<p>PURPOSE:To mount and dismount a tool easily and rapidly by closely fitting the tool in a clearance formed between a bottom plate and a support member so as to install it pressingly on the support member by an elastic pressing member, removing a pressing force of the elastic pressing member, and also removing the tool. CONSTITUTION:A tool 160 is inserted between a support member 140 and a tool mounting part 121 of a bottom plate. It is then pressed against the support member 140 by the self-elasticity of an elastic pressing member 150. The tool 160 is pressed by a projected part 111 of a cushion material 110 also at a hole part 130, becomes difficult to be disengaged by an engaging claw 144, and supported on the bottom plate. When it is removed, the free end 156 side of the elastic pressing member 150 is pressed to the inside of a seat by a finger to deform elastically. Thus a clearance between the support member 140 and a stepped part 158 is made larger than the wall thickness of the tool 160, and the tool 160 can be taken out.</p> |
