Abstract
An operation member (51) is fixedly secured to a right portion of a relief member (29) inserted into a housing (20). An annular transmission member (52) externally fitted to the operation member (51) is supported by a guide groove (62) so as to be vertically movable and is urged downward by a spring (74). When the relief member (29) doesn't perform the relief operation, a detected portion (65) of the transmission member (52) is made to access a detecting portion (68) of a proximity switch (14) by the operation member (51). At the time of the relief operation, the relief member (29) and the operation member (51) are rapidly moved rightward, so that the detected portion (65) is spaced apart from the detecting portion (68) by the spring (74).
