摘要： PURPOSE:To regulate play to an optimal quantity, by providing a base which is fitted with a movable bearing and has a fitting hole and a communication hole for causing the fitting hole to communicate with an end face of the base and by securing the base by a projections made by pressure deformation caused through the communication hole. CONSTITUTION:After one end 4 of a rotary body 1 is tentatively fitted in the mortise 5 of a fixed bearing 3, a movable bearing 8 is inserted into the tapped hole 23 of a side wall 22 and the fitting hole 19 of a boss 18. The movable bearing 8 is moved leftward further while a screw part 13 is engaged in the tapped hole 23. As a result, the other end 9 of the rotary body 1 is fitted in the mortise 10 of the movable bearing 8. The movable bearing 8 is then displaced to such a position that the play of the rotary body 1 due to the thrust is optimized. The play is thus adjusted. After that, a pressure deforming implement is inserted into the communication hole 21 to deform the body of the movable bearing 8 by pressure to provide a recess 24 and projections 25. Since the projections 25 are tightened on the inside surface 26 of the fitting hole, the movable bearing 8 is secured on a base 16.

摘要： PURPOSE:To simplify the shape of a push up spring, decrease material loss and reduce cost by placing the push up spring without passing the axial center of an unlocking wheel and and hour wheel. CONSTITUTION:The shaft 14 is inserted into the positioning hole 17 of the push up spring 16 and so held between a boss 11 and another plate 20 that outer end of the width is restrained by the wall 15 of the boss 11, and a projection 18 is pressed by the plate 20 and held along a slanted face 13 of the boss 11. The push up spring 16 is placed without passing through axial center of the unlocking wheel 1 and hour wheel 5, and the position of a projection 19 and whole supporting position are so set that acting point of elastic pressing force is positioned in an extent Z formed by connecting an unlocking projection 8 and three of projection drop holes 4. When the unlocking projection 8 and projection drop holes 4 coincide, the hour wheel 5 moves in axial direction, and the tip of the push up spring 16 comes into contact with a fixed contact plate 21 and alarm sound is produced.

摘要： PURPOSE:To take out the parts having coaxial structure at an assembled state by following method in which the part with a shaft and the part with a shaft tube are simultaneously formed apart in the axial direction, and after molds are opened the shaft part is inserted into the shaft tube and is taken out. CONSTITUTION:A pair of side cores 5 spaced on both side are arranged between molds 3 and 4 of a pair which are attached to a stationary die plate 15 and a movable die plate 16 kept on a stationary fixing plate 17 and a receiving plate 18. A core pin 6 which is connected to the die 4 and whose small diameter part 21 is inserted into the die 3 is equipped between these cores 5. The cavity 31 of a first member 1 with a hollow part 11 between the mold 3, the core 5 and the pin 6, and the cavity 32 of a second member 2 with a shaft tube 13 through which the shaft 11 will be inserted, between the core 5, a large diameter part 22 and the mold 4. These two cavities 31, 32 are constructed. After synthetic resin is filled into the cavity 31 and 32 and the members 1 and 2 are simultaneously formed apart in the axial direction, the molds are released and the cores 5 are opened by an angular pin 24 and then an ejector pin 7 is protruded in the axial direction of a pin 6, thereby inserting the shaft 11 of the member 1 into the shaft tube 13 of the member 2.

摘要： PURPOSE:To make it possible to accurately perform the setting of alarm time, by allowing a manipulating part, which is fixed to an alarm wheel and provided with a hand part, to position so as to be exposed to a front surface of a time dial at the outer periphery thereof. CONSTITUTION:When the setting of alarm time is performed, an alarm dial is directly rotated to set its hand part to a desired alarm time dial 3b and an alarm set manipulating part 9 is brought to an alarm setting position. Because a push-up spring 17 and a fixed contact plate 18 are separated in this state, the alarm pawl 16b of a hr wheel 16 is fallen in the pawl falling hole 16a of an alarm wheel 15 and the push-up spring 17 is contacted with the fixed contact plate 18 to allow a sounding body 19 to generate alarm sound.

摘要： PURPOSE:To produce simultaneously a pair of members to be engaged each other by following method in which a relatively long part is formed between the fixed point of a second member to a base plate and the engaging point of the second member to a first member and a gap is prepared between said members, and the after both parts are simultaneously formed, both parts are caused to be engaged each other by contraction of the second member. CONSTITUTION:A first member 1 is made of synthetic resin and its shaft part 1b is capable of rotation and movement on a base plate 3 such as a lever for changing frequency. A second member 2 has legs 2c sufficiently long compared with the length of the member 1 and is made of synthetic resin. A gap 4 corresponding to the thickness of mold is arranged between the contact point 1a of the member 1 and the contact point 2a of the member 2. In this condition, the members 1 and 2 are simultaneously formed on the base plate 3 by an outsert forming process, and thereafter, elastic contact is obtained between the contact point 2a of the member 2 and the contact point 1a of the member 1 by contraction of the member 2. Consequently, both members may be caused to be engaged each other without looseness between said member and any treatment after forming is unnecessary.
