rear end portion of the base plate so that the connecting part can be pivoted to be folded or spread toward/from an upper surface of the base plate, and an extending part hingedly connected to an upper end portion of the connecting part so that the extending part can be pivoted to be folded or spread toward/from a front surface of the connecting part. A mouse cable is connected to a front end portion of the extending part.

Abstract: Disclosed is an escape descender for emergency escape movably installed to an escape line. The escape descender includes a case defining a vertical rope passage therein, a roller support having a lateral opening facing the rope passage and adapted to move close to or away from the rope passage, a rotatable holding lever to cause the opening of the roller support to be close to or away from the rope passage, movable rollers arranged in the roller support so as to partially protrude from the opening, stationary rollers arranged in the case such that an outer periphery of each stationary roller opposes an outer periphery of the corresponding movable roller. One of the stationary rollers is rotatably supported on a drum of the case and incorporates a brake lever provided with a pad, the brake lever being centrifugally rotated to cause the pad to come into contact with the drum.

Abstract: A lifting device for a tow car is disclosed. The lifting device includes a guide bracket fixed to a tow car, a lifting bracket slidably connected to the guide bracket, a lifting driving cylinder to move the lifting bracket up and down, a folding bracket pivotally connected to the lifting bracket, a rotating bracket inserted into the folding bracket, an extendable bracket inserted into the rotating bracket so as to move in an axial direction, an extension driving cylinder to move the extendable bracket forward and backward, a connecting unit connected to the extendable bracket and a car to be towed, and a winch unit connected to a car to be towed so as to draw the car to be towed, or connected to any one of the folding bracket, the rotating bracket, the extendable bracket and the connecting unit so as to integrally lift up them.
