Abstract: A grommet G according to the present invention is provided with, on the outer side of a second flexible portion 22, a padding portion 4. With this, of a pressing force F which acts from the cylindrical base part 1 side to the seal portion 3 side, a panel parallel component F1 parallel to a dash panel DP is hardly transmitted. On the other hand, a panel vertical component F2 vertical to the dash panel DP is easily transmitted. Consequently, the panel vertical component F2 becomes relatively large, and even if the seal portion 3 is brought into contact with the dash panel DP by acting the pressing force F from the oblique direction, the rolling-up caused by the occurrence of the inclination of the seal portion 3 can be suppressed.

Abstract: An all-solid-state battery system according to this application includes an all-solid-state battery and a charging apparatus, in which the all-solid-state battery includes a positive electrode, a negative electrode, and a solid electrolyte layer located between the positive electrode and the negative electrode, the negative electrode contains a negative-electrode active material and a solid electrolyte, the negative-electrode active material contains a lithium titanium oxide, and a negative electrode discharge utilization rate X calculated using the following equation is 134 mAh/g or less. The negative electrode discharge utilization rate X=battery capacity Q (mAh)/mass of the negative-electrode active material in the negative electrode (g), where the battery capacity Q is a discharge capacity (mAh) obtained when the battery is charged with a constant current at 0.2 C to the upper limit charging voltage, charged with a constant voltage to 0.002 C, and discharged at 0.002 C to 1 V.
