Abstract
A soundproof member is capable of being lightweight and simplifying the manufacturing process. The soundproof member which covers an object includes a sound absorbing body molded from foamed resin and a cover body molded from foamed resin. Multiple fitting concave units are provided on a circumferential side surface of the sound absorbing body, and multiple fitting convex units are provided on a side wall of the cover body. The sound absorbing body and the cover body are integrated by fitting the fitting concave units and the fitting convex units.
Claims6
A soundproof member which covers an object having a concave unit on an outer surface thereof, comprising:
- a sound absorbing body, being a plate-shaped member made of foamed resin and comprising a first surface which has a convex unit accommodated in the concave unit of the soundproof member and covers an outer surface of the object, a second surface which is a surface opposite to the first surface, and a circumferential side surface which connects the first surface and the second surface and is an inclined surface that slopes so that the first surface falls within a projection range of the second surface when viewed from the second surface side;
- and
- a cover body, being a concave member made of foamed resin and comprising a bottom unit which covers the second surface of the sound absorbing body and a side wall which stands upright from an outer edge of the bottom unit toward the first surface side of the sound absorbing body so as to slope outward in a surface direction of the sound absorbing body, and surrounds the circumferential side surface of the sound absorbing body, wherein
- a plurality of fitting concave units that open outward in the surface direction of the sound absorbing body and communicates in a thickness direction of the sound absorbing body are provided at predetermined intervals in a circumferential direction on the circumferential side surface of the sound absorbing body, and
- a plurality of fitting convex units that protrude inward in the surface direction of the sound absorbing body and continues in the thickness direction of the sound absorbing body are provided at positions facing the plurality of fitting concave units in the circumferential direction on an inner surface of the side wall of the cover body.

- a sound absorbing body, being a plate-shaped member made of foamed resin and comprising a first surface which has a convex unit accommodated in the concave unit of the soundproof member and covers an outer surface of the object, a second surface which is a surface opposite to the first surface, and a circumferential side surface which connects the first surface and the second surface and is an inclined surface that slopes so that the first surface falls within a projection range of the second surface when viewed from the second surface side;
- and
- a cover body, being a concave member made of foamed resin and comprising a bottom unit which covers the second surface of the sound absorbing body and a side wall which stands upright from an outer edge of the bottom unit toward the first surface side of the sound absorbing body so as to slope outward in a surface direction of the sound absorbing body, and surrounds the circumferential side surface of the sound absorbing body, wherein
- a plurality of sound absorbing side fitting convex units that protrude outward in the surface direction of the sound absorbing body or a plurality of sound absorbing side fitting concave units that open inward in the surface direction of the sound absorbing body are provided at predetermined intervals in a circumferential direction on the circumferential side surface of the sound absorbing body, and
- a plurality of cover side fitting concave units that open inward in a surface direction of the cover body and fit opposite to the sound absorbing side fitting convex units or a plurality of cover side fitting convex units that protrude outward in the surface direction of the cover body and fit opposite to the sound absorbing side fitting concave units are provided in the circumferential direction on an inner surface of the side wall of the cover body.
