Abstract: A structure that enables response with consideration to emergencies in a saddle-ride type vehicle including an electronic key authentication system. The saddle-ride type vehicle includes a smart lock module that enables a start operation for an engine and an unlocking operation for a handlebar and enables unlocking of a seat and a fuel lid, through an electronic key authentication system; and a vehicle body cover disposed around the smart lock module. The smart lock module includes an insertion portion into which an emergency release key that allows the seat to be unlocked in an emergency is inserted. The insertion portion is located in the smart lock module to the vehicle rear side.

Abstract: A sand pile driving method for making a sand pile which does not cause trouble in terms of strength even at a soft point in the actual ground, and enables secure limitation of the increase in total construction time and total amount of sand. A compaction procedure is a procedure for compacting a granule pile 15 by pressing and rotating the casing pipe 13 downward. This is performed based on thrust force P by which the casing pipe presses a granule pile and a driving torque T for rotating the casing pipe against a granule pile.
