First Claim
1. A vehicle having a mounting structure which holds a battery pack in which batteries are vertically stacked, wherein said vehicle comprises:
- a left side member and a right side member, extending along a front-to-rear direction of the vehicle and positioned on opposite sides of said battery pack, and wherein the left side member and the right side member are spaced in a left-to-right direction of the vehicle;
a floor panel supported by said left side member and said right side member, said floor panel at least partially defining an opening;
a suspension having arm portions supported to be rotatable at lower portions of said left side member and said right side member, anda left coil spring and a right coil spring respectively arranged between said left and right side members and said arm portions,wherein said battery pack is installed inside said opening of said floor panel, and a front portion, with respect to the front-to-rear direction of said vehicle, of said battery pack is located between said coil springs, andsaid opening having a width dimension extending in the left-to-right direction of the vehicle, and said battery pack having a width dimension extending in the left-to-right direction of the vehicle, wherein the opening and the battery pack are configured to have a tapered shape such that, in a plan view of said vehicle, the width dimension of the battery pack and the width dimension of the opening decrease toward a front side of the vehicle, and wherein the tapered portion of the opening and the tapered portion of the battery pack are located in a vicinity of rear portions of the coil springs, andwherein said battery pack includes a lower portion at a lower side of said floor panel and an upper portion at an upper side of said floor panel, wherein the battery pack is configured such that, in a side view of said vehicle, a front end of said lower portion of the battery pack is located closer toward a front side of the vehicle than a front end of said upper portion of the battery pack.

Abstract
A vehicle battery pack mounting structure that suppresses vibrations of a floor panel while making a shock absorbing space between the battery pack and vehicle exterior members large by effectively utilizing a space between coil springs. The battery pack mounting structure includes a pair of left and right side members and a cross member for supporting the battery pack. A pair of left and right coil springs is installed at these side members and function as suspension members. The battery pack is installed inside an opening of a floor panel between the coil springs, and also between the coil springs, a front portion of the battery pack has a tapered outer surface that becomes narrower as it enters deeper into a space between the coil springs. The opening of the floor panel also has a tapered edge shape.
