PROBLEM TO BE SOLVED: To absorb the mount play of a front panel on a housing, without increasing the size precision of components. SOLUTION: On an engagement piece 15 provided to a front panel 13, an engagement projection 16, whose tip is formed in an outwardly hooked shape is formed, an engagement part 17 on the side of a housing 11 with which the engagement projection 16 engages is formed into a hole shape, and the surface of the engagement projection 16 which faces the side of the front panel 13 is formed into a slanting surface 16a which slants to the tip side of the engagement piece 15, and the slanting surface 16a is made to abut against the longitudinal wall surface 17a of the engagement part 17 which is positioned in the front part of the housing 11, thus constituting a play-absorbing means 10.
