Yes. A fraud prevention structure is configured by inserting a fraud prevention member 52, which is a single band, into the two grooves 51. Each groove 51 is formed in a straight line so as to open the front outside the outer wall 47.

  The fraud preventing member 52 is made of an elastically deformable material such as an elastomer such as a reester elastomer, a soft synthetic resin such as vinyl acetate resin, silicone rubber, natural rubber, polyethylene, or polypropylene. The soft synthetic resin means a resin having a lower hardness than a hard synthetic resin such as polyester or polyacryl in addition to the polycarbonate forming the decorative bodies 41 to 43.

  4 and 5, the tamper-proof member 52 extends along the two grooves 51 formed in the left corner ornament 42 and the arc-shaped outer surface of the inner wall 45 located therebetween. It is formed into a shape. That is, the fraud prevention member 52 is a belt plate as a generally rectangular thin plate with a central portion in the longitudinal direction bulging outwardly to the left.

  Referring to FIGS. 5 and 6A, the tamper-proof member 52 has a portion inserted into each groove 51 corresponding to the presser-preventing protrusion 53 formed below each groove 51. An extending portion 54 extending from the end toward the left outward is formed. The fraud prevention member 52 has a thin-walled distal end portion 55 that extends obliquely to the left outside toward the front. In FIG. 3, the tip 55 can be seen as the elastic member 52.

  Referring to FIG. 4 which is a perspective view seen from the left outer side, the tamper-proof member 52 configured in this manner is pushed by sliding it into the groove 51 of the left corner ornament 42 from above (or below).
