Claims

[Claims for Utility Model Registration] (1) A case in which a turntable and its drive motor are mounted is made of synthetic resin, and a circular recess for installing the turntable is formed in the center of the upper wall of the case. A record player case characterized in that a circular convex portion is formed concentrically at the bottom of the circular recess, and a circular vibration isolating material is placed on a circular upper wall of the circular convex portion. structure. (2) The vibration isolator for a record player case as set forth in claim 1 of the utility model registration claim, characterized in that a cylindrical portion that fits on the circumferential surface of the circular convex portion is integrally formed on the peripheral edge of the vibration isolator. structure. (3) The circular convex portion is formed in an annular shape, and the inner peripheral surface of the circular convex portion connects a large diameter portion that forms a space for arranging the drum portion of the turntable and a small diameter portion that forms a space for arranging the pulley. The vibration isolating material is formed into an annular shape, and the inner and outer circular edges of the vibration isolating material are formed with an inner cylinder part and an outer cylinder part that fit into the inner and outer circumferential surfaces of the circular convex part. A vibration-proof structure for a record player case according to claim 2 of the utility model registration claim, characterized in that: (4) A positioning protrusion is formed on the circular upper wall, a protrusion engagement hole is formed in the vibration damping material, and the positioning protrusion is inserted into the protrusion engagement hole. A vibration isolation structure for a record player case according to any one of claims 1 to 3 of the utility model registration claims.
