Abstract
A push-up device includes a case, a rod juts out from inside the case so as to adopt an advanced position, a rod biasing member biases the rod in a jutting out direction pushing the rod out from inside the case, a lock mechanism that includes a slide cam that moves together with the rod in the jutting out direction and a rotation cam that is relatively rotatable with respect to the slide cam about the axis of the rod, with the lock mechanism positioned between the case and the rod, and locking the rod in a retracted position in the case by the rotation cam engaging with the slide cam and rotating due to the rod being pressed in against biasing force of the rod biasing member, and a rotation cam biasing member that biases the rotation cam toward the jutting out direction.
