The pawl member is secured to the pivot shaft to move therewith. An open lever is secured to the pivot shaft so that the open lever and the pawl member pivot like a single unit. A detecting lever is pivotally connected to the pivot shaft. A first structure is provided for pivoting the detecting lever in a first direction to a given position only when the open lever is pivoted in the first direction. A second structure is provided for retaining the detecting lever in the given position even when the open lever is pivoted back in a second direction opposite to the first direction. A detecting switch is actuated by the detecting lever when the latter comes to the given position.
