Abstract: A tensioner is provided with a female screw member for the tension adjustment of a belt or a chain screwed with a male screw provided a rotation force by a spring and a bearing in which the female screw member is inserted and constrains the rotation of the female screw member.In this tensioner, an outer form of the female screw member is formed so as to correspond to a bearing hole of the bearing. By this, an approximately whole length of the female screw member is able to slide through the bearing hole, and the stroke length of the female member can be secured sufficiently even if the size of the device in a tension controlling direction is shortened.

Abstract: A lock arm is rotatably provided on a base bracket. A ratchet is rotatably disposed on a shaft member provided at an end portion of the lock arm. A distal-end claw portion of the ratchet is shaped to be engageable with reverse motion preventing teeth formed on the base bracket. A stopper wall is provided on a proximal end portion of the lock arm. In the state in which an engaging portion of the trigger lever abuts upon the stopper wall, an end portion of the trigger lever is supported by a movable body. Thereby, the lock arm is held in a normal position. The movable body moves from a first position toward a second position at the time of a collision. A support shaft or the center of rotation of the trigger lever is located on a higher level than a location where the lock arm is engaged with the trigger lever. The movable body is provided with a recess in which the end portion of the trigger lever is put when the movable body has moved from the first position to the second position.

Abstract: A clamp structure having a metal band body is mountable on a surface to be clamped. Small projections rising substantially vertically are formed on an inner lap portion of the metal band body. Receiving holes having an edge portion engageable with the projections are formed in an outer lap portion of the metal band body. A first tool receiving portion is formed on the outer lap portion of the body. A second tool receiving portion and a terminal holding portion are provided on an intermediate portion positioned in the longitudinal direction of the metal band body. The terminal holding portion has an opening for receiving the first end of the body when the projections are inserted into the receiving holes to fasten the metal band body. A temporary attaching means having a passage provided between the terminal holding portion and the projections temporarily attaches the metal band body by constraining the outer and inner portions to be engaged with each other when the metal band body is being fastened.
