摘要： PURPOSE:To enable a propelling body to be exactly controlled in the propelling direction by setting a cam for increasing the retaining pressure of a retaining device reversibly along with operation for moving a retaining section main-body in the propelling direction in a state that the propelling body is retained with the retaining device. CONSTITUTION:A retaining section 17 for retaining a propelling body B consisting of a propelling head and a propeller pipe 2 connected to the head, is set. The retaining section 17 is composed so that a retaining device 7 for retaining the propelling body B removably may be internally fitted in a retaining section main-body 17A movably in the axial core direction of the propelling body B. After that, between the retaining device 7 and the retaining section main-body 17A, a cam mechanism 8 is set. Then, along with operation for moving the retaining section main-body 17A in the propelling direction of the propelling body R, in a state that the propelling body B is retained with the retaining device 7, with the action of the cam mechanism 8, the retaining pres sure of the retaining device 7 to the propelling body 8 is reversibly increased.

摘要： PROBLEM TO BE SOLVED: To simultaneously and favourably connect and actuate a plural number of connecting devices while securing a sufficient hooking margin of an engaging part and an engaging surface without extremely increasing a diameter of the engaging part by setting and devising fit tolerance between a male member and a segment main body. SOLUTION: Both of a first clearance d1-d2 between an inside diameter d1 of a small hole part 11a of a stepped hole 11 to install a male member 3 and an outside diameter d2 of a shaft part 6 of the male member 3 and a third clearance d3-d4 between an inside diameter d3 of a large hole part 11b of the stepped hole 11 and an outside diameter d4 of a drum part 7 are set larger than a second clearance d5-d4 between an inside diameter d5 of an insertion port 4a of the female part 4 and the outside diameter d4 of the drum part 7 of the male member 3 on a connecting device forming the engaging part 5 to work to stop falling by being engaged with an engaged part 13 of the male part 4 by elastic recovering deformation in the diametrical extending direction after inserting a head end part of the male member 3 in the female part 4 with elastic diametrical contracting deformation.

摘要： PROBLEM TO BE SOLVED: To provide a connecting device sufficient in strength capable of improving force of a male member against shearing force and resisting the shearing force acting on between segments after connection. SOLUTION: A shaft part 6 to screw on a segment 2a and a drum part 7 larger in diameter than the former and furnished with an engaging part 5 on its head end are provided on a male member 3, the root side of the drum part 7 is fitted in a second segment 2 and a second segment side end position of a slit 10 is moved to the side of the first segment 1 from a mating surface (h) of the both segments 1, 2 on a connecting device A to connect both segments 1a, 2a in a falling stop state by insertion of the male member 3 into a female part 4 by forming the engaging part 5 to work to stop falling by elasticity diametrical extending recovering deformation after insertion of a first segment 1a into the female part 4 on a head end of the male member 3 of the second segment 2a and forming the slit 10 to facilitate elastic deformation on the male member 3.

摘要： PROBLEM TO BE SOLVED: To produce a connection force of certain magnitude by merely conducting a push-in operation. SOLUTION: In the connector, a first member 1 having a first abutting part A1 in which a first dovetail groove M1 is formed and a second member 2 having a second abutting part A2 in which a second dovetail groove M2 is formed are provided. In order to connect the member 1 and the member 2 to each other, a pair of holding parts K1, K2 are provided, which can be inserted respectively into the parts M1, M2 of the parts A1, A2 disposed in opposition to each other so that both the parts K1, K2 communicate with each other. The interval between the parts K1, K2 increases with distance along a push-in direction X1. In this case, protruding members T are provided respectively on the rear ends of the parts K1, K2 in the direction X1 so that the members T can deform outward by being subjected to a certain pressure.
