Abstract: A resonance shear measurement device (1) of the present invention includes an upper unit (10) having a piezoelectric element (15), an upper disk substrate (16), and a spring (17), and a lower unit (11) having a lower disk substrate (14), in which a sample insertion portion (21) is formed between a lower surface of the upper disk substrate (16) and an upper surface of the lower disk substrate (14), the piezoelectric element (15) and the upper disk substrate (16) are vibratably connected to a fixed apparatus 30 via the spring (17), a strain gauge (19) is attached to the spring (17), and by applying an AC voltage to the piezoelectric element (15) while changing a frequency of the AC voltage, a response voltage at the resonance from the strain gauge (19) due to a vibration of the upper unit (10) is measured.

Abstract: Provided is a rear structure of a vehicle. The rear structure includes: a rear opening at a rear of a vehicle body; and an opening-closing member configured to open and close the rear opening. The opening-closing member has cushioning members respectively disposed on both Side portions in a vehicle body width direction. The rear opening has contact members respectively disposed on both side borders in the vehicle body width direction, the contact members being contactable with the cushioning members. Each cushioning member has two surfaces, one of which extends in a vehicle body upward-downward direction and the other of which extends in the vehicle body width direction. The two surfaces of each cushioning member are disposed to be contactable with a corresponding one of the contact members.
