Abstract
An engaging portion, formed at an axial end of an intermediate member, is engageable with a slide sleeve. A cylinder has an elongated hole with an axial length longer than a shifting distance of the intermediate member. The slide sleeve includes an annular member and a slide member. The annular member has an inner cylindrical wall engageable with the engaging portion of the intermediate member and a projection extending in a radially outward direction passing through the elongated hole beyond an outer surface of the cylinder. The slide member is coupled around the outer surface of the cylinder and is slidable in the axial direction of the cylinder. One axial end of the slide member, positioned closer to a working tool, is engaged with the projection of the annular member. The other axial end of the slide member is urged toward the working tool by an urging member.
