A connecting structure includes a connecting pin, a pin catch, a biasing member, and a holder. The connecting pin has a first portion, a second portion thicker than the first portion, and a step therebetween and connects a connecting object and a connected object (objects) by being inserted into their insertion holes. The pin catch moves in a recess in one of the objects in moving directions that are not an extending direction of the insertion holes and has a pin engagement portion that engages the step. The biasing member biases the pin catch in one of the moving directions. The holder is on the one of the objects and transitions, in response to user operation, to a first state where the holder and the biasing member holds the pin catch or a second state where the pin catch is detachable from the recess.

Connecting structure and wearable device

A connection structure includes: a connection pin that includes a first part and a second part between which a step is formed and that connects a first target and a second target by being inserted in an insertion hole; and a pin locker movable in a moving direction in a recess formed in either the first or second target. The pin locker has a pin engaging part that engages with the step of the connection pin and a pin insertion part. One of the recess and the pin locker has a first abutting part, and another has a first abutted part. When the pin locker is at a specific position and the first abutting part abuts the first abutted part, at least either an orientation or a position of the pin insertion part is limited such that the second part is allowed to pass through the pin insertion part.

Connection structure and wearable device

A dial including a base member having a sheet shape containing reinforced fibers, and a decorative member provided on one surface of the base member containing a brittle material.

Dial and timepiece

A pointer including a pointer body constituted by a plate member, an engraved section provided in at least one of front and back surfaces of the pointer body excluding an edge of the pointer body, and a reinforcing section provided at the edge of the pointer body by the engraved section.

Pointer and timepiece

A pointer including a thick section formed on a pointer body in a manner to be thicker than a thickness of the pointer body, an accommodation section provided in the thick section in a manner to penetrate through a front and back of the thick section, and a luminous member provided in the accommodation section.

A pointer including a pointer body made of a material sheet formed by a plurality of fiber sheets having carbon fibers arranged in one direction being laminated together with arrangement directions of the carbon fibers being varied.

Pointer and pointer manufacturing method

A pointer including a pointer body formed using a carbon fiber textile sheet having a carbon fiber woven thereinto.

A watch case having a through-hole, an operating member including an operating shaft to be inserted to the through-hole of the watch case, an exterior member mounted on the operating member and configured to be displaced in a shaft direction of the operating shaft and be rotated together with the operating member, and a buffer member located between the operating member and the exterior member are provided. Therefore, when the exterior member receives impact from outside, the impact can be buffered by the buffer member. As a result, the operating member can be prevented from being damaged because the impact from the outside is not directly transmitted to the operating member, thereby improving impact resistance.

Switch device and timepiece

With a dial for a timepiece comprising a decoration member having a plurality of through holes formed vertically on a luminescent member , the cross-sectional area of lower-side holes of the decoration member is formed to be larger than that of upper-side holes . Therefore, even if a substrate is thick, the diameter of the upper-side holes of the through holes can be formed to be small sufficiently. Moreover, compared to a dial size for a timepiece wherein the decoration member is placed on the luminescent member , the diameter of the through holes of the decoration member is small. Thus, it is possible to take in enough light from the luminescent member through the lower-side holes to ensure the sufficient amount of light through the through holes . It is possible to obtain sufficient illuminance for the dial.

Dial for timepiece, manufacturing method thereof and timepiece

A dial for timepiece is provided which includes a decoration member having a through hole, and a luminescent member disposed under the decoration member. A first surface processed layer is provided on an upper surface of the decoration member, and a second surface processed layer having a light-transmissive property is provided on an upper surface of the luminescent member. When the luminescent member is turned on, light emitted from the luminescent member is transmitted through the second surface processed layer and passes through the through hole of the decoration member. Because the transmitted light illuminates the upper surface side of the decoration member partially in accordance with the through hole, the dial is visible even in a dark place. In addition, decoration effects can be achieved by both the first surface processed layer and the second surface processed layer in accordance with the through hole.
