摘要:
In a solder reflow process, a vibration motor is stably mounted on a circuit board by changing the design of a partial shape of a soldered motor holder without changing the design of a vibration motor body and securing a sufficient soldering area to completely perform solder bonding to prevent a soldered portion of a motor holder from peeling off the circuit board. A surface mount type vibration motor is provided, wherein the pedestals of a motor holder include the support plates that are in contact with stationary lands on a surface of a circuit board and extend in the axial direction of an output shaft, end portions of the support plates are arranged between the position of an eccentric weight and the end surface of the eccentric weight along the axial direction, and the support plates are not arranged just under an axis of said output shaft where the distance between the weight and the circuit board is minimum.

A surface mount-type vibration motor and an installation structure for a surface mount-type vibration motor, where soldered portions are prevented from separating from a circuit board without requiring any design change in a vibration motor body. A section where a motor holding section of a motor holder and motor support sections of the motor holder are connected is bent in an arc shape having elasticity to form the motor holder, the motor holding section holding a vibration motor body to which an elastic holder is attached, the motor support sections being arranged along a circuit board. First contact sections and second contact sections are formed in the connection section such that distal ends of the first and second contact sections are of a band-like shape projecting toward the inside of the vibration motor body. The motor holder reduces a load applied to portions where the surface mount-type vibration motor is soldered to the circuit board and also improves bonding strength.

[Object] To provide a vibration actuator capable of obtaining sufficiently sensible vibration with a flat, thin shape maintained.[Solving Means] Two magnets of a moving part are fixed in a direction where magnetic forces of the magnets are repulsed each other, and the moving part is disposed inside a coil of a fixed part in a housing, so that the moving part collides with the housing when an alternating current is applied to the coil. Therefore, vibration is transferred to the case through the collision. Accordingly, it is possible to implement a miniaturized vibration actuator capable of generating a sufficiently sensible vibration.

An outboard motor includes a cooling water passage that guides cooling water to cool an exhaust passage and a cylinder unit. A cooling water intake port draws external cooling water into the cooling water passage. A water pump draws cooling water into the cooling water intake port and supplies the cooling water to the cooling water passage. A thermostat is arranged in the cooling water passage downstream of the catalytic converter and the cylinder unit. A first bypass passage is connected to a first connecting section provided on the cooling water passage. The first connecting section is provided along the cooling water passage at a position farther downstream than the catalytic converter and farther upstream than the thermostat.
