<p>PROBLEM TO BE SOLVED: To exactly fix many batteries through a battery box as well as to facilitate checking and maintaining a battery in a vehicle provided with an electric motor for running. SOLUTION: In this battery unit, a battery box 1 has frame brackets 3 which extend parallel to both sides of the bottom face thereof, and a battery chamber 2 has a guide rail 5 which receives the frame bracket 3 and guides the battery box 1 to an accommodating direction via the frame bracket 3. Each frame bracket 3 has a locking pin 6 which can advance to or retreat from the guide rail 5 through an axial hole 7 which penetrates in an orthogonal direction thereof, and the guide rail 5 has a pin hole 8 into which the locking pin 6 can be inserted at an accommodating position of the battery box 1. At the rear end portion toward the accommodating direction of the battery box 1, an operation handle 12 rotatable on a rotating shaft and link mechanisms 13, 14 which synchronically advance and retreat the locking pin 6 in accordance with rotation of the operation handle 12 between the rotational shaft and each locking pin 6 are installed.</p> |
