Claims

[Scope of utility model registration request]

A concave groove extending in a straight line is formed on the opposing surfaces of the stay-side block member fixed to the lower part of the back mirror stay and its counterpart block member, and the handrail portion of the upper swing body is held between both concave grooves. In the back mirror mounting device mounted in this manner, grooves perpendicular to each other in a cross shape are formed on the opposing surfaces of the stay-side block member and the mating block member, and the vertical or horizontal component of the handrail portion is formed. A construction vehicle characterized in that both of the block members can be attached to either the vertical or horizontal component of the handrail section when the rearview mirror is moved to a parallel state. Back mirror mounting device structure.
