  • Publication number: 20250236231
    Abstract: A utility vehicle 100 is a vehicle, and includes a base 1, a cargo bed 2, a lift spring 3, and a lock 4. The lift spring 3 is located offset to one side with respect to the center of the cargo bed 2 in a vehicle width direction. The lock 4 includes a first lock 4A and a second lock 4B. The first lock 4A has a first striker 5A, a first hook 6A, and a lock spring 7. The second lock 4B has a second striker 5B and a second hook 6B. The second hook 6B is coupled to the first hook 6A so as to rotate integrally with the first hook 6A. When the cargo bed 2 transitions from a lifted state to a lowered state, the first hook 6A rotates in a reverse direction of a biasing direction against the elastic force of the lock spring 7 by contacting the first striker 5A, and thereafter, rotates in a forward direction which is the biasing direction by the elastic force of the lock spring 7 and is engaged with the first striker 5A.

  • Publication number: 20250014846
    Abstract: A trigger switch capable of suppressing wear of a sliding electrode part and a device including the trigger switch are provided. A trigger switch includes a front sub-brush and a rear sub-brush that, when a drive part is driven by a movement of a trigger caused by a push-in operation to the trigger, move from an on-position where they contact a front sub-electrode and a rear sub-electrode on a substrate to an off-position where they do not contact the front sub-electrode and the rear sub-electrode. As the front sub-brush and the rear sub-brush move from the on-position to the off-position, a contact between the front sub-brush and the rear sub-brush and the substrate are released.
